One aspect of the disclosure relates to the use of derivatives of dichlorophenyl urea for treating cancers.

Compound for treating cancer and diabetes

Partial depletion of RLIP76 in p53 deficient living subject has shown many health benefits. In one embodiment, partical Rlip depletion is used to prevent or treat cancer in p53 deficient living subjects. In another embodiment, partial Rlip depletion is used for reversion of DNA-methylation abnormalities caused by the lack of p53 to normal in p53 deficient living subjects. In yet another embodiment, partial Rlip depletion is used in reduction of blood glucose, insulin-resistance, hyperlipidemina, or any combination thereof in p53 deficient living subjects. Methods of using liposome containing anti-sense nucleic acid or double stranded siRNA to partially deplete RLIP76 and thus treat p53 deficient subject are disclosed. The approaches described herein can be especially helpful in preventing cancer in Li-Fraumeni patients.

Cancer treatment through RLIP76 partial depletion

The present disclosure provides novel methods for increasing &#x3b2;-cell viability in islets by delivering RLIP76 polypeptides or GSTA4 polypeptides, or a combination thereof; or RLIP76 polynucleotides or GSTA4 polynucleotides, or a combination thereof, to the islets. The disclosure also provides novel methods for treating a disease or condition in a subject, such as type 1 diabetes mellitus, by delivering RLIP76 polypeptides or GSTA4 polypeptides, or a combination thereof; or RLIP76 polynucleotides or GSTA4 polynucleotides, or a combination thereof, to islets and transplanting the islets into the subject to treat the disease or condition. Kits and compositions including RLIP76 polypeptides or GSTA4 polypeptides, or a combination thereof; or RLIP76 polynucleotides or GSTA4 polynucleotides, or a combination thereof, are also provided to increase &#x3b2;-cell viability.

Methods, compositions, and kits for improving pancreatic beta cell viability and treating diseases or conditions related to beta cell destruction

One aspect of the disclosure relates to derivatives of aryl and heterocyclic ureido aryl and heterocyclic carboxamido isobutyric acids, dichlorophenyl urea, curcumin, and 1,3-diazetidine-2,4-dione, and pharmaceutical compositions thereof. The derivatives disclosed herein can modulate development of adipocytes and various cancer cells, including resistant cancer cells and cancer stem cells. Another aspect of the disclosure relates to the use of the derivatives and pharmaceutical compositions disclosed herein in treatment of obesity and various cancers.

Modulators of development of adipocyte and cancer cells

Methods of preparing a proteoliposorne comprise the step of contacting a liposome with an effective portion of RalBP1 to create a proteoliposorne. RalBP1 is effective for the protection and treatment of mammals and the environment against the accumulation of toxic compounds, and prevents accumulation of one or more toxic compounds, reduces the concentration of toxic compounds, and protects against further contamination with one or more toxic compounds. In addition, RalBP1 is effective for the protection and treatment of mammals against the effects of ionizing radiation.

Protection against and treatment of ionizing radiation

The present invention is a composition identified as a region of ralA binding protein 1, wherein the region neighbors a membrane-associated portion of the ralA binding protein 1, reduces transport activity and membrane association of the ralA binding protein 1 and kills cells undergoing uncontrolled cell growth in a subject that has cells undergoing uncontrolled cell growth. The region is used to generate medicines that kill malignant cells and tumorigenic cells. Medicines may be in the form of antibodies, si-RNA and small molecules that recognize the region.

Therapies for cancer using RLIP76

Methods of preparing a proteoliposome comprise the step of contacting a liposome with an effective portion of RalBP1 to create a proteoliposome. RalBP1 is effective for the protection and treatment of mammals and the environment against the accumulation of toxic compounds and prevents accumulation of one or more toxic compounds, reduces the concentration of toxic compounds, and protects against further contamination with one or more toxic compounds.

RLIP76 liposomes for protection against irradiation

Compositions and methods for modifying one or more biologic targets are provided. Suitable targets include cells, DNA, proteins, enzymes, and/or a subject in need thereof. The compositions may exist as a monomer or multimer and are active in a biologic environment with enhanced activity in hypoxic environments and, thus, exhibit improved specificity for hypoxic biologic targets (e.g., tumorigenic cells and those undergoing uncontrolled cell growth). A composition typically comprises a complex with an overall charge of 2+ or greater having at least one ruthenium atom attached to a redox active ligand. The redox active ligand helps maintain separation of more than one ruthenium atom. Suitable compositions may further include a terminal ligand comprising a heterocyclic aromatic compound. When provided to a biologic target, the composition modifies the biologic target and no additional compounds need be provided. Suitable compositions are typically catalytic and regenerative in the presence of a reducing agent.

Compounds with modifying activity enhanced under hypoxic conditions

Methods of preparing a proteoliposome comprise the step of contacting a liposome with an effective portion of RalBP1 to create a proteoliposome. RalBP1 is effective for the protection and treatment of mammals and the environment against the accumulation of toxic compounds, and prevents accumulation of one or more toxic compounds, reduces the concentration of toxic compounds, and protects against further contamination with one or more toxic compounds. In addition, RalBP1 is effective for the protection and treatment of mammals against the effects of ionizing radiation.
