Description: Tasisulam, also known as LY573636, is an acyl-sulfonamide with potential antineoplastic activity. Selectively toxic towards tumor cells, tasisulam appears to induce tumor cell apoptosis by a mitochondrial-targeted mechanism involving the loss of mitochondrial membrane potential and induction of reactive oxygen species (ROS). In combination with an angiogenesis inhibitor, this agent may exhibit synergistic antiangiogenic activity.
