INCB-057643 is a potent enzyme inhibitor with potential in cancer treatment, particularly for leukemia and lymphoma. It functions by inhibiting specific enzymes involved in the growth and survival of cancer cells, causing cancer cells to stop dividing and eventually die. Additionally, studies indicate it can be used in combination with other drugs to enhance treatment efficacy and reduce the risk of cancer cell resistance. Currently, it is in the research and clinical trial stages to evaluate its safety and efficacy in humans.
