Chemical Structure

Biological activities

PD173955 is a Src family-specific tyrosine kinase inhibitor. PD173955 is also an Abl inhibitor.[1] PD173955 inhibits cSrc with an IC50 of 20 nM.[2] PD173955 inhibits Abl with an IC50 of 5 nM. PD173955 is also a potent inhibitor of Kit ligand-dependent cell proliferation through inhibition of the receptor tyrosine kinase c-Kit with an IC50 of 50 nM. In vitro, PD173955 is effective at shutting down the kinase activity of Bcr-Abl with an IC50 of 1-2 nM.[1]

Protocols

In vitro, PD173955 is dissolved in DMSO.[1]
