D018373 - Peripheral Nervous System Agents > D001337 - Autonomic Agents > D010276 - Parasympatholytics D005765 - Gastrointestinal Agents Trimebutine maleate is an orally anti-tumor agent. Trimebutine maleate selectively suppresses stemness and proliferation of ovarian cancer stem cells (CSCs). Trimebutine maleate reduces the colonic muscle hypercontractility, modulates gastrointestinal motility, induces apoptosis and can be used for the research of glioma/glioblastoma and irritable bowel syndrome[1][2][3][4][5][6].
