The article was titled 《An Alkynylpyrimidine-Based Covalent Inhibitor That Targets a Unique Cysteine in NF-κB-Inducing Kinase》.Computed Properties of C4H2Cl2N2 The article contains the following contents:
NF-κB-inducing kinase (NIK) is a key enzyme in the noncanonical NF-κB pathway, of interest in the treatment of a variety of diseases including cancer. Validation of NIK as a drug target requires potent and selective inhibitors. The protein contains a cysteine residue at position 444 in the back pocket of the active site, unique within the kinome. Anal. of existing inhibitor scaffolds and early structure-activity relationships (SARs) led to the design of C444-targeting covalent inhibitors based on alkynyl heterocycle warheads. Mass spectrometry provided proof of the covalent mechanism, and the SAR was rationalized by computational modeling. Profiling of more potent analogs in tumor cell lines with constitutively activated NIK signaling induced a weak antiproliferative effect, suggesting that kinase inhibition may have limited impact on cancer cell growth. This study shows that alkynyl heterocycles are potential cysteine traps, which may be employed where common Michael acceptors, such as acrylamides, are not tolerated. In the experiment, the researchers used many compounds, for example, 2,4-Dichloropyrimidine(cas: 3934-20-1Computed Properties of C4H2Cl2N2)
2,4-Dichloropyrimidine(cas: 3934-20-1) is a member of organic chlorides. Almost all organochlorine compounds are synthesized. It is widely used as intermediates, solvents and pesticides of chemical synthetic products.Computed Properties of C4H2Cl2N2
