Identification of Novel Matrix Metalloproteinase Inhibitors by Screening of Phenol Fragments Library

In the last 20 years, a great variety of synthetic, low molecular weight MMP inhibitors (MMPIs) have been synthesized and tested, although none has reached clinical utility. Exploration of novel ZBGs and development of non-hydroxamate MMPI has become a focus in current research. It's well-known that polyphenols can produce beneficial effects on human health by their antioxidant properties as well as they have the ability to block gelatinase activity. In this work we tested a series of selected phenols as MMP inhibitors. The most interesting hit (B6) shows sub-micromolar activity against MMP-2 (IC(50) 0.59 ± 0.05 µM, LE = 1.07) and a fairly good selectivity spectrum.
