Florencia, Heinecke published the artcileThe offspring from rats fed a fatty diet display impairments in the activation of liver peroxisome proliferator activated receptor alpha and features of fatty liver disease, Formula: C12H15ClO3, the publication is Molecular and Cellular Endocrinology (2020), 110818, database is CAplus and MEDLINE.

Maternal obesity programs liver derangements similar to those of NAFLD. Our main goal was to evaluate whether these liver anomalies were related to aberrant PPARα function. Obesity was induced in female Albino-Wistar rats by a fatty diet (FD rats). Several parameters related to NAFLD were evaluated in both plasma and livers from fetuses of 21 days of gestation and 140-day-old offspring. FD fetuses and offspring developed increased levels of AST and ALT, signs of inflammation and oxidative and nitrative stress-related damage. FD offspring showed dysregulation of Plin2, CD36, Cyp4A, Aco, Cpt-1, Hadha and Acaa2 mRNA levels, genes involved in lipid metabolism and no catabolic effect of the PPARα agonist clofibrate. These results suggest that the FD offspring is prone to develop fatty liver, a susceptibility that can be linked to PPARα dysfunction, and that this could in turn be related to the liver impairments programmed by maternal obesity.

Shchetinina, V. N. published the artcileEffect of decamethoxine on the integrity of cytoplasmic membranes of gram-positive and gram-negative microorganisms, Name: N1,N10-Bis(2-((2-isopropyl-5-methylcyclohexyl)oxy)-2-oxoethyl)-N1,N1,N10,N10-tetramethyldecane-1,10-diaminium chloride, the publication is Mikrobiologicheskii Zhurnal (1978-1993) (1990), 52(3), 24-8, database is CAplus.

Decamethoxine increased the membrane permeability of Pseudomonas aeruginosa, Escherichia coli, and Micrococcus lysodeikticus. Viability decreased and dehydrogenase activity was inhibited. Aspartate and alanine aminotransferases were not inhibited by decamethoxine, and activity even increased. Decamethoxine lysed the protoplasts of these bacteria. At high decamethoxine concentrations (>500 μg/mL for P. aeruginosa and >200 μ/mL for E. coli) the outflow of components from these gram-neg. bacteria ceased; this may be associated with coagulation changes in the cytoplasm. Loss of low-mol. components by M. lysodeikticus cells and protoplast lysis were less than in the gram-neg. microorganisms, explained by less resistance of M. lysodeikticus to decamethoxine and earlier coagulation of the cytoplasm, preventing lysis.

van Dijken, Derk Jan published the artcileAutoamplification of Molecular Chirality through the Induction of Supramolecular Chirality, Category: chlorides-buliding-blocks, the publication is Angewandte Chemie, International Edition (2014), 53(20), 5073-5077, database is CAplus and MEDLINE.

The novel concept for the autoamplification of mol. chirality, wherein the amplification proceeds through the induction of supramol. chirality, is presented. A solution of prochiral, ring-open diarylethenes is doped with a small amount of their chiral, ring-closed counterpart. The mols. co-assemble into helical fibers through hydrogen bonding and the handedness of the fibers is biased by the chiral, ring-closed diarylethene. Photochem. ring closure of the open diarylethene yields the ring-closed product, which is enriched in the template enantiomer.

De, Kakali published the artcileRadiolabeled novel peptide for imaging somatostatin receptor-expressing tumor: synthesis and radiobiological evaluation, Synthetic Route of 42074-68-0, the publication is Journal of Radioanalytical and Nuclear Chemistry (2014), 301(3), 847-861, database is CAplus.

The aim of this study was to synthesis, a radiolabeled (^99mTc) new somatostatin-analog 6-hydrazinopyridine-3-carboxylic-acid (HYNIC)-Asn³-octreotate (^99mTc-HYNIC-AATE), and to evaluate as a candidate for imaging somatostatin-receptor (SSTR)-pos. tumors and also compare it with ^99mTc-HYNIC-Tyr³-octreotide (^99mTc-HYNIC-TOC). Synthesis was performed by Fmoc-solid-phase strategy and ^99mTc labeled by SnCl₂. Biodistribution and imaging properties of new radiopeptide were also studied in C6 tumor bearing rat. Radiolabeling was performed at high specific activities and it showed high binding-affinity for SSTR2. In biodistribution, radiopeptides have showed high and receptor-specific uptake in the SSTR2 pos. organs, tumor with rapid renal excretion from non-target tissues. These results demonstrated that ^99mTc-HYNIC-AATE is a new specific radioligand for scintigraphy of somatostatin-receptor-pos. tumors.

