Hydrochloride salt of ZM 323881, a potent and selective inhibitor of vascular endothelial growth factor receptor-2 (VEGFR-2) with application towards cancer treatments.

ChEBI: ZM 323881 hydrochloride is a hydrochloride obtained by combining ZM 323881 with one molar equivalent of hydrochloric acid. It has a role as a vascular endothelial growth factor receptor antagonist and an EC 2.7.10.1 (receptor protein-tyrosine kinase) inhibitor. It contains a ZM 323881(1+).

ZM323881 is a selective inhibitor of VEGFR-2 with an IC50 value of 2 nM. ZM323881 is selective for VEGFR-2 over VEGFR-1 and other receptor tyrosine kinases including PDGFRβFGFR1EGFR and erbB2. ZM323881 inhibited VEGF-A-induced endothelial cell proliferation with an IC50 value of 8 nM.''ZM323881 is also known as (5‐{[7‐(benzyloxy) quinazolin‐4‐yl]amino}‐4‐fluoro‐2‐methylphenol). It is capable of blocking the efflux function and altering breast cancer resistant protein (BCRP)-related multidrug resistance (MDR).

VEGFR2: 2 nM (IC₅₀)
