anti-inflammatory activities for treatment of acute lung injury (ALI). There were 29 compounds designed, prepared, and subjected to PI3Kδ inhibitory activity evaluation and anti-inflammatory activity evaluation in macrophages. (S)-29 was identified as a candidate with high PI3Kδ inhibitory activity, isoform selectivity, and high oral bioavailability. The in vivo administration of (S)-29 at 10 mg/kg dosage could
PI3Kδ是治疗炎症性疾病的一个有前景的靶点;然而,PI3Kδ抑制剂在急性呼吸道炎症性疾病中的应用却鲜有研究。在本研究中,通过支架跳跃设计,我们报告了一系列新的 1 H -吡唑并[3,4- d ]嘧啶-4-胺系链 3-甲基-1-芳基-1 H -吲唑,具有高选择性和有效的特性PI3Kδ 抑制剂具有显着的抗炎活性,可用于治疗急性肺损伤(ALI)。设计、制备了29种化合物,并在巨噬细胞中进行了PI3Kδ抑制活性评价和抗炎活性评价。 ( S )-29被确定为具有高 PI3Kδ 抑制活性、亚型选择性和高口服生物利用度的候选药物。体内施用10 mg/kg剂量的( S )-29可以显着改善LPS攻击小鼠肺组织的组织病理学变化并减轻肺部炎症。分子对接证明了支架跳跃设计的成功。总体而言, ( S )-29是一种有效的 PI3Kδ 抑制剂,可能是治疗 ALI 的有希望的候选药物。
