PLANT OR MICROORGANISM-DERIVED CAROTENOID-OXYGEN COPOLYMER COMPOSITIONS, METHODS OF IDENTIFYING, QUANTIFYING AND PRODUCING SAME AND USES THEREOF

The present invention relates to carotenoid-oxygen copolymers, compositions, methods of identifying and quantifying carotenoid-oxygen copolymers in food and related sources, and methods of producing compositions comprising same. In one aspect the method of identifying and quantifying carotenoid-oxygen copolymers comprises an analysis of a low molecular weight marker compound in said sources. In another aspect the present invention provides a method of preparing compositions comprising said carotenoid-oxygen copolymers and/or enhancing levels of said copolymers in food sources in a sufficient and practically useful concentration to have beneficial effects in animals and humans, including beneficial immunological and health effects.

Oxidation of α-Substituted Cyclohexanols by Nitric Acid

The influence of α-substituents on the oxidative cleavage of cyclohexanol by nitric acid in the presence of copper(II) and vanadium(V) ions has been investigated.Following the initial oxidation to give the cyclohexanone, further reaction, leading to ring opening of the ketone, requires at least one α-hydrogen.Thus 2,2,6,6-tetramethylcyclohexanol is converted to the corresponding ketone whilst 2,2,6-trimethylcyclohexanol is oxidised to a mixture of dicarboxylic acids.The mechanisms of the oxidations are discussed and enolisation is shown to be the key to oxidative cleavage.For ketones that can give two alternative enols, reaction occurs predominantly via the more stable tautomer.

1,1-Alkanediol dicarboxylate linked antibacterial agents

Useful antibacterial agents in which a penicillin and/or a beta-lactamase inhibitor are linked via 1,1-alkanediol dicarboxylates are of the formula STR1 where A is the residue of certain dicarboxyic acids, R3 is H or (C1 -C3), n is zero or 1 such that when n is zero R is P or B and R1 is the residue of certain esters, H or a salt thereof; and when n is 1, one of R and R1 is P and the other is B, and P is STR2 where R2 is H or certain acyl groups, and B is the residue of a beta-lactamase inhibiting carboxylic acid; a method for their use, pharmaceutical compositions thereof and intermediates useful in their production.
