Discovery of CDK8/19 inhibitors as lead compounds for IL-6–dependent lymphoma enabled by the formal synthesis of cortistatin A
A formal synthesis of cortistatin A, a marine-derived steroidal alkaloid with potent anti-angiogenic and antileukemic activities, was achieved via a unique synthetic strategy that leveraged a late-stage SmI2-mediated oxa-bridge translocation. The de novo–synthesized simplified analog CA411 was evaluated across 38 cell...
