Abstract

Recent evidence suggests that CDK7 is a novel potential drug target for autosomal dominant polycystic kidney disease (ADPKD) treatment. Herein, on the basis of structural analysis, a hit compound 3 with a novel scaffold was designed and subsequent medicinal chemistry efforts by a rational design strategy were conducted to improve CDK7 inhibitors' potency and selectivity. The representative compound B2 potently inhibited CDK7 with an IC50 value of 4 nM and showed high selectivity over CDKs. Compound B2 showed high potency to inhibit cyst growth and exhibited lower cytotoxicity than THZ1 in an in vitro Madin-Darby canine kidney cyst model. In addition, compound B2 was also highly efficacious in suppressing renal cyst development in an ex vivo embryonic kidney cyst model and in vivo ADPKD mouse model. These results indicate that compound B2 represents a promising lead compound that deserves further investigation to discover novel therapeutic agents for ADPKD.
