Design, synthesis and molecular modeling study of iminodiacetyl monohydroxamic acid derivatives as MMP inhibitors
摘要:
As the matrix metalloproteinases (MMPs) can be massively up-regulated in degenerative tissues and degrade the extracellular matrix, these key enzymes are promising targets for the therapy of cancer and other degenerative diseases. Here, we are presenting a series of new non-peptidic hydroxamate-based matrix metalloproteinase inhibitors, MMPIs, incorporating the iminodiacetic (IDA) hydroxamic acid scaffold, as mimics of truncated peptidic MMPIs. A series of alkylaryl and sulfonylaryl groups, on the IDA basic scaffold, was investigated with the aim of improving potency and selectivity against MMPs involved in degenerative diseases. The sulfonamide based IDA derivatives studied (compounds B1-B3) showed to be potent (nM range) against deep S1' pocket MMPs enzymes (i.e., MMP-2). (c) 2006 Elsevier Ltd. All rights reserved.

Matrix metalloproteinases (MMPs) and carbonic anhydrases (CAs) are two classes of zinc enzymes with different roles and catalytic targets, such as the degradation of most of the extracellular matrix (ECM) proteins and the regulation of the CO2/HCO3- equilibrium in the cells, respectively. Both families have isoforms which were proved to be involved in several stages of carcinogenic processes, and so the selective inhibition of these enzymes might be of interest in cancer therapy. We report herein the design, synthesis, and in vitro evaluation of a series Of Compounds possessing the iminodiacetic acid as the main backbone and two functional groups attached, namely, the hydroxamic acid and the arylsulfonamide (ArSO2NH2) moieties, to enable the inhibition of MMPs and CAs, respectively. These compounds were demonstrated to strongly inhibit both MMPs and CAs, some of them from the nanomolar to subnanomolar range. Furthermore, a docking study for MMPs was reported for the most promising compound in order to investigate its binding interactions with the different MMPs.
