Streptozotocin (U-9889) is a small molecule, N-nitroso-containing antibiotic and a potent DNA methylating agent. Streptozotocin (U-9889) acts as a nitric oxide (NO) donor and vasorelaxant. In rat cell studies, this compound presented significant methylation of the liver, kidney, and pancreatic cells and selectivity for these cells against the more general methylating activity of the aglycone analog N-methyl-N-nitrosourea (sc-212238). Streptozotocin shows particular activity in the pancreas, and has been used both to induce diabetes in mammals and to treat human pancreatic cancers. Streptozotocin (U-9889) is an inhibitor of NCOAT.
