[0001] This application claims priority to U.S. Provisional Application No. 63 / 619,000, filed January 9, 2024, the entire contents of which are incorporated herein by reference. Background Technology

[0002] The transcription factor TP53 acts as a tumor suppressor gene and is inactivated by mutations in approximately 50% of all tumors. TP53 regulates multiple intracellular metabolic pathways, including DNA damage repair, apoptosis, and senescence. The Y220C mutation is a common TP53 missense mutant, associated with over 100,000 new cancer cases globally each year, primarily breast and ovarian cancer. The Y220C mutation results in a significant structural change in the TP53 protein and is known to form a novel protein cavity estimated to accommodate small molecule drug candidates. Crucially, the mutation-induced cleft is located away from the TP53 surface involved in DNA recognition or protein-protein interactions, enabling the development of targeted chemotherapeutic agents that stabilize the DNA-binding domain without interfering with its natural substrate binding. Stabilization can restore TP53 function, thereby reactivating the TP53 tumor suppressor gene pathway and shrinking or killing tumors. Summary of the Invention

[0003] This article provides compounds having formula I: (I); and pharmaceutically acceptable salts and compositions thereof, wherein R 1 R 2 R 3 A, X, Y, and Z are as described herein. In one aspect, the disclosed Formula I compound and its pharmaceutically acceptable salt are used as covalent modifiers of TP53 Y220C. In one aspect, the disclosed Formula I compound and its pharmaceutically acceptable salt stabilize TP53 Y220C. In one aspect, the disclosed Formula I compound and its pharmaceutically acceptable salt restore the function of the wild-type tumor suppressor protein TP53 (WT TP53).

"Enrichment of the indicated configuration relative to the opposite configuration" is a molar percentage and is determined by dividing the number of compounds having the indicated stereochemical configuration at the chiral center by the total number of all compounds in the mixture having the same or opposite stereochemical configurations.

[0024] When geometric isomers are described by name or structure, the indicated isomer has an enrichment relative to the opposite isomer greater than 50%, 60%, 70%, 80%, 90%, 99%, or 99.9%. "Enrichment of the indicated isomer relative to the opposite isomer" is a molar percentage, determined by dividing the number of compounds having the indicated geometry by the total number of all compounds in the mixture having the same or opposite geometry.

[0025] When a disclosed compound is named or described by its structure without indicating its stereochemistry, it should be understood that the name or structure covers one of the possible stereoisomers or geometric isomers without other isomers, or a mixture of the stereoisomers or geometric isomers covered.

[0026] The terms "subject" and "patient" are used interchangeably and refer to mammals in need of treatment, such as companion animals (e.g., dogs, cats, etc.), farm animals (e.g., cattle, pigs, horses, sheep, goats, etc.), and laboratory animals (e.g., rats, mice, guinea pigs, etc.). Typically, a subject is a person in need of treatment.

[0027] The terms “inhibition,” “hindrance,” or “inhibitory” include a reduction in the baseline activity of a biological activity or process.

[0028] As used herein, the terms “treatment,” “management,” and “curing” refer to reversing, alleviating, delaying the onset of a disease or disorder or one or more symptoms thereof as described herein, or inhibiting its progression. In some respects, treatment may be administered after one or more symptoms have appeared, i.e., therapeutic treatment. In other respects, treatment may be administered even when there are no symptoms. For example, susceptible individuals may be treated before symptoms appear (e.g., based on a history of symptoms and / or based on exposure to a specific organism or other susceptibility factor), i.e., preventative treatment. Treatment may also continue after symptoms have disappeared, for example, to delay recurrence.

[0029] The term "pharmaceutically acceptable carrier" refers to a non-toxic carrier, adjuvant, or loading agent that does not impair the pharmacological activity of the compound formulated with it. Pharmaceutically acceptable carriers, adjuvants, or loading agents that can be used in the compositions described herein include, but are not limited to, ion exchangers, alumina, aluminum stearate, lecithin, serum proteins (such as human serum albumin), buffering substances (such as phosphates, glycine), sorbic acid, potassium sorbate, mixtures of partial glycerides of saturated vegetable fatty acids, water, salts or electrolytes (such as protamine sulfate, disodium hydrogen phosphate, potassium hydrogen phosphate, sodium chloride, zinc salts), colloidal silica, magnesium trisilicate, polyvinylpyrrolidone, cellulose-based substances, polyethylene glycol, sodium carboxymethyl cellulose, polyacrylates, waxes, polyethylene-polyoxypropylene-block polymers, polyethylene glycol, and lanolin.

