    摘要: Certain embodiments of the invention provide antioxidant-based diacids and polymers comprising glycol groups as described herein, and methods of use thereof. In certain embodiments the polymers described herein are formulated as microspheres or hydrogels. Described herein is the chemical incorporation of antioxidants, e.g., coumaric acid, ferulic acid, and sinapic acid, into a polymer backbone for use, e.g., in applications for localized release and rapid delivery. As provided, the chemical composition of the linker molecules used (of which hold together two bioactives via ester linkages) may be used to vary the hydrophilicity of the polymer. The bioactive release rate may also be altered for a tunable release delivery system, allowing for increased bioactive release compared to other linkers previously utilized.

    摘要: Present invention relates to an improved and commercial process for the preparation of 2-sustituted-2-(6-(substituted)-7-methylbenzo[d][1,3]dioxol-4-yl)acetic acid derivatives of formula-I [Formula should be inserted here], wherein R 1 is a O-protecting group such as methoxymethyl, ethoxymethyl, trialkylsilyl, arylmethyl, tetrahydropyran-2-yl, allyl; X is hydroxyl, halogen, mesylate, triflate, tosylate, acetate; Y is oxygen atom, NH or sulfur atom; R 2 is C 1 -C 6 alkyl. 2,4-Dihydroxy-3-methylbenzaldehyde is selectively protected at C-4 position in the form of an ether compound of formula-XII, oxidized the aldehyde function to get the diol of formula-XIII, and condensed with ethyl glyoxalate under Casiraghi reaction conditions to get the compound of formula-XV. Compound of formula-XV is converted to compound of formula-I by conventional chemistry. Compounds of formula-I are key intermediates in the synthesis of ecteinascidines like trabectedin
