Dihydropyrazole and 1,3,4-Thiadizole derivatives are an attractive class of biologically active heterocyclic compounds. An efficient procedure for the synthesis of Novel 2-(5-(4-bromophenyl)-3-(4-fluorophenyl)-4,5-dihydropyrazol-1-yl)-N-(5-(3 hydroxyphenyl)-1,3,4-thiadiazol-2-yl)acetamidevia one-pot threecomponent condensation of 2-hydrazinyl-N-(4-subsituted phenyl thiadiazol -2-yl) with aromatic aldehydes and substituted acetophenones is described. The structures of synthesized compounds were confirmed by analytical and spectroscopic methods including, infrared, nuclear magnetic resonance and mass spectroscopy. This protocol has advantages of mild conditions, high yield, and simple workup procedure. All the synthesized compounds were tested for their in-vitro growth inhibitory activity against a panel of standard strains of pathogenic microorganism including M. tuberculosis (H37Rv) and Gram positive bacteria (Staphylococcus aures, Bacillus subtilis and Bacilluscerus), Gram negative bacteria (Escherichia coli, Proteus vulgaris, and Pseudomonas aeruginosa) and fungal strains (Aspergillus, A. fumigates and C. albicans). Their antitubercular, antimicrobial activity study revealed that all the compounds tested showed moderate to good antitubercular, antibacterial and antifungal activity.
