  Synthesis and photochemical behavior of coumarin-caged cholesterol

  摘要：

  The syntheses of three coumarin-caged cholesterols are reported that contain the 6-diethylaminocoumarin (DEACM), 6-bromo-7-hydroxycoumarin (BHC) and 6-bromo-7-methoxycoumarin (BMCM) photocleavable groups. Upon photolysis, the best caged derivative was found to be BHC-cholesterol whose quantum yield was determined to be 0.032 at 350 nm. (C) 2013 Elsevier Ltd. All rights reserved.

  The invention comprises compounds, methods of making, and methods of using. The compounds may have a linear or cylic backbone and three or four appended functional groups: one or two lipohilic compounds including sterols or “fat soluble” vitamins, one or two hydrophilic polymer, and one or two carbohydrate. A group of polymer-carbohydrate conjugates having a central backbone and three appended functional groups are disclosed wherein one lipophilic compound is void of both steroid acids. The conjugate may have fatty acids as the primary lipophilic carrier, one hydrophilic polymer, and one carbohydrate. Specific functional groups may be selected for specific applications in formulating pharmaceuticals, cosmetics, nutriceuticals, and the like. Typical coupling reaction of the conjugates may involve one or more or combinations or in series of alkylation including N-alkylation or O-alkylation, etherification, esterification and amidation chemical processes. A variety of linkers between the backbone and functional groups may also be selected to modify the carriers or center backbones for the coupling reactions and optimize performance of the conjugates.

  Antimicrobial cationic polymers having one or two cationic polycarbonate chains were prepared by organocatalyzed ring opening polymerization. One antimicrobial cationic polymer has a polymer chain consisting essentially of cationic carbonate repeat units linked to one or two end groups. The end groups can comprise a covalently bound form of biologically active compound such as cholesterol. Other antimicrobial cationic polymers have a random copolycarbonate chain comprising a minor mole fraction of hydrophobic repeat units bearing a covalently bound form of a vitamin E and/or vitamin D2. The cationic polymers exhibit high activity and selectivity against Gram-negative and Gram-positive microbes and fungi.
