New securinine analogues have been prepared by semisynthesis. Two series were developed using either Suzuki or Sonogashira cross coupling reactions. The in vitro cytotoxicity of the compounds was assayed against HCT-116 colon cancer cells. The most potent derivatives showed promising growth inhibition on four tumoral cell lines giving a valuable insight on the structure–activity relationship (SAR)
surprising rearrangement was observed during the reaction of securinine with tribromo-isocyanuric acid or 1,3-dibromo-5,5-dimethylhydantoin in methanol, yielding a stereoselective ringcontraction norsecurinine derivative. Meanwhile two oxidation rearrangement products were also reported. Some preliminary discussions on the reactivity of securinine were conducted from these rearrangements; it is believed

The present application relates to securinine or norsecurinine analogues that, when administered to immature myeloid cells, promote differentiation of these cells to mature cells that do not readily proliferate. Therefore, the agents are useful in the treatment of myeloid disorders including myeloproliferative disorders, acute myeloid leukemia, and autoimmune diseases. The agents may also be used as a myeloablative agent in conjunction with a bone marrow transplant or stem cell therapy.

The present invention relates to novel securinine and norsecurine analogs that have reduced or non-reduced gamma-delta bond. The present invention also provides for methods of using securinine analogs, comprising administering one or more of the analogs to a myeloperoxidase enzyme, such as an enzyme with or proximal to a cell. As set out herein, the securinine analogs directly bind to and inhibit myeloperoxidase (MPO) activity. Accordingly, contacting or administering the analogs to an MPO enzyme allows for inhibition of MPO activity.
