report describes the design, synthesis and pharmacological characterization of a series of 6,7-dimethoxyquinazoline derivatives having beta-arylethylamine substituents at the 2- or 4-positions. The quinazoline nucleus is intended to confer a high degree of inhibitory activity for phosphodiesterase while the beta-aryethylamine moieties are designed to provide selectivity for adrenergically innervated tissue
具有不同动力学特性的几种形式的cAMP磷酸二酯酶的存在表明开发这种酶的组织选择性抑制剂的可行性。该观察在开发用于治疗可逆性阻塞性气道疾病的治疗剂中特别重要。本报告描述了一系列在2或4位具有β-芳基乙胺取代基的6,7-二甲氧基喹唑啉衍生物的设计,合成和药理学表征。喹唑啉核旨在赋予磷酸二酯酶高度的抑制活性,而β-芳基乙胺部分则旨在为肾上腺素能神经支配的组织提供选择性。本研究的目标化合物6和7 通过从适当的氯喹唑啉中间体取代氯的β-芳基乙胺制备氯乙烯。评价所得产物松弛豚鼠气管平滑肌和作为磷酸二酯酶抑制剂的能力。
