BTX161 is a thalidomide analog that mediates degradation of CKIα better than lenalidomide in human AML cells and activates DDR and p53, while stabilizing the p53 antagonist MDM2.

An anthelmintic effective for pinworms that shows to be a potent inhibitor of Wnt signaling with EC50 of 10 nM, binds to all CK1 family members in vitro at low nanomolar concentrations and selectively potentiates CK1α kinase activity.
