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.

How to use

In Vitro:

Tasisulam also inhibits VEGF-, FGF- and EGF-induced endothelial cord Formation with EC50 of 47, 103, and 34 nM, respectively. Tasisulam induces morphologic features of vascular normalization, including increased pericyte coverage and decreased hypoxia.

In Vivo:

Tasisulam (25 or 50 mg/kg, i.v.) displays dose-dependent antitumor activity, induces apoptosis, and normalizes tumor-associated vasculature in the Calu-6 non–small cell lung xenograft model. Besides, Tasisulam displays potent antitumor activity across a range of in vivo xenografts, including colorectal (HCT-116), melanoma (A-375), gastric (NUGC-3), leukemia (MV-4-11), and pancreatic (QGP-1).
