4-Cyanobenzyl bromide(cas: 17201-43-3) can reacts with 2H-tetrazole in the presence of KOH to yield 4-[(2H-tetra-zol-2-yl)methyl]benzonitrile. And it may be used in the synthesis of ligands containing a chelating pyrazolyl-pyridine group with a pendant aromatic nitrile.Reference of 4-Cyanobenzyl bromide

The article conveys some information:

Design and synthesis of a series of pyrido[3,2-d]pyrimidine-based toll-like receptor 7/8 dual agonists, e.g., I that exhibited potent and near-equivalent agonistic activities toward TLR7 and TLR8. In vitro, compounds significantly induced the secretion of IFN-α, IFN-γ, TNF-α, IL-1β, IL-12p40, and IP-10 in human peripheral blood mononuclear cell assays. In vivo, compounds significantly suppressed tumor growth in CT26 tumor-bearing mice by remodeling the tumor microenvironment. Addnl., compounds markedly improved the antitumor activity of PD-1/PD-L1 blockade. These results demonstrated that TLR7/8 agonists held great potential as single agents or in combination with PD-1/PD-L1 blockade for cancer immunotherapy.4-Cyanobenzyl bromide(cas: 17201-43-3Reference of 4-Cyanobenzyl bromide) was used in this study.
