CAY10747 is an inhibitor of the protein-proteininteraction between heat shock protein 90 (Hsp90) and cell division cycle 37 (Cdc37) and a derivative of celastrol .1It decreases protein levels of the Hsp90-Cdc37 complex and the Hsp90-Cdc37 clients phosphorylated Akt and Cdk4 in A549 cells when used at a concentration of 5 μM. CAY10747 inhibits proliferation of A549, MCF-7, HOS, and HepG2 cells (IC50s = 0.41, 0.64, 0.9, and 0.94 μM, respectively) and induces apoptosis in A549 cells. 1.Li, N., Xu, M., Wang, B., et al.Discovery of novel celastrol derivatives as Hsp90-Cdc37 interaction disruptors with antitumor activityJ.

LSN3106729 hydrochloride, the metabolite of Abemaciclib , is a CDKinhibitor with antitumor activity. LSN3106729 hydrochloride and a CRBN ligand have been used to design PROTAC CDK4 6 degrader[1].
CDK4 6-IN-7, a highly potent and selective orally active inhibitor of CDK4 6, demonstrates impressive inhibition activity with IC50 values of 1.58 nM and 4.09 nM respectively. This compound is particularly valuable for breast cancer research [1].
