SYNTHESIS OF HYDROPHOBICALLY AND ELECTROSTATICALLY MODIFIED POLYACRYLAMIDES AND THEIR CATALYTIC EFFECTS ON THE UNIMOLECULAR DECARBOXYLATION OF 6-NITROBENZISOXAZOLE-3-CARBOXYLATE ANION

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.

Discovery of benzisoxazoles as potent inhibitors of chaperone heat shock protein 90

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.

THE 1ST OPEN STUDY OF ZONISAMIDE, A NOVEL ANTICONVULSANT, SHOWS EFFICACY IN MANIA

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.

A redox-mediated Kemp eliminase

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.

CARBON KINETIC ISOTOPE EFFECTS ON THE SPONTANEOUS AND ANTIBODY-CATALYZED DECARBOXYLATION OF 5-NITRO-3-CARBOXYBENZISOXAZOLE

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.

Aspects of the aromaticity of anthranil

The standard (pdegrees = 0.1 MPa) molar enthalpy of formation of liquid anthranil was measured at T = 298.15 K by static bomb calorimetry and the standard molar enthalpy of vaporization at T = 298.15 K was obtained using Calvet microcalorimetry. These values were used to derive the standard molar enthalpy of formation of anthranil in the gaseous phase. Thermochemical and quantum chemical comparisons were made to interrelate anthranil and its isomers, 1,2-benzisoxazole, benzoxazole and 2-cyanophenol, and the monocyclic heterocycles, isoxazole and oxazole. Comparisons with benzofurazan and isobenzofuran were also made. Additionally nucleus-independent chemical shifts were used as an aromaticity index. (C) Wiley-VCH Verlag GmbH & Co.

CATALYSIS OF DECARBOXYLATION OF 6-NITROBENZISOXAZOLE-3-CARBOXYLATE BY CATIONIC POLYMER COLLOIDS

Polystyrene latexes with quaternary ammonium ion-exchange sites catalyze the decarboxylation of 6-nitrobenzisoxazole-3-carboxylate in aqueous dispersions. A catalytic rate constant of 2.1 X 10(4) times the rate constant in water was achieved in particles containing 24 mol % of poly((styrylmethyl)tri-n-butylammonium chloride) repeat units. This is the largest rate enhancement reported at 25 degrees-C for decarboxylation of 6-nitrobenzisoxazole-3-carboxylate in any colloidal or polymeric medium. The decarboxylation kinetics fit both the enzyme model of micellar catalysis and an ion-exchange model. Added electrolyte decreases the rate of decarboxylation but increases the intrinsic catalytic rate constants in the more highly swollen latexes. The fraction of (styrylmethyl)trimethylammonium ion repeat units in the polymers has little effect on the rate of decarboxylation. The catalytic activity of the poly((styrylmethyl)trailkylammonium) ions in the latex increases in the order of in lipophilicity: Me < Et < Pr < Bu. The 200-350-nm diameter monodisperse colloidal particles with varied functional group content were prepared by emulsion copolymerization of styrene, (styrylmethyl)trimethylammonium chloride, divinylbenzene, and (chloromethyl)styrene followed by reactions with trialkylamines to form the anion-exchange sites.
