  • Publication number: 20140037731
    Abstract: A method for preparing hydro/organo gelators from disaccharide sugars by biocatalysis and their use in enzyme-triggered drug delivery. Controlled delivery of an anti-inflammatory, chemopreventive drug is achieved by an enzyme-triggered drug release mechanism via degradation of encapsulated hydrogels. The hydro- and organo-gelators are synthesized in high yields from renewable resources by using a regioselective enzyme catalysis and a known chemopreventive and anti-inflammatory drug, curcumin, is encapsulated in the gel matrix and released by enzyme triggered delivery. The release of the drug occurs at the physiological temperature and control of the drug release rate is achieved by manipulating the enzyme concentration and temperature. The by-products formed after the gel degradation clearly demonstrated the site specificity of degradation of the gelator by enzyme catalysis.
