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.

ASYMMETRIC CATALYSIS .4. HYDROSILYLATION OF ACETOPHENONE WITH PYRROLINE-2,5-DIONE MODIFIED [RH(COD)CL](2) CATALYSTS

The reaction of dichloromaleimides with optically active amines affords chiral pyrrolin-2,5-diones. The diamines are C-13-NMR-spectroscopically characterized. In addition, the molecular structure of 1-(R)-menthyl-3-(R)-menthylamino-4-phenylamino-pyrrolin-2,5-dion (12) has been determined by X-ray crystallography. The pyrrolin-2,5-diones have been applied as planar, chiral N,N-ligands to modify the [Rh(COD)Cl](2) catalyst in the asymmetric hydrosilylation reaction of acetophenone. However, the optical induction observed for this reaction are poor for N,N-ligands as compared to the corresponding P,P-ligands.

Sequential activation of a-bonds : Intermolecular cascade annulation with migration and remote functionalization

We demonstrate a new catalytic property of the lanthanide compound CeCl3 center dot 7H(2)O which sequentially activates N-H, sp(2) C-H and sp(3) C-H sigma-bonds at ambient temperature. The powerful catalyst enables selective C-C and C-N bond-forming intermolecular cascade annulation between enamines and diary1-1,2-diketone to afford functionalized 3,3-diaryl-3-pyrrolin-2-ones involving migration of an aromatic ring. We have also initiated a new multicomponent strategy utilizing readily available and inexpensive precursors and environmentally benign CeCl3 center dot 7H(2)O as an efficient catalyst under benign reaction conditions towards direct synthesis of several N-heterocycles including pentasubstituted 2-pyrrolinones and pyrroles. These observations provide new prospects and perspectives in sigma-bond activation process for easy access to functional molecules.

Polymerization mechanism of 4-APN and a new catalyst for phthalonitrile resin polymerization

The widely used catalysts for phthalonitrile (PN) resin polymerization are aromatic compounds containing -NH2 because of their high catalytic performances. However, the catalytic mechanisms of these catalysts are not very clear. To understand the mechanisms of them, the widely used autocatalytic catalyst 4-(4-aminophenoxy)-phthalonitrile (4-APN) was studied in this paper. The polymerization process of 4-APN was tracked by a multi-purpose method, and ammonia gas was detected during the cross-linking processing for the fist time. Combined with the online IR results of the curing process of 4-APN, the mechanism of ammonia generation was newly proposed. Based on this mechanism, a new catalyst selection strategy was promoted, which is different from the traditional approach to catalyst selection for PN resin polymerization. According to the new strategy, 1,3-diiminoisoindoline (1,3-DII) was selected as a novel catalyst. The results showed that the new catalyst could not only effectively catalyze the polymerization of PN resin, but also has a lower curing temperature than that of organic amine catalysts and can eliminate the release of ammonia gas and the voids in the products caused thereby. Therefore, the results of this study will give important enlightenment to the development of PN catalysts and the development of PN.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 256-96-2. Category: pyrrolines.

Synthesis of the 26-Membered Core of Thiopeptide Natural Products by Scalable Thiazole-Forming Reactions of Cysteine Derivatives and Nitriles

The increased resistance of bacteria to clinical antibiotics is one of the major dilemmas facing human health and without solutions the problem will grow exponentially worse. Thiopeptide natural products have shown promising antibiotic activities and provide an opportunity for the development of a new class of antibiotics. Attempts to directly translate these compounds into human medicine have been limited due to poor physiochemical properties. The synthesis of the core structure of the 26-membered class of thiopeptide natural products is reported using chemistry that enables the synthesis of large quantities of synthetic intermediates and the common core structure. The use of cysteine/nitrile condensation reactions followed by oxidation to generate thiazoles has been key in enabling large academic scale reactions that in many instances avoided chromatography further aiding in accessing large amounts of key synthetic intermediates.
