chir99021

CHIR-99021 (CT99021) is an activator of the Wnt β-catenin signaling pathway and a GSK-3α β inhibitor (IC50=10 6.7 nM) with selective and oral activity.CHIR-99021 induces cellular autophagy, which enhances self-renewal in mouse and human embryonic stem cells.

A 83-01 (ALK5 Inhibitor IV) is an inhibitor of the TGF-β type I receptors ALK5, ALK4, and ALK7 (IC50=12 45 7.5 nM). A 83-01 promotes the reprogramming of mouse fibroblasts into iPSCs. A 83-01 can be used in organoid cultures.

Tranylcypromine (2-PCPA) hydrochloride (SKF-385 HCl), a Monoamine Oxidase inhibitor, is effective in the treatment of major depression, dysthymic disorder, and atypical depression.

AS8351 (NSC51355) is a histone demethylase inhibitor. It has been used in combination with CHIR99021, A 83-01, BIX01294, SC-1, Y-27632, OAC2, SU 16f, and JNJ-10198409 to induce reprogramming of human fetal lung fibroblasts into functional cardiomyocytes.

3-Deazaneplanocin A (DZNep) is a dual inhibitor of histone methyltransferase (EZH2) and S-adenosylhomocysteine hydrolase (AHCY) with antipoxidative activity that inhibits hepatic, renal, peritoneal, and airway fibrosis by inducing proteasomal degradation of its targets and reducing toxicity in animal models.

Lipoxygenin is an inhibitor of 5-lipoxygenase (5-LO) with an IC50value of 5 μM for inhibition of 5-LO product synthesis in isolated human granulocytes stimulated with the cation ionophore A23187 .1It inhibits hedgehog-dependent signaling in Shh-LIGHT2 cells and TGF-β-, activin A-, bone morphogenic protein (BMP)-, or Wnt-dependent signaling in HEK293T cells (IC50s = 9.3, 3.2, 8.2, 9.6, and 3.7 μM, respectively, in luciferase reporter assays). Lipoxygenin (5 and 10 μM) increases levels of troponin T (TnnT), a marker of cardiomyocyte differentiation, in human induced pluripotent stem cells (iPSCs) stimulated with BMP4 and the glycogen synthase kinase 3 (GSK3) inhibitor CHIR99021 .

Laduviglusib trihydrochloride (CT99021 trihydrochloride) is a selective glycogen synthase kinase 3 (GSK-3) inhibitor with IC50s of 10 nM and 6.7 nM for GSK-3α and GSK-3β. Laduviglusib trihydrochloride inhibits human GSK-3β with a Ki of 9.8 nM. Laduviglusib trihydrochloride is an activator of Wnt β-catenin signaling. Laduviglusib trihydrochloride induces autophagy.

Laduviglusib [CHIR 99021; CHIR99021; CHIR-99021; CT99021; CT 99021; CT-99021] is a potent, selective small-molecule inhibitor of glycogen synthase kinase 3 (GSK-3) with the formula C22H18ClN5O. It is used extensively in biomedical research to explore the role of GSK-3 in various cellular processes and diseases.
