In 2022,Kotipalli, Ramesh; Nagireddy, Attunuri; Reddy, Maddi Sridhar published an article in Organic & Biomolecular Chemistry. The title of the article was 《Palladium-catalyzed cyclizative cross coupling of ynone oximes with 2-haloaryl N-acrylamides for isoxazolyl indoline bis-heterocycles》.COA of Formula: C6H5ClIN The author mentioned the following in the article:

Herein, a dual-cyclizative coupling of ynone oxime ethers RC(=NOR1)CCR2 (R = Ph, furan-2-yl, 3,4,5-trimethoxyphenyl, etc.; R1 = Me, Bn; R2 = Ph, 6-methoxynaphthalen-2-yl, cyclohex-1-en-1-yl, phenanthren-9-yl, etc.) with acrylamides R3N(R4)C(O)C(CH2)R5 (R3 = 2-iodophenyl, 5-fluoro-2-iodophenyl, 2-bromophenyl, etc.; R4 = Me, Et; R5 = H, Me) for the synthesis of methylene-linked isoxazolyl 2-oxindoles I (R6 = H, 5-Et, 6-F, 5-Cl, etc.) was demonstrated. The cascade was triggered by a palladium(II)-catalyzed ynone oxime ether cyclization, which underwent a Heck-type coupling intercepted by an aryl iodide insertion. Control experiments were carried out to understand the mechanism. In the experimental materials used by the author, we found 4-Chloro-2-iodoaniline(cas: 63069-48-7COA of Formula: C6H5ClIN)

4-Chloro-2-iodoaniline(cas: 63069-48-7) belongs to anime. Amines can be classified according to the nature and number of substituents on nitrogen. Aliphatic amines contain only H and alkyl substituents. Aromatic amines have the nitrogen atom connected to an aromatic ring.Important amines include amino acids, biogenic amines, trimethylamine, and aniline. Inorganic derivatives of ammonia are also called amines, such as monochloramine (NClH2).COA of Formula: C6H5ClIN

In 2022,Fang, Yuying; Tan, Qingyun; Zhou, Huihao; Gu, Qiong; Xu, Jun published an article in European Journal of Medicinal Chemistry. The title of the article was 《Discovery of novel diphenylbutene derivative ferroptosis inhibitors as neuroprotective agents》.Electric Literature of C6H5IO The author mentioned the following in the article:

Herein, with phenotypic assays, a new diphenylbutene derivative ferroptosis inhibitor, DPT was discovered. Based on this hit, new diphenylbutene derivatives I [R1 = H, 2-OMe, 3-OH, etc.; R2 = H, 3-OH, 4-OH, etc.] synthesized via condensation of (piperazinyl)pyrimidine and (phenyl)-phenylpentadienoic acids II and evaluated their ferroptosis inhibitory activities in HT22 mouse hippocampal neuronal cells and found that three compounds exhibited improved inhibitory activities compared with DPT. Among these active compounds, compound I [R1 = 3-OMe-4-HOC6H4, R2 = H] displayed the most potent anti-ferroptosis activity (EC50 = 1.7μM). Further studies demonstrated that compound I [R1 = 3-OMe-4-HOC6H4, R2 = H] was a specific ferroptosis inhibitor. It was revealed that different than the classic ferroptosis inhibitors, compound I [R1 = 3-OMe-4-HOC6H4, R2 = H] blocked ferroptosis by increasing FSP1 protein level. Compound I [R1 = 3-OMe-4-HOC6H4, R2 = H] could penetrate blood-brain barrier (BBB). In a rat model of ischemic stroke, compound I [R1 = 3-OMe-4-HOC6H4, R2 = H] effectively mitigated cerebral ischemic injury. Therefore, it was confirmed that compound I [R1 = 3-OMe-4-HOC6H4, R2 = H] as a novel ferroptosis inhibitor with a new scaffold, was promising for further development as an agent against neurol. diseases. The experimental process involved the reaction of 3-Iodophenol(cas: 626-02-8Electric Literature of C6H5IO)

