Description

[0001] Cross-references This application claims the benefit of U.S. Provisional Application Serial No. 63 / 583,688, filed on September 19, 2023, which is incorporated herein by reference in its entirety. Background Technology

[0002] Cancer is characterized by the development of abnormal cells that divide uncontrollably and have the ability to infiltrate and destroy normal body tissues. Cancer is a major public health problem in many parts of the world and is the second leading cause of death globally. However, due to current advances in cancer screening, treatment, and prevention, survival rates are improving for many types of cancer.

[0003] Transient receptor potential (TRP) channels are one of the largest groups of ion channels, and they are divided into six subfamilies (TRPV, TRPM, TRPA, TRPC, TRPP, and TRPML). TRP channels are cation-selective channels activated by a variety of physical (e.g., temperature, osmotic pressure, mechanical) and chemical stimuli. Transient receptor potential melastatin subfamily member 8 (TRPM8) is a member of the TRP channel family. TRPM8 can sense harmless cold (15–28 °C) (McKeny et al.). Nature 2002, 416 ,52; Peier et al. Cell 2002, 108 Temperature variations in two ranges: 705 and harmful cold (<15 °C), as well as temperature variations caused by chemical agents such as menthol and icilin (Chuang et al.). Neuron 2004, 43 ,859). Summary of the Invention

[0004] TRPM8 has been found to be expressed in a variety of cancers, particularly metastatic and drug-resistant cancers. In recent years, a growing body of literature has demonstrated that TRPM8 is involved in tumorigenesis and progression, and studies have found that TRPM8 expression is significantly upregulated in prostate cancer (PC) and many other tumors, indicating its important role in the development of human cancers. The accumulated evidence from the past decade strongly supports the hypothesis that TRPM8, which plays a significant role in thermoregulation, could be one of the most promising new therapeutic targets in cancer treatment.

A single mediator is designed to deliver a specific amount of each agent along with any pharmaceutically acceptable carrier or excipient. In some embodiments, the mediator is a tablet, capsule, pill, or patch. In other embodiments, the mediator is a solution or suspension.

[0126] The terms "non-fixed combination" or "component kit" refer to combinations of therapeutic agents disclosed herein administered simultaneously, in parallel, or sequentially to a patient as separate entities, without a specific time limit, wherein such administration provides a therapeutically effective level of two compounds within the body of the subject in need. The latter also applies to cocktail therapies, such as the administration of three or more active ingredients.

[0127] Example The invention is illustrated in more detail by the following embodiments, which should not be construed as limiting.

[0128] Example 1: Cell proliferation assay: Place 15 mL of cell culture medium in a T75 flask (Corning, 430639) and place the flask in a humidified 37°C / 5% CO2 incubator (ThermoFisher, 371) for 15 minutes to allow the culture medium to equilibrate to the appropriate pH and temperature.

[0129] Remove the frozen vials of cell stock from liquid nitrogen and thaw rapidly by gently agitating them in a 37°C water bath for 1–2 minutes. Then, clean them with 70% ethanol in a Class II biosafety cabinet before opening. Transfer dropwise the vial contents to 10 mL of cell culture medium in a sterile 15 mL conical tube (BD-Falcon, 352097). Centrifuge the cells at 200 xg for 5 minutes (Eppendorf, 5810R). Aspirate the supernatant and resuspend the cell pellet in 1 mL of fresh cell culture medium, then transfer it to a T75 flask containing cell culture medium.
