Tironi, Matteo; Dix, Stefan; Hopkinson, Matthew N. published the artcile< Deoxygenative nucleophilic difluoromethylselenylation of carboxylic acids and alcohols with BT-SeCF2H>, Category: alcohols-buliding-blocks, the main research area is carboxylic acid alc difluoromethylselenylation deoxygenative nucleophilic.

The benzothiazolium salt BT-SeCF2H is introduced as an efficient nucleophilic reagent for transferring difluoromethylselenyl groups onto organic mols. SeCF2H-Containing selenoesters could be prepared upon deoxygenative substitution of readily available carboxylic acids, while silver catalysis allowed for efficient formation of (difluoromethyl)selenoethers, including the established electrophilic reagent BnSeCF2H, directly from simple alcs. To the best of knowledge, these deoxygenative reactions represent the first reported nucleophilic difluoromethylselenylation processes and thus open up new approaches to prepare valuable fluorinated compounds

Markert, Christian; Thoma, Gebhard; Srinivas, Honnappa; Bollbuck, Birgit; Luond, Rainer M.; Miltz, Wolfgang; Walchli, Rudolf; Wolf, Romain; Hinrichs, Jurgen; Bergsdorf, Christian; Azzaoui, Kamal; Penno, Carlos A.; Klein, Kai; Wack, Nathalie; Jager, Petra; Hasler, Franziska; Beerli, Christian; Loetscher, Pius; Dawson, Janet; Wieczorek, Grazyna; Numao, Shin; Littlewood-Evans, Amanda; Rohn, Till A. published the artcile< Discovery of LYS006, a Potent and Highly Selective Inhibitor of Leukotriene A4 Hydrolase>, HPLC of Formula: 167938-56-9, the main research area is tetrazole derivative LYS 006 preparation LTA4H inhibitor antiinflammatory activity.

The cytosolic metalloenzyme leukotriene A4 hydrolase (LTA4H) is the final and rate-limiting enzyme in the biosynthesis of pro-inflammatory leukotriene B4 (LTB4). Preclin. studies have validated this enzyme as an attractive drug target in chronic inflammatory diseases. Despite several attempts, no LTA4H inhibitor has reached the market, yet. Herein, we disclose the discovery and preclin. profile of LYS006 (I), a highly potent and selective LTA4H inhibitor. A focused fragment screen identified hits that could be cocrystd. with LTA4H and inspired a fragment merging. Further optimization led to chiral amino acids and ultimately to LYS006, a picomolar LTA4H inhibitor with exquisite whole blood potency and long-lasting pharmacodynamic effects. Due to its high selectivity and its ability to fully suppress LTB4 generation at low exposures in vivo, LYS006 has the potential for a best-in-class LTA4H inhibitor and is currently investigated in phase II clin. trials in inflammatory acne, hidradenitis suppurativa, ulcerative colitis, and NASH.

Fliri, Anton F.; Loging, William T.; Volkmann, Robert A. published the artcile< Drug effects viewed from a signal transduction network perspective>, Product Details of C14H8N2Na2O6, the main research area is drug discovery protein network signaling.

Understanding how drugs affect cellular network structures and how resulting signals are translated into drug effects holds the key to the discovery of medicines. Herein we examine this cause-effect relationship by determining protein network structures associated with the generation of specific in vivo drug-effect patterns. Medicines having similar in vivo pharmacol. have been identified by a comparison of drug-effect profiles of 1320 medicines. Protein network positions reached by these medicines were ascertained by examining the coinvestigation frequency of these medicines and 1179 protein network constituents in millions of scientific investigations. Interestingly, medicine associations obtained by comparing by drug-effect profiles mirror those obtained by comparing drug-protein coinvestigation frequency profiles, demonstrating that these drug-protein reachability profiles are relevant to in vivo pharmacol. By using protein associations obtained in these investigations and independent, curated protein interaction information, drug-mediated protein network topol. models can be constructed. These protein network topol. models reveal that drugs having similar pharmacol. profiles reach similar discrete positions in cellular protein network systems and provide a network view of medicine cause-effect relationships.

Witman, Matthew; Ling, Sanliang; Anderson, Samantha; Tong, Lianheng; Stylianou, Kyriakos C.; Slater, Ben; Smit, Berend; Haranczyk, Maciej published the artcile< In silico design and screening of hypothetical MOF-74 analogs and their experimental synthesis>, Name: Sodium 5,5′-(diazene-1,2-diyl)bis(2-hydroxybenzoate), the main research area is MOF 74 olsalazine sodium in silico Monte Carlo simulation.

