Green Textile Finishing: Utilisation of Vetiver Extract for Antimicrobial Home Textile Applications | Chapter 7 | Engineering Research: Perspectives on Recent Advances Vol. 12

 

Home textiles represent one of the fastest-growing segments within the technical textile industry. The home-tech sector includes textile materials intended for household and hygiene-related uses, where sustainability and safety are key requirements. Growing consumer awareness regarding health and cleanliness has increased the demand for textile products with built-in antimicrobial functionality. Among natural plant resources, Vetiveria zizanioides is an abundant and valuable source known for its strong fibres, pleasant fragrance, and inherent antimicrobial properties. In this study, extracts were prepared from Vetiveria zizanioides powder using a suitable solvent system. The extract was subjected to phytochemical screening and chemical component analysis, followed by evaluation of its antimicrobial potential against selected standard microorganisms. Both qualitative and quantitative antifungal tests were conducted on treated fabrics against Aspergillus niger and Candida albicans, while antibacterial activity was assessed against Staphylococcus aureus (ATCC 25923) and Escherichia coli (ATCC 25922), representing Gram-positive and Gram-negative bacteria, respectively. The findings demonstrate the effectiveness of vetiver-based treatments and highlight their potential application in medical and home textile products.

Zizyphus mauritiana as a Source of Tannins with Antibacterial and Antiplasmodial Activities | Chapter 7 | Chemistry and Biochemistry: Research Progress Vol. 8

 

Background: In Africa and other countries where malaria is endemic, traditional medicinal plants are frequently used to treat or cure malaria. Ziziphus mauritiana, a tropical fruit tree species belonging to the family Rhamnaceae, is used in African traditional medicine against different symptoms and diseases.

 

Aim: This study was designed to evaluate tannins extracted from Ziziphus mauritiana as a source of potential antimalarial and antimicrobial agents in Mali.

 

Methodology: The collection of plant materials, tannins extraction, antibacterial activity evaluation were done at the University of Sciences, Techniques and Technologies of Bamako, Mali and antiplasmodial activity assessment at Department of Microbiology and Immunology, Weill Cornell Medicine, New York, United States of America, between September 2013 and February 2014. The tannins were extracted from leaves of Z. mauritiana collected around Bamako, Mali. Antiplasmodial activity was evaluated against 3D7 (chloroquine-sensitive) and Dd2 (chloroquine-resistant) strains of Plasmodium falciparum using the fluorescence-based SYBR® green I method. Antibacterial activity of tannins was evaluated by the disc diffusion method against strains of Escherichia coli, Salmonella Typhi, Streptococcus and Staphylococcus aureus donated by the National Research Institute in Public Health in Mali and collected from infected patients suffering from different diseases. The Kruskal–Wallis H test for data of zone of inhibition was used with the Statistical Package for the Medical Sciences version 17.0.

 

Results: The tannin extracts from leaves of Z. mauritiana demonstrated moderate antibacterial activity (average 7-9 mm diameter of inhibition zone) on tested strains. Tannins extracted from leaves of Z. mauritiana showed moderate antiplasmodial activity against 3D7 P. falciparum (46.9±1.12 μg/mL) and against Dd2 P. falciparum strains (67.8±2.39 μg/mL). They also showed an antibacterial activity on different bacterial strains, showing important inhibition zones. Especially, they were more active on Streptococcus than Escherichia coli, Salmonella typhi, and Staphylococcus aureus.

 

Conclusion: Tannins extracted from Z. mauritiana demonstrated good antiplasmodial and antibacterial activities. It could be regarded as effective and studied for further consideration as a complementary medicine source of antimicrobials against most multidrug-resistant bacteria and other parasites. These data confirm the potential use of tannins as a key element in antimalarial and antibacterial drug development.

