Direct computation of the pi-current density, that is, the ‘ring current’, of anthranil (1) and its isomers 1,2-benzisoxazole (2) and benzoxazole (3) reveals different patterns of current flow: isomers 2 and 3 sustain strong benzene-like currents in the six-membered and bifurcated flow in the five-membered ring, whereas, in keeping with its lower thermodynamic stability, 1 has only a perimeter circulation without separate monocycle currents. Although the ring current criterion does not offer a sharp distinction between 2 and 3, their difference in thermodynamic stability is identical to that between isoxazole (4) and oxazole (5) suggesting an aromaticity order 1 < 2 approximate to 3.

The catalytic antibody 21D8 efficiently catalyzes the decarboxylation of a substituted 3-carboxybenzisoxazole-a simple, unimolecular reaction that is not susceptible to general acid/base catalysis but that is highly sensitive to the microenvironment. The transition-state structure of this decarboxylation reaction has been probed by measuring the carbon kinetic isotope effect for the uncatalyzed decarboxylation in water and for the dioxane-accelerated and antibody-catalyzed reactions. The isotope effect for the decarboxylation of 5-nitro-3-carboxybenzisoxazole is k12/k13 = 1.046 in aqueous buffer at 20-degrees-C and 1.048 for the antibody-catalyzed reaction. With increasing dioxane in the reaction medium, the rate of the spontaneous decarboxylation increases by almost four orders of magnitude, whereas the isotope effect displays only a slight, progressive decrease to k12/k13 = 1.043 in 100% dioxane. Together, these results indicate that the structure of the transition state undergoes very little change in spite of > 10(4)-fold increases in the rate of the reaction caused by solvation of the substrate by organic solvents or the low dielectric environment of the antibody active site.

The utility of the nitrogen extrusion reaction of azido complexes, generated in situ from the corresponding aldehydes or ketones with TMSN3 in the presence of ZrCl4 or TfOH, has been described. These azido complexes could undergo three different pathways, depending on the substrates. First, azido methanolate complexes or imine diazonium ions could lead to benzisoxazole products via an intramolecular nucleophilic substitution. Second, imine diazonium ions could also undergo either the elimination of proton to provide nitrile products in good to excellent yields or an aryl migration, followed by an intramolecular nucleophilic addition, to give benzoxazole products in good yields.

The acid/base-catalysed Kemp elimination of 5-nitro-benzisoxazole forming 2-cyano-4-nitrophenol has long served as a design platform of enzymes with non-natural reactions, providing new mechanistic insights in protein science. Here we describe an alternative concept based on redox catalysis by P450-BM3, leading to the same Kemp product via a fundamentally different mechanism. QM/MM computations show that it involves coordination of the substrate’s N-atom to haem-Fe(II) with electron transfer and concomitant N-O heterolysis liberating an intermediate having a nitrogen radical moiety Fe(III)-N-center dot and a phenoxyl anion. Product formation occurs by bond rotation and H-transfer. Two rationally chosen point mutations cause a notable increase in activity. The results shed light on the prevailing mechanistic uncertainties in human P450-catalysed metabolism of the immunomodulatory drug leflunomide, which likewise undergoes redox-mediated Kemp elimination by P450-BM3. Other isoxazole-based pharmaceuticals are probably also metabolized by a redox mechanism. Our work provides a basis for designing future artificial enzymes.

Chemistry, like all the natural sciences, begins with the direct observation of nature— in this case, of matter. 636-61-3, Name is (R)-2-Hydroxysuccinic acid, SMILES is O=C(O)[C@H](O)CC(O)=O, in an article , author is KANBA, S, once mentioned of 636-61-3, SDS of cas: 636-61-3.

