5 μM respectively. Compound 8v is a competitive inhibitor with respect to pyruvate (Ki = 0.74 μM) and a mixed-type inhibitor with respect to ATP, indicating that it targets the unique carboxyltransferase (CT) domain of PC. Furthermore, compound 8v does not significantly inhibit human carbonic anhydrase II, matrix metalloproteinase-2, malate dehydrogenase or lactate dehydrogenase.
通过基于结构的药物设计项目(SBDD),发现了有效的丙酮酸羧化酶小分子抑制剂(PC)。制备了一系列α-酮酸(7)和α-羟基肉桂酸(8),并在两种测定中评估了其对PC的抑制作用。两种最有效的抑制剂是3,3'-(1,4-亚苯基)双[2-羟基-2-丙酸](8u)和2-羟基-3-(喹啉-2-基)丙酸(8v))的IC 50值分别为3.0±1.0μM和4.3±1.5μM。化合物8v是相对于丙酮酸(K i = 0.74μM)和针对ATP的混合型抑制剂,表明它靶向PC的独特羧基转移酶(CT)域。此外,化合物8v不会显着抑制人碳酸酐酶II,基质金属蛋白酶-2,苹果酸脱氢酶或乳酸脱氢酶。
