  • Patent number: 10751344
    Abstract: Carbon monoxide-releasing organic molecules are described herein. The molecules can be synthesized prior to administration (e.g., ex vivo) or formed in vivo. In those embodiments where the molecules are formed in vivo, reactants are administered under physiological conditions and undergo a cycloaddition reaction to form a product which releases carbon monoxide. In applying such reactions for therapeutic applications in vivo, the cycloaddition and CO release typically occur only under near-physiological or physiological conditions. For example, in some embodiments, the cycloaddition reaction and/or release of carbon monoxide occur at a temperature of about 37° C. and pH of about 7.4. Pharmaceutical compositions and methods for release carbon monoxide are also described.

  • Patent number: 10544090
    Abstract: Rhein analogues that exhibit anti-proliferative activity, particular against cancer cells, are described herein. In some embodiments, the compounds contain a flat or planar ring system. Such rings system by facilitate non-covalent binding of the compounds to the DNA complex, such as by intercalation. In some embodiment, the compounds contain a flat or planar ring system as described above and one or more substituents which are alkylating moieties, electrophilic groups or Michael acceptors or groups which contain one or more alkylating moieties, electrophilic groups and/or Michael acceptors. The compounds described herein can also contain one more functional groups to improve the solubility of the compounds.
