a10% hydroxylpropyl-β-cyclodextrin was used as vehicle. b0.5% methylcellulose and 1% Tween80 was used as vehicle. cDosed iv at 1 mg/kg, po at 5mg/kg. dDosed iv at 0.5 mg/kg, po at 4 mg/kg.Animal Model:ob/ob mice, diet-induced obesity (DIO) model
Dosage:20 mg/kg
Administration:Oral, once daily for 25 days
Result:Efficiently reduced postprandial glucose and/or blood HbA1c levels and suppressed hepatic mRNA levels of gluconeogenic enzymes. Clearly enhanced hepatic and whole-body insulin sensitivities in a hyperinsulinemic-euglycemic clamp experiment in DIO mice.
Animal Model:C57BL/6 mice, rats and dogs
Dosage:0.5 or 4 mg/kg
Administration:IV or PO (Pharmacokinetic Analysis)
Result:Showed good pharmacokinetic profiles.

体外研究:
SKI2852 在稳定转染人 11β-HSD1 cDNA 的 HEK293 细胞中抑制 11β-HSD1 的 IC50 为 4.4 ± 0.5 nM。SKI2852 的酰胺羰基与 Ser170 的羟基侧链建立了中心氢键相互作用,Ser170 是确定11β-HSD1 活性的催化三联体之一 (Ser170, Tyr183 和 Lys 187)。
