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.

Beni, Ryan; Boadi, William; Karim, Kaleh; Alnakhli, Jawzah; Alhamed, Samiyah published the artcile< Synthesis and antiproliferative activities of triphenylmethanol conjugates of leuprorelin>, Formula: C19H16O, the main research area is leuprorelin triphenylmethanol conjugate antiproliferative invasive ductal prostate carcinoma adipocyte.

Leuprorelin (LEP) is an FDA drug for breast cancer and prostate cancer treatment. There are several reported adverse effects such as transient hypertension, excessive salivation, and increased dysuria during treatment with LEP. In this study, the efficacy and toxicity of LEP were modified by using a drug delivery system to adjust the physicochem. properties. In this regard, Leuprorelin conjugates of triphenylmethanol derivatives (TPMs) were synthesized as prodrugs. Comparative antiproliferative assays showed that LEP-TPMs conjugates had significantly higher antiproliferative activities than the corresponding non-covalent phys. mixtures of the TPMs and LEP against human invasive ductal carcinoma (BT549), human prostate carcinoma (PC3), human lung cancer (A549) and mouse pre-adipocytes (3T3-L1) cells.

Moeini, Nazanin; Molaei, Somayeh; Ghadermazi, Mohammad published the artcile< Selective oxidation of sulfides and synthesis of 5-substituted 1H-tetrazoles on Ce (III) immobilized CoFe2O4 as a magnetically separable, highly active, and reusable nanocatalyst>, Safety of 2-(Phenylthio)ethanol, the main research area is cobalt iron oxide nanocatalyst cerium immobilized amino glycol preparation; tetrazole green preparation; nitrile sodium azide cobalt iron oxide nanocatalyst cerium immobilized; sulfoxide green preparation; sulfide oxidation cobalt iron oxide nanocatalyst cerium immobilized.

Reactions of CoFe2O4 magnetic nanoparticles supported ligands, 2-amino-2-methyl-1,3-propanediol (Amino glycol), with cerium salts provided the resp. anchored complex CoFe2O4 @Amino glycol/Ce. The nanocatalyst was characterized perfectly using thermogravimetric analyzes, FT-IR spectroscopy, SEM, energy-dispersive X-ray inductively coupled plasma optical emission spectroscopy vibrational sample magnetometry and powder X-ray diffraction. CoFe2O4 magnetic nanoparticles supported ligands with cerium salts afforded active catalysts for the synthesis of 5-substituted 1H-tetrazoles I [R = Ph, 2-ClC6H4, Bn, etc.] via reaction of nitriles and sodium azide/oxidation of sulfides RSR1 [R = Ph, n-Pr, Et, etc.; R1 = Me, Bn, Ph, etc.] using Me Ph sulfide with H2O2 as oxidant at mild reaction conditions in the green medium under optimized conditions. The ligand and metal atom identity influenced the catalytic activity of the nanocatalyst. The immobilized complexes were easily collected via an external magnetic field and further reused at least 6 times without significant loss of catalytic activity and selectivity.

Owing to their participation in Click reactions, bifunctional azides are valuable intermediates in the preparation of medicines and biochem. tool compounds Despite the privileged nature of pyridines among pharmaceutical scaffolds, reports of the synthesis and characterization of azidopyridines bearing a halogen substituent for further elaboration are almost completely unknown in the literature. As azidopyridines carry nearly equal numbers of nitrogen and carbon atoms, we hypothesized that safety concerns limited the application of these useful bifunctional building blocks in medicinal and biol. chem. To address this concern, we prepared and characterized nine azidopyridines bearing a single fluorine, chlorine, or bromine atom. All were examined by differential scanning calorimetry (DSC), in which they demonstrated exotherms of 228-326 kJ/mol and onset temperatures between 119 and 135°C. Selected azidopyridines were advanced to mech. stress testing, in which impact sensitivity was noted for one regioisomer of C5H3FN4. The utility of these versatile intermediates was demonstrated through their use in a variety of Click reactions and the diversification of the halogen handles.

Cook, Ian; Leyh, Thomas S. published the artcile< The N-Terminus of Human Sulfotransferase 2B1b-a Sterol-Sensing Allosteric Site>, Recommanded Product: (3S,9S,10R,13R,14R,17R)-10,13-Dimethyl-17-((R)-6-methylheptan-2-yl)-2,3,4,9,10,11,12,13,14,15,16,17-dodecahydro-1H-cyclopenta[a]phenanthren-3-ol, the main research area is sulfotransferase SULT2B1b allosteric site allostere quercetin oxysterol.

