Ravu, Ranga Rao; Jacob, Melissa R.; Khan, Shabana I.; Wang, Mei; Cao, Liang; Agarwal, Ameeta K.; Clark, Alice M.; Li, Xing-Cong published the artcile< Synthesis and Antifungal Activity Evaluation of Phloeodictine Analogues>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is phloeodictine analog preparation antifungal cytotoxicity structure activity relationship alkylation.

The phloeodictine-based 6-hydroxy-2,3,4,6-tetrahydropyrrolo[1,2-a]pyrimidinium structural moiety with an n-tetradecyl side chain at C-6 has been demonstrated to be a new antifungal template. Thirty-four new synthetic analogs with modifications of the bicyclic tetrahydropyrrolopyrimidinium skeleton and the N-1 side chain have been prepared and evaluated for in vitro antifungal activities against the clin. important fungal pathogens including Cryptococcus neoformans ATCC 90113, Candida albicans ATCC 90028, Candida glabrata ATCC 90030, Candida krusei ATCC 6258, and Aspergillus fumigatus ATCC 90906. Nineteen compounds showed antifungal activities against the aforementioned five fungal pathogens with min. inhibitory concentrations (MICs) in the range 0.88-10渭M, and all were fungicidal with min. fungicidal concentrations (MFCs) similar to the resp. MIC values. Three compounds were especially active against C. neoformans ATCC 90113 with MIC/MFC values of 1.0/1.0, 1.6/1.6, and 1.3/2.0渭M but exhibited low cytotoxicity with an IC50 > 40渭M against the mammalian Vero cells. The structure and antifungal activity relationship indicates that synthetic modifications of the phloeodictines can afford analogs with potent antifungal activity and reduced cytotoxicity, necessitating further preclin. studies of this new class of antifungal compounds

Alazet, Sebastien; Le Vaillant, Franck; Nicolai, Stefano; Courant, Thibaut; Waser, Jerome published the artcile< Divergent Access to (1,1) and (1,2)-Azidolactones from Alkenes using Hypervalent Iodine Reagents>, SDS of cas: 112-63-0, the main research area is azidolactone preparation; alkene carboxylic acid cyclic hypervalent iodine azidation cyclization; 1,2 shift; azides; hypervalent iodine; lactones; photoredox.

A versatile synthesis of azidolactones, e.g., I through azidation and cyclization of carboxylic acids onto alkenes, e.g., 2-(1-phenylvinyl)benzoic acid has been developed. Based on either photoredox or palladium catalysis, (1,1) and (1,2) azido lactones can be selectively synthesized. The choice of catalyst and benziodoxol(on)e reagent serving as azide source was essential to initiate either a radical or Lewis acid mediated process with divergent outcome. These transformations were carried out under mild conditions using low catalyst loading and gave access to a large scope of azido lactones.

Zhao, Mingming; Yang, Bin; Li, Liusheng; Si, Yuan; Chang, Meiying; Ma, Sijia; Li, Ronghai; Wang, Yuejun; Zhang, Yu published the artcile< Efficacy of Modified Huangqi Chifeng decoction in alleviating renal fibrosis in rats with IgA nephropathy by inhibiting the TGF-β1/Smad3 signaling pathway through exosome regulation>, COA of Formula: C19H34O2, the main research area is IgA nephropathy exosome Huangqi Chifeng decoction TGFbeta1 Smad3 signaling; Exosomes; IgA nephropathy; Modified Huangqi Chifeng decoction; Renal fibrosis; TGF-β1/Smad3 signaling pathway.

IgA nephropathy is the most common form of primary glomerulonephritis and is a major cause of renal failure worldwide. Modified Huangqi Chifeng decoction (MHCD), a traditional Chinese herbal preparation, has clin. efficacy in reducing the 24-h urine protein levels in patients with IgA nephropathy. However, the mol. mechanism of MHCD needs further study. This study aimed to investigate the mechanisms by which MHCD treatment alleviates renal fibrosis. An IgA nephropathy rat model was established using bovine serum albumin, carbon tetrachloride, and lipopolysaccharide. The rats were divided into control, model, telmisartan, low-dose MHCD, medium-dose MHCD, and high-dose MHCD groups. Treatments were administered to these groups for 8 wk. Subsequently, the 24-h urine protein, serum creatinine, blood urea nitrogen, and blood albumin levels were measured. Pathol. changes and degree of fibrosis in renal tissues were observed, and levels of the transforming growth factor-β1 (TGF-β1)/Smad3 signaling pathway components in renal tissues and TGF-β1 in urinary exosomes were measured. Telmisartan and MHCD reduced 24-h urine protein levels, alleviated renal pathol. injury, and decreased the renal expression of fibronectin, laminin, and collagen IV in rats with IgA nephropathy. Urinary exosomes were extracted and identified for further investigation of their role in renal fibrosis. MHCD reduced TGF-β1 expression in urinary exosomes and reduced TGF-β1 and p-Smad3 levels in renal tissues. MHCD alleviated renal fibrosis in rats with IgA nephropathy by inhibiting the TGF-β1/Smad3 signaling pathway through the downregulation of TGF-β1 expression in exosomes.

