A novel series of potent C-6 substituted pyrazolo[1,5-a]pyridine inhibitors of herpes simplex viruses has been identified. A synthetic methodology was developed involving functionalization of a C-6 trifluoromethyl pyrazolo[1,5-a]pyridine to allow facile access to a diverse set of analogues from common late stage intermediates. The expansion of the SAR of this series at the 6 position allows for modifications
已经鉴定出一系列新的有效的单纯疱疹病毒的C-6取代的吡唑并[1,5-a]吡啶抑制剂。已开发出一种合成方法,其中涉及将C-6三氟甲基吡唑并[1,5-a]吡啶官能化,以便从常见的后期中间体轻松获得各种类似物。该系列SAR在6位的扩展使得可以修饰可开发性参数(例如clogP),同时保持与阿昔洛韦相当的效价。
