rar

PROTAC RAR Degrader-1, an RAR degrader, consists of a cIAP1 ligand binding group, a linker, and an RAR ligand binding group. It achieves maximal RAR degradation at a concentration of 30 μM in HT1080 cells. Degradation inducers that utilize cIAP1 are known as 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].
