TL;DR: N-(2,4-Dimethylphenyl)-5-(4-nitrophenyl)-1,3, 4-thiadiazol-2-amine (9h) showed excellent antioxidant activity more than the standard drug whereas 4,5-disubstituted-2,8-dihydro-3H-1,2-4-triazole-3-thione exhibited potent urease inhibitory activities.
Journal ArticleDOI
In vitro antitumor and antiviral activities of new benzothiazole and 1,3,4-oxadiazole-2-thione derivatives
TL;DR: The title compounds were tested against representatives of several virus families containing single stranded RNA genomes and against double-stranded RNA genomes, as well as some Flaviviridae viruses, and showed strong effects on leukaemia cell lines CCRF-CEM.
Journal ArticleDOI
Synthesis and anti‐HIV activity of new chiral 1,2,4‐triazoles and 1,3,4‐thiadiazoles
TL;DR: In this article, the authors used hydrazides with 4-chlorophenylisothiocyanate in MeOH to synthesize 4.5-substituted 4-(4-chlorophenylamino)-4H-1,2,4-triazol-3-thiones 3 and 2.
Journal ArticleDOI
Exploiting the Role of Molecular Electrostatic Potential, Deformation Density, Topology, and Energetics in the Characterization of S···N and Cl···N Supramolecular Motifs in Crystalline Triazolothiadiazoles
Imtiaz Khan,Piyush Panini,Salah Ud-Din Khan,Usman Ali Rana,Hina Andleeb,Deepak Chopra,Shahid Hameed,Jim Simpson +7 more
TL;DR: In this paper, a detailed analysis of the molecular and crystal packing of a series of pharmaceutically active triazolothiadiazole derivatives is reported, showing the presence of inversion dimers due to the formation of strong S···N chalcogen bonds.
Journal ArticleDOI
Design, synthesis, and urease inhibition studies of some 1,3,4-oxadiazoles and 1,2,4-triazoles derived from mandelic acid.
TL;DR: Some new structural type inhibitors of urease were synthesized in two steps from mandelic acid hydrazides and aryl isothiocyantes and may be subjected to further investigations for the development of antiulcer drugs.