Uridine Derivatives as Potential Human Gene Protein Inhibitors | Chapter 5 | Chemistry and Biochemistry: Research Progress Vol. 8

 

Uridine (Urd) is a promising biochemical modulator to reduce host toxicity caused by 5-fluorouracil (5-FU) without impairing its antitumor activity. Elevated doses of Urd are required to achieve a protective effect against 5-FU toxicity, but exogenous administration of Urd is not well-tolerated. Selective inhibitors of human uridine phosphorylase (hUP) have been proposed as a strategy to increase Urd levels. Nucleosides and their analogues are well-known classes of clinically useful medicinal agents with antiviral and anticancer activities. In our study, two new series of nucleoside derivatives were synthesised from uridine (1) through a facile two-step reaction involving direct acylation, which afforded 5′-O-acyl uridine derivatives in reasonably good yields. These intermediates were further converted into two series of 2′,3′-di-O-acyl derivatives to evaluate their antimicrobial activity. The newly synthesised compounds were characterised by physicochemical, elemental, and spectroscopic analyses and subsequently tested in vitro against selected human and plant pathogenic strains. The results demonstrated moderate to good antibacterial and antifungal activities, with the compounds showing greater efficacy against fungal phytopathogens than bacterial strains. Notably, some compounds exhibited superior antimicrobial activity compared with standard antibiotics. Minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) tests were performed for five selected compounds (6, 11, 13, 16, and 17) based on their biological activity. Furthermore, all synthesised derivatives were optimised using density functional theory (DFT, B3LYP/3-21G) to predict their thermal stability and molecular orbital properties. Molecular docking studies were conducted using the human gene-encoded protein 5WS1 to evaluate their binding affinity and interaction modes. Additionally, pharmacokinetic properties were assessed through ADMET and SwissADME analyses, revealing improved profiles. Structure–activity relationship (SAR) analysis was also performed. Overall, these findings suggest that the synthesised compounds could serve as promising leads for the development of novel antimicrobial agents with enhanced biological efficacy for future pharmaceutical applications.

Synthesis and Characterization of Transition Metal(II) Complexes Derived from (E)-N-(4-Methylbenzylidene)-2-((Z)-(4-Methylbenzylidene) Amino)Benzamides: Investigation of Biological Activities| Chapter 10 | Recent Developments in Chemistry and Biochemistry Research Vol. 3

 

We synthesized a novel series of transition metal(II) complexes 5a-h by reacting key transition metals (Co, Cu, Zn, Ni) with the Schiff base 3, derived from (E)-N-(4-methylbenzylidene)-2-((Z)-(4-methylbenzylidene)amino)benzamide. Schiff base 3 was previously prepared by reacting 2-aminobenzohydrazide 1 with 4-methylbenzaldehyde 2. The structures of the metal complexes were characterized using IR, NMR, mass spectrometry, and elemental analysis. We evaluated the synthesized metal complexes for antioxidant, antimicrobial, and antifungal activities. Notably, compounds 5e and 5c exhibited enhanced antimicrobial activity compared to the free ligand. Compounds 5g and 5a showed significant activity against various bacterial strains. Additionally, the hydrated metal complexes 5b, 5d, 5f, and 5h demonstrated moderate to good antimicrobial activity. In terms of antioxidant activity, most of the metal complexes displayed moderate to good activity comparable to ascorbic acid. Our bioassay results highlighted compounds 5e and 5c as effective antimicrobial agents against highly resistant microbial strains.

Spasmolytic Activity, Anti-Inflammatory Potential, and Molecular Docking Studies of Anthranilic Acid Hybrids | Chapter 8| Chemical and Materials Sciences - Developments and Innovations Vol. 3

Anthranilic acid and its analogs have an impressive biological profile; its structural nucleus has been thoroughly studied for the development of pharmaceuticals. Due to the predicted in silico methods spasmolytic activity, we synthesized a hybrid molecule of anthranilic acid and substituted 2-phenylethylamines. Phenylethylamines are serotonin agonists and are building blocks of isoquinoline alkaloids. Therefore, the synthesis of a new hybrid molecule of anthranilic acid and substituted 2-phenylethylamines, is extremely interesting in view of what properties the newly obtained molecule would inherit from both fragments. The current study has shifted towards the synthesis of novel hybrids as spasmolytic and anti-inflammatory agents. DFT calculations and docking simulations were performed on the synthesized compounds. The obtained results from all the experiments demonstrate that the hybrid molecule and its diamides inherit spasmolytic, antimicrobial, and anti-inflammatory capabilities, making them excellent candidates for future medications. Based on the experimental data, we can conclude that a collection of Novel 2-phenylethylamine hybrids were successfully synthesized and they can be considered as antispasmodics and anti-inflammatory drug candidates – alternatives to current therapeutics.

