derivatives as potent and highly selective SMS2 inhibitors through a conformational restriction strategy. After systematic structural modifications, several compounds with high selectivity and good potency in vitro were selected for further evaluation. Compound 15w demonstrated good pharmacokinetics (oral bioavailability, F = 56%) in vivo and has an inhibitory potency against sphingomyelin synthase activity
鞘磷脂合成酶2(SMS2)是几种慢性炎症相关疾病(包括动脉粥样硬化,脂肪肝和胰岛素抵抗)的有希望的治疗靶标。在这里,我们报告通过构象限制策略鉴定4-苄氧基苯并[ d ]异恶唑-3-胺衍生物作为有效和高度选择性的SMS2抑制剂。经过系统的结构修饰后,选择了几种具有高选择性和良好体外效能的化合物进行进一步评估。化合物15w在体内表现出良好的药代动力学(口服生物利用度,F = 56%)当向癌症研究所的小鼠提供口服剂量的该化合物时,它对鞘磷脂合成酶的活性具有抑制作用。另外,在口服给药6周后,化合物15w在db / db小鼠中显着减轻了慢性炎症。
