Title: Synthesis and biological evaluation of N9-cis-cyclobutylpurine derivatives for use as cyclin-dependent kinase (CDK) inhibitors.
Authors: Park SJ, Kim E, Yoo M, Lee JY, Park CH, Hwang JY, Ha JD.
Abstract: A novel 6-aminopurine scaffold bearing an N9-cis-cyclobutyl moiety was designed using structure-based molecular design based on two known CDK inhibitors, dinaciclib and Cmpd-27. A series of novel 6-aminopurine compounds was prepared for structure-activity relationship (SAR) studies of CDK2 and CDK5 inhibitors. Among the compounds synthesized, compound 8l displayed potent CDK2 and CDK5 inhibitory activities with low nanomolar ranges (IC50=2.1 and 4.8nM, respectively) and showed moderate cytotoxicity in HCT116 colon cancer and MCF7 breast cancer cell lines. Here, we report the synthesis and evaluation of novel 6-aminopurine derivatives and present molecular docking models of compound 81 with CDK2 and CDK5.
