It inhibits BT474 and SK-OV-3Pyrotinib cells with IC50s of 5.1 and 43 nM, respectively. Pyrotinib displays high selectivity as HKI-272 when tested in a panel of different kinases such as KDR, c-Kit, PDGFRβ, c-Src and C-Met (c-Src with an IC50 of 790 nM, and others over 3000 nM).\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eIn Vivo:\u003c\/strong\u003e\u003c\/p\u003e\u003cp style=\"padding-left:1em;\"\u003ePyrotinib has acceptable bioavailability of 20.6%, 43.5% and 13.5% in nude mice, rats and dogs, respectively. Pyrotinib has favorable drug-like physicochemical properties and shows relatively higher oral exposure in human subjects with a much longer half life than that of preclinical animal species such as mouse, rat and dog. The TGI % (tumor growth inhibition) of Pyrotinib on day 21 is 109%, 157%, 159% at the doses of 5 mg\/kg, 10 mg\/kg, 20 mg\/kg respectively. Pyrotinib in SK-OV-3 ovarian xenograft model shows TGI% on day 21 of 2%, 12%, 83% at the doses of 2.5 mg\/kg, 5 mg\/kg, 10 mg\/kg respectively), which further confirms its robust in vivo antitumor efficacy at 10 mg\/kg.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eProducts are for research use only.
