On April 25, 2019, Sun, Shuai-Shuai; Chen, Junyou; Zhao, Rui; Bierer, Donald; Wang, Jun; Fang, Ge-Min; Li, Yi-Ming published an article.Product Details of 98946-18-0 The title of the article was Efficient synthesis of a side-chain extended diaminodiacid for solid-phase synthesis of peptide disulfide bond mimics. And the article contained the following:

Solid-phase incorporation of diaminodiacids is one of the most effective approaches for synthesis of peptide disulfide bond mimics. One of a limitation of current diaminodiacid toolbox is that only four-atom linkage mimics are available that may not fully meet the activity optimization requirement. In this work, we developed a new diaminodiacid that contains a five-atom thioether (C-C-S-C-C) bridge for the first time. With this diaminodiacid in hand, we successfully obtained oxytocin containing new disulfide bond mimic by solid phase peptide synthesis. The experimental process involved the reaction of tert-Butyl trichloroacetimidate(cas: 98946-18-0).Product Details of 98946-18-0

And the article contained the following:

With the aim of overcoming gefitinib resistance, a series of novel quinazoline derivatives bearing an adamantyl group on the aniline ring were synthesized as potent epidermal growth factor receptor (EGFR) inhibitors. Most of these analogs are comparable to gefitinib in their ability to inhibit non-small cell lung cancer (NSCLC) cell lines, and several also exhibited significantly enhanced anti-tumor potency. Specifically, compound I, with an IC50 value of 2.06 μM against A431 cells with the wild-type EGFR and of 0.009 μM against the gefitinib-sensitive cells, displayed approx. 5-fold higher potency than the lead compound to inhibit the cells harboring the EGFRT790M mutant. In addition, the mol. simulation and Western blot anal. results also indicated that these compounds effectively interfered with the EGFRT790M activity, and may serve as a new alternative structure to develop more effective antitumor agents. The experimental process involved the reaction of 2-Chloro-4-nitrobenzoic acid(cas: 99-60-5).Computed Properties of 99-60-5
