Pyrazoles are examined and very important fundamental analogues of chalcones and have very special place in synthetic curative due to allure pharmacological importance. Presence of pyrazole ring system in a lot of naturally happening molecules is one of the distinguishing characteristics concerning this heterocyclic system. Inspired by wonderful biological activity and fundamental complexity of pyrazole analogues we are occupied in area of chalcone and pyrazole synthesis. By reacting chalcone products with phenylhydrazine, a atheneum of novel dihydropyrazole compounds was created from well-designed Curcumin analogues. All the combined compounds were characterized by spectroscopic (1H and 13C NMR, IR ranges), spectrometric (Mass spectra) dossier and elemental analysis. Due to the occupancy of optically active element in the pyrazole ring, dihydropyrazoles exhibited the characteristic dd (double doublet). All of the combined compounds were tested for antifungal venture against six distinct fungal starins. With MIC (Minimum Inhibitory Concentration) values until 3.12µg/ml., evaluated heterocyles shown strong inhibitory features against the tested fungal strains. Antifungal activity was excellent in heterocyles containing nitro and methoxy modifications. SAR has existed created between the many substitutions at the phenyl ring of produced heterocycles with 20 distinct derivatives determined for biological venture.