[0030] For use in pharmaceuticals, the salts of the compounds described herein refer to non-toxic, pharmaceutically acceptable salts.

[0168] Bioassay The efficacy of the compound (IC50) was evaluated in a TR-FRET binding assay measuring the binding of the biotinylated small molecule probe BP1 to the Y220C TP53 mutant DBD. 50 Specifically, 5 μL of a mixture (consisting of 32 nM BP1 and 48 nM streptavidin-d2 (Cisbio) at pH 7.2, 10 mM KH2PO4, 150 mM NaCl, 0.01% BSA, 0.01% Tween-20, and 0.1 mM TCEP) was added to a 384-well plate containing the test compound in 60 nL DMSO (0.6% fc .DMSO (v / v)) for repeated 10-point dose-response titrations. An additional 5 μL of mixture was added to a 384-well plate. This mixture consisted of 10 nM Y220C TP53 DBD (expressed in *E. coli*, His-TEV-P89-T312-FLAG; Uniprot ID P04637-1) in 10 mM KH2PO4 at pH 7.2, 0.3 nM Mab anti-FLAG M2-Tb cavitation compound (Perkin Elmer), 150 mM NaCl, 0.01% BSA, 0.01% Tween-20, and 0.1 mM TCEP. The mixture was incubated at 20 °C. The TR-FRET reaction was monitored after 4 h and 24 h of incubation with the BP1 mixture and the compound mixture. The plates were read using an EnVision plate reader (Perkin Elmer) at Ex / Em 615 / 665. To determine the potency (IC50) of the test compound...50 (Competitively binding to TP53 Y220C protein in the presence of the biotinylated probe BP1), the TR-FRET ratio was normalized to the mean ratio (0% inhibition) of the DMSO control wells and the mean minimum ratio (100% inhibition) obtained using the 5 μmol BP1 positive control compound. The dose-response of the test compounds was fitted using a nonlinear regression with 4-parameter fitting, providing IC50. 50 Values ​​and nHill slope. The results are shown in Table 1 below and expressed in the ranges described here: A: IC 50 <0.100 μM; % inhibition >90%; B:IC 50 =0.100-1.00 μM; %inhibition = 70-90%; C:IC 50 =1.00-10.0 μM; %inhibition = 50-70%; D:IC 50 =10.0-60.0 μM; %inhibition =10-50%; E:IC 50 >60.0 μM; % inhibition <10%.

[0169] The TR-FRET assay described above can be used to evaluate the binding affinity of reversible and covalent TP53 Y220C ligands, stabilizers, and correctors, and can also distinguish between them. To validate the TR-FRET assay described above, we characterized TP53 Y220C ligands, stabilizers, and correctors previously described in the scientific literature. (By Joerger et al.) ACS Chem. Biology Compounds PK9301 and PK9323, described in (2020, 15, 657-668), have been shown by X-ray crystallography to bind to TP53 Y220C, and their stability in the mutant protein was determined by differential scanning fluorometry (DSF). In the aforementioned TR-FRET binding assay, their IC50 values ​​were [missing information]. 50 =1.5 μM and 4.1 μM respectively. Jeorger, Boeckler et al. ( J. Am. Chem. Soc. Compound PK5196, described in 2012, 134, 6810-6818, has been shown by X-ray crystallography to bind to TP53 Y220C, and its stability to the mutant protein has been determined by differential scanning fluorometry (DSF), nuclear magnetic resonance (NMR), and isothermal calorimetry (ITC). In the aforementioned TR-FRET assays, IC5196 showed a high efficiency of 100%. 50 =9.7 μM. PK9301, PK9323, and PK5196 are all reversible TP53 Y220C ligands / stabilizers, and therefore exhibit time-independent activity in the above TR-FRET assays. The same or nearly identical IC50 values ​​were observed at 4 h and 24 h time points. 50Value. Covalent ligands / modifiers typically exhibit time-dependent activity because covalent modification of a protein produces a persistent, cumulative effect as the reaction with the target protein proceeds. Compounds of Formula I typically exhibit a time-dependent shift of the TR-FRET binding probe BP1 from TP53 Y220C, thus distinguishing it from reversible TP53 Y220C ligands / stabilizers / correctors. We believe that, in certain cases, covalent modification of mutant TP53Y220C may lead to more persistent stabilization of the mutant protein and result in a more robust recovery of wild-type TP53 function relative to reversible ligands. This covalent mechanism of action may be advantageous for small molecule therapies targeting medical conditions such as cancer associated with or attributable to the TP53 Y220C mutant protein.
