Fedratinib (TG-101348) (TG101348) is an ATP-competitive inhibitor of JAK2 (IC50: 3 nM) with significantly less potent activity against JAK3.

Pacritinib (SB1518) (SB1518) is an effective and specific inhibitor of JAK2 and FLT3 (IC50: 23 22 nM, in cell-free assays).

Pacritinib (SB1518) citrate effectively inhibits wild-type JAK2 (IC 50 =23 nM) and the JAK2 V617F mutant (IC 50 =19 nM). It also targets FLT3 (IC 50 =22 nM) and the FLT3 D835Y mutant (IC 50 =6 nM). This compound is utilized in the study of acute myeloid leukemia (AML) and myelofibrosis (MF) [1] [2] [3].

LY2784544(Gandotinib (LY2784544)) is a potent JAK2 inhibitor (IC50: 3 nM), effective in JAK2V617F(Ki: 0.245 nM). The selectivity is higher 8- and 20-fold than JAK1 and JAK3.

Fedratinib hydrochloride hydrate (SAR 302503 hydrochloride hydrate) is a potent, selective, ATP-competitive and orally active JAK2 inhibitor.

JAK2 inhibitor (IC50 = 397 nM). Also inhibits STAT3 and STAT5 phosphorylation. Inhibits cell growth and induces apoptosis in cells expressing the JAK2V617F mutation.

ON044580 is an effective non-ATP-competitive inhibitor of JAK2, characterized as an α-benzoylstyrylbenzyl thioether. It exhibits IC50 values of 1.23 μM for wild type JAK2 and 1.09 μM for the V617F mutation. The compound inhibits JAK2 kinase activity by binding to the STAT-5 binding domain or the allosteric site of JAK2. In JAK2V617F-positive leukemia cells, ON044580 suppresses proliferation and induces apoptosis in Imatinib-resistant chronic myeloid leukemia (CML) cells. It also inhibits both wild type and T315I mutant forms of the BCR-ABL kinase. ON044580 is used in research for myeloproliferative diseases characterized by abnormal JAK STAT signaling.

ZT55, an orally active, highly-selective JAK2 inhibitor with an IC50 of 0.031 μM, inhibits proliferation of JAK2 V617F-expressing HEL cell lines, induces apoptosis and cycle arrest, and effectively inhibits HEL xenograft tumor growth in mice models. Suitable for studies on myeloproliferative neoplasms, polycythemia vera, and primary thrombocythemia, ZT55 offers promising applications.

Pacritinib-d8 is a deuterated compound of Pacritinib. Pacritinib has a CAS number of 937272-79-2. Pacritinib (SB1518) is an effective and specific inhibitor of JAK2 and FLT3 (IC50: 23 22 nM, in cell-free assays).

Pacritinib hydrochloride is a potent inhibitor of wild-type JAK2 (IC50: 23 nM) and the JAK2V617F mutant (IC50: 19 nM), and can be used in the study of acute myeloid leukaemia (AML) and myelofibrosis (MF).
