In 2019,Chemical & Pharmaceutical Bulletin included an article by Togo, Takaya; Sohma, Youhei; Kuninobu, Yoichiro; Kanai, Motomu. COA of Formula: C6H6BrN. The article was titled 《Palladium-catalyzed C-H heteroarylation of 2,5-disubstituted imidazoles》. The information in the text is summarized as follows:

A palladium-catalyzed C-H N-heteroarylation of N-protected-2,5-disubstituted imidazoles at the C4-position using N-heteroaryl halides as a coupling partner was developed. Intensive reaction condition screening led to identify fluorinated bathophenanthroline as the optimum ligand for the palladium catalyst. This reaction enhanced optimization of drug candidates by facilitating the synthesis of heterobiaryl compounds containing an imidazole ring. In the experimental materials used by the author, we found 2-Bromo-5-methylpyridine(cas: 3510-66-5COA of Formula: C6H6BrN)

2-Bromo-5-methylpyridine(cas: 3510-66-5) belongs to pyridine. Pyridine is very deactivated towards electrophilic substitution with respect to benzene. For this reason classical formylation, using methods such as the Gattermann or Vilsmeier reactions, are not generally successful. COA of Formula: C6H6BrN

And the article was published in Chemistry – A European Journal in 2019. Reference of 2-Bromo-5-methylpyridine The author mentioned the following in the article:

An organoruthenium(II) complex with pyrithione (2-mercaptopyridine N-oxide) 1 a has previously been identified by our group as a compound with promising anticancer potential without cytotoxicity towards non-cancerous cells. To expand the rather limited research on compounds of this type, an array of novel chlorido and 1,3,5-triaza-7-phosphaadamantane (pta) organoruthenium(II) complexes with methyl-substituted pyrithiones has been prepared After thorough investigation of the aqueous stability of these complexes, their modes of action have been elucidated at the cellular level. Minor structural alterations in the ruthenium-pyrithionato compounds resulted in fine-tuning of their cytotoxicities. The best performing compounds, 1 b and 2 b, with a chlorido or pta ligand bound to ruthenium, resp., and a Me group at the 3-position of the pyrithione scaffold, have been further investigated. Both compounds trigger early apoptosis, induce the generation of reactive oxygen species and G1 arrest in A549 cancer cells, and show no strong interaction with DNA. However, only 1 b also inhibits thioredoxin reductase. Wound healing assays and mitochondrial function evaluation have revealed differences between these two compounds at the cellular level. In the part of experimental materials, we found many familiar compounds, such as 2-Bromo-5-methylpyridine(cas: 3510-66-5Reference of 2-Bromo-5-methylpyridine)

2-Bromo-5-methylpyridine(cas: 3510-66-5) belongs to pyridine. When pyridine is adsorbed on oxide surfaces or in porous materials, the following species are commonly observed: (i) pyridine coordinated to Lewis acid sites, (ii) pyridine H-bonded to weakly acidic hydroxyls, and (iii) protonated pyridine. At high coverage, physisorbed pyridine and protonated dimers can also be observed.Reference of 2-Bromo-5-methylpyridine

The 2-benzylpyridines scaffolds I (R = 4-Me, 3-Cl, 2-trifluoromethyl, etc.) have been found in various drugs, bioactive natural products, and medicinally important compounds This manuscript comprises the synthesis of various fluorinated analogs of 2-benzylpyridine compounds I by using a Negishi coupling reaction as a key reaction. In the experiment, the researchers used many compounds, for example, 2-Bromo-5-methylpyridine(cas: 3510-66-5Application In Synthesis of 2-Bromo-5-methylpyridine)

2-Bromo-5-methylpyridine(cas: 3510-66-5) belongs to pyridine. Pyridine’s structure is isoelectronic with that of benzene, but its properties are quite different. Pyridine is completely miscible with water, whereas benzene is only slightly soluble. Like all hydrocarbons, benzene is neutral (in the acid–base sense), but because of its nitrogen atom, pyridine is a weak base.Application In Synthesis of 2-Bromo-5-methylpyridine

Recommanded Product: 3510-66-5In 2021 ,《A study of the structure-affinity relationship in SYA16263; is a D2 receptor interaction essential for inhibition of apormorphine-induced climbing behavior in mice?》 appeared in Bioorganic & Medicinal Chemistry. The author of the article were Onyameh, Edem K.; Bricker, Barbara A.; Eyunni, Suresh V. K.; Voshavar, Chandrashekhar; Gonela, Uma M.; Ofori, Edward; Jenkins, Andrea; Ablordeppey, Seth Y.. The article conveys some information:

