  • Patent number: 8623854
    Abstract: A method of treating cancer in a subject comprising the step of administering to the subject in need thereof an effective amount of a combination of a compound that binds a nuclear export signal (NES inhibitor) on topoisomerase II? and a topoisomerase inhibitor. Twenty small molecule inhibitors (SMI) that bind to the two nuclear export sequences (NES) topo II? have been identified from the NCI database using computer-generated molecular modeling. These SMI will improve the effectiveness of topo II directed therapeutics, particularly in the treatment of diseases such as multiple myeloma (MM). In vitro apoptosis assays indicate that these drugs may be effective as single agents or in combination with currently used cancer drugs that target topo II.

  • Publication number: 20130281389
    Abstract: Topoisomerase II alpha (topo II?) is exported from the cell nucleus in human myeloma cells by a chromosome-maintenance protein-1 (CRM1)-dependent mechanism, resulting in topo II inhibitor resistance. The nuclear export signal (NES) of topo II? is unique, making it a potential target for small molecule inhibitors. Small molecules NES inhibitors were identified, which inhibited binding of topo II? to the export receptor CRM1. Inhibition was specific to topo II? as p53 trafficking was unaffected along with topo II? protein expression and function (decatenation). These topo II?-specific nuclear export inhibitors may potentially lead to a new approach in circumventing drug resistance in multiple myeloma. The compounds provide a protocol for treating multiple myeloma or an oncogenic disease. Further, the topoisomerase II nuclear export signal inhibitor may be combined with a topoisomerase II inhibitor.

  • Patent number: 8545841
    Abstract: The subject application provides small compounds that are able to suppress autophagy in various cells. These compounds are useful in augmenting the existing treatments of various cancers and microbial/parasitic infections. Thus, the subject application also provides methods of treating various types of cancers and microbial/parasitic infections. Also provided by the subject application are methods of suppressing the expansion of autophagosomes within cells or individuals and inhibiting the lipidation of autophagy-related protein 8 (Atg8).

  • Publication number: 20130189257
    Abstract: The subject invention pertains to uses of PKC-iota inhibitors for treatment of breast cancer. In one embodiment, the subject invention provides novel uses of 1H-imidazole-4-carboxamide, 5-amino-1-[2,3 -dihydroxy-4-[(phosphonooxy) methyl]cyclopentyl]-,[1R-(1?, 2?, 3?, 4?)] (ICA-1) and related compounds for treatment of breast cancer. The compounds of the subject invention have potent anti-proliferative effects against human breast cancer cells. The compounds of the subject invention also inhibit the phosphorylation of IKK-?/IKK-?, induce chromatin condensation, and/or induce DNA fragmentation in cancer cells.
