jak2-in-4

JAK2-IN-4 is a selective JAK2 JAK3 inhibitor, with IC50 values of 0.7 nM and 23.2 nM for JAK2 and JAK3, respectively.

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).

TAS05567 is a potent, highly selective, and ATP-competitive Syk inhibitor (IC50: 0.37 nM), showing >70% inhibition of Syk and four other kinases [FLT3 (IC50: 10 nM), JAK2 (IC50: 4.8 nM), KDR (IC50: 600 nM), RET (IC50: 29 nM)] in a panel of 192 kinases.

YLIU-4-105-1 is a type II JAK2 inhibitor. Demonstrating in vivo pharmacological activity, YLIU-4-105-1 reduces splenic weight, decreases blood reticulocyte counts in a dose-dependent manner, and inhibits pSTAT5.

JAK HDAC-IN-4 (compound 11 i) is a dual inhibitor targeting both JAK2 and HDAC6, with IC50 values of 0.49 nM and 12 nM respectively. It inhibits cell proliferation and the production of nitric oxide. In a mouse model induced by Imiquimod, JAK HDAC-IN-4 ameliorates psoriasiform skin lesions with low toxicity.

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.

RET-IN-4 is a highly effective and specific RET inhibitor that can be administered orally. It demonstrates remarkable potency, with IC50 values of 1.29 nM, 1.97 nM, and 0.99 nM for inhibiting RET variants including RET (WT), RET (V804M), and RET (M918T), respectively. Moreover, RET-IN-4 exhibits superior selectivity towards kinases JAK2 (IC50 of 4.4 nM) and FLT3 (IC50 of 30.8 nM). Additionally, RET-IN-4 possesses pronounced anticancer properties.

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).

SJ1008030 (compound 8) formic is a selective JAK2 degrader from the PROTAC class, exhibiting efficacy in inhibiting MHH-CALL-4 leukemia cell growth with an IC50 of 5.4 nM, and is potentially applicable for leukemia research [1].

Antiproliferative Agent-34 (Compound A14), a multitarget kinase inhibitor, demonstrates IC50 values of 177 nM for EGFR L858R T790M and 1567 nM for EGFR WT. Additionally, it inhibits JAK2, ROS1, FLT3, FLT4, and PDGFRα with respective IC50s of 30.93 nM, 106.90 nM, 108.00 nM, 226.60 nM, and 42.53 nM. In normoxic conditions, it suppresses the proliferation of H1975 and HCC827 cells with IC50 values below 40 nM, while under hypoxic conditions, its potency increases 4-6 fold, yielding IC50 values less than 10 nM [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.
