Effect of Growth Hormone (GH) and Resistance Training on the Collagen Properties of Femoral Bone Tissue

The indiscriminate use of anabolic steroids in gyms has been growing in a generalized way, among which, the most common is growth hormone (GH). In the short term GH may potentiate muscle growth, especially when taken in combination with resistance training. However, the effects of this hormone are not yet fully understood in the literature, especially in relation to collagen properties. The objective of this study was to evaluate the effect of the application of growth hormone (GH) and resistance training (RT) on the collagen properties of femoral bone tissue using Raman Spectroscopy. In this study 40 male rats were randomly distributed into four groups (n=10): control (C), control and GH application (GH), resistance training (T), and resistance training and GH application (GHT). The training consisted of four series of 10 water jumps, performed three times a week, with an overload corresponding to 50 % of body weight and duration of four weeks. GH was applied at a dosage of 0.2 IU/Kg (0.067 mg/kg) to each animal, three times a week, every other day. The animals were euthanized and the right femurs were collected for analysis of bone structure. Raman spectroscopy (RS) was used to observe the following compounds from their respective bands: type I collagen (662 cm(-1)), amide III (1243 cm(-1)), proteins including type I collagen (1278 cm(-1)), woven collagen (1322 cm(-1)), association of collagen, phospholipids, nucleic acid, and phosphate (1330 cm(-1)), and collagen and protein deformation (1448 cm(-1)). The results demonstrated an increase in the collagen properties in all analyzed variables, however, the T group presented a statistically significant difference (p<0.05). It is possible to conclude that isolated physical training was shown to be more efficient than when combined with the application of GH to increase the collagen properties of the femoral bone tissue. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.

Chemical Protectors against the Toxic Effects of Paracetamol (Acetaminophen) and Its Meta Analogue: Preventing Protein Arylation

The potential role of nine thiols as chemical protectors against the toxicity of paracetamol (acetaminophen, APAP) and its meta analogue N-acetyl-m-aminophenol (AMAP) was investigated using the density functional theory. They are glutathione (GSH), N-acetylcysteine (NAC), NAC amide (NACA), tiopronine (TPR), dihydrolipoic acid (DHL), 6-mercaptopurine (6MP), 6-thioguanine (6TG), 2,3-dimercaprol (DMC), and D-penicillamine (PNA). The investigation was focused on the toxic effects derived from protein arylation at cysteine residues, induced by the quinone imines formed from APAP and AMAP. On the basis of both thermochemical and kinetic considerations, with the exceptions of 6MP and 6TG, the investigated thiols may be useful in protecting the chemical integrity of cysteine residues in proteins from arylation by quinone imines. The order of efficiency for that purpose is predicted to be NAC > GSH > TPR > NACA > DMC > DHL. However, considering physicochemical properties that may affect bioavailability and cell permeability, DHL seems to be the best prospect to be orally supplied.

Visible-light-promoted selective C-H amination of heteroarenes with heteroaromatic amines under metal-free conditions

The regioselective C-H amination of quinoline amides (C5) and imidazopyridines (C3) under transition-metal-free conditions at room temperature with a high degree of functional group tolerance is reported. The C-H amination promoted by visible light in the presence of a photocatalyst with a wide range of heteroamines makes the present protocol more sustainable.

Organic carbon characteristics in density fractions of soils with contrasting mineralogies

