Regulation of p42/p44 MAPK and p38 MAPK by the adenosine A(1) receptor in DDT1MF-2 cells

The mitogen-activated protein kinase (MAPK) family consists of the p42/p44 MAPKs and the stress-activated protein kinases, c-Jun N-terminal kinase (JNK) and p38 MAPK. We have previously reported that the human adenosine A(1) receptor stimulates p42/p44 MAPK in transfected Chinese hamster ovary cells. In this study, we have investigated whether the endogenous adenosine A(1) receptor in the smooth muscle cell line, DDT1MF-2 activates p42/p44 MAPK, JNK and p38 MAPK. The adenosine A(1) receptor agonist N-6-cyclopentyladenosine stimulated time and concentration-dependent increases in p42/p44 MAPK and p38 MAPK phosphorylation in DDT1MF-2 cells. No increases in JNK phosphorylation were observed following adenosine A(1) receptor activation. N-6-cyclopentyladenosine-mediated increases in p42/p44 MAPK and p38 MAPK phosphorylation were blocked by the selective adenosine A(1) receptor antagonist 1,3-dipropylcyclopentylxanthine and following pretreatment of cells with pertussis toxin. Furthermore, adenosine A(1) receptor-mediated increases in p42/p44 MAPK were sensitive to the MAPK kinase 1 inhibitor PD 98059 (2′-amino-3′-methoxyflavone), whereas p38 MAPK responses were blocked by the p38 MAPK inhibitor SE 203580 (4-(4-fluorophenyl)-2-(4-methylsulfinylphenyl)-5-(4-pyridyl)1H-imidazole). The broad range protein tyrosine kinase inhibitors genistein and tyrphostin A47 (alpha -cyano-(3,4-dihydroxy)thiocinnamide) did not block adenosine A(1) receptor stimulation of p42/p44 MAPK. For comparison, insulin-mediated increases in p42/p44 MAPK were blocked by genistein and tyrphostin A47. The Src tyrosine kinase inhibitor PP2 (4-amino-5-(4-chlorophenyl)-7-(t-butyl)pyrazolo[3,4-d]pyrimidine) and the epidermal growth factor receptor tyrosine kinase inhibitor AG1478 (4-(3-chloroanilino)-6,7-dimethoxyquinazoline) also had no effect on adenosine A(1) receptor stimulation of p42/p44 MAPK. Furthermore, the protein kinase C inhibitors Ro 31-8220 (3-{1-[3-(2-isothioureido)propyl]indol-3-yl}-4-(1-methylindol-3-yl)-3-pyrrolin-2,5-dione) chelerythrine and GF 109203X (2-[1-(3-dimethylaminopropyl)-1H-indol-3-yl]3-(1H-indol-3-yl)-maleimide) were without effect on adenosine A(1) receptor-induced p42/p44 MAPK phosphorylation. In contrast, wortmannin and LY 294002 (2-(4-morpholinyl)-8-phenyl-4H-1-benzopyran-4-one), inhibitors of phosphatidylinositol 3-kinase, attenuated adenosine A(1) receptor stimulation of p42/p44 MAPK phosphorylation. In conclusion, the adenosine A(1) receptor stimulates p42/p44 MAPK through a pathway which appears to be independent of tyrosine kinase activation but involves phosphatidylinositol 3-kinase. Finally, adenosine A(1) receptor stimulation in DDT1MF-2 cells also activated p38 MAPK but not JNK via a pertussis toxin-sensitive pathway. (C) 2001 Elsevier Science B.V. All rights reserved.

Influence of ultraviolet aging on the structure, mechanical and gas permeability properties of hydrogenated nitrile butadiene rubber

The effect of ultraviolet (UV) radiation on the structure and performance of hydrogenated nitrile butadiene rubber (HNBR) was studied in this paper. The HNBR was exposed to UV radiation for various durations (0, 7, 14, 21 and 28 days). The Fourier transform infrared spectroscopy (FTIR) results demonstrated that the surface molecular structures were oxidized to generate oxygenated species under UV radiation. The oxidative degree enhanced with the increase of aging time, resulting in thicker and denser cracks on the surface. The plausible aging mechanism of HNBR was suggested. The free volume of HNBR before and after UV aging was characterized by positron annihilation lifetime spectroscopy (PALS) and their cross-linking density, compression set, mechanical and gas permeability properties were also analyzed. In the first 14 days of UV irradiation, the dominant chain-scission reaction led to a decrease in cross-linking density of HNBR, resulting in the enhancement of free volume and thereby the increase of gas permeability. When the aging time was longer than 14 days, cross-linking reaction played a leading role and the free volume decreased, thus causing the reduction of gas permeability. As the aging time increased, the glass transition temperature (T-g), tensile strength and storage modulus of HNBR initially reduced and then increased, which was in agreement with the changing trend of cross-linking density.