Cao, Xu-Liang; Hewitt, C. Nicholas published the artcile< Gas chromatographic determination of volatile alkenes with on-column bromination and electron-capture detection>, Computed Properties of 112-63-0, the main research area is gas chromatog volatile alkene oncolumn bromination.

A method is described for the gas chromatog.-electron-capture detection determination of alkenes via on-column bromination reactions. Pyridinium bromide perbromide (PBPB) was used as the Br2 source, and a cholesterol-glass beads mixture, treated with MeOH, was used to remove excess Br2. The optimum ratio of cholesterol to glass beads is 1:10, at which 93% of the Br released from PBPB can be removed, without removal of the derivatized analytes. The conversion efficiency of alkene to the brominated derivative is extremely low (<2%) for ethene, whereas for propene and 1-butene it is 41 and 79%, resp. For C3-C5 alkenes, this method is 200-300 times more sensitive than anal. of the underivatized analytes by using conventional flame ionization detection.

In the treatment of echinoderm microtubule-associated protein-like 4 (EML4)-anaplastic lymphoma kinase pos. (ALK+) non-small-cell lung cancer (NSCLC), secondary mutations within the ALK kinase domain have emerged as a major resistance mechanism to both first- and second-generation ALK inhibitors. This report describes the design and synthesis of a series of 2,4-diarylaminopyrimidine-based potent and selective ALK inhibitors culminating in identification of the investigational clin. candidate brigatinib. A unique structural feature of brigatinib is a phosphine oxide, an overlooked but novel hydrogen-bond acceptor that drives potency and selectivity in addition to favorable ADME properties. Brigatinib displayed low nanomolar IC50s against native ALK and all tested clin. relevant ALK mutants in both enzyme-based biochem. and cell-based viability assays and demonstrated efficacy in multiple ALK+ xenografts in mice, including Karpas-299 (anaplastic large-cell lymphomas [ALCL]) and H3122 (NSCLC). Brigatinib represents the most clin. advanced phosphine oxide-containing drug candidate to date and is currently being evaluated in a global phase 2 registration trial.

Holc, Conrad; Dimogiannis, Konstantinos; Hopkinson, Emily; Johnson, Lee R. published the artcile< Critical Role of the Interphase at Magnesium Electrodes in Chloride-Free, Simple Salt Electrolytes>, COA of Formula: C19H34O2, the main research area is critical role interphase magnesium electrode salt electrolyte; Mg(TFSI)2; chloride-free electrolyte; magnesium battery; magnesium interphase; tetraglyme.

Mg batteries are a potential beyond Li-ion technol. but currently suffer from poor cycling performance, partly due to the interphase formed when Mg electrodes react with electrolytes. The use of Mg bis(trifluoromethanesulfonyl)imide (Mg(TFSI)2) electrolytes would enable high-voltage intercalation cathodes, but many reports identify poor Mg plating/stripping in the electrolyte solution due to a passivating interphase. Here, the authors have assessed the Mg plating/stripping mechanism at bulk Mg electrodes in a Mg(TFSI)2-based electrolyte by cyclic voltammetry, ex situ FTIR spectroscopy, and electron microscopy and compared this to the cycling of a Grignard-based electrolyte. The authors’ studies indicate a nontypical cycling mechanism at Mg surfaces in Mg(TFSI)2-based electrolytes that occurs through Mg deposits rather than the bulk electrode. FTIR spectroscopy demonstrates an evolution in the interphase chem. during conditioning (repeated cycling) and that this is a critical step for stable cycling in the Mg(TFSI)2-tetraglyme (4G) electrolyte. The fully conditioned electrode in Mg(TFSI)2-4G is able to cycle with an overpotential of <0.25 V without addnl. additives such as Cl- or BH4-.

