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 EC(50) than TSA (EC(50) = 0.32 μM versus 1.2 μM). These compounds provide early new CLA-1 up-regulators with potential for treating atherosclerosis.
我们在最近的出版物中报道,三氮唑酮 A(TSA)和琥珀酰亚胺基羟肟酸(SAHA)是新型的人高密度脂蛋白(HDL)受体 CD36 和溶酶体整合膜蛋白-II 类似物-1(CLA-1)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 细胞中评估了它们对 CLA-1 的上调活性。一些化合物在 10μg/mL 浓度下使 HepG2 细胞中 CLA-1 的表达上调了 10 多倍。化合物 1g 表现出最好的活性,其 EC50低于 TSA(EC50=0.32μM 对 1.2μM)。这些化合物提供了具有治疗动脉粥样硬化潜力的新型 CLA-1 上调剂。
