HM43239 also demonstrated inhibition of SYK, JAK1 2 and TAK1. HM43239 inhibits the proliferation and induces the apoptosis of leukemic cells [1] [2] [3].

R406 (R-406 besylate) is an effective Syk inhibitor (IC50: 41 nM) and shows no effects on Lyn.

JI6 (JAK3 Inhibitor VI) is a potent, selective and orally active FLT3 inhibitor. JI6 exhibits IC50s of ∼40, 8, and 4 nM for FLT3-WT, FLT3-D835Y, and FLT3-D835H, respectively. JI6 also inhibits c-Kit and JAK3, with IC50s of ∼500 and ∼250 nM, respectively. JI6 has research value in acute myeloid leukemia.

BGB-102 (JNJ-26483327) is a kinase inhibitor targeting FLT3 and YES1 and an antagonist targeting EGFR and VEGFR3, which may be useful in the study of macular degeneration and diseases associated with genetic disorders and malformations.

SGI-7079 is a new selective Axl inhibitor. SGI-7079 can be a dose-dependent manner inhibited growth of tumors. It is also a potential therapeutic target for EGFR inhibitor resistance.

Merestinib (LY2801653) is an orally available, small molecule inhibitor of the proto-oncogene c-Met (Ki: 2 nM) with potential antineoplastic activity. Merestinib electively binds to c-Met, thereby inhibiting c-Met phosphorylation and disrupting c-Met signal transduction pathways. This may induce cell death in tumor cells overexpressing c-Met protein or expressing the constitutively activated c-Met protein.
