Fused Isothiazole S-Oxide Systems from Cycloaddition Reactions of N-Benzylisothiazol-3-amine 1-Oxide

The racemic N-benzylisothiazol-3-amine 1-oxide (2) was demonstrated to be an efficient partner in Diels – Alder reactions (Schemes 2-4) and a good dipolarophile in 1,3-dipolar cycloaddition reactions with nitrile oxides (Scheme 5). Polycyclic isothiazole S-oxides with different substitution patterns were obtained from 2 in good yield and in a fully regioselective way. Improved diastereoselection was observed preforming the Diels – Alder or 1,3-dipolar cycloaddition reactions in H2O.

Electric Literature of 93-17-4, Consequently, the presence of a catalyst will permit a system to reach equilibrium more quickly, but it has no effect on the position of the equilibrium as reflected in the value of its equilibrium constant.I hope my blog about 93-17-4 is helpful to your research.

Naphtho[1,2-d]isothiazole acetic acid derivatives as a novel class of selective aldose reductase inhibitors

Acetic acid derivatives of naphtho[1,2-dlisothiazole (NiT) were synthesized and tested as novel aldose reductase (ALR2) inhibitors. The parent compound 11 exhibited a fair inhibitory activity (IC50 = 10 mu M), which was enhanced by 2 orders of magnitude by introducing a second carboxylic group at position 4 (13 and 14: IC50 = 0.55 and 0.14 mu M, respectively). Substitution of the acetic acid function with an apolar group gave inactive (29) or poorly active (25, 26, 30) compounds, thus demonstrating that the 2-acetic group is involved in the enzyme pharmacophoric recognition while the 4-carboxylic moiety has only an accessory role. The potent compounds 11, 13, 14, 26 all proved to be selective for ALR2, since none of them inhibited aldehyde reductase, sorbitol dehydrogenase, or glutathione reductase. The isopropyl. ester 31, a prodrug of 14, was found to be effective in preventing cataract development in severely galactosemic rats, when administered as an eyedrop solution. The theoretical binding mode of 13 and 14, obtained by docking simulations into the ALR2 crystal structure, was fully consistent with the structure-activity relationships in the NiT series.

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 93-17-4. Safety of 3,4-Dimethoxyphenylacetonitrile.

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.
