专利号:US-11434195-B2 优先权日:2017-07-20 标题:Compositions and methods for treatment of central nervous system tumors 发明人:SVETLOV STANISLAV IGOREVICH 权利人:UNIV FLORIDA 摘要:Compounds, pharmaceutical compositions, and methods for treating cancer, in particular brain cancer, are provided, including amphiphilic fatty acid/alcohol ethers (AIPs) comprising endocannabinoid and FABP motifs covalently linked to a beta-adrenoreceptor antagonist motif in one molecule. The invention includes methods for inhibiting growth of brain cancer cells by contacting the compound(s) with brain cancer cells. The invention provides a method for treating both brain cancer and brain cancer metastases, and for suppression of regrowth of brain cancer cells after radiation, surgical treatment, or chemotherapy of brain cancer. The invention also comprises an optimized chemical synthesis of the AIP compounds and methods of using the compounds, alone or in combination with another agent, for suppressing the growth of brain cancer cells, and enhancing survival of normal CNS cells, or improving recuperation from radiation, surgical or chemotherapy.
专利号:US-2005080260-A1 优先权日:2003-04-22 标 题 :Preparation of prodrugs for selective drug delivery 发明人:MILLS RANDELL L; WU GUO-ZHANG 摘要:Synthesis of a chemical compound having the formula A-B-C that may serve for applications such as drug delivery where A is a chemiluminescent, moiety, B is a photochromic moiety, and C is a biologically active moiety where A-B-C may serve as a prodrug. Novel synthetic methods of the present invention to form the prodrug comprised the steps of (1) forming a benzophenone, (2) forming a diaryl ethylene, (3) attaching a phthalimide moiety to at least one of the aryl groups of the ethylene to form a phthalimide-ethylene conjugate, (4) condensing two ethylene-phthalimide conjugates to form a phthalimide-pentadiene conjugate, (5) converting the phthalimide to the phthalhydrazide by reaction with hydrazine to form a carrier compound according to the present invention, and (6) reacting the carrier compound with an nucleophilic moiety of the drug to form the corresponding prodrug. Alternatively the carrier can be prepared by using the halo-substituted diaryl ethylene to make the corresponding cationic leuco dye-like compound with known methods. The cationic compound then is protected by reacting with a nucleophile and coupled with the aminophathalimide by palladium-catalyzed amination to form the protected phthalimide-pentadiene conjugate. The latter is refluxed with hydrazine to convert its phthalimide to the phthalhydrazide and acidified to give the carrier. An additional aspect of the present invention relates to the use of these compounds as antiviral agents for the treatment of viral infections such as HIV and as anticancer agents for the treatment of cancers such as bowel, lung, and breast cancer.

The inventors have observed that cancers exhibiting recruitment of MDM2 to chromatin have been shown to secrete IL-6 that in turn acts on myoblast cells to activate serine synthesis. Following these surprising and unexpected observations. the inventors set up methods of treatment that are able to induce cancer cells death in subjects that have been previously classified as being affected with a cancer exhibiting recruitment of MDM2 to chromatin.
