Tuberculosis (TB) ranks second, next to AIDS making it most formidable disease if the present age. One of the crucial enzymes involved in cell wall synthesis of Mycobacterium tuberculosis, InhA (enoyl acyl carrier protein reductase) has been authenticated as an effective target for anti-mycobacterial drug development. In the current work, we have developed novel derivatives of 1,2,4-triazole-5-...

Novel 3-(3-benzyl-2,3-dihydrobenzo[ d]thiazol-2-yl)benzo[ d]oxazole-2(3 H)-thione derivatives are efficiently synthesized in excellent yields by reactions of benzothiazoles, benzyl bromides, and 2-mercaptobenzoxazole acetone under catalyst-free conditions the presence triethylamine. The structures products confirmed nuclear magnetic resonance spectroscopy, infrared electron ionization mass spec...

the reaction of readily available 1 -methyl-4-nitropyrrole-2- carboxylic acid (1) with thionyl chloride afforded the corresponding acyl chloride 2. the reaction of compound 2 with thiosemicarbazides yielded 1-(1 -methyl-4-nitrop yrrole-2-carbony1)- thiosemicarbazides (3) which cyclized in basic medium to 5-(1-methyl-4-nitropyrrole- 2-y1)-2,4-dihydro-3h- l,2,4-triazole-3- thione 4. alkylation an...

The title compound, C(25)H(35)N(5)OS, is a functionalized triazoline-3-thione with substituted piperazine and adamantyl substituents attached at the 2- and 5-positions, respectively, of a triazole spacer with an approximately C-shaped conformation of the mol-ecule. The piperazine ring adopts a chair conformation.

Alkylated, benzylated and bromoalkylated benzimidazole-thione that intramolecularly heterocyclized to 3,4-dihydro-2H-[1,3]thiazino[3,2-a]benzimidazole were synthesized. The chemical structure of the synthesized product was characterized by Infra Red, ¹H-NMR, (13)C-NMR, and Mass spectroscopy. Furthermore, the molecular structures of 8 and 9 were confirmed by X-ray single crystallography in diffe...

The title compound C(7)H(5)N(3)S(2), occurs as the thione tautomer in the solid state; the dihedral angle between the pyridine and thia-diazole ring planes is 2.08 (6)°. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, generating C(8) chains propagating in [010].

The title compound, C15H13ClN2O2S, exists in the solid state in its thione form with typical thio-urea C-S and C-O bonds lengths as well as shortened C-N bonds. An intra-molecular N-H⋯O hydrogen bond stabilizes the mol-ecular conformation. In the crystal, N-H⋯S hydrogen bonds link the mol-ecules into centrosymmetric dimers.

In the title compound, C(14)H(10)BrN(5)S, the dihedral angle between the triazole ring and the pyridine and bromo-benzene rings are 26.42 (13) and 6.28 (13)°, respectively. The molecule exists as a thione in the solid state. In the crystal, mol-ecules are linked by N-H⋯N hydrogen bonds, generating [010] C(8) chains.
