体外研究 (In Vitro) | Mefuparib hydrochloride (1-10 μM; 48 hours) causes cell apoptosis[1]. Mefuparib hydrochloride (MPH; 1-10 μM; 24 hours) causes V-C8 cells into typical G2/M arrest[1]. Mefuparib hydrochloride (1-10 μM; 24 hours) causes the accumulation of DSB marked by the increased levels of γH2AX in the MDA-MB-436 (BRCA1–/–) cells in a concentration-dependent manner[1]. Mefuparib hydrochloride exerts potent in vitro proliferation-inhibitory effects on cancer cells derived from different human tissues with an average IC50of 2.16 μM (0.12 μM~3.64 μM)[1]. Mefuparib hydrochloride inhibits PARP3 (IC50>10 μM), PARP6 (IC50>10 μM), TNKS1 (IC50=1.6 μM), TNKS2 (IC50=1.3 μM)[1].

体内研究 (In Vivo) | Mefuparib hydrochloride (MPH; 40-160 mg/kg; orally; once every other day; for 21 days) displays dose- and time-dependent killing on V-C8 xenografts accompanied by complete disappearance of some xenografts, especially in the high-dose group[1]. Mefuparib hydrochloride (160 mg/kg; orally; once every other day; for 21 days) inhibits the growth of the BR-05-0028 breast patient-derived xenograft (PDX) without obvious loss of body weight[1]. Mefuparib hydrochloride (10, 20, 40 mg/kg; oral) has a T1/2of 1.07-1.3 hours and a Cmaxof 116-725 ng/mL for SD rats[1]. Mefuparib hydrochloride (5, 10, 20 mg/kg; oral) has a T1/2of 2.16-2.7 hours and a Cmaxof 114-608 ng/mL for cynomolgus monkeys[1].
