NS-018 is a potent inhibitor of Janus kinase 2 (JAK2) enzyme activity and Src-family kinases. It was developed as an oral therapy for the treatment of myelofibrosis. Overall NS-018 has been used in trials studying the treatment of primary myelofibrosis, post-polycythemia vera myelofibrosis, and post-essential thrombocythemia. NS-018 is a highly active JAK2 inhibitor, with an IC50 of 0.72 nM, 46-, 54-, and 31-fold selectivity for JAK2 over JAK1 (IC50, 33 nM), JAK3 (IC50, 39 nM), and Tyk2 (IC50, 22 nM). NS-018 also inhibits Src-family kinases, especially SRC and FYN, and weakly inhibits ABL and FLT3 with 45- and 90-fold selectivity for JAK2, respectively. NS-018 shows potent inhibitory activity against cell lines JAK2V617F or MPLW515L mutations or the TEL-JAK2 fusion gene.

Sample Use Guides

In Vivo Use Guide

In this phase I, dose-escalation portion of a phase I/II study, patients with myelofibrosis received oral NS-018 in continuous 28-day cycles. Once daily NS-018 at 300 mg was chosen as the phase II study dose based on improved tolerability compared with higher doses.

Route of Administration: Oral

In Vitro Use Guide

NS-018 is a highly active JAK2 inhibitor, with an IC50 of 0.72 nM, 46-, 54-, and 31-fold selectivity for JAK2 over JAK1 (IC50, 33 nM), JAK3 (IC50, 39 nM), and Tyk2 (IC50, 22 nM). NS-018 shows potent inhibitory activity against cell lines JAK2V617F or MPLW515L mutations or the TEL-JAK2 fusion gene (expressing a constitutively activated JAK2) with IC50 of 11-120 nM, but has only minimal cytotoxicity against most other hematopoietic cell lines that have no constitutively activated JAK2.
