[0006] Cancer is a multifactorial disease characterized by uncontrolled cell proliferation, tumor formation, growth, and, in some cases, metastasis. Cells harboring activated oncogenes, damaged genomes, or other cancer-promoting alterations are prevented from replicating by an elaborate tumor suppressor network. A central component of this tumor suppressor network is p53, one of the most potent tumor suppressors in cells. Both wild-type and mutant forms of p53 are implicated in the progression of cancer.

[0069] Figure 2 Protein DNA binding assay of mutant p53 in the presence of the compounds of the present invention is shown to demonstrate the specificity of the compounds of the present invention. DETAILED DESCRIPTION
[0070] The present invention provides compounds and methods for restoring wild-type function to mutant p53. The compounds of the present invention can bind to mutant p53 and restore the mutant p53's ability to bind DNA. Restoration of mutant p53 activity can allow activation of p53's downstream effectors, leading to inhibition of cancer progression. The present invention also provides methods for treating cancerous lesions or tumors harboring p53 mutations.
[0071] Cancer is a collection of related diseases characterized by uncontrolled cell proliferation with the ability to metastasize throughout the body. Cancer can be divided into five major categories, including, for example: carcinomas, which can arise from cells that line the inside and outside of the body, such as the lungs, breast, and colon; sarcomas, which can arise from cells located in bone, cartilage, fat, connective tissue, muscle, and other supporting tissues; lymphomas, which can arise in the lymph nodes and immune system tissue; leukemias, which can arise in the bone marrow and accumulate in the bloodstream; and adenomas, which can arise in the thyroid, pituitary, adrenal, and other glandular tissues.
[0072] While different cancers can develop in nearly any tissue of the body and contain unique characteristics, the basic processes that lead to cancer are likely similar across all forms of the disease. Cancer begins when cells break free from their normal constraints on cell division and begin to grow and divide uncontrollably. Genetic mutations in cells can eliminate the cell's ability to repair damaged DNA or initiate apoptosis, leading to uncontrolled cell growth and division.
[0073] The ability of a tumor cell population to expand depends not only on the rate of cell proliferation but also on the rate of cell attrition. Programmed cell death, or apoptosis, represents the primary mechanism of cell attrition. Cancer cells can evade apoptosis through various strategies, such as inhibiting p53 function and thereby suppressing the expression of pro-apoptotic proteins.
[0074] Oncogenes and tumor suppressor genes can regulate cell proliferation. Genetic mutations can affect oncogenes and tumor suppressor genes, potentially activating or inhibiting their activity abnormally, further promoting uncontrolled cell division. Oncogenes contribute to cell growth, while tumor suppressor genes slow cell division by repairing damaged DNA and activating apoptosis. Cellular oncogenes that may mutate in cancer include, for example, Cdk1, Cdk2, Cdk3, Cdk4, Cdk6, EGFR, PDGFR, VEGF, HER2, Raf kinase, K-Ras, and myc. Tumor suppressor genes that may mutate in cancer include, for example, BRCA1, BRCA2, cyclin-dependent kinase inhibitor 1C, retinoblastoma protein (pRb), PTEN, p16, p27, p53, and p73.
[0075] Tumor suppressor p53
[0076] The tumor suppressor protein p53 is a 393 amino acid transcription factor that can regulate cell growth in response to cellular stresses including, for example, UV radiation, hypoxia, oncogene activation, and DNA damage. p53 has multiple mechanisms that inhibit cancer progression, including, for example, initiation of apoptosis, maintenance of genomic stability, cell cycle arrest, induction of senescence, and inhibition of angiogenesis. Due to its critical role in tumor suppression, p53 is inactivated in almost all cancers, either through direct mutation or through interference with related signaling pathways involved in tumor suppression. Homozygous deletion of the p53 gene occurs in almost all types of cancer, including breast cancer, colon cancer, and lung cancer. The presence of certain p53 mutations in several types of human cancer may be associated with a less favorable patient prognosis.
[0077] In the absence of stress signals, p53 levels are maintained low by its interaction with the E3 ubiquitin ligase Mdm2. In unstressed cells, Mdm2 targets p53 for degradation by the proteasome. Under stressful conditions, the interaction between Mdm2 and p53 is disrupted, leading to p53 accumulation. A key event leading to p53 activation is phosphorylation of the N-terminal domain of p53 by protein kinases, which transduce upstream stress signals. Phosphorylation of p53 induces conformational changes that promote p53 DNA binding and allow transcription of downstream effectors. Activation of p53 can induce, for example, intrinsic and extrinsic apoptotic pathways, cell cycle arrest, senescence, and DNA repair. p53 can activate proteins involved in the above-mentioned pathways, including, for example, Fas / Apo1, KILLER / DR5, Bax, Puma, Noxa, Bid, caspase-3, caspase-6, caspase-7, caspase-8, caspase-9, and p21 (WAF1). In addition, p53 can inhibit the transcription of multiple genes including, for example, c-MYC, cyclin B, VEGF, RAD51, and hTERT.
[0078] Each chain of the p53 tetramer is composed of several functional domains, including the transactivation domain (amino acids 1-100), the DNA binding domain (amino acids 101-306), and the tetramerization domain (amino acids 307-355), which are highly mobile and largely unstructured. Most p53 cancer mutations are located in the protein's DNA-binding core domain, which contains a central β-sandwich structure of antiparallel β-sheets that serves as the basic scaffold for the DNA binding surface. The DNA binding surface consists of two β-turn loops, L2 and L3, stabilized by zinc ions, such as at Arg175 and Arg248, and a loop-sheet-helix motif. Together, these structural elements form an extended DNA-binding surface that is rich in positively charged amino acids and specifically contacts various p53 response elements.
