Antimicrobial and Hypoglycemic Activities of Novel N-Mannich Bases Derived from 5-(1-Adamantyl)-4-substituted-1,2,4-triazoline-3-thiones
The reaction of 5-(1-adamantyl)-4-ethyl or allyl-1,2,4-triazoline-3-thione with formaldehyde solution and various 1-substituted piperazines yielded the corresponding N-Mannich bases. The newly synthesized N-Mannich bases were tested for in vitro inhibitory activities against a panel of Gram-positive and Gram-negative bacteria and the yeast-like pathogenic fungus Candida albicans. Six compounds ...
متن کاملSynthesis of substituted 5-(1,2,4-oxadiazol-5-yl)-3,4-dihydropyrimidine-2(1H)-thiones.
We have developed a liquid-phase route for combinatorial synthesis of novel substituted 5-(1,2,4-oxadiazol-5-yl)-3,4-dihydropyrimidine-2(1H)-thiones. Biginelli-type three-component condensation of 1-(3-aryl-1,2,4-oxadiazol-5-yl)acetones, thiourea, and benzaldehydes is shown to result in new 5-(1,2,4-oxadiazol-5-yl)-3,4-dihydropyrimidine-2(1H)-thione heterocyclic system. If salicylaldehydes are ...
متن کاملSyntheses and crystal structures of two adamantyl-substituted 1,2,4-triazole-5-thione N-Mannich bases
In the title N-Mannich bases, 3-(adamantan-1-yl)-4-(4-fluoro-phen-yl)-1-[(4-phenyl-piperazin-1-yl)meth-yl]-4,5-di-hydro-1H-1,2,4-triazole-5-thione (C29H34FN5S) (I), and 3-(adamantan-1-yl)-4-(4-fluoro-phen-yl)-1-{[4-(2-meth-oxyphen-yl)piperazin-1-yl]-meth-yl}-4,5-di-hydro-1H-1,2,4-triazole-5-thione (C30H36FN5OS) (II), fluoro-phenyl, adamantane and piperazine moieties are linked to a planar triaz...
متن کاملSynthesis and Biological Activity of Certain Mannich Bases Derivatives from 1, 2, 4-Triazoles
Substituted 1, 2, 4- Triazoles have shown multiple biological activities such as anti-inflammatory, anti fungal, etc. 5-mercapto triazoles were prepared from the potassium dithiocarbazinates. These triazoles were used for preparation of different derivatives by two different schemes. In the first scheme the Mannich bases were prepared from 5- marcapto-s triazole Quinazolines. The 5-Marcato-s-Tr...
متن کاملNovel 1,3,4-(thiadiazol-2-ylamino) methyl-5-(pyridin-4-yl)-1,3,4-oxadiazol-2-thiones: synthesis, docking and antimycobacterial testing
In the present study, a novel series of Mannich bases of 3-substituted 5-(pyridin-4-yl)-1,3, 4-oxadiazol-2-thione derivatives were synthesized. Docking study was performed to rationalize the possible interactions between the synthesized compounds and active site of 14DM. The test compounds were screened for antimycobacterial activity using Middlebrook 7H9 medium against M. tuberculosis H37Rv (A...
