Patents by Inventor Andreas G. Schatzlein

Andreas G. Schatzlein has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8470371
    Abstract: Polymeric micellar clusters formed from amphiphilic carbohydrate polymers and their uses in formulating drugs is disclosed, and in particular the finding that amphiphilic carbohydrate polymers are capable of self assembling to form micellar clusters in which the carbohydrate amphiphiles aggregate into hierarchically organized micellar clusters of individual aggregates. The micellar clusters may be transformed into stable nanoparticles with drugs, especially hydrophobic drugs that have poor aqueous solubility, and may improve the transfer of hydrophobic drugs across biological barriers.
    Type: Grant
    Filed: August 8, 2007
    Date of Patent: June 25, 2013
    Assignee: University College London

  • Publication number: 20080267903
    Abstract: Various polymers, including cationic polyamine polymers and dendrimeric polymers, are shown to possess anti-proliferative activity, and may therefore be useful for treatment of disorders characterised by undesirable cellular proliferation such as neoplasms and tumours, inflammatory disorders (including autoimmune disorders), psoriasis and atherosclerosis. The polymers may be used alone as active agents, or as delivery vehicles for other therapeutic agents, such as drug molecules or nucleic acids for gene therapy. In such cases, the polymers' own intrinsic anti-tumour activity may complement the activity of the agent to be delivered.
