NSC 33994

NSC-33994 (82058-16-0) is a remarkably potent and selective JAK2 inhibitor (IC50 = 60 nM). Displays no effect on Src and TYK2 tyrosine kinase activity at a concentration of 25 μM.1?Suppresses JAK2-V617F-mediated human pathological cell growth?in vitro?and?in vivo2?and is concomitant with the disruption of intracellular vimentin filaments3. NSC-33994 reduces the tumorigenic potential of T98G glioblastoma cells?in vitro?and?in vivo.4

NSC-33994 is novel inhibitor of JAK2 tyrosine kinase (Janus kinase 2 ). Janus kinase 2 (JAK2) plays a crucial role in the pathomechanism of myeloproliferative disorders and hematological malignancies.
