ML753286 has IC50 values of >30, 0.6, and 39.0 μM for the inhibition of P-gp-, BCRP-, and OATP mediated transport, respectively.
体内研究
ML753286 (25- or 50-mg/kg (PO); 10 or 20 mg/kg (IV); 0.083-24 hours) appears to completely inhibit Bcrp functions in rats at 25 mg/kg PO or at 20 mg/kg IV. The tmax values in plasma were 1.4, 4.0, and 4.1 hours in Bcrp KO rats, WT rats pre-administered 25-mg/kg ML753286, and WT rats pre-administered 50-mg/kg ML753286, respectively.
Animal Model:
Male Bcrp KO (Abcg2−/−) and WT (Wistar) Rats
Dosage:
25- or 50-mg/kg (PO); 10 or 20 mg/kg (IV) (Pharmacokinetic Study)
Administration:
PO or IV; 0.083, 0.25, 0.5, 1, 2, 4, 6, 8, and 24 hours
Result:
The tmax values in plasma were 1.4, 4.0, and 4.1 hours in Bcrp KO rats, WT rats pre-administered 25-mg/kg ML753286, and WT rats pre-administered 50-mg/kg ML753286, respectively.
