A series of 4-anilinopyrazolopyridine derivatives were synthesized and biologically evaluated as inhibitors of phosphodiesterase (PDE4). Chemical modification of 3, a structurally new chemical lead that was found in our in-house library, was focused on 1- and 3-substituents. Full details of the discovery of a new orally active chemical lead 5 are presented. Structure–activity relationship data, pharmacological evaluation, and the subtype selectivity study are also presented.
合成了一系列4-氨基吡唑并吡啶衍生物,并对其作为磷酸二酯酶(PDE4)抑制剂进行生物评估。对3这一我们内部库中发现的结构新颖的化学先导物的化学改造主要集中在1-和3-取代基上。本文详细介绍了新型口服活性化学先导物5的发现,以及结构-活性关系数据、药理评估和亚型选择性研究的结果。
