An Improved and Efficient Process for the Production of Highly Pure Paliperidone, a Psychotropic Agent, via DBU Catalyzed N-Alkylation

The present work describes an improved and efficient process for the synthesis of paliperidone (1), an antipsychotropic agent. The synthesis comprises the DBU (1,8-diazabicycloundec-7-ene) catalyzed N-alkylation of 3-(2-chloroethyl)-9-hydroxy-2-methyl-6,7,8,9-tetrahydro-4H-pyrido[1,2-a]-pyrimidin-4-one (5) with 6-fluoro-3-piperidin-4-yl-1,2 benzisoxazole hydrochloride (6) in methanol as the solvent and diisopropylamine as a base to yield paliperidone (1) with 85% yield and over 97% purity by HPLC. The present work also describes an industrially efficient purification process for the removal of critical process related impurities (8 and 9) in paliperidone (1). The process furnished 1 with an overall yield of about 60% and 99.85% purity.

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 127-17-3. Safety of 2-Oxopropanoic acid.

Medium Effects in Biologically Related Catalysis

Enzymes catalyze chemical reaction in aqueous media, but their active sites significantly differ in properties from water. In this chapter, the work on selected chemical reactions with important biological roles is reviewed to assess our current understanding of the effect of the environment that surrounds the reactive species. In particular, simple medium effects such as the ones provided by organic solvents, ionic liquids, and simple micelles are focused on. The findings that led to the computational design of enzymes that catalyze the Kemp elimination, a prototypical proton transfer reaction that has fascinated researchers for more than a century, are discussed.

Substrate Controlled Synthesis of Benzisoxazole and Benzisothiazole Derivatives via PhI(OAc)(2)-Mediated Oxidation Followed by Intramolecular Oxidative O-N/S-N Bond Formation

A phenyliodine(III) diacetate (PIDA)-mediated, highly efficient and tandem approach for the synthesis of aryldiazenylisoxazolo(isothiazolo)arenes from simple 2-amino-N’-arylbenzohydrazides has been developed. The reaction proceeds via formation of (E)-(2=aminoaryl)-(aryldiazenyl)methanone as the key intermediate, followed by intramolecular oxidative O-N/S=N bond formation in one pot at room temperature. The quiet different reactivity of the substrate is due to the formation of a diazo intermediate which encounters a nucleophilic attack by carbonyl oxygen on the electrophilic amine to produce isoxazole products, as compared to the previous reports(1a,b,4) in which an N-acylnitrenium ion intermediate is intramolecularly trapped by an amine group.

BENZISOXAZOLE-3-CARBOXAMIDE AND BENZISOTHIAZOLE-3-CARBOXAMIDE AS POTENTIAL ATYPICAL ANTIPSYCHOTIC AGENTS

A series of benzisoxazole- and benzisothiazole-3-carboxamides has been prepared and tested for potential antipsychotic activity. In general, the compounds showed an affinity for dopamine D-2 and serotonin 5HT(2A) and 5HT(1A) receptors. Several Members of this series have demonstrated activity in animal models predictive of potential antipsychotic activity. In addition, compounds 18, 19, 22, 27, 28, 43, and 44 have also shown a potential for reduced EPS liability as suggested by the ratio of activity seen in mesolimbic-mediated vs nigrostriatal-mediated behavioral assays.

Zonisamide suppresses the tonic phase but not the clonic phase of generalized seizures in developing rats

Zonisamide is increasingly used in pediatric neurology but there are no experimental data for immature animals. Zonisamide (12.5-100 mg/kg i.p.) was tested against pentetrazol-induced seizures in 7-, 12-, 18-, 25- and 90-day-old rats. Minimal clonic seizures were not suppressed by zonisamide. Selective suppression of tonic phase of generalized tonic-clonic seizures was demonstrated in all age groups. This effect indicates possible action of zonisamide against generalized tonic-clonic seizures during brain maturation. (C) 2010 Published by Elsevier B.V.

Involvement of mammalian liver cytosols and aldehyde oxidase in reductive metabolism of zonisamide

Zonisamide (1,2-benzisoxazole-3-methanesulfonamide) an anticonvulsant agent, is primarily metabolized to 2-sulfamoylacetyl-phenol by reductive cleavage of the 1,2-benzisoxazole ring. Rabbit liver cytosol with an electron donor of aldehyde oxidase exhibited a significant zonisamide reductase activity that was sensitive to inhibition by menadione, an inhibitor of aldehyde oxidase, The result suggested that the cytosolic activity is caused by aldehyde oxidase, a cytosolic enzyme. In fact, rabbit and rat liver aldehyde oxidase had the ability to reduce zonisamide when supplemented with its electron donor, Apparent K-M and V-max values of aldehyde oxidase for zonisamide were 217 mu M and 42 nmol/10 min/mg protein in the case of the rabbit liver enzyme, and 542 mu M and 382 nmol/10 min/mg protein in the case of the rat liver enzyme, respectively. In rabbits, hamsters, mice, and guinea pigs, zonisamide reductase activity of the liver cytosols with 2-hydroxypyrimidine, an electron donor of aldehyde oxidase, was much higher than that of the liver microsomes with NADPH. In rats, zonisamide reductase activity was examined with liver microsomes and cytosols from seven strains. The 2-hydroxypyrimidine-dependent cytosolic activity exhibited marked strain differences, unlike the NADPH-dependent microsomal activity, 1,2-Benzisoxazole was also reduced to salicylaldehyde by rabbit liver cytosol and aldehyde oxidase in the presence of 2-hydroxypyrimidine, Stoichiometric studies showed that 2-sulfamoylacetylphenol was formed accompanying nearly equimolar ammonia from zonisamide.

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 127-17-3, in my other articles.

Activation by zonisamide, a newer antiepileptic drug, of large-conductance calcium-activated potassium channel in differentiated hippocampal neuron-derived H19-7 cells

Zonisamide (ZNS; 3-sulfamoylmethyl-1,2-benzisoxazole), as one of the newer antiepileptic drugs, has been demonstrated its broad-spectrum clinical efficacy on various neuropsychiatric disorders. However, little is known regarding the mechanism of ZNS actions on ion currents in neurons. We thus investigated its effect on ion currents in differentiated hippocampal 19-7 cells. In whole-cell configuration of patch-clamp technology, the ZNS (30 mu M) reversibly increased the amplitude of K+ outward currents, and paxilline (1 mu M) was effective in suppressing the ZNS-induced increase of K+ outward currents. In inside-out configuration, ZNS (30 mu M) applied to the intracellular face of the membrane did not alter single-channel conductance; however, it did enhance the activity of large-conductance Ca2+-activated K+ (BKCa) channels primarily by decreasing mean closed time. In addition, the EC50 value for ZNS-stimulated BK Ca channels was 34 mu M. This drug caused a left shift in the activation curve of BK Ca channels, with no change in the gating charge of these channels. Moreover, ZNS at a concentration greater than 100 mu M also reduced the amplitude of A-type K+ current in these cells. A simulation modeling based on hippocampal CA3 pyramidal neurons (Pinsky-Rinzel model) was also analyzed to investigate the inhibitory effect of ZNS on the firing of simulated action potentials. Taken together, this study suggests that, in hippocampal neurons during the exposure to ZNS, the ZNS-mediated effects on BK Ca channels and A-type K+ current could be potential mechanisms through which it affects neuronal excitability.
