AZD9977 是一种有效的，选择性的，具有口服活性的盐皮质激素受体 (MR) 调节剂。AZD9977 用于心力衰竭和慢性肾病的研究。
AZD9977 is a potent, selective, and orally active mineralocorticoid receptor (MR) modulator. AZD9977 is used for heart failure, and chronic kidney disease research[1].
AZD9977 and eplerenone activities on MR, GR, PR and AR in binding assays. The observed pKi of MR, GR, and PR are 7.5, 5.4 and 4.6, respectively.Functional interaction of AZD9977 with MR is characterized in a reporter gene assay where the full-length MR drives a luciferase reporter gene in U2-OS cells. AZD9977 antagonizes aldosterone-activated MR with an IC50 of 0.28 μM. Whereas eplerenone is a full antagonist, AZD9977 suppresses only 69% of the MR activity in this assay.Species selective potencies of AZD9977 are established in reporter gene assays using the MR LBDs from human, mouse or rat. The corresponding IC50 values are 0.37 μM, 0.08 μM and 0.08μM, respectively.
AZD9977 (oral administration; 10-100 mg/kg; 4 weeks) dose dependently reduces the UACR compared to vehicle in uni-nephrectomised male Sprague Dawley rats administered aldosterone and fed a high-salt diet. AZD9977 is as efficacious as full MR antagonists on renal protection, despite the partial antagonism observed in in vitro assays[1].AZD9977 (oral administration; 100 mg/kg; co-administration with enalapril) stops further disease progression and reduces the urine albumin excretion (UAE) compared to vehicle treatment. Co-administration of enalapril has an apparent additive effect on UAE reduction, although this reduction is not statistically significant[1].
