生物活性：
Oritinib (SH-1028) mesylate is a selective, orally active, and pyrimidine-based irreversible inhibitor of EGFR with an IC50 of 18 nM. Oritinib (SH-1028) mesylate exhibits potent activity against EGFR sensitive and resistant (T790 M) mutations. Oritinib (SH-1028) mesylate significantly inhibits proliferation of tumor cells with EGFR sensitive and resistant mutation.
体内研究：
Oritinib (SH-1028) (p.o.; once daily for consecutive 14 days; 2.5-15 mg/kg) mesylate inhibits EGFR-mutant tumor progression but not wild-type EGFR in vivo.Oritinib (SH-1028) (p.o.; once daily for consecutive 14 days; 2.5-15 mg/kg) mesylate only induces a moderate tumor growth inhibition in A431 (wild-type EGFR) tumor xenografts, while causes profound and sustained tumor shrinkage in both NCI-H1975 and PC-9 xenograft models with EGFR mutations with 5 mg/kg/day.Oritinib (SH-1028) (p.o.; once daily for consecutive 14 days; 2.5-15 mg/kg) mesylate shows good bioavailability, and is distributed extensively from the plasma to the tissues with Tmax of 1.5-2 h, and AUC0–t values of SH-1028 in plasma are 118, 300 and 931 ng × h/ml on Day 1, while 272, 308 and 993 ng × h/ml on Day 14.Animal Model:Nu/Nu female nude mice (6-8 weeks) bearing human lung cancer cell lines
Dosage:2.5, 5, and 15 mg/kg (SH-1028) and control group (osimertinib, 5 mg/kg)
Administration:p.o.; once daily for consecutive 14 days
Result:Only induced a moderate tumor growth inhibition in A431 (wild-type EGFR) tumor xenografts, while caused profound and sustained tumor shrinkage in both NCI-H1975 and PC-9 xenograft models with EGFR mutations with 5 mg/kg/day.
体外研究：
Oritinib (SH-1028) (72 hours; 10 μmol/L and the 3-fold dilution; nine times) mesylate selectively inhibits EGFR-mutated NCI-H1975, H3255 and PC-9 cells, with IC50 values of 3.93, 9.39 and 7.63 nM, respectively, which is more sensitive than the inhibition of wild-type EGFR in A431 cells.
