Abstract 696: Development of selective CDK8 inhibitors for colorectal cancer and mantle cell lymphoma treatment.

Abstract: CDK8 is a kinase component of the mediator complex which functions as a bridge between a basal transcriptional machinery and specific transcription factors. CDK8 is amplified and differentially expressed in colorectal cancer and in certain hematological malignancies such as mantle cell lymphomas. Cells that express elevated CDK8 levels are highly dependent on its expression for proliferation. Here we report development of first-in-class selective inhibitors CDK8. Compounds from the SEL120 series have binding a… Show more

“…The former preparation of reagents 3 and 4 for the C-N cross coupling proved challenging during scale-up and led us to circumvent the Sandmeyer iodination from 3 to 4. 8 Gratifyingly, an alternative route consisting of a reductive amination, a Finkelstein reaction, and bromination allowed us to access intermediate 4 in good to excellent yields without any column chromatography. 9 A careful optimization of the nitration and reduction conditions delivered intermediate 3 in good yield, purified by recrystallization.…”
