discovery and structure-activity relationship of first-generation small-molecule malonyl-CoA decarboxylase (MCD; CoA = coenzyme A) inhibitors are reported. We demonstrated that MCD inhibitors increased malonyl-CoA concentration in the isolated working rat hearts. Malonyl-CoA is a potent, endogenous, and allosteric inhibitor of carnitine palmitoyltransferase-I (CPT-I), a key enzyme for mitochondrial fatty acid
报道了第一代小分子丙二酰辅酶A脱羧酶(MCD; CoA =辅酶A)抑制剂的发现及其与构效关系。我们证明了MCD抑制剂增加了离体大鼠心脏中丙二酰辅酶A的浓度。丙二酰辅酶A是一种有效的,内源性的,变构的肉碱棕榈酰转移酶-I(CPT-1)抑制剂,CPT-1是线粒体脂肪酸氧化的关键酶。由于丙二酰辅酶A水平的增加,脂肪酸氧化速率降低并且葡萄糖氧化速率显着提高。证明5-(N-(4-(1,1,1,3,3,3-六氟-2-羟基丙烷-2-基)苯基)吗啉-4-羧氨基ido)戊酸甲酯(6u)的体内功效)在猪缺血模型中表明MCD抑制剂可能对治疗缺血性心脏病有用。
