A Mini Review: Biological Significances of Nitrogen Hetero Atom Containing Heterocyclic Compounds

Heterocycles have vital interest in the pharmaceuticals and agrochemicals. Synthetic chemistry provides wealth of heterocyclic systems. More than 90% of drugs contain heterocycles ring and the interface between chemistry and biology. Scientific insight, discovery and applications are taking place by heterocyclic compounds. This review article covers theactive heterocycles that have shown consid...

Nitrogen starvation promotes biodegradation of N-heterocyclic compounds in soil

Mineralization studies were performed to examine the impact of N deprivation on microbial utilization of the N-heterocyclic herbicides, atrazine and cloransulam-methyl (C-M). Soil depleted by 130 years of cropping to Zea mays without fertilization was contrasted to soil from the same site regularly receiving fertilizers. Long-term N deprivation promoted rapid degradation of atrazine and the C-M...

ORGANIC CHEMISTRY Organic Compounds containing Nitrogen

Synthesis and analysis of some bis-heterocyclic compounds containing sulphur.

A facile and convenient synthesis of a series of bisheterocycles 7a,b 10, 12 and 13a,b containing a thieno[2,3-b]thiophene base unit via the versatile, hitherto unreported 3-[3,4-dimethyl-5-(3-nitrilopropanoyl)thieno[2,3-b]thiophen-2-yl]-3-oxopropanenitrile (4) is described.

Electrochemical activities of some heterocyclic compounds containing benzimidazole moiety

A number of N-substituted benzimidazole derivatives have been synthesized and tested for their antibacterial activities. The chemical structures of the newly synthesized compounds were verified on the basis of spectral and elemental methods of analysis. Apart of this electrochemical analysis are performed on these derivatives. The electrochemical reduction of these compounds takes place in a si...
