CC0651 is a highly selective allosteric inhibitor of human Cdc34 ubiquitin-conjugating enzyme (UCE), inhibiting p27 Kip1 ubiquitination (IC50=1.72 μM) by blocking ubiquitin transfer to substrates, for use in cancer research.
Apcin-A is an anaphase-promoting complex (APC) inhibitor. It interacts strongly with Cdc20 and inhibits the ubiquitination of Cdc20 substrates. Apcin-A can be used to synthesize the PROTAC CP5V.
CP5V, a PROTAC, induces mitotic inhibition, and suppresses cancer cell proliferation. It specifically degrades Cdc20 by linking Cdc20 to the VHL/VBC complex for ubiquitination followed by proteasomal degradation.
