Quality Control of 4-Chloro-2-fluoropyridine. The protonation of heteroatoms in aromatic heterocycles can be divided into two categories: lone pairs of electrons are in the aromatic ring conjugated system; and lone pairs of electrons do not participate. Compound: 4-Chloro-2-fluoropyridine, is researched, Molecular C5H3ClFN, CAS is 34941-92-9, about Native functionality in triple catalytic cross-coupling: sp3 C-H bonds as latent nucleophiles. Author is Shaw, Megan H.; Shurtleff, Valerie W.; Terrett, Jack A.; Cuthbertson, James D.; MacMillan, David W. C..

The use of sp3 C-H bonds-which are ubiquitous in organic mols.-as latent nucleophile equivalent for transition metal-catalyzed cross-coupling reactions has the potential to substantially streamline synthetic efforts in organic chem. while bypassing substrate activation steps. Through the combination of photoredox-mediated hydrogen atom transfer (HAT) and nickel catalysis, we have developed a highly selective and general C-H arylation protocol that activates a wide array of C-H bonds as native functional handles for cross-coupling. This mild approach takes advantage of a tunable HAT catalyst that exhibits predictable reactivity patterns based on enthalpic and bond polarity considerations to selectively functionalize α-amino and α-oxy sp3 C-H bonds in both cyclic and acyclic systems.

The article 《Discovery of Novel Thiophene-arylamide Derivatives as DprE1 Inhibitors with Potent Antimycobacterial Activities》 in relation to this compound, is published in Journal of Medicinal Chemistry. Let’s take a look at the latest research on this compound (cas:4045-24-3).

In this study, we report the design and synthesis of a series of novel thiophene-arylamide compounds derived from the noncovalent decaprenylphosphoryl-β-D-ribose 2′-epimerase (DprE1) inhibitor TCA1 through a structure-based scaffold hopping strategy. Systematic optimization of the two side chains flanking the thiophene core led to new lead compounds bearing a thiophene-arylamide scaffold with potent antimycobacterial activity and low cytotoxicity. Compounds I, II, III [X = H,F] exhibited potent in vitro activity against both drug-susceptible (min. inhibitory concentration (MIC) = 0.02-0.12μg/mL) and drug-resistant (MIC = 0.031-0.24μg/mL) tuberculosis strains while retaining potent DprE1 inhibition (half maximal inhibitory concentration (IC50) = 0.2-0.9μg/mL) and good intracellular antimycobacterial activity. In addition, these compounds showed good hepatocyte stability and low inhibition of the human ether-á-go-go related gene (hERG) channel. The representative compound III [X = H] with acceptable pharmacokinetic property demonstrated significant bactericidal activity in an acute mouse model of tuberculosis. Moreover, the mol. docking study of template compound I provides new insight into the discovery of novel antitubercular agents targeting DprE1.

Formula: C6H13NO. So far, in addition to halogen atoms, other non-metallic atoms can become part of the aromatic heterocycle, and the target ring system is still aromatic. Compound: 4-Methoxypiperidine, is researched, Molecular C6H13NO, CAS is 4045-24-3, about Identification of thiophene-benzenesulfonamide derivatives for the treatment of multidrug-resistant tuberculosis.

A series of thiophene-benzenesulfonamide derivatives was designed and synthesized by exploring the structure-activity relationship of lead compounds 2,3-disubstituted thiophenes I and 297F II as antituberculosis agents, which displayed potent antimycobacterial activity against drug-susceptible and clin. isolated drug-resistant tuberculosis. In particular, compound III (-R1R2- = -(CH2)4-), which had improved activity (min. inhibitory concentration of 0.023 μg/mL) compared with the lead compounds, displayed good intracellular antimycobacterial activity in macrophages with a reduction of 1.29 log10 CFU. A druggability evaluation indicated that compound III (-R1R2- = -(CH2)4-) had favorable hepatocyte stability, low cytotoxicity, and low hERG channel inhibition. Moreover, compound III (-R1R2- = -(CH2)4-) exhibited modest in vivo efficacy in an acute mouse model of tuberculosis. In addition, the mol. docking study elucidated the binding mode of compound III (-R1R2- = -(CH2)4-) in the active site of DprE1. Therefore, compound III (-R1R2- = -(CH2)4-) may be a promising antituberculosis lead for further research.

In general, if the atoms that make up the ring contain heteroatoms, such rings become heterocycles, and organic compounds containing heterocycles are called heterocyclic compounds. An article called Discovery of new thieno[2,3-d]pyrimidine and thiazolo[5,4-d]pyrimidine derivatives as orally active phosphoinositide 3-kinase inhibitors, published in 2021-01-01, which mentions a compound: 4045-24-3, Name is 4-Methoxypiperidine, Molecular C6H13NO, Reference of 4-Methoxypiperidine.

As abnormal PI3K signaling is a feature of many types of cancer, the development of orally active PI3K inhibitors is of great significance for targeted cancer therapy. Through integrating strategies of reducing aromatic character/increasing the fraction of sp3 carbons together with scaffold hopping, we designed and synthesized two new series of thieno[2,3-d]pyrimidine and thiazolo[5,4-d]pyrimidine derivatives for use as PI3K inhibitors. Our structure-activity relationship studies led to the identification of thieno[2,3-d]pyrimidine 6a and thiazolo[5,4-d]pyrimidine 7a (I and II, resp.), which exhibited remarkable nanomolar PI3K potency, good antiproliferative activity, favorable pharmacokinetic properties and significant in vivo anti-cancer efficacy. Notably, thiazolo[5,4-d]pyrimidine 7a had better anti-cancer activity than thieno[2,3-d]pyrimidine 6a and is worthy of further pre-clin. evaluation for its use in cancer treatment.

Kinsenoside (I) is a major bioactive component in herbal medicines that possesses a broad range of pharmacol. functions. Goodyeroside A (II), an epimer of kinsenoside, remains less explored. In this report, the authors chem. synthesized kinsenoside, goodyeroside A and their analogs with glycan variation, chirality inversion at chiral center(s), and bioisosteric replacement of lactone with lactam. Among these compounds, goodyeroside A and its mannosyl counterpart III demonstrated superior anti-inflammatory efficacy. Furthermore, goodyeroside A was found to suppress inflammation through inhibiting the NF-κB signal pathway effectively. The structure-activity relationship is also explored for further development of more promising kinsenoside analogs as drug candidates.
