The article was 《Discovery of Brain-Penetrant Glucosylceramide Synthase Inhibitors with a Novel Pharmacophore》. The article mentions the following:

Inhibition of glucosylceramide synthase (GCS) is a major therapeutic strategy for Gaucher’s disease and has been suggested as a potential target for treating Parkinson’s disease. Herein, authors report the discovery of novel brain-penetrant GCS inhibitors. Assessment of the structure-activity relationship revealed a unique pharmacophore in this series. The lipophilic ortho-substituent of aromatic ring A and the appropriate directionality of aromatic ring B were key for potency. Optimization of the absorption, distribution, metabolism, elimination, toxicity (ADMETox) profile resulted in the discovery of T-036, a potent GCS inhibitor in vivo. Pharmacophore-based scaffold hopping was performed to mitigate safety concerns associated with I. The ring opening of I resulted in another potent GCS inhibitor with a lower toxicol. risk, II, which reduced glucosylceramide in a dose-dependent manner in the plasma and cortex of mice. Finally, authors discuss the structural aspects of the compounds that impart a unique inhibition mode and lower the cardiovascular risk. In the experiment, the researchers used many compounds, for example, 2-Chloroisonicotinic acid(cas: 6313-54-8Recommanded Product: 2-Chloroisonicotinic acid)

And the article was published in Science (Washington, DC, United States) in 2021. Safety of 2-Chloroisonicotinic acid The author mentioned the following in the article:

Hydroxylation of aryl carbon-hydrogen bonds with transition metal catalysts has proven challenging when oxygen is used as the oxidant. Here, we report a palladium complex bearing a bidentate pyridine/pyridone ligand that efficiently catalyzes this reaction at ring positions adjacent to carboxylic acids. IR, x-ray, and computational anal. support a possible role of ligand tautomerization from mono-anionic (L,X) to neutral (L,L) coordination in the catalytic cycle of aerobic carbon-hydrogen hydroxylation reaction. The conventional site selectivity dictated by heterocycles is overturned by this catalyst, thus allowing late-stage modification of compounds of pharmaceutical interest at previously inaccessible sites. In addition to this study using 2-Chloroisonicotinic acid, there are many other studies that have used 2-Chloroisonicotinic acid(cas: 6313-54-8Safety of 2-Chloroisonicotinic acid) was used in this study.

A set of forty-six 6,7,10-trimethoxy-α-naphthoflavone derivatives I [R = 2-furyl, 2-chloro-4-pyridyl, 5-bromo-2-pyridyl, etc.] was synthesized and screened against CYP1 enzymes, leading to the identification of fluorine-containing compound I [R = 5-bromo-2-pyridyl] as the most potent and selective CYP1B1 inhibitor (IC50 value of 0.07 nM), being 84-fold more potent than that of the template mol. ANF. Alternatively, the amino-substituted derivative I [R = 4-amino-3-pyridyl] not only possessed a potent inhibitory effect on CYP1B1 (IC50 value of 0.98 nM), but also had a substantially increased water solubility as compared with the lead ANF. The current study expanded the structural diversity of CYP1B1 inhibitors and compound I [R = 4-amino-3-pyridyl] could be considered as a promising starting point with great potential for further studies.

An efficient and broadly applicable palladium-catalyzed iodination of inexpensive and abundant aryl and vinyl carboxylic acids via in situ activation to the acid chloride and formation of a phosphonium salt is reported.

Eaton, John K.; Furst, Laura; Cai, Luke L.; Viswanathan, Vasanthi S.; Schreiber, Stuart L. published their research in Bioorganic & Medicinal Chemistry Letters on December 1 ,2020. The article was titled 《Structure-activity relationships of GPX4 inhibitor warheads》.Reference of 2-Chloroisonicotinic acid The article contains the following contents:

Direct inhibition of GPX4 requires covalent modification of the active-site selenocysteine. While phenotypic screening has revealed that activated alkyl chlorides and masked nitrile oxides can inhibit GPX4 covalently, a systematic assessment of potential electrophilic warheads with the capacity to inhibit cellular GPX4 has been lacking. Here, we survey more than 25 electrophilic warheads across several distinct GPX4-targeting scaffolds. We find that electrophiles with attenuated reactivity compared to chloroacetamides are unable to inhibit GPX4 despite the expected nucleophilicity of the selenocysteine residue. However, highly reactive propiolamides we uncover in this study can substitute for chloroacetamide and nitroisoxazole warheads in GPX4 inhibitors. Our observations suggest that electrophile masking strategies, including those we describe for propiolamide- and nitrile-oxide-based warheads, may be promising for the development of improved covalent GPX4 inhibitors. In the part of experimental materials, we found many familiar compounds, such as 2-Chloroisonicotinic acid(cas: 6313-54-8Reference of 2-Chloroisonicotinic acid)

Related Products of 6313-54-8On May 11, 2022 ,《Unified Approach to Decarboxylative Halogenation of (Hetero)aryl Carboxylic Acids》 appeared in Journal of the American Chemical Society. The author of the article were Chen, Tiffany Q.; Pedersen, P. Scott; Dow, Nathan W.; Fayad, Remi; Hauke, Cory E.; Rosko, Michael C.; Danilov, Evgeny O.; Blakemore, David C.; Dechert-Schmitt, Anne-Marie; Knauber, Thomas; Castellano, Felix N.; MacMillan, David W. C.. The article conveys some information:

A general catalytic method for direct decarboxylative halogenation of (hetero)aryl carboxylic acids RC(O)OH (R = 4-sulfamoylphenyl, 5-methylpyridin-2-yl, isoquinolin-1-yl, etc.) via ligand-to-metal charge transfer was reported. This strategy accommodates an exceptionally broad scope of substrates. An aryl radical intermediate is leveraged toward divergent functionalization pathways: (1) atom transfer to access bromo- or iodo(hetero)arenes or (2) radical capture by copper and subsequent reductive elimination to generate chloro- or fluoro(hetero)arenes. The proposed ligand-to-metal charge transfer mechanism is supported through an array of spectroscopic studies.2-Chloroisonicotinic acid(cas: 6313-54-8Related Products of 6313-54-8) was used in this study.
