Specificity of chem. structures and stereoisomers among serum-borne short-chain organic acids in rats were assessed for their effects on feeding behavior and humoral factors by infusion into the rat 3rd cerebroventricle. Infusion of glyceric acid (1.0 μmol), 3,4-dihydroxybutanoic acid γ-lactone (3,4-DB), or 3,4,5-trihydroxypentanoic acid γ-lactone (2.50 μmol) immediately before the dark phase decreased food intake for, at most, 24 h. These acids did not affect drinking or ambulation. Initial feeding, not necessarily accompanied by periprandial drinking, was induced after infusion of 2,4-dihydroxy-butanoic acid γ-lactone, 2,4,5-trihydroxypentanoic acid γ-lactone (2,4,5-TP), or exogenous 2,4,5,6-tetrahydroxyhexanoic acid γ-lactone (2.50 μmol) in the light phase. Of these acids, 3,4-DB most potently suppressed and 2,4,5-TP most potently enhanced feeding. Of these, the 2S,4S-isomer and the 3S-isomer were the most potent of 2,4,5-TP and 3,4-DB, resp. Only the 2S,4S-isomer of 2,4,5-TP induced hypoglycemia with hyperinsulinemia, whereas opposite effects were produced by the 3S-isomer of 3,4-DB. The positions of the hydroxyl groups on 4-butanolide and the S- and S,S-stereoisomers are important in modulating food intake through the hypothalamus.

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 Synthesis of nature product kinsenoside analogues with anti-inflammatory activity, published in 2021-01-01, which mentions a compound: 58081-05-3, Name is (R)-4-Hydroxydihydrofuran-2(3H)-one, Molecular C4H6O3, Formula: C4H6O3.

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.

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.

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 First identification of boronic species as novel potential inhibitors of the Staphylococcus aureus NorA efflux pump, published in 2014-03-27, which mentions a compound: 59782-89-7, Name is 2-Chloro-5-iodo-3-methylpyridine, Molecular C6H5ClIN, SDS of cas: 59782-89-7.

Overexpression of efflux pumps is an important mechanism of bacterial resistance that results in the extrusion of antimicrobial agents outside the bacterial cell. Inhibition of such pumps appears to be a promising strategy that could restore the potency of existing antibiotics. The NorA efflux pump of Staphylococcus aureus confers resistance to a wide range of unrelated substrates, such as hydrophilic fluoroquinolones, leading to a multidrug-resistance phenotype. Here, 150 heterocyclic boronic species were evaluated for their activity against susceptible and resistant strains of S. aureus. Twenty-four hit compounds, although inactive when tested alone, were found to potentiate ciprofloxacin activity by a 4-fold increase at concentrations ranging from 0.5 to 8 μg/mL against S. aureus 1199B, which overexpresses NorA. Boron-free analogs showed no biol. activity, thus revealing that the boron atom is crucial for biol. activity. This work describes the first reported efflux pump inhibitory activity of boronic acid derivatives

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.

The three-dimensional configuration of the ester heterocycle is basically the same as that of the carbocycle. Compound: 4-Methoxypiperidine(SMILESS: COC1CCNCC1,cas:4045-24-3) is researched.Product Details of 56413-95-7. 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.
