The reaction of an aromatic heterocycle with a proton is called a protonation. One of articles about this theory is 《Design, Synthesis, and Biological Evaluation of Linear Aliphatic Amine-Linked Triaryl Derivatives as Potent Small-Molecule Inhibitors of the Programmed Cell Death-1/Programmed Cell Death-Ligand 1 Interaction with Promising Antitumor Effects In Vivo》. Authors are Guo, Jialin; Luo, Longlong; Wang, Zhihong; Hu, Naijing; Wang, Wei; Xie, Fei; Liang, Erguang; Yan, Xinlin; Xiao, Junhai; Li, Song.The article about the compound:5-(Chloromethyl)nicotinonitrilecas:562074-59-3,SMILESS:N#CC1=CN=CC(CCl)=C1).Name: 5-(Chloromethyl)nicotinonitrile. Through the article, more information about this compound (cas:562074-59-3) is conveyed.
A series of novel linear aliphatic amine-linked triaryl derivatives as inhibitors of PD-1/PD-L1 were designed, synthesized, and evaluated in vitro and in vivo. In this chem. series, compound I showed the most potent inhibitory activity and binding affinity with hPD-L1, with an IC50 value of 12 nM and a KD value of 16.2 pM, showing a binding potency approx. 2000-fold that of hPD-1. Compound I could bind with hPD-L1 on the cellular surface and competitively block the interaction of hPD-1 with hPD-L1. In a T cell function assay, I restored the T cell function, leading to increased IFN-γ secretion. Moreover, in a humanized mouse model, compound I significantly inhibited tumor growth without obvious toxicity and showed moderate PK properties after i.v. injection. These results indicated that I is a promising lead for further development of small-mol. PD-1/PD-L1 inhibitors for cancer therapy.
As far as I know, this compound(562074-59-3)Name: 5-(Chloromethyl)nicotinonitrile can be applied in many ways, which is helpful for the development of experiments. Therefore many people are doing relevant researches.
