  • Patent number: 7858105
    Abstract: Methods and formulations are provided to reduce pigmentation in skin, using an array of compounds selected from benzimidazoles, phenylthioureas, phenylthiols, phenylamines, bi- and multicyclic phenols, thiopheneamines, and benzothiamides. The compounds preferably inhibit pigment synthesis in melanocytes through the tyrosinase pathway. The methods can be used for lightening skin, and for treating uneven skin complexions which result from hyperpigmentation-related medical conditions such as melasma, age spots, freckles, ochronosis, and lentigo. The compounds can be used medically or cosmetically.

  • Patent number: 7208528
    Abstract: Novel inhibitors of polyamine transport having inhibition constants two orders of magnitude lower than those of known compounds are disclosed. These polyamine analogues are useful pharmaceutical agents for treating diseases where it is desired to inhibit polyamine transport or other polyamine binding proteins, for example cancer and post-angioplasty injury. Novel chemical synthetic methods to obtain polyamine analogues are disclosed, including the production of a combinational polyamine library. These approaches yield analogues with desirable activities both for diagnostic and research assays and therapy. The assays of the invention are useful for high throughput screening of targets in the discovery of drugs that interact with the polyamine system.

  • Patent number: 7144920
    Abstract: Novel polyamines, their synthesis and use in pharmacological, cosmetic or agricultural applications are provided. The polyamines induce antizyme production which in turn down regulates both the production of polyamines by omithine decarboxylase (ODC) and the transport of polyamines by its corresponding polyamine transporter. These compounds will preferably enter the cell independent of the polyamine transporter. As drugs, these compounds are used to treat any disease associated with cellular proliferation including but not limited to cancer.
