Discovery of 3-hydroxy-3-pyrrolin-2-one-based mPGES-1 inhibitors using a multi-step virtual screening protocol

Targeting microsomal prostaglandin E-2 synthase-1 (mPGES-1) represents an efficient strategy for the development of novel drugs against inflammation and cancer with potentially reduced side effects. With this aim, a virtual screening was performed on a large library of commercially available molecules using the X-ray structure of mPGES-1 co-complexed with a potent inhibitor. Combining fast ligand-based shape alignment, molecular docking experiments, and qualitative analysis of the binding poses, a small set of molecules was selected for the subsequent steps of validation of the biological activity. Compounds 2 and 3, bearing the 3-hydroxy-3-pyrrolin-2-one nucleus, showed mPGES-1-inhibitory activity in the low micromolar range. These data highlighted the applicability of the reported virtual screening protocol for the selection of new mPGES-1 inhibitors as promising anti-inflammatory/anti-cancer drugs.

Base-catalyzed reaction between isatins and N-Boc-3-pyrrolin-2-one

The base-catalyzed reaction between isatins and N-Boc-3-pyrrolin-2-one yields Morita-Baylis-Hillman (MBH) adducts instead of the expected aldol products in good to high yields (up to 97%). Various organic and inorganic bases are efficient catalysts for this reaction. Our study excluded the Morita-Baylis-Hillman mechanism for the formation of the MBH-type products. The MBH products are most likely formed as a result of the subsequent isomerization of the original aldol products between isatins and N-Boc-3-pyrrolin-2-one. (C) 2013 Elsevier Ltd.

Catalytic hydrocyanation of alpha-ketoalkynes by Ni(CN)(2)/CO/KCN system in alkaline aqueous media: Identification of the active species

5-Hydroxy-3-pyrrolin-2-ones are regioselectively synthesized in a good yield under very mild conditions by tetracyanonickelate (0) ion catalyzed hydrocyanation of alpha-ketoalkynes, in the absence of hydrogen cyanide. The catalyst is prepared in situ in a basic aqueous medium by reduction of Ni(CN)(2) with CO in the excess of KCN. From the LR spectroscopy studies and by evaluation of catalytic activity of some cyanonickelates it is proposed that [Ni(CN)(4)](-4) anion is the active species in the process. A possible mechanism is suggested for the conversion of nickel cyanide to [Ni(CN)(4)](-4). The effect of the reaction variables, e.g.: reaction time, temperature, absorption of carbon monoxide, the concentration of potassium cyanide, water, substrate, and sodium hydroxide were also examined.

ZG-1494 alpha, a novel platelet-activating factor acetyltransferase inhibitor from Penicilium rubrum, isolation, structure elucidation and biological activity

A novel inhibitor of platelet-activating factor (PAF) acetyltransferase, an essential enzyme in the remodeling pathway of platelet-activating factor synthesis, was identified by a high throughput screen of natural product extracts of microbial origin. The compound, ZG-1494 alpha, was isolated from an ethyl acetate extract of a culture broth of Penicillium rubrum through bioassay guided fractionation. The structure of ZG-1494 alpha was determined by spectroscopic methods. A key feature of the structure, which is relatively rare among natural products, is the 5-hydroxy-3-pyrrolin-2-one moiety. A C-13-C-13 INADEQUATE was utilized to unambiguously determine the regiochemistry of this molecule.

