Hodoodo CAT#: H202953

CAS#: 179545-77-8

Description: Tanomastat, also known as BAY 12-9566, is a biphenyl matrix metalloproteinase (MMP) inhibitor (MMPI) with potential antineoplastic activity. Tanomastat inhibits MMP-2, MMP-3, and MMP-9, inhibiting extracellular matrix degradation and potentially inhibiting angiogenesis, tumor growth and invasion, and metastasis. MMPs consist of at least 18 zinc-containing endo-proteinases that are capable of degrading collagen and proteoglycan.

More Info: Results of phase III clinical trials:  This drug, developed by Bayer, was entered into Phase III human clinical trials. However, Bayer decided to stop the trials due to negative results from other phase III trials in pancreatic and small cell lung cancer. It was concluded that BAY 12-9566 was generally well tolerated and at the time of the final analysis, there was no evidence of an impact of BAY 12-9566 on progression-free survival  or overall survival .   ( source: Gynecol Oncol. 2006 Aug;102(2):300-8.
