Stilonium Iodide (also known as MG 624) is a trimethylethanaminium derivative with ganglionic-blocking action. Stilonium Iodide acts as α7-nicotinic receptor antagonist and Stilonium Iodide inhibits transmission between preganglionic and postganglionic neurons in the Autonomic Nervous System. Stilonium Iodide inhibits nicotine-induced proliferation and angiogenesis in human microvascular endothelial cells of the lung. Stilonium Iodide displayed anti-angiogenic activity in Matrigel, rat aortic ring and rat retinal explant assays. Furthermore, MG624 suppressed angiogenesis of NCI-H69 human SCLC tumors in vivo in both the chicken chorioallantoic membrane (CAM) and nude mice model.
