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.

CHIR-99021 HCl (Laduviglusib HCl) is a highly potent and selective inhibitor of GSK-3α β, with IC50 values of 10 nM and 6.7 nM respectively. It demonstrates remarkable selectivity for GSK-3, with over 500-fold selectivity over CDC2, ERK2, and other protein kinases. Additionally, CHIR-99021 HCl serves as a robust activator of the Wnt β-catenin signaling pathway. Moreover, it exhibits the ability to enhance self-renewal in both mouse and human embryonic stem cells. Furthermore, CHIR-99021 HCl induces autophagy [1] [2] [3].

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.

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.

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.
