Description: Momelotinib, also known as CYT387, is an inhibitor of Janus kinases JAK1 and JAK2, acting as an ATP competitor with IC50 values of 11 and 18 nM, respectively. The inhibitor is significantly less active towards other kinases, including JAK3 (IC50 = 0.16 μM). As of 2011, CYT387 is being developed as a drug for myelofibrosis and currently undergoes Phase I/II clinical trials. Additional potential treatment indications for CYT387 include other myeloproliferative neoplasms, cancer (solid and liquid tumors) and inflammatory conditions.

Additional Information

CYT387 is an ATP-competitive small molecule that potently inhibits JAK1/JAK2 kinases (IC(50)=11 and 18 nM, respectively), with significantly less activity against other kinases, including JAK3 (IC(50)=155 nM). CYT387 inhibits growth of Ba/F3-JAK2V617F and human erythroleukemia (HEL) cells (IC(50) approximately 1500 nM) or Ba/F3-MPLW515L cells (IC(50)=200 nM), but has considerably less activity against BCR-ABL harboring K562 cells (IC=58 000 nM). Cell lines harboring mutated JAK2 alleles (CHRF-288-11 or Ba/F3-TEL-JAK2) were inhibited more potently than the corresponding pair harboring mutated JAK3 alleles (CMK or Ba/F3-TEL-JAK3), and STAT-5 phosphorylation was inhibited in HEL cells with an IC(50)=400 nM. Furthermore, CYT387 selectively suppressed the in vitro growth of erythroid colonies harboring JAK2V617F from polycythemia vera (PV) patients, an effect that was attenuated by exogenous erythropoietin. Overall, research data indicate that the JAK1/JAK2 selective inhibitor CYT387 has potential for efficacious treatment of MPN harboring mutated JAK2 and MPL alleles.
