Tesmilifene(CAT: I011418) is a novel small molecule that exhibits selective targeting of multiple-drug resistant (MDR) tumor cells. It works by sensitizing these resistant cells to chemotherapy, thereby enhancing the efficacy of chemotherapy treatments. Tesmilifene has shown potential clinical benefits in various tumor types and is being investigated in combination with different chemotherapeutic regimens. By overcoming drug resistance mechanisms in tumor cells, tesmilifene offers a promising approach to improve the effectiveness of chemotherapy and potentially enhance treatment outcomes in cancer patients.
