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.

Diarylheterocycle Core Ring Features Effect in Selective COX-1 Inhibition

The COX-1 isoenzyme plays a significant role in a variety of diseases, as it catalyzes the bioprocesses behind many health problems. Among the diarylheterocycle class of COX inhibitors, the isoxazole ring has been widely used as a central heterocycle for the preparation of potent and selective COX-1 inhibitors such as P6 [3-(5-chlorofuran-2-yl)-5-methyl-4-phenylisoxazole]. The role of the isoxazole nucleus in COX-1 inhibitor selectivity has been clarified by preparing a set of new diarylheterocycles with various heterocycle cores. Replacement of isoxazole with isothiazole or pyrazole gave a drastic decrease in COX-1 inhibitory activity, whereas the introduction of an electron-donating group (EDG) on the N-aryl pyrazole allowed recovery of COX-1 inhibitory activity and selectivity. The EDG-equipped 5-(furan-2-yl)-1-(4-methoxyphenyl)-3-(trifluoromethyl)-1H-pyrazole (17) selectively inhibits COX-1 activity (IC50=3.4 mu M; 28?% COX-2 inhibition at 50 mu M), in contrast to its inactive analogue, 3-(furan-2-yl)-1-phenyl-5-(trifluoromethyl)-1H-pyrazole, which does not bear the methoxy EDG. Molecular docking studies of compound 17 into the binding site of COX-1 shed light on its binding mode.

Molecular Docking and 3D QSAR Studies of Chk2 Inhibitors

Isothiazole-carboxamidines are potent ATP competitive checkpoint kinases (Chk2) inhibitors. Three-dimensional quantitative structure-activity relationship models were developed using comparative molecular field analysis and comparative molecular similarity indices analysis. The study was performed using three different geometrical methods. In geometrical method-1, molecules were fully optimized by PM3 Hamiltonian and aligned using common substructure. This alignment was subsequently used for Ligand-based comparative molecular field analysis and comparative molecular similarity indices analysis. In receptor-guided analyses, the receptor coordinates were obtained from public domine (PDB 2cn8). The molecule-7 was docked into receptor protein using FlexX and two plausible binding modes were identified. These modes were used as templates for geometrical method-2 and 3. These methods were used for 3D QSAR. The geometrical method-3-based comparative molecular field analysis (q (2) = 0.75, r (2) = 0.87 and r (2)(predict) = 0.81) and comparative molecular similarity indices analysis (q (2) = 0.90, r (2) = 0.96 and r (2)(predict) = 0.75) gave better result. The steric, hydrophobic and hydrogen bond donor fields effects significantly contribute to activity. In this way, the receptor-guided study presents a more detailed understanding about chk2 active site interactions. The study indicated some modifications to the active molecule which might be valuable to improve the activity.

Reactions of selected 3-bromoisothiazole-5-carbonitriles with the secondary dialkylamines pyrrolidine and morpholine

Readily available 3-bromoisothiazole-5-carbonitriles bearing various C-4 substituents [H, CO2R C N and halogen (CI or Br)], react with either pyrrolidine or morpholine to give, in most cases, the 3-amino-substituted derivatives in high yields. The reaction of 3-bromoisothiazole-4,5-dicarbonitrile, however, varied with the nucleophilicity of the dialkylamine: pyrrolidine led to cleavage of the isothiazole ring to give 2-[di(pyrrolidin-1-yl)methylene]malononitrile while morpholine led to the expected 3-(morpholin-4-yl)isothiazole-4,5-dicarbonitrile. By comparison, 3-chloroisothiazole-4,5-dicarbonitrile reacted with pyrrolidine to give surprisingly, 3-chloro-5-(pyrrolidin-1-yl)isothiazole-4-carbonitrile as the major product, while with morpholine the major product was the expected 3-(morpholin-4-yl)isothiazole-4,5-dicarbonitrile. The mechanisms of the transformations are discussed, together with rationalization for the formation of side products. Furthermore, the hydrolytic decarboxylation of methyl and ethyl esters of 3-dialkylaminoisothiazoles using both conventional heating and microwave irradiation is reported. (C) 2014 Elsevier Ltd.

AULOSIRAZOLE, A NOVEL SOLID TUMOR SELECTIVE CYTOTOXIN FROM THE BLUE-GREEN-ALGA AULOSIRA-FERTILISSIMA

Aulosirazole, the major cytotoxin in the blue-green alga (cyanobacterium) Aulosira fertilissima Ghose (UH strain DO-8-1), shows solid tumor selective activity in the Corbett assay. Its structure has been determined to be 5-hydroxy-3-methoxynaphtho[2,3-d]-1,2-thiazole-4,9-dione by a combination of spectroscopic, notably NMR, and X-ray crystallographic methods. The carbon skeleton and the juglone nature of 1 was determined by two-dimensional H-1-C-13 NMR correlation spectral analysis and one-dimensional C-13-C-13 decoupling experiments, the latter on the C-13-enriched cytotoxin. The presence of an isothiazole ring and the position of attachment for the juglone system was rigorously established by an X-ray crystallographic study.
