A series of novel 5-phenyl-substituted 1,3,4-thiadiazole-2-amines were designed, synthesized, and screened for their antitumor and antitubercular activities. The target compounds were synthesized starting from isocyanates and acid hydrazides by convention

Due to the increasing microbial resistance to antibacterial and antifungal drugs, the development of new antimicrobial agents is an urgent priority. In search of newer antimicrobial agents, a series of 4,5-disubstituted-3-mercapto-1,2,4-triazole derivatives were synthesized from aromatic acids and substituted isothiocyanates. The in silico study was performed to study the binding interactions of the synthesized compounds with the active pocket of CYP51. Among the synthesized 3-mercapto-triazole derivatives, compounds 6r, 6s and 6u exhibited promising antimicrobial activity comparable to standard drugs. The results suggested that the structural modification to 3-mercapto-1,2,4-triazole derivatives could lead to promising antimicrobial scaffolds.

We report herein the discovery of 3,5-dinitrophenyl 1,2,4-triazoles with excellent and selective antimycobacterial activities against Mycobacterium tuberculosis strains, including clinically isolated multidrug-resistant strains. Thorough structure-activity relationship studies of 3,5-dinitrophenyl-containing 1,2,4-triazoles and their trifluoromethyl analogues revealed the key role of the position of the 3,5-dinitrophenyl fragment in the antitubercular efficiency. Among the prepared compounds, the highest in vitro antimycobacterial activities against M. tuberculosis H37Rv and against seven clinically isolated multidrug-resistant strains of M. tuberculosis were found with S-substituted 4-alkyl-5-(3,5-dinitrophenyl)-4H-1,2,4-triazole-3-thiols and their 3-nitro-5-(trifluoromethyl)phenyl analogues. The minimum inhibitory concentrations of these compounds reached 0.03 μM, which is superior to all the current first-line anti-tuberculosis drugs. Furthermore, almost all compounds with excellent antimycobacterial activities exhibited very low in vitro cytotoxicities against two proliferating mammalian cell lines. The docking study indicated that these compounds acted as the inhibitors of decaprenylphosphoryl-β-d-ribofuranose 2′-oxidase enzyme, which was experimentally confirmed by two independent radiolabeling experiments.

Abstract Reaction of hydrazides of 4-alkoxybenzoic acids with benzyl isothiocyanate followed by cyclization with thiosemicarbazide afforded a series of new 4,5-substituted 4H-1,2,4-triazole-3-thiols. S-Alkylation of the latter led to the formation of the