A facile synthesis of 5-alkoxypyrrol-2(5H)-ones using a modified aza-Achmatowicz oxidation

An efficient approach to 2,4-disubstituted pyrroles has been uncovered and is based on an oxidative rearrangement of a furanyl carbamate followed by sequential reaction of the resulting 5-methoxypyrrol-2(5H)-one with various alkyl lithiates. The final step of the procedure involves heating the ring opened 1-methoxy-5-oxopentylcarbamate with a primary amine. The overall process can be carried out under mild conditions and complements existing methods to prepare 2,4-disubstituted pyrroles. (C) 2009 Elsevier Ltd. All rights reserved.

Enhanced thermal conductivity of carboxyl nitrile butadiene rubber composites with low-cost poly(catechol/polyamine) modified Al2O3 via biomimetic method

With the miniaturization, integration, and functionalization of the electronic components, heat dissipation in the electronic devices has become a challenging issue. Owing to high polarity, carboxyl nitrile butadiene rubber (XNBR) is usually employed as a dielectric material in the electronic devices. However, low thermal conductivity of XNBR hardly satisfies the increasingly stricter demands for heat dissipation. Herein, we used low-cost poly (catechol/polyamine) (PCPA) to modify Al2O3 nanoparticles via biomimetic method for enhancing the interfacial interaction between the Al2O3 filler and XNBR. The ortho-polyphenols in catechol were oxidized into orthoquinone groups in the alkaline solution. Then, the ortho-quinone groups formed a cross-linked structure to obtain PCPA via the Michael addition or Schiff base reaction with amine. The process decreased the interfacial thermal resistance and phonon scattering, resulting in an enhanced thermal conductivity. When the Al2O3-PCPA nanoparticles content was 30 vol%, the thermal conductivity of XNBR based composites reached up to 0.51 W/ mK, which was 3.19 times that of pure XNBR (0.16 W/mK). The proposed method has potential applications in large scale production of thermally conductive composites in industries, such as electronic packaging materials and thermal management materials.

Studies on the in vivo biotransformation of the tobacco alkaloid beta-nicotyrine

This paper reports the results of studies on the in vivo metabolic fate of the tobacco alkaloid 1-methyl-2-(3-pyridinyl)pyrrole (beta-nicotyrine) in New Zealand white rabbits. Two previously characterized metabolites, 5-hydroxy-1-methyl-5-(3-pyridinyl)-2-pyrrolidinone (5-hydroxycotinine) and 2-hydroxy-1-methyl-5-(3-pyridinyl)-3-pyrrolin-2-one, were present in low concentrations in the urine of the treated animals. The major urinary metabolite of beta-nicotyrine was identified as cis-3′-hydroxy-1-methyl-5-(3-pyridinyl)-2-pyrrolidinone (cis-3′-hydroxycotinine), the diastereoisomer of the major urinary metabolite of (S)-nicotine. The pathway leading to cis-3′-hydroxycotinine is proposed to proceed via autoxidation of 2-hydroxy-1-methyl-5-(3-pyridinyl)pyrrole, a postulated cytochrome P450-generated metabolite of beta-nicotyrine, followed by reduction of the carbon-carbon double bond present in the resulting 3-hydroxy-3-pyrrolin-2-one species. This proposal is supported by the in vivo biotransformation of 2-acetoxy-1-methyl-5-(3-pyridinyl)pyrrole, a latent form of the putative hydroxypyrrole intermediate, to cis-3′-hydroxycotinine. The in vivo conversion of 5-hydroxy-1-methyl-5-(3-pyridinyl)-3-pyrrolin-2-one to 5-hydroxycotinine is offered as evidence that supports the proposed reduction step.
