(MAPK) (MAPK14/11) inhibitors suitable for the treatment of pulmonary inflammatory conditions has been described. A rational drug design approach started from the identification of a novel tetrahydronaphthalene series, characterized by nanomolar inhibition of p38α with selectivity over p38γ and p38δ isoforms. SAR optimization of 1c is outlined, where improvements in potency against p38α and ligand–enzyme
已经描述了适用于治疗肺部炎症的新型吸入 p38α/β 丝裂原活化蛋白激酶 (MAPK) (MAPK14/11) 抑制剂的鉴定。合理的药物设计方法始于对新型四氢萘系列的鉴定,其特点是对 p38α 具有纳摩尔抑制作用,对 p38γ 和 p38δ 异构体具有选择性。概述了1c的SAR 优化,其中对 p38α 效力和配体-酶解离动力学的改进导致几种化合物在体外显示出明显的抗炎作用(抑制 TNFα 释放)。以确定的物理化学性质为目标,可以鉴定化合物3h、4e和4f,这表明,在细菌内毒素诱导的肺部炎症的大鼠急性模型中,气管内滴注后,血浆水平低、肺潴留时间延长和抗炎作用。尤其是化合物4e,显示出显着的功效和作用持续时间,并被选择用于哮喘和慢性阻塞性肺病 (COPD) 疾病模型的进展。