Electroless Deposition of Ni-P Coatings on HNBR for Low Friction Rubber Seals

This paper reports a simple and cost-effective procedure to coat hydrogenated nitrile butadiene rubber (HNBR) with a well-adherent Ni-P film by using the electroless plating method. A HNBR surface functionalization process was first optimized, creating an interpenetrating network with polyvinylpyrrolidone (PVP). Silver nanoparticles were deposited on PVP and acted as catalysts for the Ni-P film deposition, eliminating the expensive tin-palladium sensitization/activation step. A homogeneous, low phosphorous Ni-P film was obtained after 60-120 min of plating in an alkaline bath, with an average thickness of 3 to 10 mu m, respectively. The PVP internetwork played an important role on the strong adhesion of the film, 1.0 +/- 0.5 MPa. The tribological behavior of Ni-P-plated HNBR samples was studied for 1, 5 and 10 N applied loads under dry sliding on a pin-on-disc configuration and the coefficient of friction (CoF) was reduced by similar to 30-49%, compared to uncoated HNBR (loads 1-5N). Based on these results, Ni-P-coated rubber can be regarded as a novel solution for enhancement of the tribological behavior of dynamic seals; it can be regarded as a means to avoid machinery failure. This method offers an alternative to the diamond-like carbon (DLC) coatings.

P5CS expression level and proline accumulation in the sensitive and tolerant wheat cultivars under control and drought stress conditions in the presence/absence of silicon and salicylic acid

The effects of silicon (Si) and salicylic acid (SA) applications on proline content and expression of (1)-pyrrolin-5-carboxylate synthetase (P5CS) were examined under different drought levels and different drought exposure times. Two wheat cultivars, a drought tolerant and a drought sensitive were used. The experiment was a factorial based on completely randomized design with three replicates. Expression analysis by the quantitative real time PCR showed that the tolerant cultivar had significantly higher P5CS expressions compared to the sensitive one under drought stress. In sampling time points, the maximum level of mRNA was observed at 48h after stress was applied. At 48h after stress induction, the expression of P5CS was almost 3.1 fold higher in the tolerant cultivar compared to the sensitive one. In both cultivars, gene expression decreased from 48 to 72h. The stressed plants treated with Si+SA showed a higher expression. Proline content started to increase by Si and SA treatments and the maximum proline content was obtained at simultaneous application of Si+SA. Drought stress significantly reduced chlorophyll content, relative water content and leaf water potential of both cultivars, while increased electrolyte leakage (EL) of the leaves. In contrast, foliar-applied Si and SA significantly increased these parameters and reduced EL, and the effect of simultaneous application of Si and SA was greater. The results suggest that the P5CS is a stress inducible gene. This gene has the potential to be used for improvement of drought stress tolerance in wheat. Network analysis highlighted positive interaction of osmotic stress, drought and cold stress on P5CS1 and the regulatory role of MYB2, ERF-1, and EIN3 transcription factors. In conclusion, alleviation of drought stress by application of Si and SA was associated partially with enhanced expression of P5CS gene and following proline accumulation.

Evaluating the efficacy of a newly developed palm-based process aid on nitrile rubber composites

The exploration of bio-based process aid is still ongoing in the effort to replace petroleum-based process oil. In this study, the efficacy of a newly developed palm-based process aid (Bio) on nitrile rubber (NBR) composites was investigated by varying its concentration from 0.0 to 10.0 phr. A comparison was made against a commercial oil (CO), i.e. naphthenic oil in terms of Mooney viscosity, cure characteristics, morphology, physical, and chemical properties. Results revealed that the use of Bio as process aid improves the processability of rubber by lowering the Mooney viscosity, enhancing filler dispersion, and lowering loss tangent values. Tensile properties and compression sets of CO-NBR composites were slightly better compared to Bio-NBR composites. Interestingly, Bio-NBR composites showed better ageing properties, especially at higher process aid content. Higher retentions of tensile strength and elongation at break and lower compression sets of aged Bio-NBR compared to CO-NBR composites were observed, which are possibly contributed by the good compatibility of Bio with aged rubber. Thermogravimetric analysis showed that the thermal stability of Bio-NBR composites were slightly better than CO-NBR composites. Based on these findings, the use of Bio (>= 7.5 phr) as process aid significantly improved the processability of rubber with some enhancement in ageing properties of composites that is desirable and ideal for various applications such as for the production of automotive components.