This study was aimed to evaluate the role of minerals in the preservation of organic carbon (OC) in different soil types. Sequential density fractionation was done to isolate particulate organic matter (POM, < 1.8 g cm(-3)) and mineral associated OM (MOM: 1.8-2.2, 2.2-2.6 and > 2.6 g cm(-3)) from four soils, i.e., a Ferralsol, a Luvisol, a Vertisol and a Solonetz. Organic matter (OM) in the density fractions was characterised using diffuse reflectance Fourier transform infrared spectroscopy, X-ray photoelectron spectroscopy and mass spectroscopy in the original states (i.e., without any chemical pre-treatment), and after 6% sodium hypochlorite (NaOCl) and 10% hydrofluoric acid (HF) treatments. The NaOCl oxidation resistant fraction was considered as a relatively stable pool of OC and the HF soluble fraction was presumed as the mineral bound OC. Phyllosilicate-dominated soils, i.e., Vertisol, Luvisol and Solonetz, contained a greater proportion of POM than Fe and Al oxide-dominated Ferralsol. Wider C:N ratio and lower delta C-13 and delta N-15 in POM suggest the dominance of labile OC in this fraction and this was also supported by a greater proportion of NaOCl oxidised OC in the same fraction that was enriched with aliphatic C. The sequential density fractionation method effectively isolated OM into three distinct groups in the soils: (i) OM associated with Fe and Al oxides (> 1.8 g cm(-3) in the Ferralsol); (ii) OM associated with phyllosilicates (1.8-2.6 g cm(-3)) and (iii) OM associated with quartz and feldspar (> 2.6 g cm(-3)) in the other three soils. Greater oxidation resistance, and more dissolution of OC during the HF treatment in the Fe and Al oxides dominated fractions suggest a greater potential of these minerals to protect OC from oxidative degradation as compared to the phyllosilicates, and quartz and feldspar matrices. OM associated with Fe and Al oxides was predominantly aromatic and carboxylate C. Decreased C: N ratio in the NaOCl oxidation resistant OM and HF soluble OM of phyllosilicates, and quartz and feldspars dominant fractions compared to their untreated fractions indicate a preferred retention of N rich organic compounds by these minerals. OM associated with phyllosilicates was enriched with protonated amide N and aromatic C. Quartz and feldspars associated OM comprised of N containing organic compounds and polysaccharides, although we don’t expect any role of these minerals in their preservation. Our results imply that the abundance and surface properties of minerals in the soil largely control the dynamics of OC and subsequently protect OC from microbial cycling. (C) 2017 Elsevier Ltd.

An efficient synthetic route to l-gamma-methyleneglutamine and its amide derivatives, and their selective anticancer activity

In cancer cells, glutaminolysis is the primary source of biosynthetic precursors, fueling the TCA cycle with glutamine-derived alpha-ketoglutarate. The enhanced production of alpha-ketoglutarate is critical to cancer cells as it provides carbons for the TCA cycle to produce glutathione, fatty acids, and nucleotides, and contributes nitrogens to produce hexosamines, nucleotides, and many nonessential amino acids. Efforts to inhibit glutamine metabolism in cancer using amino acid analogs have been extensive. l-gamma-Methyleneglutamine was shown to be of considerable biochemical importance, playing a major role in nitrogen transport in Arachis and Amorpha plants. Herein we report for the first time an efficient synthetic route to l-gamma-methyleneglutamine and its amide derivatives. Many of these l-gamma-methyleneglutamic acid amides were shown to be as efficacious as tamoxifen or olaparib at arresting cell growth among MCF-7 (ER+/PR+/HER2(-)), and SK-BR-3 (ER-/PR-/HER2(+)) breast cancer cells at 24 or 72 h of treatment. Several of these compounds exerted similar efficacy to olaparib at arresting cell growth among triple-negative MDA-MB-231 breast cancer cells by 72 h of treatment. None of the compounds inhibited cell growth in benign MCF-10A breast cells. Overall, N-phenyl amides and N-benzyl amides, such as 3, 5, 9, and 10, arrested the growth of all three (MCF-7, SK-BR-3, and MDA-MB-231) cell lines for 72 h and were devoid of cytotoxicity on MCF-10A control cells; N-benzyl amides with an electron withdrawing group at the para position, such as 5 and 6, inhibited the growth of triple-negative MDA-MB-231 cells commensurate to olaparib. These compounds hold promise as novel therapeutics for the treatment of multiple breast cancer subtypes.

Aza-heterocyclic frameworks through intramolecular pi-system trapping of spiro-N-acyliminiums generated from isoindolinone

Spiro-acetoxylactams as key substrates were obtained straightforwardly by the tandem regioselective reduction/O-acylation of spiro-isoindolinone-imides. The latter were produced in large scale in three steps from homophthalic acid. These imides were useful to provide in one step isoindolinones bearing hydroxymethyl-amide functions, tethered at quaternary carbon centre with promising biological issues. Submitted to Bronsted (TFA neat) and Lewis acid (trimethylsilyltrifluoro-methanesulfonic (TMSOTf) 10 mol%), the spiro-acetoxylactams undergo pi-cyclization of spiro-N-acyliminiums to provide diastereoselectively with pi-aromatic original pyrrolopyrido- and pyrroloazepino-isoindoles fused or not to aromatic systems. With pi-olefins, pyrrolopyridines and pyrrolo-azepines fused to isoindoline or containing amino-acids were isolated. A reaction mechanism producing all these systems is also discussed.

