Studies on Sulfadoxine Interaction with Bovine Serum Albumin Using Spectral and Molecular Modeling | Chapter 5 | Current Perspectives on Chemical Sciences Vol. 7

The present research focuses on the binding interaction of sulfadoxine with bovine serum albumin using spectrofluorimetry under simulated physiological conditions. During the course of the research, various spectroscopic and other techniques such as Raman, CD, lifetime measurement and molecular modelling were also used. It was noticeable that the intrinsic fluorescence of BSA was quenched by sulfadoxine through static quenching. The spectral and docking studies explored the change in the secondary structure of the BSA and the binding mechanism.

Design, Synthesis of Sulfadiazine and Sulfisoxazole Guanidine Derivatives as Promising Anti-TB agents: An in-silico and in-vitro Approach | Chapter 3 | Current Perspectives on Chemical Sciences Vol. 5

 The physiologically active compounds of Guanidine display a number of activities such as antidiabetic, antimicrobial, antiviral, anticancer, antibiotic and anti-inflammatory, etc. The composition of imide urea is similar to guanidine, so the chemistry and properties of guanidine are similar to imide urea. Guanidine is one of the most attractive pharmacophores because of its broad range of pharmacological and biological activities. The presence of the -CN3 group in guanidine compounds allows them to have an important affinity for a wide variety of biochemical activities for different substituents. Novel Sulfadiazine/Sulfisoxazole guanidine derivatives were synthesised in the present study and characterised by spectral tests of FT-IR, LCMS and NMR. The synthesised compounds were screened for anti-TB activity and an InhA protein molecular docking analysis was performed. GLIDE calculated the molecule docking trials of ligands and proteins. The operation was ranked on the basis of the docking score. Compounds with electron donation groups were found to have exhibited superior behaviour.
