SDS of cas: 87-41-2. I found the field of Research & Experimental Medicine; Pharmacology & Pharmacy very interesting. Saw the article Enhancing insulin sensitivity by dual PPAR gamma partial agonist, beta-catenin inhibitor: Design, synthesis of new alpha phthalimido-o-toluoyl2-aminothiazole hybrids published in 2020, Reprint Addresses Mourad, AAE (corresponding author), Port Said Univ, Fac Pharm, Pharmacol & Toxicol Dept, Port Said, Egypt..

Aims: Partial PPAR gamma agonists attracted substantially heightened interest as safer thiazolidinediones alternatives. On the other hand, Wnt/beta-catenin antagonists have been highlighted as promising strategy for type 2 diabetes management via up-regulating PPAR gamma gene expression. We aimed at synthesizing novel partial PPAR gamma agonists with beta-catenin inhibitory activity which could enhance insulin sensitivity and avoid the side effects of full PPAR gamma agonists. Main methods: We synthesized novel series of alpha-phthlimido-o-toluoyl-2-aminothiazoles hybrids for evaluating their antidiabetic activity and discovering its mechanistic pathway. We assessed effect of the new hybrids on PPAR gamma activation using a luciferase reporter assay system. Moreover, intracellular triglyceride levels, gene levels of c/EBP alpha, PPAR gamma and PPAR gamma targets including GLUT4, adiponectin, aP2 were measured in 3T3-L1 cells. Uptake of 2-DOG together with PPAR gamma and beta-catenin protein levels were evaluated in 3T3-L1cells. In addition, molecular docking studies with PPAR gamma LBD, physicochemical properties and structure activity relationship of the novel hybrids were also studied. Key findings: Three of the synthesized hybrids showed partial PPAR gamma agonistic activity and distinct PPAR gamma binding pattern. These compounds modulated PPAR gamma gene expression and PPAR gamma target genes; and increased glucose uptake in 3T3-L1 and slightly induced adipogenesis compared to rosiglitazone. Moreover, these compounds reduced beta-catenin protein level which reflected in increased both PPAR gamma gene and protein levels that leads to improved insulin sensitivity and increased GLUT4 and adiponectin gene expression. Significance: Our synthesized compounds act as novel partial PPAR gamma agonists and beta-catenin inhibitors that have potent insulin sensitizing activity and mitigate the lipogenic side effects of TZDs.

Phthalides as the crucial core skeletons are found extensively in natural products and biological active molecules. Herein we disclose an asymmetric allylation of 3-hydroxyisoben-zofuran-1(3H)-ones with boron allylation reagents to construct chiral phthalide derivatives. The simple Bi(OAc)(3)/chiral phosphoric acid catalytic system proves to be efficient in this method, delivering the desired chiral 3-allylisobenzofuran-1(3H)-ones in good yields (up to 99%) and high enantioselectivities (up to 99.5:0.5 e.r.) under mild conditions. The large-scale reaction and diverse transformations of products to various scaffolds with potential biological activities render it more attractive. Moreover, the mechanism was preliminarily explored by control reactions, mass spectrometry, deuterium experiment, and DFT calculations.

For the metal-catalyzed asymmetric hydrogenation of alpha-substituted ketones, cis reductive products are generally obtained due to steric hindrance of substituents. Herein, an unprecedented trans reductive products were observed in palladium-catalyzed hydrogenative desymmetrization of cyclic and acyclic 1,3-diketones, providing the chiral trans beta-hydroxy ketones with two adjacent stereocenters including one alpha-tertiary or quaternary stereocenter with high enantioselectivity and diastereoselectivity. Mechanistic studies and DFT calculations suggested that the rarely observed diastereoselectivity reversal is ascribed to the charge-charge interaction between the palladium and aromatic ring of the substrate, which could not only result in the reversal of the diastereoselectivity, but also improve the reactivity.

A novel asymmetric phase-transfer-catalyzed gamma-alkylation of phthalide 3-carboxylic esters has been developed, giving access to 3,3-disubstituted phthalide derivatives, which present a chiral quaternary gamma-carbon in good to excellent yields and good enantioselectivities (74-88% ee). The enantiomeric purity could be substantially enhanced to 94-95% ee by recrystallization. Both electron-withdrawing and electron-releasing substituents are well tolerated on the phthalide core as well as on the aromatic moiety of the alkylating agent. This methodology, enabling the introduction of an unfunctionalized group at the phthalide gamma-position, fully complements previously reported organocatalytic strategies involving functionalized electrophiles, thus expanding the scope of accessible 3,3-disubstituted products. The high synthetic value of this asymmetric reaction has been proven by the formal synthesis of the naturally occurring alkaloid (+)-(9S,13R)-13-hydroxyisocyclocelabenzine.

Melanin is a natural pigment that is produced by filamentous fungi. In this study, the endophytic species, Spissiomyces endophytica (strain SDBR-CMU319), produced a brownblack pigment in the mycelia. Consequently, the pigment was extracted from the dried fungal biomass. This was followed by pigment purification, characterization and identification. Physical and chemical characteristics of the pigment showed acid precipitation, alkali solubilization, decolorization with oxidizing agents, and insolubility in most organic solvents and water. The pigment was confirmed as melanin based on ultraviolet-visible spectroscopy, Fourier-transform infrared, and electron paramagnetic resonance spectra analyses. The analyses of the elemental composition indicated that the pigment possessed a low percentage of nitrogen, and therefore, was not 3,4-dihydroxyphenylalanine melanin. Inhibition studies involving specific inhibitors, both tricyclazole and phthalide, and suggest that fungal melanin could be synthesized through the 1,8-dihydroxynaphthalene pathway. The optimum conditions for fungal pigment production from this species were investigated. The highest fungal pigment yield was observed in glucose yeast extract peptone medium at an initial pH value of 6.0 and at 25 degrees C over three weeks of cultivation. This is the first report on the production and characterization of melanin obtained from the genus Spissiomyces.

A great amount of insoluble phosphate in agricultural soils is not available for crops. Three strains of bacteria (Bacillus megaterium YLYP1 Pseudumonas prosekii YLYP6 and Pseudomonas sp. YLYP29) isolated from activated sludge and soil could efficiently solubilise tricalcium phosphate. In particular, the novel strain P. prosekii YLYP6 produced 716 mg L-1 of available phosphate within 6 days under the optimal culture conditions [20 degrees C, pH 7.9, inoculum size of 0.5% (v:v)] determined by response surface methodology. P. prosekii YLYP6 demonstrated efficient phosphate solubilisation in response to broad variations in pH (5-9) and temperature (15-35 degrees C). The phosphate solubilisation curves of the strains fit well with a first-order kinetic model (R-2 > 0.939), with a halt-life of 1.51-5.94 d for 5.0 g L-1 calcium phosphate. Continuous culture experiments combined with scanning electron microscopic observations and gas chromatography-mass spectrometry analysis revealed that 2,3-dimethylfumaric acid, gluconic and N-butyl-tert-butylamine that were produced by P. prosekii YLYP6 were responsible for phosphate solubilisation by supplying H+ ions and organic anions. Efficient phosphate solubilisation in actual soil by P. prosekii YLYP6 demonstrated the strong application potential to reduce the use of chemical P fertilisers and the resulting agricultural nonpoint pollution.
