BMS-1166-N-piperidine-COOH, a derivative of the potent PD-1/PD-L1 interaction inhibitor BMS-1166, serves as a key component in the design of PROTAC PD-1/PD-L1 degrader-1 (HY-131183). By binding to an E3 ligase ligand via a linker, this moiety facilitates the targeted degradation of PD-1/PD-L1, offering a novel approach to modulate immune checkpoint pathways. BMS-1166 itself is a highly effective inhibitor of the PD-1/PD-L1 interaction, with an IC50 of 1.4 nM, and it counteracts the immune-suppressive effects of the PD-1/PD-L1 checkpoint on T cell activation. This innovative strategy combines the inhibitory potency of BMS-1166 with the degradation capability of PROTAC technology, providing a promising tool for advancing cancer immunotherapy and immune-related research.

Providing storage is as stated on the product vial and the vial is kept tightly sealed, the product can be stored for up to 24 months.
Wherever possible, you should prepare and use solutions on the same day. However, if you need to make up stock solutions in advance, we recommend that you store the solution as aliquots in tightly sealed vials at -20°C. Generally, these will be useable for up to one month. Before use, and prior to opening the vial we recommend that you allow your product to equilibrate to room temperature for at least 1 hour.