Park, Hye-Rin; Choi, Hee-Jung; Kim, Bo-Sung; Chung, Tae-Wook; Kim, Keuk-Jun; Joo, Jong-Kil; Ryu, Dongryeol; Bae, Sung-Jin; Ha, Ki-Tae published the artcile< Paeoniflorin enhances endometrial receptivity through leukemia inhibitory factor>, Synthetic Route of 112-63-0, the main research area is endometrial receptivity leukemia inhibitory factor paeoniflorin; embryo implantation; endometrial receptivity; leukemia inhibitory factor; paeoniflorin.

Despite advances in assisted reproductive technol., treatment for deficient endometrial receptivity is a major clin. unmet need. In our previous study, the water extract of Paeonia lactiflora Pall. enhanced endometrial receptivity in vitro and in vivo via induction of leukemia inhibitory factor (LIF), an interleukin (IL)-6 family cytokine. In the present study, we found that paeoniflorin, a monoterpene glycoside, is the major active compound of P. lactiflora. Paeoniflorin significantly improved the embryo implantation rate in a murine model of mifepristone (RU486)-induced implantation failure. In addition, paeoniflorin increased the adhesion of human trophectoderm-derived JAr cells to endometrial Ishikawa cells through the expression of LIF in vitro. Moreover, using the National Center for Biotechnol. Information (NCBI) Gene Expression Omnibus (GEO) database of the human endometrium, we confirmed that LIF signaling is a key regulator for improving human endometrial receptivity. Therefore, these results suggest that paeoniflorin might be a potent drug candidate for the treatment of endometrial implantation failure by enhancing endometrial receptivity..

Fluoride ion induced polarity enhancement of arylboronate esters>, HPLC of Formula: 112-63-0, the main research area is boronate dioxaborolane stilbene nitro derivative preparation complexation fluoride anion; formation constant equilibrium fluoride addition boronate nitrostilbene derivative; UV vis spectra solvatochromism nitrostilbene boronate derivative fluoride adduct; solvent effect Kamlet Taft equation boronate nitrostilbene fluoride adduct; optimized mol structure dioxaborolane stilbene nitro derivative fluoride adduct; excitation energy vertical dioxaborolane stilbene nitro derivative fluoride adduct; bond length conjugate dioxaborolane stilbene nitro derivative fluoride adduct; hydrogen bonding solvent dioxaborolane stilbene nitro derivative fluoride adduct; electron density NBO dioxaborolane stilbene nitro derivative fluoride adduct; crystal structure dioxaborolane stilbene nitro derivative; mol structure dioxaborolane stilbene nitro derivative.

A series of stilbeneboronate pinacol cyclic esters, containing none to three nitro groups, (E)-(CMe2O)2B-1,4-C6H4CH:CHC6Hn(NO2)5-n-2,4,6 (3-6; n = 0-3) were prepared by Horner-Emmons-Wadsworth olefination of 4-(4,4,5,5-tetramethyl-1,3,2-dioxaborolan-2-yl)benzaldehyde (2) or by condensation of 2 with 2,4-dinitrophenylacetic acid or 2,4,6-trinitrotoluene. Compounds 3-6 were characterized by x-ray single-crystal structure anal. Compounds 3-6 undergo reversible and solvent-dependent addition of fluoride ion by reaction with Bu4NF, forming adducts 3路F–6路F-; the equilibrium systems feature isosbestic points in UV-vis. spectra. A stilbeneboronate ester bearing electron-acceptor groups experiences transition to a push-pull 蟺-electron system upon complexation with one fluoride ion at the boron atom. The UV-vis absorption maxima of the presented nitro-substituted stilbeneboronate esters are red-shifted upon addition of fluoride ions, indicating this binding event. The enhancement of the polarity of the investigated compounds and the changes in the electronic system were investigated by UV-vis absorption spectroscopy and solvatochromism. Addnl., studies were performed by natural bond orbital (NBO) anal. and RI-CC2 calculations of the vertical excitation energies. The synergism of fluoride ion complexation and solvation upon the UV-vis band shift is interpreted in terms of linear solvation energy relationships (LSERs) using the Kamlet-Taft solvent parameter set. It is found that the UV-vis absorption of the fluoro-boronates is strongly dependent on the solvents hydrogen-bond donating ability.
