was observed in preclinical models of phototoxicity. Herein, we describe a preclinical phototoxicity mitigation strategy for diarylamine containing molecules utilizing the introduction of an amide or suitable heterocyclic function. This strategy led to the development of two second-generation compounds with low risk of phototoxicity, disparate exposure profiles, and comparable efficacy to 1 in a rodent
研究显示,二酰基甘油O-酰基转移酶1(DGAT1)抑制剂Pradigastat(1)可有效降低家族性乳糜微粒血症综合征(FCS)患者的餐后甘油三酯水平。尽管在40 mg的高临床剂量下,普拉格达司他不会引起人的光敏性,但在临床前光毒性模型中观察到阳性信号。在本文中,我们描述了利用酰胺或合适的杂环功能引入的含二芳基胺的分子的临床前光毒性缓解策略。该策略导致开发出两种第二代化合物,这些化合物具有低的光毒性风险,不同的暴露特征以及与1相当的功效。 在餐后血浆甘油三酸酯的啮齿类动物脂质推注模型中。
