Elevation of arachidonoylethanolamide levels by activation of the endocannabinoid system protects against colitis and ameliorates remote organ lesions in mice

The endocannabinoid system (ECS) is a potential pharmaceutical target for the treatment of inflammatory bowel diseases (IBDs). The aim of this study was to explore the effects of activation of the ECS on IBD and the associated neural inflammation-induced disruption of the blood-brain barrier (BBB). In a mouse model of trinitrobenzene sulfonic acid-induced colitis, the inhibition of fatty acid amide hydrolase with URB597 elevated the arachidonoylethanolamide concentration of the colon. Macroscopic alterations of the colons were evaluated, and the 7-day survival rate of mice was analyzed. BBB integrity was assessed using a dye tracer method, and the cognitive function of mice was examined using a fear-conditioning test. URB597 treatment significantly reduced macroscopic alterations of the colon, decreased the mortality rate, and protected the integrity of the BBB in the mice (P<0.05). No significant changes were observed in the cognitive functions of the mice (P>0.05); therefore, the neuroprotective effect of ECS in this colitis model requires further investigation. Activation of the ECS was efficient in ameliorating colitis and increasing the survival rate of the mice, and reducing remote organ changes induced by colitis. The results suggest that modulation of the ECS is a potential therapeutic approach for IBDs and the associated remote organ lesions.

Does a Conjugation Site Affect Transport of Vitamin B-12-Peptide Nucleic Acid Conjugates into Bacterial Cells?

Gram-negative bacteria develop specific systems for the uptake of scarce nutrients, including vitamin B-12. These uptake pathways may be utilized for the delivery of biologically relevant molecules into cells. Indeed, it was recently reported that vitamin B-12 transported an antisense peptide nucleic acid (PNA) into Escherichia coli and Salmonella Typhimurium cells. The present studies indicate that the conjugation site of PNA to vitamin B-12 has an impact on PNA transport into bacterial cells. Toward this end, a specifically designed PNA oligomer has been tethered at various positions of vitamin B-12 (central Co, R-5 ‘-OH, c and e amide chains, meso position, and at the hydroxy group of cobinamide) by using known or newly developed methodologies and tested for the uptake of the synthesized conjugates by E. coli. Compounds in which the PNA oligonucleotide was anchored at the R-5 ‘-OH position were transported more efficiently than that of other compounds tethered at the peripheral positions around the corrin ring. Of importance is the fact that, contrary to mammalian organisms, E. coli also takes up cobinamide, which is an incomplete corrinoid. This selectivity opens up ways to fight bacterial infections.

Half-sandwich ruthenium complexes with oxygen-nitrogen mixed ligands as efficient catalysts for nitrile hydration reaction

Three ruthenium(II) p-cymene complexes containing oxygen-nitrogen mixed ligands [Ru(p-cymene)LCI] [HL = 2-(4,5-dihydrooxazol-2-yl)phenol (2a); HL = 2-(4,5-dihydrothiazol-2-yl)phenol (2b); HL = 2-(5,6-dihydro-4H-1,3-oxazin-2-yl)phenol (2c)] have been synthesized and characterized. All half-sandwich ruthenium complexes were fully characterized by H-1 and C-13 NMR spectra, elemental analyses and infrared spectrometry. The molecular structure of ruthenium complex 2c was further confirmed by single crystal X-ray diffraction methods. Furthermore, these half-sandwich ruthenium complexes are active catalysts for the hydration of nitriles to amides in the presence of sodium hydroxide in isopropanol. (C) 2017 Elsevier Ltd.

