WHI-P180 is a multi-kinase inhibitor. It inhibits human proto-oncogene receptor tyrosine kinase RET (Rearranged during Transfection) and kinase insert domain receptor (KDR) with IC₅₀ values of 4.5 nM and 66 nM respectively. It inhibits epidermal growth factor receptor (EGFR) kinase with an IC₅₀ of 4.0 μM and also inhibits Janus kinase 3 (JAK3). It exhibits potent anti-graft-versus-host disease activity and IgE-mediated mast cell responses in vitro and in vivo.
