Abstract: With small macrocyclic “probes” from our proprietary library in the low nanomolar range IC50, we turned our attention to CDK9 inhibitors with good selectivity profile against CDK1/2/5/7 as a starting point for building bifunctional small macrocyclic kinase degraders. Although the ATP binding site of the CDKs are structurally similar, developing a small macrocyclic PROTAC degrader could enhanced the selectivity of the parent molecule by preferential ubiquitination of lysine exposed residues among the different CDKs…
