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.
CC0651 is an allosteric inhibitor of the human Cdc34 ubiquitin-conjugating enzyme. CC0651 potently inhibits the ubiquitination of p27Kip1 (IC50: 1.72 μM).
