The current study was conducted to examine the in vitro anticancer potential of Cordia dichotoma (bark, leaves, pulp and seed). The plant material was collected from UT of J&K and methodical bioassays were carried out on ten human cancer cell lines Michigan Cancer Foundation-7 (MCF-7), M.D. Anderson-Metastatic Breast (MDA-MB-231), Neuroblastoma-2a (N2A), SH-SY5Y, U-251, HCT-116, SW-620, A-549, MIA PaCa-2, Panc-1 from five different origins (breast, CNS, colon, lung, pancreas) resp. Methanolic extracts were produced and fractions were then obtained from the extracts and evaluated for cytotoxicity. Mechanistic assays, HPLC, and GCMS profiling were performed on the highest active fraction. The Sulforhodamine B (SRB) assay determined the in vitro cytotoxicity. The findings revealed that the bark portion had in vitro cytotoxicity against the A-549 human lung cancer cell line. To our knowledge, this is the first study to show that the plant’s bark has anticancer properties and induced chromatin condensation, confirmed cell death via ROS generation, and significantly decreased colony formation in A-549 cell line from lung origin in a dose-dependent manner. Furthermore, HPLC and GCMS investigations indicated the presence of a number of bioactive mols. such as gallic acid (144,969.86) uV*sec, caffeic acid (104.26) uV*sec, ferulic acid (472.87) uV*sec, vanillic acid (13,775.39) uV*sec, palmitic acid (18.34%), cis vaccenic acid (28.81%), etc. and one of the compounds was reported for the first time from the bark. As a result of its promising efficacy, it may become an essential cancer chemopreventive or chemotherapeutic medication for patients with lung carcinoma.

Hassler, Carla; Zhang, Yanan; Gilmour, Brian; Graf, Tyler; Fennell, Timothy; Snyder, Rodney; Deschamps, Jeffrey R.; Reinscheid, Rainer K.; Garau, Celia; Runyon, Scott P. published the artcile< Identification of Neuropeptide S Antagonists: Structure-Activity Relationship Studies, X-ray Crystallography, and in Vivo Evaluation>, Formula: C19H34O2, the main research area is diphenyltetrahydro oxazolo pyrazinone derivative preparation structure neuropeptide S antagonist.

Modulation of the neuropeptide S (NPS) system has been linked to a variety of CNS disorders such as panic disorder, anxiety, sleeping disorders, asthma, obesity, PTSD, and substance abuse. In this study, a series of diphenyltetrahydro-1H-oxazolo[3,4-α]pyrazin-3(5H)-ones were synthesized and evaluated for antagonist activity at the neuropeptide S receptor. The absolute configuration was determined by chiral resolution of the key synthetic intermediate, followed by anal. of one of the individual enantiomers by X-ray crystallog. The R isomer was then converted to a biol. active compound (34) that had a Ke of 36 nM. The most potent compound displayed enhanced aqueous solubility compared with the prototypical antagonist SHA-68 and demonstrated favorable pharmacokinetic properties for behavioral assessment. In vivo anal. in mice indicated a significant blockade of NPS induced locomotor activity at an i.p. dose of 50 mg/kg. This suggests that analogs having improved drug-like properties will facilitate more detailed studies of the neuropeptide S receptor system.

Sorrenti, Valeria; Vanella, Luca; Platania, Chiara Bianca Maria; Greish, Khaled; Bucolo, Claudio; Pittala, Valeria; Salerno, Loredana published the artcile< Novel heme oxygenase-1 (HO-1) inducers based on dimethyl fumarate structure>, Application of C19H34O2, the main research area is unsaturated dicarbonyl compound preparation heme oxygenase docking; HO-1 inducers; LX-2 cells; dimethyl fumarate (DMF); heme oxygenase (HO); hepatic fibrosis.

Novel heme oxygenase-1 (HO-1) inducers based on di-Me fumarate (DMF) structure I [R = H, 4-Me, 2-CO2H, etc.; R1 = Me, Ph, 4-ClC6H4, etc.; X = O, NH; Y = a bond, CH2, CH2CH2, CH2CH2CH2] were reported in this paper. These compounds were obtained by modification of the DMF backbone. Particularly, maintaining the α, β-unsaturated dicarbonyl function as the central chain crucial for HO-1 induction, different substituted or unsubstituted Ph rings are introduced by means of an ester or amide linkage. Sym. and asym. derivatives were synthesized. All compounds were tested on a human hepatic stellate cell line LX-2 to assay their capacity for modifying HO-1 expression. Compounds I [R = H, R1 = Ph, X = O, Y = null; R = 4-Cl, R1 = 4-ClC6H4, X = O, Y = null; R = H, R1 = Ph, X = NH, Y = CH2] stand out for their potency as HO-1 inducers, being 2-3 fold more active than DMF, and for their ability to reverse reactive oxygen species (ROS) production mediated using palmitic acid (PA). These properties, coupled with a low toxicity toward LX-2 cell lines, made these compounds potentially useful for treatment of diseases in which HO-1 overexpression may counteract inflammation, such as hepatic fibrosis. Docking studies showed a correlation between predicted binding free energy and exptl. HO-1 expression data. These preliminary results might support the development of new approaches in the management of liver fibrosis.

