sh-1028 mesylate

Oritinib mesylate (SH-1028) is a highly selective, orally active, pyrimidine-based irreversible inhibitor of epidermal growth factor receptor (EGFR) with a low IC50 of 18 nM. It is effective against both EGFR-sensitive and resistant (T790M) mutations and suppresses the proliferation of tumor cells harboring EGFR mutations, irrespective of their sensitivity or resistance.

Oritinib (SH-1028) is an inhibitor of EGFR with IC50s of 18, 0.7, 4, 0.1, 1.4 and 0.89 nM for EGFR (wt), EGFR (L858R), EGFR (L861Q), EGFR (L858R/T790M), EGFR (d746-750), EGFR (d746-750/T790M), respectively. Oritinib can be used in studies about the treatment of non-small cell lung cancer.
