  • Patent number: 7741474
    Abstract: This invention relates to novel carbohydrate polymers with hydrophobic and hydrophilic side-groups suitable for solubilising, for example, hydrophobic drugs. The chain length of the carbohydrate polymeric backbone, and the type and number of the hydrophobic and hydrophilic side-groups are specifically chosen to improve the solubility properties of the carbohydrate polymers.

  • 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.
