TG101348 (SAR302503) is an orally available inhibitor of Janus kinase 2 (JAK-2) developed for the treatment of patients with myeloproliferative diseases including myelofibrosis. TG101348 acts as a competitive inhibitor of protein kinase JAK-2 with IC50=6 nM; related kinases FLT3 and RET are also sensitive with IC50=25 nM and IC50=17 nM respectively. Significantly less activity was observed against other tyrosine kinases including JAK3 (IC50=169 nM).
