Biocatalysis of isomerization of 1,2-benzisoxazole by bovine serum albumin in an organic solvent

The catalytic properties of bovine serum albumin (BSA) have been studied rather extensively. The protein has shown catalytic activities toward a variety of reactions in aqueous media. However, there appears to be no reports of reactions catalyzed exclusively in organic media. In this study, we report the catalytic property of BSA on the isomerization of 1,2-benzisoxazole in an organic solvent. Kinetics were performed using a continuous flow system in a spectrophotometer at 330 rim. The catalysis showed a Michaells-Menten behavior with an estimated catalytic, efficiency (k(cat)/K-M) of 8.77 M-1S-1. The influence of water content and inhibitors was also studied. The activity of BSA in acetonitrile is approximately 20% of that in water under similar conditions. Inhibition studies show that the active site may be the pyridoxal binding site involving Lys-220.

Catalytic Asymmetric Hydrogenation of 3-Substituted Benzisoxazoles

A variety of 3-substituted benzisoxazoles were reduced with hydrogen using the chiral ruthenium catalyst, {RuCl(p-cymene)[(R,R)-(S,S)-PhTRAP]}Cl. The ruthenium-catalyzed hydrogenation proceeded in high yield in the presence of an acylating agent, affording alpha-substituted o-hydroxybenzylamines with up to 57% ee. In the catalytic transformation, the N-O bond of the benzisoxazole substrate is reductively cleaved by the ruthenium complex under the hydrogenation conditions. The C-N double bond of the resulting imine is saturated stereoselectively through the PhTRAP-ruthenium catalysis. The hydrogenation produces chiral primary amines, which may work as catalytic poisons, however, the amino group of the hydrogenation product is rapidly acylated when the reaction is conducted in the presence of an appropriate acylating agent, such as Boc(2)O or Cbz-OSu.

A PHARMACOLOGICAL, PHARMACOKINETIC AND CLINICAL OVERVIEW OF RISPERIDONE, A NEW ANTIPSYCHOTIC THAT BLOCKS SEROTONIN 5-HT2 AND DOPAMINE D-2 RECEPTORS

Risperidone is a benzisoxazole derivative with antipsychotic activity that is chemically unrelated to other currently available antipsychotic agents, Its neuropharmacological properties, characterized by potent central antagonism of both serotonin 5-HT2 and dopamine D-2 receptors, also differ from those of most other antipsychotic drugs, The pharmacokinetics of risperidone are well understood, having been studied in healthy subjects as well as in psychotic patients. The absolute oral bioavailability of risperidone is nearly 70%, and after oral administration, it is rapidly absorbed with the plasma level reaching a peak at about 1 h. 9-Hydroxyrisperidone, one of the metabolites of risperidone, is equally active with the parent compound and so the clinical activity of a dose of risperidone is due to the combined actions of both moieties, The plasma concentrations of risperidone and its active metabolite remain dose proportional even at doses exceeding the therapeutic range. In clinical trials with chronic schizophrenia patients, risperidone has an overall therapeutic activity comparable with that of haloperidol, but at doses that produce similar improvements in the positive symptoms of schizophrenia, risperidone has a greater effect on the negative symptoms and produces less extrapyramidal side effects than does haloperidol, However, additional controlled clinical studies are needed before the claims that risperidone is therapeutically superior to haloperidol cah be considered to be established firmly, Although risperidone is effective in acute schizophrenia and in non-treatment-resistant schizophrenics, studies adequately comparing risperidone with clozapine in treatment-resistant schizophrenic patients remain to be published. In addition, risperidone has been reported to be of value in patients with schizodepressive disorders, The clinical success of risperidone suggests that the development of compounds with selective affinity for 5-HT2 or other serotonin receptors may result in even further improvements in the pharmacotherapy of psychiatric disorders.

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 427-49-6. Safety of alpha-Cyclopentylmandelic Acid.

EFFECT OF 1,2-BENZISOXAZOLE-3-ACETIC ACID ON PLANT-REGENERATION FROM PROTOPLASTS OF NICOTIANA-TABACUM

Benzisoxazole-3-acetic acid, a new synthetic growth regulator, was administered to protoplast cultures from Nicotiana tabacum and subsequently to the developed microcalluses, to test its activity on plant regeneration from protoplasts in different culture conditions. Such activity, compared to that of naphthalene-acetic acid, proved to be rather low in the stage of cellular division and microcallus formation but particulary high in the stage of shoot induction from microcallus, thus confirming that the activity of this compound is mainly morphogenetic.

EXAMINATION OF THE D(2)/5-HT(2) AFFINITY RATIOS OF RESOLVED 5,6,7,8,9,10-HEXAHYDRO-7,10-IMINOCYCLOHEPT[B]INDOLES – AN ENANTIOSELECTIVE APPROACH TOWARD THE DESIGN OF POTENTIAL ATYPICAL ANTIPSYCHOTICS

Enantiomers of several N-substituted 5,6,7,8,9,10-hexahydro-7,10-iminocyclohept[b]indoles were obtained by the resolution of 2-fluoro-5,6,7,8,9,10-hexahydro-7,10-iminocyclohept[b]indole and 5,6,7,8,9,10-hexahydro-7,10-iminocyclohept[b]indole followed by N-alkylation. These, as well as the racemates, were evaluated for their affinity for the 5-HT2 and D2 receptors. Those compounds possessing the 7S,10R stereochemistry were consistently recognized by the 5-HT2 and D2 receptors as the eutomer. 2-Fluoro-11-[4-(4-fluorophenyl)-4-oxobutyl]-5,6,7,8,9,10-hexahydro-7S,10R-iminocyclohept[b]indole [(7S,10R)-8] had the highest affinity for the 5-HT2 receptor (K(i) = 0.80 nM), while its distomer (7R,10S)-8 was the most selective member of this class of bridged gamma-carbolines (D2/5-HT2 = 562). Incorporation of a benzoyl or isosteric benzisoxazole moiety tethered by a four-carbon spacer to a bridged gamma-carboline nucleus, possessing the 7S,10R absolute configuration, produced high affinity ligands for the 5-HT2 and D2 receptors.