1 Zonisamide, an anticonvulsant developed in Japan, is structurally similar to serotonin. Zonisamide has been proven to have a pharmacological profile that is very similar to that of carbamazepine. Thus, the effect of zonisamide was examined in 24 psychiatric patients: 15 with bipolar manic state, 6 with schizoaffective manic state, and 3 schizophrenic excitement. 2 Approximately 25% of all the patients and 33% of the bipolar manic patients showed remarkable global improvement with the addition of zonisamide. Approximately 71% of all the patients and 80% of the bipolar group had more than moderate global improvement. 3 No serious adverse reactions were found and no patients required zonisamide withdrawal. One patient developed both leukocytosis and mildly abnormal liver function test. One developed leukocytosis and another reported mild sleepiness. These reactions disappeared when zonisamide was discontinued.

Paliperidone (9-hydroxyrisperidone), the primary active metabolite of risperidone, is a benzisoxazole derivative of the second-generation antipsychotics. Paliperidone patmitate or PP (the patmitate ester of paliperidone) is available as a once-daily oral tablet, a once-monthly injection or PP1M, and a 3-monthly injection or PP3M (marketed under the name of Trevicta (R) in the European Union). Despite the recent availability of PP3M, several cases of intoxication have been reported worldwide, including lethal cases. However, in Europe, no case of fatal poising has been reported to date. A 33-year-old man was found dead in his room at his parents’ home. His only medical background was a history of schizophrenia. The external examination was without any particularity except a runny nose of brownish liquid with an alcoholic smell. Given the context and the tack of evidence of a third party intervention, an autopsy was not considered necessary. Toxicological analysis of right femoral blood highlighted the presence of paliperidone (240 mu g/ L) only. The risk associated with the use of PP3M formulation is still imperfectly evaluated and several cases of intoxication have been reported worldwide, including fatal cases. In this case, paliperidone poisoning appears to be the highly likely cause of death. In fact, the blood concentration of paliperidone is high, twice the toxicity threshold used in therapeutic monitoring, and no other substances have been identified. This case highlights: the necessity to always evaluate the benefit-risk balance when prescribing this sustained-release form of paliperidone and the difficulties in interpreting paliperidone concentration in forensic cases.

A series of hydrophobically and electrostatically modified polyacrylamides (Copol(AM-C12)) has been synthesized by radical-initiated copolymerization of acrylamide with n-dodecylmethyldiallylammonium bromide as the hydrophobe in aqueous solution using ammonium persulfate as the initiator. The formation of hydrophobic microdomains of the copolymers was revealed by large hypsochromic shifts of the long-wavelength absorption band of the solvatochromic probe Methyl Orange, noncovalently bound to the macromolecule. It was found that the microdomains formed by these copolymers in aqueous solution are more hydrophobic than those of the cationic polysoaps poly(alkylmethyldiallylammonium halides) containing the same n-dodecyl groups as the side chains as a result of the reduced electrostatic repulsions at the periphery of the microdomains. The reduced cationic character of the copolymers Copol(AM-C12) most likely also accounts for the observation that the anionic dye Methyl Orange does not; induce microdomain formation in aqueous solution. The effect of the hydrophobically and electrostatically modified polyacrylamides on the unimolecular decarboxylation of 6-nitrobenzisoxazole-3-carboxylate anion (6-NBIC) has been investigated in aqueous solutions at pH 11.3 and 30 degrees C. It is suggested that the relatively modest catalytic effects induced by Copol(AM-C12) should be ascribed to hydrogen-bond stabilization of the initial state by NH groups in the macromolecules. The decarboxylation rates of 6-NBIC at binding sites in hydrophobic microdomains increase with increasing n-dodecyl group content in the copolymers.

Heat shock protein 90 (Hsp90) is a molecular chaperone that is responsible for activating many signaling proteins and is a promising target in tumor biology. We have identified small-molecule benzisoxazole derivatives as Hsp90 inhibitors. Crystallographic studies show that these compounds bind in the ATP binding pocket interacting with the Asp93. Structure based optimization led to the identification of potent analogues, such as 13, with good biochemical profiles.
