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...
متن کاملCytotoxic Effect of Some 1, 4-Dihydropyridine Derivatives Containing Nitroimidazole Moiety
The 1,4-dihydropyridine (DHP) derivatives are a known class of calcium channel blockers. Some derivatives of DHP showed significant cytotoxicity. It was shown that this effect may not be the result of interaction with Ca2+ channels. In this study, we performed an investigation about the intrinsic cytotoxicity of some derivatives of DHP containing nitroimidazole moiety on their C4 position on fo...

متن کاملSynthesis 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...