Design and synthesis of amino acids-conjugated heterocycle derived ureas/thioureas as potent inhibitors of protein glycation

Protein glycation is believed to play an important role in the development of long-term disorders associated with diabetic complications. In view of the wide occurrence of advanced glycation end products (AGE’s) and the oxidative stress derived from them in a variety of diabetic complications, it would be of great interest to identify and develop AGE inhibitors. In this study, synthesis and in vitro antiglycation activity of a small library of forty urea/thiourea derivatives of Phe/Tyr/Glu/Lys-benzisoxazole hybrids are reported. Structures of the compounds were confirmed by IR, NMR, mass spectrometry, and elemental analysis. Most of the title compounds exhibited promising activity. Best antiglycation activity was found for Tyr analogue with methoxy group as a substituent particularly at the para position with IC50 value of 1.9 mu M against the positive control, Rutin, with IC50 = 41.9 mu M. Thus, the title compounds represent novel class of potent antiglycating agents.

Therapeutic effects of zonisamide and some conventional antiepileptic drugs on amygdaloid kindling in rats

In this study, we compared the anticonvulsive effects of zonisamide (ZNS) with those of phenytoin (PHT), carbamazepine (CBZ) and phenobarbital (PB) in amygdaloid (AM)-kindled rats. Electrodes were implanted into the left AM of adult male Wistar rats. The animals were kindled at the afterdischarge (AD) threshold. After the completion of kindling, the generalized seizure triggering threshold was determined. The drugs were administered intraperitoneally in animals that showed stable generalized convulsions at near-threshold stimulation. Immediately after each drug trial, venous blood was sampled and the serum drug concentration was measured using EMIT or HPLC. All the drugs suppressed secondary generalization at lower doses, and further regressed the seizure stage and reduced the AD duration at higher doses. Higher doses of all drugs except ZNS, however, produced motor ataxia or lethargy. Thus, ZNS seemed to have a wider therapeutic range than other conventional antiepileptic drugs. An additional experiment on the effects of ZNS against supra-threshold stimulation suggested that a major action of ZNS in the kindling model is to attenuate the seizure spread rather than to elevate the AD threshold at the focus.

ZONISAMIDE REDUCES HYPOXIC-ISCHEMIC BRAIN-DAMAGE IN NEONATAL RATS IRRESPECTIVE OF ITS ANTICONVULSIVE EFFECT

The neuroprotective effect of a novel anticonvulsant, zonisamide, was investigated in neonatal rats with hypoxic-ischemic brain damage. Rats underwent left carotid ligation followed by hypoxic exposure (8% 0(2)) for 2.5 h. When zonisamide (75 mg/kg) was administered i.p. 1 h before hypoxia, it reduced the cortical infarction volume to 6 +/- 5% (mean +/- S.E.M.) from 68 +/- 7% in vehicle-treated controls and the striatal volume to 8 +/- 4% from 78 +/- 7%. Zonisamide also reduced neuronal necrosis in 5 hippocampal regions (the dentate gyrus, CA4, CA3, CA1, and the subiculum). The plasma zonisamide concentration before and after hypoxia was 47.9 +/- 2.0 mu g/ml and 42.3 +/- 3.9 mu g/ml, respectively. Epidural electrodes were implanted in 6 pups one day before hypoxia-ischemia. Electroencephalograms were recorded during hypoxia-ischemia in rats given zonisamide or vehicle before the insult. The intensity of seizure activities was similar in the zonisamide-treated pups and the vehicle-treated controls. These findings demonstrate that zonisamide reduces neonatal hypoxic-ischemic brain damage and that this protective effect does not depend on its anticonvulsant action.

Artificial enzymes based on imprinted liquid-crystalline materials

Liquid-crystal elastomers, imprinted around indole, are assessed as artificial enzymes for the isomerisation of benzisoxazole into 2-cyano phenol. Two types of material are synthesised, tested in the catalysis and compared with non-liquid-crystal imprinted polymers: an imprinted liquid-crystalline elastomer and a semi-interpenetrated imprinted liquid-crystal network. The catalytic effect of all materials is close. However, the main benefit for the liquid-crystal elastomer is shown to be the shape memory of the material at the molecular scale, because the isomerisation kinetics are found to be identical before and after deformation of the cavities either by thermal treatment up to the isotropic state or by solvent induced swelling. This fact is related to the coupling between the order and the conformation of the polymer chains, which is fixed by the crosslinking process. On the other hand, the imprinted sites of the semi-interpenetrated imprinted liquid-crystal elastomer are shown to be almost 100 times more active than the non-imprinted sites in the catalysis. This factor is only 22 for the corresponding non-liquid-crystalline network.
