jak1 in 4

JAK1-IN-4 is a selective JAK1 inhibitor (IC50s: 85 nM, 12.8 μM and >30 μM for JAK1, JAK2, and JAK3, respectively). JAK1-IN-4 inhibits STAT3 phosphorylation in NCI-H 1975 cells (IC50, 227 nM).

JAK1 TYK2-IN-4 serves as a dual inhibitor targeting both JAK and TYK2, displaying IC50 values of 39 nM and 21 nM, respectively. It is also orally bioavailable [1].

IL-4 inhibitor is an inhibitor of IL-4.1It binds to IL-4 with a Kdvalue of 1.8 μM and inhibits IL-4 activity in a cell-based reporter assay (EC50= 1.81 μM). It is selective for IL-4 over IL-13 (EC50= 18.2 μM). IL-4 inhibitor inhibits IL-4-induced STAT6 phosphorylation in THP-1 monocytes (EC50= 3.1 μM), indicating inhibition of the IL-4-JAK1-STAT6 signaling pathway.

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.

JAK2 FLT3-IN-1 (TFA) is an orally active dual inhibitor of JAK2 (IC50: 0.7 nM) and FLT3 (IC50: 4 nM) that demonstrates anticancer effects, also affecting JAK1 (IC50: 26 nM) and JAK3 (IC50: 39 nM).

JAK HDAC-IN-2, a potent 2-amino-4-phenylaminopyrimidine dual-target inhibitor, effectively suppresses JAK1 2 and HDAC3 6 at nanomolar concentrations. This compound exhibits proapoptotic properties, inhibits histone deacetylation, and impedes STAT3 phosphorylation, demonstrating notable antiproliferative activity against various hematological malignancies and solid tumors [1].

Flonoltinib maleate is an orally effective dual JAK2 FLT3 inhibitor, with IC50 values of 0.7 nM for JAK2, 4 nM for FLT3, 26 nM for JAK1, and 39 nM for JAK3. Known as JAK2 FLT3-IN-1, it exhibits anticancer activity.
