What is CKI-7 Dihydrochloride?

CKI-7 dihydrochloride is one of the isoquinoline sulfonamide, and is an ATP-competitive inhibitor that selectively inhibit casein kinase 1 (CK1). As a serine/ threonine kinase, CK1 regulates various processes such as nuclear export, cell cycle, cell division, and apoptosis. CKI-7 dihydrochloride is known for induce retinal progenitor cells from human ES and iPS cells in combination with SB431542 and Y-27632 under serum-free and feeder-free conditions.

What is IWP-2?

IWP-2 inactivates porcupine (Porcn), a membrane-bound o-acyltransferase (MBOAT), and suppresses palmitoylation of Wnt proteins. As a result, it blocks phosphorylation of Wnt-dependent Lrp-6 receptor and Dvl2, and accumulation ofβ-catenin. It is known that it promotes differentiation of human iPS cells into cardiomyocytes.
