Synthesis of Indole and Oxindole Derivatives Incorporating Pyrrolidino, Pyrrolo Or Imidazolo Moieties
From DEPARTMENT OF BIOSCIENCES AT NOVUM Karolinska Institutet, Stockholm, Sweden SYNTHESIS OF INDOLE AND OXINDOLE DERIVATIVES INCORPORATING PYRROLIDINO, PYRROLO OR IMIDAZOLO MOIETIES Stanley Rehn Stockholm 2004 All previously published papers have been reproduced with permission from the publishers. Published and printed by Karolinska University Press Box 200, SE-171 77 Stockholm, Sweden © Stanley Rehn, 2004 ISBN 91-7140-169-5 Till Amanda Abstract The focus of this thesis is on the synthesis of oxindole- and indole-derivatives incorporating pyrrolidins, pyrroles or imidazoles moieties. Pyrrolidino-2-spiro-3’-oxindole derivatives have been prepared in high yielding three-component reactions between isatin, α-amino acid derivatives, and suitable dipolarophiles. Condensation between isatin and an α-amino acid yielded a cyclic intermediate, an oxazolidinone, which decarboxylate to give a 1,3-dipolar species, an azomethine ylide, which have been reacted with several dipolarophiles such as N- benzylmaleimide and methyl acrylate. Both N-substituted and N-unsubstituted α- amino acids have been used as the amine component. 3-Methyleneoxindole acetic acid ethyl ester was reacted with p- toluenesulfonylmethyl isocyanide (TosMIC) under basic conditions which gave (in a high yield) a colourless product. Two possible structures could be deduced from the analytical data, a pyrroloquinolone and an isomeric ß-carboline. To clarify which one of the alternatives that was actually formed from the TosMIC reaction both the ß- carboline and the pyrroloquinolone were synthesised. The ß-carboline was obtained when 3-ethoxycarbonylmethyl-1H-indole-2-carboxylic acid ethyl ester was treated with a tosylimine. An alternative synthesis of the pyrroloquinolone was performed via a reduction of a 2,3,4-trisubstituted pyrrole obtained in turn by treatment of a vinyl sulfone with ethyl isocyanoacetate under basic conditions. -
Effects of Phosphodiesterase Inhibitors on Human Lung Mast Cell and Basophil Function
British Journal of Pharmacology (1997) 121, 287 ± 295 1997 Stockton Press All rights reserved 0007 ± 1188/97 $12.00 Eects of phosphodiesterase inhibitors on human lung mast cell and basophil function Marie C. Weston, Nicola Anderson & 1Peter T. Peachell Department of Medicine & Pharmacology, University of Sheeld, Royal Hallamshire Hospital (Floor L), Glossop Road, Sheeld S10 2JF 1 The non-hydrolysable cyclic AMP analogue, dibutyryl (Bu2)-cyclic AMP, inhibited the stimulated release of histamine from both basophils and human lung mast cells (HLMC) in a dose-dependent manner. The concentrations required to inhibit histamine release by 50% (IC50) were 0.8 and 0.7 mM in basophils and HLMC, respectively. The cyclic GMP analogue, Bu2-cyclic GMP, was ineective as an inhibitor of histamine release in basophils and HLMC. 2 The non-selective phosphodiesterase (PDE) inhibitors, theophylline and isobutyl-methylxanthine (IBMX) inhibited the IgE-mediated release of histamine from both human basophils and HLMC in a dose-dependent fashion. IBMX and theophylline were more potent inhibitors in basophils than HLMC. IC50 values for the inhibition of histamine release were, 0.05 and 0.2 mM for IBMX and theophylline, respectively, in basophils and 0.25 and 1.2 mM for IBMX and theophylline in HLMC. 3 The PDE 4 inhibitor, rolipram, attenuated the release of both histamine and the generation of sulphopeptidoleukotrienes (sLT) from activated basophils at sub-micromolar concentrations but was ineective at inhibiting the release of histamine and the generation of both sLT and prostaglandin D2 (PGD2) in HLMC. Additional PDE 4 inhibitors, denbufylline, Ro 20-1724, RP 73401 and nitraquazone, were all found to be eective inhibitors of mediator release in basophils but were ineective in HLMC unless high concentrations (1 mM) were employed. -

Phosphodiesterase (PDE)
Phosphodiesterase (PDE) Phosphodiesterase (PDE) is any enzyme that breaks a phosphodiester bond. Usually, people speaking of phosphodiesterase are referring to cyclic nucleotide phosphodiesterases, which have great clinical significance and are described below. However, there are many other families of phosphodiesterases, including phospholipases C and D, autotaxin, sphingomyelin phosphodiesterase, DNases, RNases, and restriction endonucleases, as well as numerous less-well-characterized small-molecule phosphodiesterases. The cyclic nucleotide phosphodiesterases comprise a group of enzymes that degrade the phosphodiester bond in the second messenger molecules cAMP and cGMP. They regulate the localization, duration, and amplitude of cyclic nucleotide signaling within subcellular domains. PDEs are therefore important regulators ofsignal transduction mediated by these second messenger molecules. www.MedChemExpress.com 1 Phosphodiesterase (PDE) Inhibitors, Activators & Modulators (+)-Medioresinol Di-O-β-D-glucopyranoside (R)-(-)-Rolipram Cat.

Xagrid, INN-Anagrelide
SCIENTIFIC DISCUSSION 1. Introduction Anagrelide hydrochloride monohydrate is a novel imidazoquinazoline originally developed as an inhibitor of platelet aggregation but subsequently found to have value as a platelet-lowering agent for the treatment of patients suffering from Essential thrombocythaemia (ET). ET is one of a number of chronic myeloproliferative disorders characterised by an elevated platelet count due to an autonomous clonal proliferation of bone marrow megakaryocytes. The underlying cause of this proliferation is unknown. Platelet function is generally normal and the cells are able to undergo aggregation and to participate in the haemostatic process in a more or less normal manner. The diagnosis is one of exclusion of reactive causes and other myeloproliferative disorders (MPDs) according to internationally agreed criteria of the Polycythaemia Vera Study Group (PVSG). The main criterion is a sustained platelet level of >600 x 109/L for more than two months. It is estimated that the prevalence of ET in the European Union (EU) is 2-3 per 10,000 persons. ET is a condition that may affect anyone at any stage of life from childhood although the median age of presentation is 60 years. Literature and clinical experience indicate a preponderance of female patients between the ages of 25 and 50 years. Up to two thirds of patients with ET are asymptomatic and a significant number of patients are now being diagnosed as an incidental consequence of the analysis of full blood counts for other health reasons. Generally, the older patient is more likely to be symptomatic at presentation, although younger patients may present with major complications.
