PI3K inhibitor
PI3K (phosphoinositide 3-kinase) inhibitors are a class of drugs that target the PI3K enzyme, which plays a critical role in cell signaling pathways involved in cell growth, survival, and metabolism. PI3K enzymes are divided into classes based on their structure and function, with class I PI3Ks being particularly relevant in cancer and other diseases. By inhibiting PI3K activity, these inhibitors disrupt signaling cascades that promote cell proliferation and survival, thereby slowing down or halting the growth of cancer cells. PI3K inhibitors are a focus of cancer research and therapy development, aiming to provide targeted treatment options for various cancers where PI3K pathway dysregulation is implicated, such as breast cancer, colorectal cancer, and certain types of leukemia.
