[pi 4+pi 2] cycloadditions of isothiazole derivatives

Dienophilic transformations of isothiazol-3(2H)-one 1,1-dioxides (1), I-oxides (IV), alpha,beta-unsaturated gamma-sultams (III), and cyclic vinyl p-tolylsulfilimines (X) in Diels-Alder reactions with acyclic and cyclic dienes, 1-aza-1,3-butadienes, furan and 1,3-oxazoles are briefly considered. Isothiazol-3(2H)-one 1,1-dioxides (1), 3-alkoxy- and 3-dialkylamino-isothiazole 1,1-dioxides (11) also readily undergo 1,3-dipolar cycloaddition with diazoalkanes, azides, nitrile imines, nitrile oxides, oxazolones and muenchnones. This reaction is characterized by high degree of regioselectivity.

PHARMACOLOGICAL CHARACTERIZATION OF RP-62203, A NOVEL 5-HYDROXYTRYPTAMINE 5-HT2 RECEPTOR ANTAGONIST

1 RP 62203 (2-[3-(4-(4-fluorophenyl)-piperazinyl)propyl]naphto[1,8-ca]isothiazole-1,1-dioxide) is a novel naphtosultam derivative which shows very high affinity for 5-HT2 receptors in the rat cerebral cortex (K(i) = 50.0 pM). 2 RP 62203 is relatively selective for this sub-type of 5-hydroxytryptamine (5-HT) receptor, having lower affinity for the 5-HT1A receptor and very low affinity for the 5-HT3 receptor. RP 62203 displayed low to moderate affinity for alpha(1)-adrenoceptors, dopamine D2 receptors and histamine H-1 receptors. 3 In vivo binding experiments demonstrated that oral administration of low doses of RP 62203 led to a long-lasting (> 6 h) occupation of cortical 5-HT2 receptors (ID50 = 0.39 mg kg-1). 4 In cortical slices from the neonatal rat, RP 62203 potently inhibited inositol phosphate formation evoked by 5-HT, with an IC50 of 7.76 nM. 5 The activity of neurones in the raphe and their responses to microiontophoretically applied 5-HT were studied with extracellular recording electrodes in the anaesthetized rat. RP 62203 potently and dose-dependently blocked excitations evoked by 5-HT when administered at doses of 0.5-4.0 mg kg-1, i.p. In contrast, neither 5-HT-evoked depressions nor glutamate-evoked excitations of raphe neuronal firing were blocked by RP 62203 at doses as high as 8.0 mg kg-1, i.p. 6 Head twitches induced by 1-(2,5-dimethoxy-4-iodophenyl)-2-aminopropane (DOI) could be abolished by low doses of RP 62203 in mice (ED50 = 0.44 mg kg-1, p.o.) and in rats (ED50 = 1.54 p.o.). Similar results were obtained with mescaline and 5-hydroxytryptophan (5-HTP). 7 The potency of RP 62203 was compared with that of three other 5-HT2 receptor antagonists, ritanserin, ICI 169,369 and ICI 170,809. In all models, RP 62203 showed similar activity to ritanserin, whilst either ICI 169,369 or ICI 170,809 was several fold less active. 8 It is concluded that RP 62203 is a potent and selective antagonist at 5-HT2 receptors in the rodent central nervous system.

Coordination chemistry of thiazoles, isothiazoles and thiadiazoles

Thiazole derived compounds have great potential in medicinal-and agro-chemistries, catalysis, cosmetic industry, corrosion protection, light harvesting, production of light-emitting diodes (LEDs), photochromes and molecular switches or nonlinear optical materials. In spite of that, not much attention has been paid to the coordination chemistry of this class of versatile and polyfunctional heterocyclic ligands. This review intends to systematize the existing information in this field and to highlight some perspectives in the synthesis and applications of 1,3-thiazole, isothiazole and thiadiazole metal complexes.

Synthesis and antiproliferative activity of benzo[d]isothiazole hydrazones

Several benzo[d]isothiazole hydrazones have been evaluated for their potential antiretroviral activity. Since a number of these compounds were found to be inactive against viruses, but showed cytotoxicity at micromolar concentrations against the human CD4(+) lymphocytes (MT-4) that were used to support HIV-1 growth, they were further tested for antiproliferative activity. The compounds resulted as being cytotoxic for MT-4 cells and new derivatives which were rationally designed and synthesized, were tested for antiproliferative activity against several leukaemia and solid, tumour cell lines. In addition, these compounds were evaluated against normal cell lines. Compound 2h proved to be the most active compound and the fragment -CO-NH-N=CH-2-hydroxyphenyl was identified as being very important for biological activity, suggesting intramolecular, hydrogen bond formation or favourable mutual disposition between two important centres in the pharmacophore. H-1-NMR spectra have been explained with the support of a conformational analysis. (c) 2006 Elsevier SAS. All rights reserved.

SYNTHESIS AND ANTIMICROBIAL AND ANTIOXIDANT ACTIVITIES OF SIMPLE SACCHARIN DERIVATIVES WITH N-BASIC SIDE CHAINS

A new class of N-basic side chains was obtained from 2,3-dihydro-2H-3-oxobenzo[d] isothiazole and aliphatic or aromatic aldehydes. Secondary amines (morpholine, N-methylpiperazine and ethyl isonipecotate) afforded tertiary N-basic side chains (4-6), while dibasic secondary amines (such as piperazine) gave bis-tertiary N-basic side chains (2). On the other hand, the use of mono-or dibasic primary amines namely; aniline, anisidine, phenyl hydrazine, o-hydroxy benzoic acid hydrazide, hydrazine hydrate, and ethylenediamine (instead of secondary amines) afforded secondary N-basic side chain as mono component or as bis component 7a-c, 9a-c, 11 and 12a-c. In addition, secondary Mannich base was synthesized via Michael addition to the corresponding aldimine. The new compounds were investigated for antioxidant and antimicrobial activities. Compounds 2, 7c and 12a exhibited significant antimicrobial activity, whereas compounds 7a, 7b, 9b, 9c and 11 exhibited high antioxidant activity as compared to ascorbic acid, These compounds showed the best protective effect against DNA damage induced by bleomycin.

Synthesis of Isothiazoles and Isoselenazoles through Rhodium-Catalyzed Oxidative Annulation with Elemental Sulfur and Selenium

A rhodium-catalyzed oxidative annulation of benzimidates with elemental sulfur for the direct construction of isothiazole rings is reported. The proposed reaction mechanism involving Rh(I)/Rh(III) redox is supported by a stoichiometric reaction of metallacycle species as well as DFT calculations. This method is also applicable to selenium cyclization to produce isoselenazole derivatives. The alkoxy substituent at C3 can be used for further functionalization of the azole core.

Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 35285-69-9, in my other articles.
