Benzonitrile, 3-[[4-chloro-5-[[3-(2,3-dihydro-1,4-benzodioxin-6-yl)-2-methylphenyl]methoxy]-2-[[2-(1-piperazinylcarbonyl)-1-piperidinyl]methyl]phenoxy]methyl]-

BMS-1166-N-piperidine-CO-N-piperazine incorporates a ligand for PD-1/PD-L1 immune checkpoint, and a PROTAC linker. BMS-1166-N-piperidine-CO-N-piperazine can be used in the synthesis of PROTAC PD-1/PD-L1 degrader-1 (HY-131183). PROTAC PD-1/PD-L1 degrader-1 inhibits PD-1/PD-L1 interaction with an IC50 of 39.2 nM[1].
