Biological Activity

Description Pyrotinib dimaleate is a potent and selective irreversible dual tyrosine kinase inhibitor of EGFR and HER2 with IC50 of 0.013 μM and 0.038 μM, respectively.
Targets
EGFR [1]
(Cell-free assay)		 HER2 [1]
(Cell-free assay)
0.013 μM 0.038 μM
In vitro

Pyrotinib (SHR1258), as an EGFR/HER2 dual tyrosine kinase inhibitor, shows excellent in vitro potency, selectivity, and favorable PK profiles.[1]
In vivo

Pyrotinib (SHR1258) displays robust anti-tumor effects on HER2-overexpressing xenograft models and sufficiently safety windows in animals as well as favorable pharmacokinetic properties in human.[1]

Protocol (from reference)

Cell Assay:

[1]
  • Cell lines

    A431, SK-BR-3, NCI-N87

  • Concentrations

    6-7 concentrations (not specific)

  • Incubation Time

    72 h

  • Method

    Cells are incubated in a carbon dioxide (5%CO2) incubator until they reached 85% confluency, subsequently, cell culture medium is replaced by fresh one with Pyrotinib (SHR1258) added in a series of concentrations (6 to 7 concentrations). The cells are then put back to the incubator and cultured continuously. After 72 hours, the activity of the test compounds for inhibiting the cell proliferation is determined by a sulforhodamine B (SRB) method.
Animal Study:

[1]
  • Animal Models

    6-7-week-old female BALB/Ca-nude mice with BT-474/SK-OV-3 xenografts

  • Dosages

    2.5-20 mg/kg, 100 mg/kg

  • Administration

    IV, IG
