  • Synthesis of oligo/poly(catechins) and methods of use
    Patent number: 8143308
    Abstract: A method for synthesizing a biocompatible, water-soluble oligo/polyflavanoid, includes polymerizing an optionally substituted flavanoid with a polymerization agent in the presence of a biocompatible polymerization solubilizer, thereby producing the biocompatible, soluble oligo/polyflavanoid. Also included is a biocompatible, soluble, oligo/polyflavanoid or a pharmaceutically acceptable salt, solvate, or complex thereof. Also included are methods of treating a subject for cancer, cardiac damage, viral infection, and obesity.