Prospects for the Application of Tryptanthrin and Mostotrin Alkaloids in Therapy and Control of Inter-Specific Interactions in Various Symbiotic Systems: A Review | Chapter 7 | Chemistry and Biochemistry: Research Progress Vol. 6

Tryptanthrin (TR) is one of the most widespread and well-known quinazolinone alkaloids with cytotoxic, antimicrobial and immunomodulatory efficiencies. This secondary metabolite exhibits a large area of biological activity, generating an increasing interest in the synthesis and evaluation of its derivatives and analogues. As main natural sources are known plant species like Polygonum tinctorium and other indigo plants. Currently, a lot of attention has been paid to the studies on the possible bio-regulatory role of TR. Mostotrin (MT) is a synthetic water-soluble analogue of TR, which can expand the spectrum of pharmaceuticals for the treatment of inflammatory, antitumor, infectious diseases, and recently emerging epidemics like SARS-CoV-2. TR and MT derivatives even have capacity for use as important elements of signalling control in inter-species or inter-kingdom relationships of various multi-member microbiomes (community of microorganisms in e.g. the human body) with the host organisms and interactions of microorganisms in diverse marine or earth ecosystems. Recently published studies on the biological activity and probable molecular mechanisms underlying the therapeutic and regulatory actions of TR and MT became the subject of analysis in this mini-review.

Photodynamic Antibacterial B-Cyclodextrin-Modified Cotton Fabric for Medical Applications | Chapter 2 | Chemistry and Biochemistry: Research Progress Vol. 4

The development of medical and hospital textiles is of significant interest, particularly concerning infectious diseases caused by pathogens. Contact with contaminated surfaces can lead to serious illnesses and pose a significant public health problem. The use of cyclodextrins in textiles for the development of biofunctional fabrics represents an interesting alternative for the advancement of dental, medical, and hospital materials. Cyclodextrins can interact with the chemical groups present in cotton fibers, forming a nanostructured surface with specific functional properties, including antibacterial activity. Although there are numerous antibacterial textile finishes, the use of methylene blue as a cyclodextrin host molecule for photodynamic applications in textile materials remains to be investigated. This is because methylene blue is a photosensitive dye capable of generating singlet oxygen (1O2) when illuminated, which inactivates the pathogenic microorganisms that may be present in wounds. The objective of this study was to develop a biofunctionalized and photoactivatable cotton fabric with antimicrobial properties for use in the cosmetic or medical industries. The materials obtained were characterized via scanning electron microscopy (SEM), Fourier transforms infrared spectroscopy with attenuated total reflection (FTIR-ATR), the determination of cotton fabric functionalization dyeing variables, colorimetry, UV-VIS spectrophotometry, degradation of 9,10-anthracenyl-bis (methylene) dimalonic acid (ABDA), photodegradation tests, and microbiological analysis. The antibacterial activity of the functionalized fabrics was evaluated by adopting the AATCC 100—Test Method for Antibacterial Finishes on Textile Materials: Evaluation. The results showed that the textile was functionalized with β-cyclodextrin, mainly evidenced by the appearance of the band at 1730 cm−1, indicating the formation of the ester group. Thus, when exposed to light, the non-functionalized material showed greater photobleaching, about 60%, compared to the material treated with cyclodextrin. This result was also reflected in the ABDA degradation kinetics, with the treated material showing 592.00% (first phase) and 966.20% (second phase) higher degradation than the untreated sample. Finally, the photodynamic activity was determined based on the antimicrobial properties of the textile, showing a reduction of more than 99% without exposure to light and 100% when exposed to light. Methylene Blue appears to be a promising candidate for use as a photosensitizer in cutaneous antimicrobial treatments. It is believed that this study could open avenues for future research and the development of antimicrobial fabrics, as well as demonstrate the efficiency of the treatment with cyclodextrin in relation to photobleaching.

Antimicrobial Properties of Homo Fermenting Lactic Acid Bacteria (LAB) Isolated from Kunu-Zaki (A Spontaneously Fermenting Nigerian Cereal Beverage) | Chapter 8 | Research Perspectives of Microbiology and Biotechnology Vol. 3

 Aim: The present study aimed to determine the antibiotic reaction and adhesion

pattern of antimicrobial homo-fermenting LAB strains in the fermenting slurries of

kunu-zaki, Nigeria.

Background: Lactic acid bacteria are usually found in decomposing plants and

lactic products. Lactic acid is the major metabolic end-product of the carbohydrate

fermentation. LAB is a large group of fermentative, anaerobe aero-tolerant

microorganisms that are usually present in the gut of humans and other animals,

raw vegetables, meat and meat products, and cereal.

