AZD7545 是一种有效，竞争性和选择性的 PDHK2 抑制剂，对 PDHK1 和 PDHK2 的 IC50 分别为 36.8 nM 和 6.4 nM。 Information AZD7545 AZD7545 is a potent PDHK inhibitor with IC50 of 36.8 nM and 6.4 nM for PDHK1 and PDHK2 , respectively. It failed to inhibit PDHK4 at higher concentrations(>10 nM), AZD7545 stimulates PDHK4 activity. Targets PDHK2 ; PDHK1 6.4 nM; 36.8 nM In vitro In the presence of recombinant human PDHK2, AZD7545 increases PDH activity with EC50 of 5.2 nM. In primary rat hepatocytes, AZD7545 increases PDH activity with EC50 of 105 nM. AZD7545 inhibits PDHK activity by disrupting the interactions between PDHK2 and the inner lipoyl-bearing domains (L2) of the dihydrolipoyl transacetylase component (E2) of PDC. In vivo In Wistar rats, AZD7545 increases the percentage of active PDH in the liver and skeletal muscle. In obese, insulin-resistant, Zucker rats, AZD7545 eliminates the postprandial elevation in blood glucose.
