Trichostatin A (TSA) and suberoylanilide hydroxamic acid (SAHA) were reported in our recent publication as novel human high density lipoprotein (HDL) receptor CD36 and Lysosomal integral membrane protein-II Analogous-1 (CLA-1) up-regulators. As part of a broader effort to more fully explore the structure-activity relationships (SAR) of CLA-1 up-regulators, we synthesized a series of hydroxamic acid derivatives and evaluated their CLA-1 up-regulating activities in HepG2 cells. Some compounds exhibited over 10-fold up-regulation of CLA-1 expression in HepG2 cells at 10 μg/mL concentration. The compound 1g showed the best potency, with a lower EC50 than TSA (EC50 = 0.32 μM versus 1.2 μM). These compounds provide early new CLA-1 up-regulators with potential for treating atherosclerosis.
在我们最近的出版物中报道,三氟氯乙酰胺(TSA)和水杨酰胺羟肟酸(SAHA)被发现是新型的人类高密度脂蛋白(HDL)受体CD36和溶酶体整合膜蛋白-II类似物1(CLA-1)的上调剂。作为更全面探索CLA-1上调剂结构-活性关系(SAR)的一部分,我们合成了一系列羟肟酸衍生物,并在HepG2细胞中评估了它们的CLA-1上调活性。某些化合物在10 μg/mL浓度下表现出超过10倍的CLA-1表达上调。化合物1g展现出最佳效力,其EC50低于TSA(EC50 = 0.32 μM对比1.2 μM)。这些化合物提供了早期的新CLA-1上调剂,具有治疗动脉粥样硬化的潜力。
