| Momelotinib Usage And Synthesis |
| Description | Momelotinib (CYT387) is an ATP-competitive inhibitor of JAK1/JAK2 with IC50 of 11 nM/18 nM, ~10-fold selectivity versus JAK3. Phase 3. | | In vitro | CYT387 inhibits the proliferation of parental Ba/F3 cells (Ba/F3-wt) stimulated by IL-3 with IC50 of 1400 nM. Furthermore, CYT387 also causes the inhibition of cell proliferation in cell lines constitutively activated by JAK2 or MPL signaling, including Ba/F3-MPLW515L cells, CHRF-288-11 cells and Ba/F3-TEL-JAK2 cells with IC50 of 200 nM, 1 nM and 700 nM, respectively. In addition, CYT387 has been shown to inhibit erythroid colony growth in vitro from JAK2V617F-positive PV patients with similar potency with IC50 of 2μ-4 μM. A recent study shows that CYT387 inhibits PI3K/AKT and Ras/MAPK signaling induced by IL-6 and IGF-1. Moreover, CYT387 induces apoptosis as a single agent and synergizes with the conventional anti-MM therapies bortezomib and melphalan in primary multiple myeloma (MM) cells. | | In vivo | In a murine MPN model, CYT387 normalizes white cell counts, hematocrit, spleen size, and restores physiologic levels of inflammatory cytokines. | | Uses | CYT387 inhibits Janus kinase 1 (JAK1) and Janus kinase (JAK2). These kinases are part of the JAK-STAT pathway and dysregulated functions are involved with hematology, oncology and inflammatory diseases. | | Biological Activity | cyt387, an aminopyrimidine derivative discovered by high-throughput enzyme and cell-based screening along with the optimization using structure-guided medicinal chemistry, is a potent and selective inhibitor of janus kinase 1 (jak1), janus kinase 2 (jak2) and tyrosine kinase 2 (tyk2) with values of 50% inhibition concentration ic50 of 11 nm, 18 nm, 155 nm and 17 nm respectively. recent studies have revealed that cyt387, at low nanomolar concentrations ranging between 500 and 1500 nm, is able to inhibit jak2 signaling pathway, suppress proliferation and induce apoptosis in jak2-dependent hematopoietic cell lines with non-hematopoietic cell lines intact.tyner jw, bumm tg, deininger j, wood l, aichberger kj, loriaux mm, druker bj, burns cj, fantino e, deininger mw. cyt387, a novel jak2 inhibitor, induces hematologic responses and normalizes inflammatory cytokines in murine myeloproliferative neoplasms. blood. 2010;115(25):5232-5240. |
