Nitroimidazoles. V. Synthesis and anti-HIV evaluation of new 5-substituted piperazinyl-4-nitroimidazole derivatives.
A series of 2-alkylthio-1-[4-(1-benzyl-2-ethyl-4-nitro-1H- -imidazol-5-yl)-piperazin-1-yl]ethanones (3-9) and alkyl-[4-(1-benzyl-2-ethyl-4-nitro-1H-imidazol-5-yl)-piperazin-1-yl)ketones (11-20) as well as the indole analogue 22 were synthesized from 4-nitro-5-piperazinyl imidazole derivative 1, with the aim to develop newly non-nucleoside reverse transcriptase inhibitors (NNRTIs). The newly syn...
متن کاملSynthesis and biological evaluation of new 4beta-5-Fu-substituted 4'-demethylepipodophyllotoxin derivatives.
A series of new 4beta-5-Fu-substituted 4'-demethylepipodophyllotoxin derivatives were synthesized and evaluated, together with some previously prepared ones, for their cytotoxic activities against four tumor cell lines (HL60, P388, A549 and BEL7402). Three of these compounds exhibited superior in vitro anticancer activity against P388 and A549 than the reference compound etoposide. In addition,...
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...
متن کاملSynthesis of 4- and 5- nitro-substituted heteroaryl cinnamoyl derivatives
In the condensation of the 4and 5-nitro-substituted 2-acetyl-1,3-indandione with heteroaryl aldehydes in the presence of alkaline or acidic catalysts, the corresponding cinnamoyl derivatives are obtained that possess anticoagulant activity, compared with that of 2-acetyl-1,3-indandione. It has been proven that some of the sodium salts of the cinnamoyl-indandione possess anticoagulant activity. ...
متن کاملTwo 1-substituted 4-nitroimidazoles.
Crystalline 4-nitro-1-phenylimidazole, C9H7N3O2, (I), and 4'-nitro-1-phenyl-4,1'-biiimidazole, C12H9N5O2, (II), contain C-H...O and C-H...N hydrogen bonds, connecting the molecules into infinite chains. The aromatic fragments in both compounds are nearly planar. The dihedral angles between the benzene and imidazole rings are 26.78 (5) degrees in (I) and 29.36 (8) degrees in (II).
