Laduviglusib (CHIR-99021) trihydrochloride is a well-characterized small molecule inhibitor that specifically targets glycogen synthase kinase-3 alpha and beta (GSK-3α/β). It exhibits potent inhibitory activity with IC50 values of 10 nM for GSK-3α and 6.7 nM for GSK-3β. Importantly, it demonstrates high selectivity, being over 500-fold more selective for GSK-3 compared to other kinases such as CDC2 and ERK2, as well as a broad range of other protein kinases.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
