Influence of 2-Substituent on the Activity of Imidazo[1,2-a] Pyridine Derivatives Against Human Cytomegalovirus
摘要:
The synthesis of various 2-substituted imidazo[1,2-a]pyridine bearing a thioether side chain in position 3 was reported. The new compounds were characterized by H-1 and C-13 NMR spectra. A conformational study was obtained by X-ray crystallographic analysis for 2-biphen-4-ylimidazopyridine 7. The antiviral activity against human cytomegalovirus (HCMV) was investigated. It was strongly influenced by the nature of C-2 substituent. (C) 2002 Elsevier Science Ltd. All rights reserved.
通过3-溴-1,1,1-三氟丙酮与各种杂芳基胺的反应合成了一系列具有咪唑环的杂环化合物,所述咪唑环与另一个带有桥头氮原子的环稠合并且带有三氟甲基部分。在某些情况下,分离出与所需产物一起获得的中间体化合物,并阐明其结构:例如,从2-氨基吡啶开始,我们获得了2-三氟甲基咪唑并[1,2-a]吡啶和2-羟基-2-三氟甲基-2,3-二氢-1 H-咪唑并[1,2- a ]溴化吡啶鎓。这样的结果证实了先前提出的用于该反应的机理。
