PROTAC RAR Degrader-1 comprises a cIAP1 ligand binding group, a linker and a RAR ligand binding group. PROTAC RAR Degrader-1 is an RAR degrader. Maximal RAR degradation at 30 μM concentration in HT1080 cells. Degradation inducers based on cIAP1 are called specific and non-genetic IAP-dependent protein erasers (SNIPERs)[1].
Ch55-O-C3-NH2, also known as RAR ligand 1, is a ligand derived from the Ch55 compound that specifically targets RAR. Through a linker, Ch55-O-C3-NH2 interacts with cIAP1 ligand Bestatin to form SNIPER[1].
