GSK2945 hydrochloride 是一类叔胺,是一种高度特异性的Rev-erbα/REV-ERBα(小鼠/人反向成红细胞病病毒α) 拮抗剂, 其EC50值分别为 21.5 μM 和 20.8 μM。GSK2945 hydrochloride 可增强胆固醇 7α-羟化酶 (CYP7A1) 水平和胆固醇代谢。
生物活性 | GSK2945 hydrochloride is a class of tertiary amine, and is a highly specificRev-erbα/REV-ERBα (mouse/human reverse erythroblastosis virus α)antagonist withEC50s of 21.5 μM and 20.8 μM, respectively. GSK2945 hydrochloride enhancescholesterol7α-hydroxylase (CYP7A1)level andcholesterolmetabolism[1]. |
体外研究 (In Vitro) | GSK2945 dose-dependently enhances the transcriptional activity of Rev-erbα and a Bmal1 (a target gene of REV-ERBs) luciferase reporter (EC50of 2.05 μM)[1]. GSK2945 (20 μM; 12 hours and 24 hours; mouse and human primary hepatocytes) treatment increases levels of Cyp7a1/CYP7A1 in mouse and human primary hepatocytes. GSK2945 (20 μM) treatment also increases Lrh-1/LRH-1 (a known hepatic activator of Cyp7a1/CYP7A1) mRNA and protein[1].
RT-PCR[1] Cell Line: | Mouse (male, CD1) and human (male, Caucasian) primary hepatocytes | Concentration: | 20 μM | Incubation Time: | 12 hours and 24 hours | Result: | Led to significant increases in mRNA and protein (at 24-h) expression of Cyp7a1. mRNA and protein (at 24-h) levels of CYP7A1 were increased in human primary hepatocyte. Lrh-1/LRH-1 was upregulated. |

体内研究 (In Vivo) | GSK2945 (0-10 mg/kg; intraperitoneal injection; twice every day; for 7 days; male C57BL/6 mice) treatment increases hepatic mouse cholesterol 7α-hydroxylase (Cyp7a1) level and lowers plasma cholesterol in wild-type mice[1].
Animal Model: | Male C57BL/6 mice (8-10 weeks of age)[1] | Dosage: | 0 mg/kg or 10 mg/kg | Administration: | Intraperitoneal injection; twice every day; for 7 days | Result: | Increased hepatic mouse cholesterol 7α-hydroxylase (Cyp7a1) level and lowered plasma cholesterol in wild-type mice. |
