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.