3-Iodophenol(cas: 626-02-8) belongs to organic iodides. Generally organic iodides can be divided into two classes of alkyl iodides and aryl iodides. Typical reactions of alkyl iodides include nucleophilic substitution, elimination, reduction, and the formation of organometallics.Electric Literature of C6H5IO

Application of 624-73-7In 2016 ,《Poly(paraphenylene sulfide) and Poly(metaphenylene sulfide) via Light-Initiated SRN1-Type Polymerization of Halogenated Thiophenols》 appeared in Macromolecular Rapid Communications. The author of the article were Heine, Niklas B.; Studer, Armido. The article conveys some information:

In this work, the synthesis of various halogenated thiophenol derivatives is presented. These thiophenols are used as monomers in light-initiated SRN1-type radical polymerization reactions. The method provides easy access to industrially relevant poly(paraphenylene sulfide) and poly(metaphenylene sulfide). The influence of the halide leaving group and of other substituents in the thiophenol monomer on the polymerization process is investigated. In addition to this study using 1,2-Diiodoethane, there are many other studies that have used 1,2-Diiodoethane(cas: 624-73-7Application of 624-73-7) was used in this study.

1,2-Diiodoethane(cas: 624-73-7) is one of organic iodides. The carbon-iodine bond is weaker than other carbon-halogen bonds due to the poor electronegative nature of the iodine atom. In general, organic iodides are light-sensitive and turn yellow during storage, owing to the formation of iodine. Organic iodides can be alkyl, alkenyl, or alkynyl, and all of them are very reactive toward with many kinds of nucleophiles.Application of 624-73-7

This example highlights the ability of supramol. systems to form topol. complex architectures using geometrically simple building blocks. In the part of experimental materials, we found many familiar compounds, such as 1-Bromo-4-iodobenzene(cas: 589-87-7Name: 1-Bromo-4-iodobenzene)

Application of 301673-14-3In 2022 ,《A Small-Molecule Oral Agonist of the Human Glucagon-like Peptide-1 Receptor》 was published in Journal of Medicinal Chemistry. The article was written by Griffith, David A.; Edmonds, David J.; Fortin, Jean-Philippe; Kalgutkar, Amit S.; Kuzmiski, J. Brent; Loria, Paula M.; Saxena, Aditi R.; Bagley, Scott W.; Buckeridge, Clare; Curto, John M.; Derksen, David R.; Dias, Joao M.; Griffor, Matthew C.; Han, Seungil; Jackson, V. Margaret; Landis, Margaret S.; Lettiere, Daniel; Limberakis, Chris; Liu, Yuhang; Mathiowetz, Alan M.; Patel, Jayesh C.; Piotrowski, David W.; Price, David A.; Ruggeri, Roger B.; Tess, David A.. The article contains the following contents:

Peptide agonists of the glucagon-like peptide-1 receptor (GLP-1R) have revolutionized diabetes therapy, but their use has been limited because they require injection. Herein, we describe the discovery of the orally bioavailable, small-mol., GLP-1R agonist PF-06882961 (danuglipron). A sensitized high-throughput screen was used to identify 5-fluoropyrimidine-based GLP-1R agonists that were optimized to promote endogenous GLP-1R signaling with nanomolar potency. Incorporation of a carboxylic acid moiety provided considerable GLP-1R potency gains with improved off-target pharmacol. and reduced metabolic clearance, ultimately resulting in the identification of danuglipron. Danuglipron increased insulin levels in primates but not rodents, which was explained by receptor mutagenesis studies and a cryogenic electron microscope structure that revealed a binding pocket requiring a primate-specific tryptophan 33 residue. Oral administration of danuglipron to healthy humans produced dose-proportional increases in systemic exposure (NCT03309241). This opens an opportunity for oral small-mol. therapies that target the well-validated GLP-1R for metabolic health.
