《N-Hydroxyphthalimide/benzoquinone-catalyzed chlorination of hydrocarbon C-H bond using N-chlorosuccinimide》 was published in Organic & Biomolecular Chemistry in 2019. These research results belong to Li, Zi-Hao; Fiser, Bela; Jiang, Biao-Lin; Li, Jian-Wei; Xu, Bao-Hua; Zhang, Suo-Jiang. Recommanded Product: 620-20-2 The article mentions the following:

The direct chlorination of C-H bonds has received considerable attention in recent years. In this work, a metal-free protocol for hydrocarbon C-H bond chlorination with com. available N-chlorosuccinimide (NCS) catalyzed by N-hydroxyphthalimide (NHPI) with 2,3-dicyano-5,6-dichlorobenzoquinone (DDQ) functioning as an external radical initiator is presented. Aliphatic and benzylic substituents and also heteroaromatic ones were found to be well tolerated. Both the experiments and theor. anal. indicate that the reaction goes through a process wherein NHPI functions as a catalyst rather than as an initiator. On the other hand, the hydrogen abstraction of the C-H bond conducted by a PINO species rather than the highly reactive N-centered radicals rationalizes the high chemoselectivity of the monochlorination obtained by this protocol as the latter is reactive towards the C(sp3)-H bonds of the monochlorides. The present results could hold promise for further development of a nitroxy-radical system for the highly selective functionalization of the aliphatic and benzylic hydrocarbon C-H. In the experiment, the researchers used 3-Chlorobenzylchloride(cas: 620-20-2Recommanded Product: 620-20-2)

Electric Literature of C8H6Cl2O3On October 14, 2021 ,《Structure-Guided Design of a Small-Molecule Activator of Sirtuin-3 that Modulates Autophagy in Triple Negative Breast Cancer》 was published in Journal of Medicinal Chemistry. The article was written by Zhang, Jin; Zou, Ling; Shi, Danfeng; Liu, Jie; Zhang, Jifa; Zhao, Rongyan; Wang, Guan; Zhang, Lan; Ouyang, Liang; Liu, Bo. The article contains the following contents:

Sirtuin-3 (SIRT3) is an NAD+-dependent protein deacetylase localized primarily in the mitochondria with many links to different types of human cancers. Autophagy, which is a highly conserved lysosomal degradation process in eukaryotic cells, has been recently reported to be pos. regulated by SIRT3 in cancer; therefore, activating SIRT3-modulated autophagy may be a promising strategy for drug discovery. In this study, we discovered a small-mol. activator of SIRT3 compound 33c (ADTL-SA1215) with specific SIRT3 deacetylase activity by structure-guided design and high-throughput screening. Subsequently, compound 33c inhibited the proliferation and migration of human breast carcinoma MDA-MB-231 cells by SIRT3-driven autophagy/mitophagy signaling pathways in vitro and in vivo. Collectively, these results demonstrate that pharmacol. activation of SIRT3 is a potential therapeutic approach of triple neg. breast cancer (TNBC). More importantly, compound 33c may be a first-in-class specific small-mol. activator of SIRT3 that would be utilized for future cancer drug development. In the experimental materials used by the author, we found 3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7Electric Literature of C8H6Cl2O3)
