A series of pyrido[3′,2′:4,5]thieno[3,2-d]pyrimidines (PTP) has been synthesized and tested as phosphodiesterase IV inhibitors (PDE4), a target for the treatment of asthma and chronic obstructive pulmonary disease (COPD). Structure−activity relationships within this series, leading to an increase of potency on the enzyme, are presented. The gem-dimethylcycloalkyl moiety fused to the pyridine ring proved
合成了一系列吡啶并[3',2':4,5]噻吩并[3,2- d ]嘧啶(PTP)并作为磷酸二酯酶IV抑制剂(PDE4)进行了测试,这是治疗哮喘和慢性阻塞性疾病的靶标肺部疾病(COPD)。介绍了该系列中的结构活性关系,从而导致了酶效力的提高。为了在酶中获得更高的亲和力,与吡啶环稠合的宝石-二甲基环烷基被证明是支架的关键元素。