Hegde, Guruprasad S.; Sundara, Ramaprabhu published the artcile< Entropy Stabilized Oxide Nanocrystals as Reaction Promoters in Lithium-O2 Batteries>, Category: esters-buliding-blocks, the main research area is lithium peroxide nanocrystal secondary battery electrochem performance.

Charge transport limitations at the Li2O2 discharge product-electrode interfaces hinder the rechargeability of Li-O2 batteries. Herein, we introduce entropy stabilized oxides (ESO) as reaction promoters in pos. electrodes that can facilitate charge transport by reducing the binding energy of the intermediates. In this work, we developed a rock-salt type entropy stabilized oxide. We show that the rock salt phase transforms into a pure, equimolar, quinary spinel on heat treatment. A Li-O2 battery with the developed ESOs at the pos. electrode is cycled with an areal capacity of 1 mAh cm-2 at a current rate of 0.25 mA cm-2 to study its role as a reaction promoter. The surface, bulk, and morphol. characterization are carried out for both materials. The presence of multiple cations and defects on the surface of the ESO is found to benefit the discharge product oxidation and improve the cyclic stability.

Liu, Chengwei; Ji, Chong-Lei; Hong, Xin; Szostak, Michal published the artcile< Palladium-Catalyzed Decarbonylative Borylation of Carboxylic Acids: Tuning Reaction Selectivity by Computation>, Application of C19H34O2, the main research area is palladium catalyst decarbonylative borylation carboxylic acid mol modeling; carboxylic acids; computational chemistry; decarbonylation; regioselectivity; transition-metal catalysis.

Decarbonylative borylation of carboxylic acids is reported. Carbon electrophiles are generated directly after reagent-enabled decarbonylation of the in situ accessible sterically-hindered acyl derivative of a carboxylic acid under catalyst controlled conditions. The scope and the potential impact of this method are demonstrated in the selective borylation of a variety of aromatics (>50 examples). This strategy was used in the late-stage derivatization of pharmaceuticals and natural products. Computations reveal the mechanistic details of the unprecedented C-O bond activation of carboxylic acids. By circumventing the challenging decarboxylation, this strategy provides a general synthetic platform to access arylpalladium species for a wide array of bond formations from abundant carboxylic acids. The study shows a powerful combination of experiment and computation to predict decarbonylation selectivity.

Yu, Jin-Sheng; Zhou, Feng; Liu, Yun-Lin; Zhou, Jian published the artcile< Organocatalytic asymmetric Michael addition of unprotected 3-substituted oxindoles to 1,4-naphthoquinone>, HPLC of Formula: 112-63-0, the main research area is indole quaternary stereogenic center preparation enantioselective synthesis; organocatalyst asym Michael addition oxindole naphthoquinone; 3,3-disubstituted oxindoles; Michael addition; organocatalysis; quaternary stereogenic center; unprotected 3-substituted oxindoles.

The authors reported the first example of an organocatalytic Michael addition of unprotected 3-prochiral oxindole derivatives to 1,4-naphthoquinone. A quinidine derivative (DHQD)2PYR was found to catalyze this reaction in up to 83% ee, with moderate to excellent yields. This method could be used for the synthesis of enantioenriched 3,3-diaryloxindole derivatives, the catalytic synthesis of which was unprecedented. The synthesis of the target compound was achieved using 1,3-dihydro-2H-indol-2-one derivatives and 1,4-naphthalenedione as starting materials. The title compounds thus formed included a 2-(2-oxo-3-indolyl)-1,4-naphthalenedione derivative (I) and related substances.

However, few studies have explored dependent peptide search results in an untargeted way. In the present study, we sought to evaluate dependent peptide searching as a means of characterizing proteins that have been modified in vitro. We generated a model data set by analyzing N-ethylmaleimide-treated bovine serum albumin, and performed dependent peptide searches using the popular MaxQuant software. To facilitate interpretation of the search results (hundreds of dependent peptides), we developed a series of visualisation tools (R scripts). We used the tools to assess the diversity of putative modifications in the albumin, and to pinpoint hypothesised modifications. We went on to explore the tools’ generality via analyses of public data from studies of rat and human proteomes. Of 19 expected sites of modification (one in rat cofilin-1 and 18 across six different human plasma proteins), eight were found and correctly localised. Apparently, some sites went undetected because chem. enrichment had depleted necessary analytes (potential ‘base’ peptides). Our results demonstrate (i) the ability of the tools to provide accurate and informative visualisations, and (ii) the usefulness of dependent peptide searching for characterizing in vitro protein modifications. Our model data are available via PRIDE/ProteomeXchange (accession number PXD013040).
