Uses

YCH1899 is an orally active PARP inhibitor, with an IC50< 0.001 nM for PARP1/2. YCH1899 exhibits distinct antiproliferation activity against Olaparib (HY-10162)-resistant and Talazoparib (HY-16106)-resistant Capan-1 cells (Capan-1/OP and Capan-1/TP cells) , with IC50 values of 0.89 and 1.13 nM, respectively. YCH1899 has acceptable pharmacokinetic properties in rats[1].

in vivo

YCH1899 (5 mg/kg, intravenous injection ) has a moderate clearance rate in rats[1].
YCH1899 overcomes acquired Talazoparib resistance and has a significant regression of tumor volume in MDA-MB-436/OP (6.25, 12.5, and 25 mg/kg, orally, once a day for 27 days) and Capan-1/R-in vivo xenografts (12.5 and 25 mg/kg, orally, once a day for 21 days ) [1].

Animal Model:MDA-MB-436/OP xenografts and Capan-1/R-in vivo xenografts mice[1]
Dosage:12.5 and 25 mg/kg
Administration:Oral administration
Result:Inhibited MDA-MB-436/OP xenografts tumor growth with T/C of 36.74% and 15.29% at 12.5 and 25 mg/kg
Inhibited Capan-1/R xenografts tumor growth with T/C of 48.92% and 13.87% at 12.5 and 25 mg/kg.
Animal Model:rats[1]
Dosage:5 mg/kg
Administration:Intravenous injection
Result:Had a moderate clearance rate (24.5 mL/min/kg) and half-life (3.25 h).