In this work we present the in silico design of metal-organic frameworks (MOFs) exhibiting 1-dimensional rod topologies. We introduce an algorithm for construction of this family of MOF topologies, and illustrate its application for enumerating MOF-74-type analogs. Furthermore, we perform a broad search for new linkers that satisfy the topol. requirements of MOF-74 and consider the largest database of known chem. space for organic compounds, the PubChem database. Our in silico crystal assembly, when combined with dispersion-corrected d. functional theory (DFT) calculations, is demonstrated to generate a hypothetical library of open-metal site containing MOF-74 analogs in the 1-D rod topol. from which we can simulate the adsorption behavior of CO2. We finally conclude that these hypothetical structures have synthesizable potential through computational identification and exptl. validation of a novel MOF-74 analog, Mg2(olsalazine).

Rozdzynska-Swiatkowska, A.; Ciara, E.; Halat-Wolska, P.; Krajewska-Walasek, M.; Jezela-Stanek, A. published the artcile< Anthropometric characteristics of 65 Polish Smith-Lemli-Opitz patients>, HPLC of Formula: 434-16-2, the main research area is smith lemli opitz syndrome; 7-Dehydrocholesterol; Anthropometry; DHCR7 gene; Growth; Smith-Lemli-Opitz syndrome.

Abstract: Smith-Lemli-Opitz syndrome (SLOS) belongs to a group of multiple congenital anomaly/developmental delay disorders. Its primary cause lies in the defect in cholesterol biosynthesis-7-dehydrocholesterol reductase (DHCR7)-caused by pathogenic variants in the homonymous gene. Anthropometric anomalies, especially growth restriction and microcephaly, are among the most common phys. manifestations of SLOS. There have been no studies analyzing the correlation between genotype, biochem. marker (7-dehydrocholesterol), and the birth and growth parameters for individuals with SLOS. This paper presents anthropometric data from the group of 65 Polish patients (aged 0.1 to 18 years) with Smith-Lemli-Opitz syndrome, with genotype and biochem. correlations for birth parameters, as well as growth in relation to mol. DHCR7 variants.

Fogacci, Federica; Tocci, Giuliano; Presta, Vivianne; Fratter, Andrea; Borghi, Claudio; Cicero, Arrigo F. G. published the artcile< Effect of resveratrol on blood pressure: A systematic review and meta-analysis of randomized, controlled, clinical trials>, Reference of 501-36-0 , the main research area is Resveratrol; blood pressure; meta-analysis; metaregression; type 2 diabetes.

Results of previous clin. trials evaluating the effect of resveratrol supplementation on blood pressure (BP) are controversial. We aimed to assess the impact of resveratrol on BP through systematic review of literature and meta-anal. of available randomized, controlled clin. trials (RCTs). Literature search included SCOPUS, PubMed-Medline, ISI Web of Science and Google Scholar databases up to 17th Oct. 2017 to identify RCTs investigating the impact of resveratrol on BP. Two review authors independently extracted data on study characteristics, methods and outcomes. Overall, the impact of resveratrol on BP was reported in 17 trials. Administration of resveratrol did not significantly affect neither systolic BP [weighted mean difference (WMD): -2.5 95% CI:(-5.5, 0.6) mmHg; p=0.116; I2=62.1%], nor diastolic BP [WMD: -0.5 95% CI:(-2.2, 1.3) mmHg; p=0.613; I2=50.8], nor mean BP [MAP; WMD: -1.3 95% CI:(-2.8, 0.1) mmHg; p=0.070; I2=39.5%] nor pulse pressure [PP; WMD: -0.9 95% CI:(-3.1, 1.4) mmHg; p=0.449; I2=19.2%]. However, significant WMDs were detected in subsets of studies categorized according to high resveratrol daily dosage (≥300 mg/day) and presence of diabetes. Meta-regression anal. revealed a pos. association between systolic BP-lowering resveratrol activity (slope: 1.99; 95% CI: 0.05, 3.93; two-tailed p= 0.04) and Body Mass Index (BMI) at baseline, while no association was detected neither between baseline BMI and MAP-lowering resveratrol activity (slope: 1.35; 95% CI: -0.22, 2.91; two-tailed p= 0.09) nor between baseline BMI and PP-lowering resveratrol activity (slope: 1.03; 95% CI: -1.33, 3.39; two-tailed p= 0.39). Resveratrol was fairly well-tolerated and no serious adverse events occurred among most of the eligible trials. The favorable effect of resveratrol emerging from the current meta-anal. suggests the possible use of this nutraceutical as active compound in order to promote cardiovascular health, mostly when used in high daily dose (≥300 mg/day) and in diabetic patients.