Burn-related Collagen Conformational Changes in ex vivo Porcine Skin using Raman Spectroscopy

This study utilizes Raman spectroscopy to analyze the burn-induced collagen conformational changes in ex vivo porcine skin tissue. Raman spectra of wavenumbers 500-2000 cm(-1) were measured for unburnt skin as well as four different burn conditions: (i) 200 degrees F for 10 s, (ii) 200 degrees F for the 30 s, (iii) 450 degrees F for 10 s and (iv) 450 degrees F for 30 s. The overall spectra reveal that protein and amino acids-related bands have manifested structural changes including the destruction of protein-related functional groups, and transformation from et-helical to disordered structures which are correlated with increasing burn severity. The deconvolution of the amide I region (1580-1720 cm(-1)) and the analysis of the sub-bands reveal a change of the secondary structure of the collagen from the alpha like helix dominated to the beta-aggregate dominated one. Such conformational changes may explain the softening of mechanical response in burnt tissues reported in the literature.

Limonia acidissima and Citrullus lanatus fruit seeds: Antimicrobial, thermal, structural, functional and protein identification study

An antimicrobial characterization along with thermal, structural, functional properties of L. acidissima and C. lanatus seeds were studied. Key proteins were identified in L. acidissima and C. lanatus seeds. The antimicrobial activity of L. acidissima protein hydrolysates was comparatively better than those of C. lanatus against the indicator strains used, i.e., Salmonella typhi, Pseudomonas aeruginosa, Escherichia coll. and Klebsiella pneumonia. The denaturation temperature for L. acidissima and C. lanatus protein hydrolysates were 92 and 72 degrees C, respectively. The FTIR analysis showed the presence of amide A, amide I, amide III and amide VI bands in the protein hydrolysates. The emulsifying activity index of the L. acidissima and C. lanatus seed protein hydrolysates were 53 and 29 m(2) /g, respectively. The emulsifying stability index for both hydrolysates was around 79%. The LCMS profile showed 4 proteins in L. acidisssima and 21 proteins in C. lanatus.

Backbone and ILVM methyl resonance assignments of human thymidylate synthase in apo and substrate bound forms

Human thymidylate synthase (hTS) is a 72 kDa homodimeric enzyme responsible for the conversion of deoxyuridine monophosphate (dUMP) to deoxythymidine monophosphate (dTMP), making it the sole source of de novo dTMP in human cells. As a result, hTS is an attractive anti-cancer therapeutic target. Additionally, hTS is known to possess a number of interesting biophysical features, including adoption of active and inactive conformations, positively cooperative substrate binding, half-the-sites activity, and interacting with its own mRNA. The physical mechanisms underlying these properties, and how they may be leveraged to guide therapeutic development, are yet to be fully explored. Here, as a preface to detailed NMR characterization, we present backbone amide and ILVM methyl resonance assignments for hTS in apo and dUMP bound forms. In addition, we present backbone amide resonance assignments for hTS bound to a substrate analog and the native cofactor.

Incorporation of norbornene moiety onto the arene of diaryl substituted amides through C-H functionalization

In the presence of norbornene, Pd(OAc)(2) smoothly catalyzed the meta-C-H activation process of N-phenylbenzamide (4) and yielded a norbornene fused product, (1R, 4S, 4aR, 8bS)-N-phenyl-1,2,3,4,4a, 8-bhexahydro-1,4-methanobiphenylene-5-carboxamide (5a). The employment of Ag(OAc) is crucial to the success of this reaction. Norbornene related compounds, dicyclopentadiene and norbordiene, were used as the reagents and structurally similar compounds, 5b and 5c were formed although with much lower yields. Similar reaction was carried out for using N-benzylbenzamide (9) as starting reagent. The resulted norbornene fused product (1R, 4S, 4aR, 8bS)-N-benzyl-1,2,3,4,4a, 8b-hexahydro-1,4-methanobiphenylene-5-carboxamide (10) shows that the C-H activation indeed took place at the phenyl ring of acetophenone part rather than the benzyl side. Crystal structures of 5a, 5c and 10 were determined by X-ray diffraction methods. A reaction mechanism is proposed to account for the formation of 5a, which could be extended to describe the generation of other structurally related compounds as well. (C) 2017 Elsevier B.V.
