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.
Imatinib carbaldehyde (also known as CGP-57148B carbaldehyde) is a compound derived from Imatinib, an inhibitor of the ABL protein. Imatinib carbaldehyde binds to the IAP ligand with the assistance of a linker, resulting in the formation of SNIPER[1].
