  • Patent number: 8993620
    Abstract: Cinnamic acid-based oligomers and therapeutic uses thereof are provided. The oligomers are used as anti-inflammation agents, inhibitors of elastase and anti-oxidants, and in some cases (e.g. the treatment of lung disorders such as lung cancer) all three activities are simultaneously beneficial. Subsets of the oligomers (e.g. ?-O4 and ?-5 trimers and tetramers) are used as anticoagulants.
