CR8（Cat No.:I006293）is a potent and selective inhibitor of cyclin-dependent kinases (CDKs), particularly CDK1, CDK2, CDK5, and CDK9, which are critical for regulating cell cycle progression and transcription. By inhibiting these kinases, CR8 induces cell cycle arrest and apoptosis, making it a valuable tool for cancer research. Its ability to target CDK9 also impacts RNA polymerase II-mediated transcription, contributing to the suppression of oncogene expression. CR8 has demonstrated efficacy in preclinical models of cancer, offering potential therapeutic applications in targeting CDK-driven malignancies and other diseases involving abnormal cell proliferation.