[0079] Since p53 mutations are prevalent in almost all types of cancer, the reactivation of wild-type p53 function in cancer cells may be an effective therapy. P53 mutations located in the DNA binding domain of the protein or the periphery of the DNA binding surface lead to abnormal protein folding required for DNA recognition and binding. Mutations in p53 can occur at, for example, amino acids Val143, His168, Arg175, Tyr220, Gly245, Arg248, Arg249, Phe270, Arg273, and Arg282. P53 mutations that can eliminate p53 activity include, for example, R175H, Y220C, G245S, R248Q, R248W, R273H, and R282H. These p53 mutations can distort the structure of the DNA binding site or thermodynamically destabilize the folded protein at body temperature. Wild-type function of p53 mutants can be restored by binding them to compounds that shift the folding-unfolding equilibrium toward the folded state, thereby reducing the rate of unfolding and destabilization.
[0080] Non-limiting examples of amino acids include: alanine (A, Ala); arginine (R, Arg); asparagine (N, Asn); aspartic acid (D, Asp); cysteine (C, Cys); glutamate (E, Glu); glutamine (Q, Gln); glycine (G, Gly); histidine (H, His); isoleucine (I, He); leucine (L, Leu); lysine (K, Lys); methionine (M, Met); phenylalanine (F, Phe); proline (P, Pro); serine (S, Ser); threonine (T, Thr); tryptophan (W, Trp); tyrosine (Y, Tyr); and valine (V, Val).
[0081] Mechanism of the compounds of the present invention
[0082] The compounds of the present invention can selectively bind to p53 mutants and restore wild-type activity of p53 mutants, including, for example, DNA binding function and activation of downstream targets involved in tumor suppression. In some embodiments, the compounds of the present invention selectively bind to the p53 Y220C mutant. The Y220C mutant is a temperature-sensitive mutant that binds to DNA at lower temperatures and denatures at body temperature. The compounds of the present invention can stabilize the Y220C mutant to reduce the likelihood of protein denaturation at body temperature.
[0083] The aromatic ring of Y220 is located at the periphery of the p53 β-sandwich structure connecting β-strands S7 and S8 and is an integral part of the hydrophobic core of the β-sandwich. The Y220C mutation is highly destabilizing due to the formation of an internal surface cavity. The compounds of the present invention can bind to and occupy this surface cleft, stabilizing the β-sandwich structure and thereby restoring wild-type p53 DNA binding activity.
[0084] To determine the ability of the compounds of the invention to bind to and stabilize mutant p53, assays can be used to detect, for example, conformational changes in p53 mutants or activation of wild-type p53 targets. Conformational changes in p53 can be measured, for example, by differential scanning fluorimetry (DSF), isothermal titration calorimetry (ITC), nuclear magnetic resonance spectroscopy (NMR), or X-ray crystallography. In addition, antibodies specific for wild-type mutant conformations of p53 can be used to detect conformational changes by, for example, immunoprecipitation (IP), immunofluorescence (IF), or immunoblotting.
[0085] Methods used to detect the ability of p53 mutants to bind DNA can include, for example, DNA affinity immunoblotting, modified enzyme-linked immunosorbent assay (ELISA), electrophoretic mobility shift assay (EMSA), fluorescence resonance energy transfer (FRET), homogeneous time-resolved fluorescence (HTRF), and chromatin immunoprecipitation (ChIP) assays.
[0086] In order to determine whether the compounds described herein can reactivate the transcriptional activity of p53, the activation of downstream targets in the p53 signaling cascade can be measured. The activation of p53 effector proteins can be detected by, for example, immunohistochemistry (IHC-P), reverse transcription polymerase chain reaction (RT-PCR) and Western blotting. The activation of p53 can also be measured by inducing apoptosis via the caspase cascade and using methods including, for example, annexin V staining, TUNEL assays, procaspase and caspase levels and cytochrome c levels. Another consequence of p53 activation is aging, which can be measured using methods such as beta-galactosidase staining.
[0087] The p53 mutants that can be used to determine the effectiveness of the compounds of the present invention in enhancing the DNA binding ability of p53 mutants are p53 truncation mutants that contain only amino acids 94-312, comprising the DNA binding domain of p53. For example, the sequence of the p53Y220C mutant used to test the efficacy of the compounds can be:

[0209] Compounds can be delivered via liposome technology. Using liposomes as drug carriers can increase the therapeutic index of a compound. Liposomes are composed of natural phospholipids and may contain mixed lipid chains with surfactant properties (e.g., egg phosphatidylethanolamine). Liposome design can employ surface ligands to attach to unhealthy tissues. Non-limiting examples of liposomes include multilamellar vesicles (MLVs), small unilamellar vesicles (SUVs), and large unilamellar vesicles (LUVs). The physicochemical properties of liposomes can be adjusted to optimize penetration through biological barriers and retention at the site of administration, and to reduce the likelihood of premature degradation and toxicity to non-target tissues. The optimal liposome properties depend on the route of administration: large-sized liposomes show good retention upon local injection, while small-sized liposomes are more suitable for passive targeting. PEGylation reduces the uptake of liposomes by the liver and spleen and prolongs circulation time, thereby increasing localization to inflamed sites due to the enhanced permeability and retention (EPR) effect. In addition, the liposome surface can be modified to achieve selective delivery of encapsulated drugs to specific target cells. Non-limiting examples of targeting ligands include monoclonal antibodies, vitamins, peptides, and polysaccharides that are specific for receptors concentrated on the surface of cells associated with the disease.
[0210] Non-limiting examples of dosage forms suitable for use in the present invention include liquids, elixirs, nanosuspensions, aqueous or oily suspensions, drops, syrups, and any combination thereof.