Sodium caseinate films modified using halloysite: Physicochemical characterization and drug permeability studies

Modification of sodium caseinate (SC) films by adding halloysite (HS) was investigated in this study. SC films with HS added in different ratios were prepared, and the physicochemical properties and drug permeability of the films were characterized. Acetaminophen was used as a model drug, and parabens served to evaluate the effect of the molecular weight of permeants through the films. This study revealed that SC could interact with HS through hydrogen bonding between the amine and amide groups of SC and the hydroxyl groups on the inner or outer tubular HS. The SC-HS films presented as continuous sheets and had a similar transparency as the SC films. The thermal stability of the SC films could be enhanced by adding HS. Incorporation of HS caused a reduction in puncture strength and elongation of the dry SC films, whereas strength enhancement of the we SC-HS films in acidic medium was found. The SC-HS films had lower water uptake and delayed drug permeation across the films in acidic medium. Moreover, the drug permeations across the SC and SC-HS films were dependent on the molecular weight or alkyl chain of parabens that impacted drug diffusion and partition processes through the films. The new knowledge obtained can be helpful for the development of film coating material based on SC-HS composites for modified-release tablets.

Pharmacophore modeling, 3D-QSAR, docking study and ADME prediction of acyl 1,3,4-thiadiazole amides and sulfonamides as antitubulin agents

Pharmacophore modeling, molecular docking, and in silico ADME studies have been carried out to determine the binding mode and drug likeliness profile of acyl 1,3,4-thiadiazole amides and sulfonamides as antitubulin agents. A four point pharmacophore model (AAHR.11) was generated using 63 compounds with IC50 values ranging from 3.16 to 505.76 mu M. A statistically significant 3D-QSAR model was generated from the pharmacophore hypothesis. The model had a high correlation coefficient (R-2 = 0.8925), cross validation coefficient (Q(2) = 0.8204) and F value (44.3) at 6 component PLS factor. The results of external validation indicated that the generated QSAR model possessed a high predictive power (R-2 = 0.83). The generated model also passed Tropsha’s test for predictive ability and Y-Randomisation test. The Domain of Applicability (APD) of the model was also successfully defined to ascertain that a given estimation can be considered reliable. Further, the restrictivity of the model was checked with inactive compounds by enrichment studies using the decoy test. In order to evaluate the effectiveness of the docking protocol, co-crystallized ligand was extracted from the ligand binding domain of the protein and was re-docked into the same position. The conformer obtained on re-docking and the co-crystallized ligand were superimposed and the RMSD between the two was found to be 0.853 angstrom. ADME predictions were also performed for these compounds. Outcomes of the present study have been first utilized to get insight into the molecular feature that promotes bioactivity, and then within screening procedure, have been exploited for the estimation of novel potential antitubulin compounds prior to their synthesis and biological tests.

Impaired beta cell sensitivity to incretins in type 2 diabetes is insufficiently compensated by higher incretin response

Background and aims: The incretin effect is impaired in type 2 diabetes (T2D), but the underlying mechanisms are only partially understood. We investigated the relationships between the time course of the incretin effect and that of glucose-dependent insulinotropic polypeptide (GIP) and glucagon-like peptide-1 (GLP-1) during oral glucose tolerance tests (OGTTs), thereby estimating incretin sensitivity of the beta cell, and its associated factors. Methods and results: Eight patients with T2D and eight matched subjects with normal glucose tolerance (NGT) received 25, 75, and 125 g OGTTs and corresponding isoglycemic glucose infusions (IIGI). The time course of the incretin effect, representing potentiation of insulin secretion by incretins (P-INCR), was determined by mathematical modelling as the time-dependent fold increase in insulin secretion during OGTT compared to IIGI. The time course of P-INCR was correlated with that of both GIP and GLP-1 in each subject (median r = 0.67 in NGT and 0.45 in T2D). We calculated an individual beta cell sensitivity to incretins (S-INCR) using a weighted average of GIP and GLP-1 (pooled incretin concentration, PIC), as the slope of the relationship between P-INCR and PIC. S-INCR was reduced in T2D (p < 0.01). In the whole group, mean PIC, GIP and GLP-1 concentrations during the OGTT were inversely correlated with SINCR, but T2D had lower PIC, GIP and GLP-1 levels at the same S-INCR (p < 0.05). Conclusion: Relative incretin insensitivity is partly compensated for by higher incretin secretory responses. However, T2D shows both impairment in incretin sensitivity and abnormal compensation by incretin secretion.