Among human cytosolic sulfotransferases, SULT2B1b is highly specific for oxysterols-oxidized cholesterol derivatives, including nuclear-receptor ligands causally linked to skin and neurodegerative diseases, cancer and atherosclerosis. Sulfonation of signaling oxysterols redirects their receptor-binding functions, and controlling these functions is expected to prove valuable in disease prevention and treatment. SULT2B1b is distinct among the human SULT2 isoforms by virtue of its atypically long N-terminus, which extends 15 residues beyond the next longest N-terminus in the family. Here, in silico studies are used to predict that the N-terminal extension forms an allosteric pocket and to identify potential allosteres. One such allostere, quercetin, is used to confirm the existence of the pocket and to demonstrate that allostere binding inhibits turnover. The structure of the pocket is obtained by positioning quercetin on the enzyme, using spin-label-triangulation NMR, followed by NMR distance-constrained mol. dynamics docking. The model is confirmed using a combination of site-directed mutagenesis and initial-rate studies. Stopped-flow ligand-binding studies demonstrate that inhibition is achieved by stabilizing the closed form of the enzyme active-site cap, which encapsulates the nucleotide, slowing its release. Finally, endogenous oxysterols are shown to bind to the site in a highly selective fashion-one of the two immediate biosynthetic precursors of cholesterol (7-dehydrocholesterol) is an inhibitor, while the other (24-dehydrocholesterol) is not. These findings provide insights into the allosteric dialogue in which SULT2B1b participates in in vivo and establishes a template against which to develop isoform-specific inhibitors to control SULT2B1b biol.

Gluconic acid and its derivatives are extensively used in pharmaceutical, food, textile, and pulp and paper branches of industry during production of food additives, cleansers, medicinal drugs, stabilizers, etc. To obtain gluconic acid, the method of conversion of glucose into gluconic acid by mol. oxygen in the presence of solid catalysts is promising. The process of obtaining Pd and bimetallic nanoparticles Pd-Bi, coated on Al2O3, has been considered in the work. Samples were prepared by combined and successive impregnation of the Al2O3 support using metalloorg. precursors Pd(acac)2, Bi(ac)3, and dissolved in an organic solvent (acetic acid), followed by the removal of excess solvent. To achieve the formation of Pd and bimetallic nanoparticles Pd-Bi on the substrate surface, the synthesized samples were subjected to thermal decomposition sequentially in the atm. of Ar, O2, and H2. The surface of the obtained catalysts was studied by a combination of physicochem. methods of anal. The catalysts were analyzed in the reaction of liquid phase oxidation of glucose. The best results are achieved in the presence of the catalyst obtained by combined impregnation.

Jelicic, Mario-Livio; Brusac, Edvin; Klaric, Daniela Amidzic; Nigovic, Biljana; Turk, Niksa; Mornar, Ana published the artcile< A chromatographic approach to development of 5-aminosalicylate/folic acid fixed-dose combinations for treatment of Crohn's disease and ulcerative colitis>, Quality Control of 6054-98-4, the main research area is chromatog aminosalicylate folic acid treatment Crohn disease ulcerative colitis.

Medication adherence is an important factor in inflammatory bowel disease therapy, which includes regular supplementation of malabsorbed vitamins. Absorption of folic acid is limited due to the damaging of the gastrointestinal tract, which can increase the chances to develop megaloblastic anemia and colorectal cancer. In this work, 5-aminosalicylates (mesalazine, balsalazide, sulfasalazine and olsalazine) and folic acid were characterized regarding their pharmacokinetic related properties (hydrophobicity, phospholipid and plasma protein binding) using the biomimetic chromatog. approach. Despite the high binding percentage of 5-aminosalicylates for human serum albumin (> 61.44%), results have shown that folic acid binding to human serum albumin protein is far greater (69.40%) compared to alpha 1-acid-glycoprotein (3.45%). Frontal anal. and zonal elution studies were conducted to provide an insight into the binding of folic acid to human serum albumin and potential competition with 5-aminosalicylates. The anal. method for the simultaneous determination of assay in proposed fixed-dose combinations was developed and validated according to ICH Q2 (R1) and FDA method validation guidelines. Separation of all compounds was achieved within 16 min with satisfactory resolution (Rs > 3.67) using the XBridge Ph column (150 x 4.6 mm, 3.5μm). High linearity (r > 0.9997) and precision (RSD < 2.29%) was obtained, while all recoveries were within the regulatory defined range by British (100.0 ± 5.0%) and USP (100.0 ± 10.0%).

Bai, Renren; Zhu, Junlong; Bai, Ziqiang; Mao, Qing; Zhang, Yingqian; Hui, Zi; Luo, Xinyu; Ye, Xiang-Yang; Xie, Tian published the artcile< Second generation β-elemene nitric oxide derivatives with reasonable linkers: potential hybrids against malignant brain glioma>, Computed Properties of 699-12-7, the main research area is beta elemene nitric oxide malignant brain glioma antitumor; NO donor; anti-tumour; malignant glioma; natural product; β-Elemene.

Elemene is a second-line broad-spectrum anti-tumor drug that has been used in China for more than two decades. However, its main anti-tumor ingredient, β-elemene, has disadvantages, including excessive lipophilicity and relatively weak anti-tumor efficacy. To improve the anti-tumor activity of β-elemene, based on its minor mol. weight character, we introduced furoxan nitric oxide (NO) donors into the β-elemene structure and designed six series of new generation β-elemene NO donor hybrids. The synthesized compounds could effectively release NO in vitro, displayed significant anti-proliferative effects on U87MG, NCI-H520, and SW620 cell lines. In the orthotopic glioma model, compound significantly and continuously suppressed the growth of gliomas in nude mice, and the brain glioma of the treatment group was markedly inhibited (>90%). In short, the structural fusion design of NO donor and β-elemene is a feasible strategy to improve the in vivo anti-tumor activity of β-elemene.
