In-vitro studies of two 5-nitroimidazole derivatives

In-vitro studies of two 5-nitroimidazole derivatives.

This paper reports the findings obtained using two new compounds belonging to the 5-nitroimidazole family: sulphuridazole (V1) and sulphonidazole (V2). We first assessed their antimicrobial activity on Clostridia spp. and then extended the study to Gram-positive and Gram-negative aerobic microorganisms and to Candida albicans. Their MICs were compared with those of metronidazole. The findings s...

synthesis and characterizing radiosensitizing effect of nitroimidazole derivatives and 5-fu in hypoxic ht-29 cell

Two different modes of halogen bonding in two 4-nitroimidazole derivatives.

In the crystal structures of the two imidazole derivatives 5-chloro-1,2-dimethyl-4-nitro-1H-imidazole, C(5)H(6)ClN(3)O(2), (I), and 2-chloro-1-methyl-4-nitro-1H-imidazole, C(4)H(4)ClN(3)O(2), (II), C-Cl...O halogen bonds are the principal specific interactions responsible for the crystal packing. Two different halogen-bond modes are observed: in (I), there is one very short and directional C-Cl...

synthesis of platinum nanostructures in two phase system

چکیده پلاتین، فلزی نجیب، پایدار و گران قیمت با خاصیت کاتالیزوری زیاد است که کاربرد های صنعتی فراوانی دارد. کمپلکس های پلاتین(ii) به عنوان دارو های ضد سرطان شناخته شدند و در شیمی درمانی بیماران سرطانی کاربرد دارند. خاصیت کاتالیزوری و عملکرد گزینشی پلاتین مستقیماً به اندازه و- شکل ماده ی پلاتینی بستگی دارد. بعضی از نانو ذرات فلزی در سطح مشترک مایع- مایع سنتز شده اند، اما نانو ساختار های پلاتین ب...

Synthesis and Biological Activity of Some New 5-Sulphanyl- 4-nitroimidazole Derivatives

A series of 5-sulphanyl derivatives of 1-Benzyl-2-alkyl-4-nitro-1H-imidazoles (5-9) were prepared by the coupling method of 3-(1-Benzyl-2-ethyl-4-nitro-1H-imidazole-5ylsulfanyl)propanoic acid (4) with appropriate amino acid ester hydrochloride, in the presence of hydroxybenzotriazole (HOBT) and DCC. Compounds (10-12) and (13) were similarly synthesized using appropriate amino alcohols, and 1-su...