Study Design: Samples were obtained directly from the 72-hour fermenting mash

of the kun-uzaki made from each cereal type. The Pour plate technique was used

to isolate the organisms. The pure colonies isolates were examined according to

their colony morphology, catalase reaction and gram reaction. Inhibition of

indicator lawn used ≥10mm inhibition as antibiotic susceptible. Adhesion was

measured by staining and quantifying grains of Digitariaexilis (acha), Sorghum

bicolour (sorghum) and Pennisetum americanum (millet) in composite and non

composite proportions. LAB isolates were obtained on MRS agar. Homo

fermenting isolates were identified at species level using the API 50 CHL test kit.

Antibiotic sensitivity testing on the identified isolates followed the modified

standard Kirby-Bauer procedure on MRS agar (pH 7.4) using the disc diffusion

technique with selected antibiotics. For quality control of the antibiotics, sensitive

reference strains S. aureus ATCC 25923 and E. coli ATCC 25922 obtained from

the Nigeria Institute of Medical Research were used. Adhesion properties were

determined by differential staining of the bacterial cells that bound to intestinal

epithelial cells as observed under light and phase contrast microscopy. 

Results: Antimicrobial substances produced by the eight LAB isolates inhibited

the growth of four selected human pathogens in vitro. All eight LAB isolates were

resistant to amoxicillin, gentamycin and ciprofloxacin. L. plantarum126, L.

paracasei sub sp paracasei339 and Pediococcus damnosus32 were resistant to

erythromycin whilst all others were susceptible. L. plantarum126 and L.

paracaseisubspparacasei339 were resistant to all antibiotics tested. All LAB

isolates demonstrated high in-vitro intestinal epithelial cell adhesion potential. The

result of this study documents findings on the antibiotic resistance pattern of these

eight homo-fermenting lactic acid bacteria present in ready to drink kunu-zaki. If

these homo-fermenting strains are to be used in kunu-zaki as starter cultures, it is

important that they should be further carefully examined for inability to transfer

antibiotic resistance genes to food pathogens.

Conclusion: When used in conjunction with these antibiotic treatments, kunuzaki

may not have an impact on the antibacterial activity of LAB. To ensure that these

LAB strains cannot pass antibiotic resistance genes to food pathogens, they must

Synthesis and Characterization of Transition Metal(II) Complexes Derived from (E)-N-(4-Methylbenzylidene)-2-((Z)-(4-Methylbenzylidene) Amino)Benzamides: Investigation of Biological Activities | Chapter 10 | Recent Developments in Chemistry and Biochemistry Research Vol. 3

We synthesized a novel series of transition metal(II) complexes 5a-h by reacting key transition metals (Co, Cu, Zn, Ni) with the Schiff base 3, derived from (E)-N-(4-methylbenzylidene)-2-((Z)-(4-methylbenzylidene)amino)benzamide. Schiff base 3 was previously prepared by reacting 2-aminobenzohydrazide 1 with 4-methylbenzaldehyde 2. The structures of the metal complexes were characterized using IR, NMR, mass spectrometry, and elemental analysis. We evaluated the synthesized metal complexes for antioxidant, antimicrobial, and antifungal activities. Notably, compounds 5e and 5c exhibited enhanced antimicrobial activity compared to the free ligand. Compounds 5g and 5a showed significant activity against various bacterial strains. Additionally, the hydrated metal complexes 5b, 5d, 5f, and 5h demonstrated moderate to good antimicrobial activity. In terms of antioxidant activity, most of the metal complexes displayed moderate to good activity comparable to ascorbic acid. Our bioassay results highlighted compounds 5e and 5c as effective antimicrobial agents against highly resistant microbial strains.