Ruiz, Patricia published the artcilePrediction of acute mammalian toxicity using QSAR methods: a case study of Sulfur Mustard and its breakdown products, Application In Synthesis of 1002-41-1, the publication is Molecules (2012), 8982-9001, database is CAplus and MEDLINE.

Predicting toxicity quant., using Quant. Structure Activity Relationships (QSAR), has matured over recent years to the point that the predictions can be used to help identify missing comparison values in a substance’s database. In this manuscript we investigate using the LD that kills 50% of a test population (the LD₅₀) for determining relative toxicity of a number of substances. In general, the smaller the LD₅₀ value, the more toxic the chem., and the larger the LD₅₀ value, the lower the toxicity. When systemic toxicity and other specific toxicity data are unavailable for the chem.(s) of interest, during emergency responses, LD₅₀ values may be employed to determine the relative toxicity of a series of chems. In the present study, a group of chem. warfare agents and their breakdown products were evaluated using 4 available rat oral QSAR LD₅₀ models. The QSAR anal. shows that the breakdown products of Sulfur Mustard (HD) are predicted to be less toxic than the parent compound as well as other known breakdown products that have known toxicities. The QSAR estimated break down products LD₅₀ values ranged from 299 mg/kg to 5,764 mg/kg. This evaluation allows for the ranking and toxicity estimation of compounds for which little toxicity information existed; thus leading to better risk decision making in the field.

Baldwin, Jack E. published the artcile5-Isothiazolidinonyl and 5-isoxazolidinonyl radicals. Approaches to the biogenetic-type synthesis of β-lactams, SDS of cas: 18791-02-1, the publication is Tetrahedron (1981), 37(11), 2181-9, database is CAplus.

A possible mechanism for penicillin biosynthesis involves the rearrangement of a 5-isothiazolidinonyl radical I [R = NHCO(CH₂)₃CH(N⁺H₃)CO₂^–, R¹ = H, R² = CH(CO₂H)CHMe₂] to a β-lactam. However, the model radicals I (R = R¹ = Ph, R² = CMe₃; R = Br₃C, R¹ = H, R² = CMe₃), generated in the conversion of II (R = Br, R¹ = R² = Ph) to II (R = H, R¹, R² as before) and II (RR¹ = bond, R² = H) to II (RR¹ = bond, R² = Br₃C), resp., failed to give β-lactams. The analogous reaction of a 5-isoxazolidinonyl radical is the basis for a potential synthesis of clavulanic acid, but again the rearrangement was not observed in the model radical III (R = H, R¹ = absent) generated in the conversion of III (R = H, R¹ = CO₂OCMe₃) to III (RR¹ = bond).

Gramstad, Thor published the artcileNMR Studies of hydrogen bonding of phenol with several proton acceptors, Recommanded Product: Diethyltrichloromethylphosphonate, the publication is Journal of Molecular Structure (1970), 5(4), 253-61, database is CAplus.

PMR studies are reported of self-association of PhOH in CCl4 and in cyclohexane, and of H bonding between PhOH and 2 carbonyl and several phosphoryl compounds The NMR chem. shift, δx, of a proton in a H bond is dependent on both the temperature and the concentration of the proton acceptor. Furthermore, the chem. shift data at low concentration of proton acceptor suggest the presence of a 2:1 proton donor-acceptor complex in addition to a 1:1 complex. A linear relation exists between the change in chem. shift and O-H stretching frequency shift upon complexation of PhOH with phosphoryl compounds

Fox, Brian M. published the artcileA Selective Prostaglandin E₂ Receptor Subtype 2 (EP2) Antagonist Increases the Macrophage-Mediated Clearance of Amyloid-Beta Plaques, Product Details of C7H4BrClO2, the publication is Journal of Medicinal Chemistry (2015), 58(13), 5256-5273, database is CAplus and MEDLINE.

A high-throughput screen resulted in the discovery of benzoxazepine I, an EP2 antagonist possessing low microsomal stability and potent CYP3A4 inhibition. Modular optimization of lead compound I resulted in the discovery of benzoxazepine II, a mol. with single-digit nM binding affinity for the EP2 receptor and significantly improved microsomal stability. It was devoid of CYP inhibition and was ∼4000-fold selective against the other EP receptors. Compound II was shown to have good PK properties in CD-1 mice and high CNS permeability in C57Bl/6s mice and Sprague-Dawley rats. In an ex vivo assay, it demonstrated the ability to increase the macrophage-mediated clearance of amyloid-beta plaques from brain slices in a dose-dependent manner.
