JAK2 Activator

Butyzamide is an orally active activator of Mpl, a thrombopoietin (TPO) receptor. Butyzamide increases the phosphorylation level of JAK2, STAT3, STAT5 and MAPK. Butyzamide increases the level of platelets in mouse xenotransplantation assay.

Broussonin E is a phenolic compound and shows anti-inflammatory activity. Broussonin E can suppress inflammation by modulating macrophages activation statevia inhibiting the ERK and p38 MAPK and enhancing JAK2-STAT3 signaling pathway. Broussonin E can be used for the research of inflammation-related diseases such as atherosclerosis.

Secretoneurin, rat is a 33-amino acid neuropeptide produced by proteolytic processing of chromogranin II, widely distributed in the central and peripheral nervous systems, and its release is calcium-dependent. Secretoneurin, rat modulates the activities of caspase-3, caspase-1, the NLRP3 inflammasome, IGF-1R, VEGFR1, VEGFR2, FGFR3, AMPK, ERK1/2/MAPK, and Jak2/Stat3 pathways. Secretoneurin, rat regulates neuronal apoptosis, synaptic structure, inflammation, neurogenesis, angiogenesis, oxidative stress, cardiomyocyte hypertrophy, dopamine release, and cell migration and proliferation. Secretoneurin, rat is used in studies of global cerebral ischemia, myocardial infarction, stroke, and cardiac hypertrophy.

Mocravimod (KRP-203 free base) is a sphingosine-1-phosphate receptor (S1PR) modulator that blocks the signal required by T cells to egress from lymph nodes and other lymphoid organs. Mocravimod preferentially binds to S1PR1 over S1PR2 and S1PR3 in cardiomyocytes. Mocravimod significantly lowered the concentration of reactive oxygen species (ROS), prevented mitochondrial permeability transition pore opening, boosted mitochondrial membrane potential (MMP), and increased phosphorylation of AKT, EKR, GSK-3β, JAK2, and STAT3. Mocravimod retains T cell effector function. Mocravimod can be used for the study of acute myelogenous leukemia, diabetes and Myocardial Ischemia-Reperfusion Injury (MIRI).

JAK2 activator 1 is an orally active and selective JAK2 activator derived from Proanthocyanidin A1 (HY-N2344) (EC₅₀ = 64 nM). JAK2 activator 1 directly binds to JAK2, triggers conformational changes, and achieves allosteric activation of the JAK2/STAT3 signaling pathway. JAK2 activator 1 promotes hematopoietic recovery in chemotherapy-induced myelosuppression by protecting hematopoietic stem cells from Carboplatin (HY-17393)-induced damage. JAK2 activator 1 does not promote the proliferation of A549, HepG2, or CaCo2 tumor cells, nor does it attenuate the antitumor effect of Carboplatin. JAK2 activator 1 can be used in research related to cancer chemotherapy-induced myelosuppression.
