Thioridazine is a chemical compound characterized by its potent anti-psychotic and anti-anxiety activities. As an antagonist of the dopamine receptor D2 family proteins, it exhibits a strong inhibitory effect on the PI3K-Akt-mTOR signaling pathways, resulting in anti-angiogenic effects. It also demonstrates significant antiproliferative and apoptosis induction effects in a diverse range of cancer cells, specifically targeting cancer stem cells (CSCs) [1] [2] [3] [4].
