生物活性:
KY19382 is a potent and orally active dual inhibitor of CXXC5-DVL and GSK3β, with IC50s of 19 and 10 nM, respectively. KY19382 activates Wnt/β-catenin signaling through inhibitory effects on both CXXC5-DVL interaction and GSK3β activity. KY19382 can be used for the research of high fat diet (HFD) induced metabolic diseases.

体内研究:
KY19382 (0.1 mg/kg; i.p. once daily for 2 weeks) delays growth plate senescence in older mice and promotes growth plate maturation in rapidly growing young mice.KY19382 (0.1 mg/kg; i.p. once daily for 10 weeks) significantly increases the length of tibiae in mice.KY19382 (5 mg/kg; i.p.) displays a relatively favorable bioavailability (F=16.74%), showing half-life of 16.20 h and an exposure level of 6,555.79 ng?h/ml.KY19382 (A3051) (25 mg/kg; p.o. once daily for 16 weeks) shows reduction in adipocyte size and anti-inflammatory effects.A3051 (25 mg/kg; p.o. once daily for 5 days) reduces fasting glucose in mice.A3051 (25 mg/kg; p.o. once daily for 3 weeks) reduces the hepatosteatosis in mice.Animal Model:C57BL/6 male mice (7-weeks-old or 3-weeks-old)
Dosage:0.1 mg/kg
Administration:I.p. once daily for 2 weeks
Result:Increased nuclear β-catenin in the growth plate chondrocytes dramatically.Elevated the height of each growth plate zone and BrdU-positive cells.Did not affect the cartilage resorption of rapidly growing young mice.
Animal Model:SD male rats
Dosage:1 mg/kg for i.v. and 5 mg/kg for i.p. (Pharmacokinetic Analysis)
Administration:I.v. and i.p. administration
Result:I.v.: t1/2=3.33 h; AUC=7832.81 ng?h/mL; CL=0.12 L/h/kg.I.p.: t1/2=16.20 h; F=16.74%; Cmax=463.37 ng/mL.
