N-acylhydrazones (NAHs), the compound 8a was selected as a selective submicromolar phosphodiesterase-4 (PDE4) inhibitor associated with anti-TNF-α properties measured both in vitro and in vivo. The recognition pattern of compound 8a was elucidated through molecular modeling studies based on the knowledge of the 3D-structure of zardaverine, a PDE4 inhibitor resembling the structure of 8a, cocrystallized with
在一系列测试的N-酰基ac(NAHs)中,化合物8a被选为选择性的亚微摩尔磷酸二酯酶4(PDE4)抑制剂,与体外和体内的抗TNF-α特性相关。通过对分子模型研究阐明化合物8a的识别模式,该模型基于对zardaverine的3D结构的了解,zadaverine是一种类似于8a结构的PDE4抑制剂,与PDE4共结晶。基于对N-甲基-NAHs的进一步构象分析,喹唑啉衍生物(19)被设计为构象受限的NAH类似物,并且表现出相似的性质。体外药理学资料,与8a相比。另外,当在LPS诱发的气道高反应性中口服测试时,发现有19种有效,并且充分证实了支持这项工作的工作假设。
