ACTIVE AGENTS AND METHODS OF THEIR USE FOR THE TREATMENT OF METABOLIC DISORDERS AND NONALCOHOLIC FATTY LIVER DISEASE

Disclosed herein are active agents, compositions containing them, unit dosage forms containing them, and methods of their use, e.g., for treating a metabolic disorder or nonalcoholic fatty liver disease or for modulating a metabolic marker or nonalcoholic fatty liver disease marker.

Nucleophilic Substitution Reactions of Pyranose Polytosylates

The 2,3,4-tri-toluenesulfonate ester derivatives of the methyl pyranosides of L-arabinose, D-ribose, D-lyxose, and D-xylose have been prepared, and their substitution reactions with various nucleophiles have been examined. For arabinose, xylose, and ribose, highly regioselective monosubstitutions were observed with benzoate, nitrite, and azide anions. These reactions have led to short and simple routes from D-xylose to L-arabinose derivatives, from L-arabinose to D-xylose derivatives, and from D-ribose to L-lyxose derivatives. The tritosylate derived from methyl α-D-lyxopyranoside was unreactive toward nucleophilic substitution reactions, giving instead a dihydropyran product arising from an initial E2 elimination reaction of the 2-tosylate.

Synthesis of C7-C16-alkyl glycosides: Part II - Synthesis of alkyl d-xylopyranosides in the presence of tin(IV) chloride as a Lewis acid catalyst

The Lewis acid catalyzed glycosylation reaction of β-peracetylated sugar derivatives (xylose) with fatty alkanols is used in a synthesis of C7-C16-alkyl D-xylopyranosides. The process occurs under the influence of tin(IV) chloride.

Porcine liver esterase-catalyzed hydrolysis of methyl tri-O-acetyl-β-D-arabinopyranoside, methyl tri-O-acetyl-β-D-ribopyranoside and methyl tri-O-acetyl-β-D-ribofuranoside

Methyl 2,3,4-tri-O-acetyl-β-D-arabinopyranoside (1), methyl 2,3,4-tri-O-acetyl-β-D-ribopyranoside (2), and methyl 2,3,5-tri-O-acetyl-β-D-ribofuranoside (3) were deacetylated in porcine liver esterase-catalyzed reactions. Triacetate 1 gave methyl 3,4-di-O-

Synthesis of acylated methyl β-D-xylopyranosides and their enzymic deacylations by rabbit serum esterases

Selective pivaloylations of methyl β-D-xylopyranoside have been studied under various reaction conditions. Partially pivaloylated products were submitted to additional acetylations. The structures were established by 1H NMR spectroscopy. Representatives of acylated methyl β-D-xylopyranosides (acyl being pivaloyl, acetyl, or a combination of both) were submitted to hydrolysis catalyzed by rabbit serum and esterases isolated from rabbit serum.

Oviposition Deterrent of a Rutaceae-feeding Swallowtail Butterfly, Papilio xuthus, from a Non-host Rutaceous Plant, Orixa japonica

Females of the Rutaceae-feeding swallowtail butterfly, Papilio xuthus, do not oviposit on the rutaceous plant, Orixa japonica.A methanolic extract of O. japonica leaves was found to contain contact-chemical factors which deterred oviposition of the butter
