Structure based design led directly to 1,3-oxazinan-2-one 9a with an IC50 of 42 nM against 11β-HSD1 in vitro. Optimization of 9a for improved in vitro enzymatic and cellular potency afforded 25f with IC50 values of 0.8 nM for the enzyme and 2.5 nM in adipocytes. In addition, 25f has 94% oral bioavailability in rat and >1000× selectivity over 11β-HSD2. In mice, 25f was distributed to the target tissues
基于结构的设计直接导致了1,3-恶二酮-2-酮9a在体外对11β-HSD1的IC 50为42 nM。优化9a以提高体外酶和细胞效能可得到25f,其酶的IC 50值为0.8 nM,而在脂肪细胞中的IC 50值为2.5 nM。另外,25f在大鼠中具有94%的口服生物利用度,并且相对于11β-HSD2具有> 1000倍的选择性。在小鼠中,将25f分配至靶组织,肝脏和脂肪,在食蟹猴中,口服10 mg / kg剂量的可的松攻击后,皮质醇的产生减少了85%。