Drug Repurposing of Pharmaceutical Products and Antimicrobial Discovery | Chapter 2 | Advanced Concepts in Pharmaceutical Research Vol. 7

The process of identifying new therapeutic uses for existing medications is known as drug repurposing. It's a good way to find or develop new drug compounds with different pharmacological applications. In recent years, numerous pharmaceutical companies have used the drug reformulation technique in their Research and Development of pharmaceuticals programmes to produce new medications based on the identification of new biological drug targets. This technique is extremely efficient, saves time, minimal cost, and has a low risk of failure. It boosts a drug's therapeutic value and its success rate. As a result, drug repositioning is a viable alternative to the standard drug development procedure. Identifying novel molecular compounds by de novo approach of drug is challenging, tedious and costly endeavor. To identify novel use of drug molecules many laboratory and drug interactions is been done. It is thus thought to be a developing method in existing drug, which have previously been shown safe in people and are in turn used to tackle rare and complicated diseases. Biopharmaceutical businesses have struggled to get the anticipated results when aiming to boost productivity through novel discovery technologies. Repositioning existing medications for new indications could help the industry achieve productivity gains. More firms are looking for repositioning options in their existing pharmacopoeia, and the number of drug repurposing has many success stories.

Integration of Acetamide Single Crystal Growth Dynamics, Characterisation, NLO, and Antibacterial Properties by Oxalic Acid through Shock Wave Treatment | Chapter 13 | Novel Aspects on Chemistry and Biochemistry Vol. 8

 The ocular and surface morphological traits of the acetamide-doped oxalic acid (OXAC) single clear were systematically resolved for varying numbers of shock pulses (0, 1, 3, 5, and 7) while asserting a constant Mach number of 1.7 so that investigate the impact of shock waves on the material. The slow evaporation design was used to create the test clear of OXAC. The optical microscope and UV–seeable spectrometer were used to examine the surface semantic and optical characteristics, individually. Shock waves are used on non-uninterrupted optical matters because of their extreme nonlinear efficiency and quick backlash in electro-optic switches, exceptionally for organic matters. Among other transparent growth methods, the slow dissolution method has existed used to generate an acetamide-drugged oxalic acid single transparent at room temperature. Single clear oxac applies to shock waves in steps of 50 and 100 shock waves to the tail or the material properties outside altering the original transparent system. The mature and shock wave treated crystal of OXAC were structurally identified by X-ray dissemination and Fourier transform color of blood spectroscopy, UV-Visible and Photoluminescence spectral study, nonlinear optical activity (NLO) studies. Significant changes engaged of applied shock forces to matters. Optical absorption is a notable change when shock is raised, and it is due to the augmentation of the structural order of the materials, that may have happen due to hydrogen bonds. Antimicrobial hearings were conducted, containing a discussion of the findings from the completely clean and antifungal activity of the caused crystals of oxalic acid, OXAC, and OXAC accompanying 50 and 100 shocks. Our results indicate that the possessions of NLO are being enhanced by the post-sudden strong wave generated OXAC clear, which is still evident in fundamental and optical investigations and antimicroibial studies concerning the pre-shock wave caused OXAC crystal.

Antimicrobial Cytidine Derivatives as Anticancer Agents with in Silico Studies | Chapter 9 | Novel Aspects on Chemistry and Biochemistry Vol. 7

 The present study focuses on the computational inquiry of the antibacterial, anticancer, and construction-activity connection (SAR) properties of cytidine and allure analogs. Nucleosides are glycosylamines that can be thinking of as nucleotides without a phosphate group. A nucleoside exists simply of a nucleobase (more termed a nitrogenous base) and a five-element sugar (ribose or 2'-deoxyribose) when in fact a nucleotide is composed of a nucleobase, a five-element sugar, and individual or more phosphate groups. In a nucleoside, the anomeric carbon is connected through a glycosidic bond to the N9 of a purine or the N1 of a pyrimidine. Nucleotides are the microscopic building blocks of DNA and RNA. Nucleoside analogs have a meaningful role in the drug and clinical areas as therapeutic powers and authorized pharmaceuticals. Microdilution persistent the modified analogs' completely clean activity, MIC, and MBC against human and phytopathogenic isolates. Compounds (7), (10), and (14) were ultimate potent against Escherichia coli and Salmonella abony strains, accompanying MIC and MBC values from 0.316 ± 0.02 to 2.50 ± 0.03 and 0.625 ± 0.04 to 5.01 ± 0.06 mg/ml, individually. The highest inhibitory venture was observed against grandam-positive microorganisms. Numerous analogs (10), (13), (14), and (15) exhibited good venture against the tested fungi Aspergillus niger and Aspergillus flavus. The anticancer project of the cytidine analogs was examined through an MTT colorimetric assay against Ehrlich’s ascites malignant growth (EAC) tumor containers, whereas compound 6 granted the maximum antiproliferative activity accompanying an IC50 value of 1168.97 µg/ml.