Dopamine (DA) and serotonin (5-HT) receptors are prime targets for the development of antipsychotics. The specific role of each receptor subtype to the pharmacol. effects of antipsychotic drugs remains unclear. Understanding the relationship between antipsychotic drugs and their binding affinities at DA and 5-HT receptor subtypes is very important for antipsychotic drug discovery and could lead to new drugs with enhanced efficacies. We have previously disclosed SYA16263 (5) as an interesting compound with moderate radioligand binding affinity at the D2 & D3 receptors (Ki = 124 nM & 86 nM resp.) and high binding affinities towards D4 and 5-HT1A receptors (Ki = 3.5 nM & 1.1 nM resp.). Furthermore, we have demonstrated SYA16263 (5) is functionally selective and produces antipsychotic-like behavior but without inducing catalepsy in mice. Based on its pharmacol. profile, we selected SYA16263 (5) to study its structure-affinity relationship with a view to obtaining new analogs that display receptor subtype selectivity. In this study, we present the synthesis of structurally modified SYA16263 (5) analogs and their receptor binding affinities at the DA and 5-HT receptor subtypes associated with antipsychotic action. Furthermore, we have identified compound 21 with no significant binding affinity at the D2 receptor subtype but with moderate binding affinity at the D3 and D4 receptors subtypes. However, because 21 is able to demonstrate antipsychotic-like activity in a preliminary test, using the reversal of apomorphine-induced climbing behavior experiment in mice with SYA16263 and haloperidol as pos. controls, we question the essential need of the D2 receptor subtype in reversing apomorphine-induced climbing behavior. In the experiment, the researchers used many compounds, for example, 2-Bromo-5-methylpyridine(cas: 3510-66-5Recommanded Product: 3510-66-5)

Product Details of 3510-66-5In 2020 ,《Sulfur(IV)-Mediated Unsymmetrical Heterocycle Cross-Couplings》 was published in Angewandte Chemie, International Edition. The article was written by Zhou, Min; Tsien, Jet; Qin, Tian. The article contains the following contents:

Despite the tremendous utilities of metal-mediated cross-couplings in modern organic chem., coupling reactions involving nitrogenous heteroarenes remain a challenging undertaking – coordination of Lewis basic atoms into metal centers often necessitate elevated temperature, high catalyst loading, etc. Herein, the authors report a sulfur (IV) mediated cross-coupling amendable for the efficient synthesis of heteroaromatic substrates. Addition of heteroaryl nucleophiles to a simple, readily-accessible alkyl sulfinyl (IV) chloride gave a trigonal bipyramidal sulfurane intermediate. Reductive elimination therefrom provides bis-heteroaryl products in a practical and efficient fashion.

The author of the article were Mohanty, Smruti Ranjan; Prusty, Namrata; Gupta, Lokesh; Biswal, Pragati; Ravikumar, Ponneri Chandrababu. The article conveys some information:

Co(III)-catalyzed alkenylation of 2-pyridones by using terminal alkyne as a reaction partner with high regioselectivity has been demonstrated for the first time. The reaction conditions are mild and compatible with a wide range of substrate combinations. It also shows good functional group tolerance. It proceeds through cyclometalation followed by alkyne insertion and protodemetalation steps. The formation of five- and seven-membered cobaltacycle intermediates was also detected through high-resolution mass spectrometry. The results came from multiple reactions, including the reaction of 2-Bromo-5-methylpyridine(cas: 3510-66-5Application of 3510-66-5)

In 2019,Journal of the American Chemical Society included an article by Liu, Kanglei; Lalancette, Roger A.; Jakle, Frieder. Computed Properties of C6H6BrN. The article was titled 《Tuning the Structure and Electronic Properties of B-N Fused Dipyridylanthracene and Implications on the Self-Sensitized Reactivity with Singlet Oxygen》. The information in the text is summarized as follows:

We demonstrate that the modification of anthracene with B ← N Lewis pairs at their periphery serves as a highly effective tool to modify the electronic structure with important ramifications on the generation and reactivity toward singlet oxygen. A series of BN-fused dipyridylanthracenes with Me groups in different positions of the pyridyl ring have been prepared via directed electrophilic borylation. The steric and electronic effects of the substituents on the structural features and electronic properties of the isomeric borane-functionalized products have been investigated in detail, aided by exptl. tools and computational studies. We find that BDPA-2Me, with Me groups adjacent to the pyridyl N, has the longest B-N distance and shows overall less structural distortions, whereas BDPA-5Me with the Me group close to the anthracene backbone experiences severe distortions that are reflected in the buckling of the anthracene framework and dislocation of the boron atoms from the planes of the Ph rings they are attached to. The substitution pattern also has a dramatic effect on the self-sensitized reactivity of the acenes toward O2 and the thermal release of singlet oxygen from the resp. endoperoxides. Kinetic analyses reveal that BDPA-2Me rapidly reacts with O2, whereas BDPA-5Me is converted only very slowly to its endoperoxide. However, the latter serves as an effective singlet oxygen sensitizer, as demonstrated in the preferential formation of the endoperoxide of dimethylanthracene in a competition experiment These results demonstrate that even relatively small modifications in the substitution of the pyridyl ring of BN-fused dipyridylanthracenes change the steric and electronic structure, resulting in dramatically different reactivity patterns. Our findings provide important guidelines for the design of highly effective sensitizers for singlet oxygen on one hand and the realization of materials that readily form endoperoxides in a self-sensitized manner and then thermally release singlet oxygen on demand on the other hand. The experimental part of the paper was very detailed, including the reaction process of 2-Bromo-5-methylpyridine(cas: 3510-66-5Computed Properties of C6H6BrN)
