CHEMBL5738727

In vitro kinase inhibition assay: An in vitro kinase assay was performed to evaluate the kinase suppression activity of the most promising cytotoxic candidates 4b, 4j against four different receptor tyrosine kinases (RTKs) - namely epidermal growth factor receptor (EGFR), human epidermal growth factor receptor (HER2), vascular endothelial growth factor receptor-2 (VEGFR-2) and platelet-derived growth factor receptor (PDGFR). The activities of the examined compounds against EGFR, HER2, PDGFR-β, and VEGFR2 were in vitro tested using Abcam's Human In cell ELISA Kit (ab 126419) for EGFR, ADP-Glo TM Kinase Assay for Her2, PDGFR-β, active, recombinant protein expressed in Sf9 cells for VEGFR2 (KDR) Kinase Assay Kit Catalog No. 40325, respectively.
