Pyrotinib maleate

Research use only, not for human use.

Pyrotinib maleate (SHR-1258 maleate)?is a potent and selective EGFR/HER2 dual inhibitor with IC50 of 13/38 nM, respectively.

Pyrotinib maleate (SHR-1258 maleate)?is a potent and selective EGFR/HER2 dual inhibitor with IC50 of 13/38 nM, respectively; displays high selectivity 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 >3,000 nM); exhibits robust anti-tumor effects on HER2-overexpressing xenograft models and sufficiently safety windows in animals as well as favorable pharmacokinetic properties in human.Breast Cancer Phase 3 Clinical.

Pyrotinib dimaleate has high potency in HER2-dependent cell lines (BT474, SK-OV-3), while showing much weaker inhibition in the HER2 negative cell line (MDA-MB-231). Pyrotinib dimaleate inhibits BT474 and SK-OV-3 cells with IC50s of 5.1 and 43 nM, respectively. Pyrotinib dimaleate 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 >3000 nM).

Pyrotinib dimaleate has acceptable bioavailability of 20.6%, 43.5% and 13.5% in nude mice, rats and dogs, respectively. Pyrotinib dimaleate has favorable drug-like physicochemical properties and shows relatively higher oral exposure in human subjects (oral; t1/2=15 h) with a much longer half life than that of preclinical animal species such as mouse (i.v.; t1/2=1.56 h; i.g.; t1/2=2.52 h) and rat (i.v.; t1/2=4.42 h; i.g.; t1/2=3.38 h).
