Colosseum Combinatorial Chemistry Centre for Technology (C4T SCarl), Via della Ricerca Scientifica snc, I-00133 Rome, Italy.Bioorganic & medicinal chemistry (Impact Factor: 2.79). 02/2012; 20(7):2323-37. DOI: 10.1016/j.bmc.2012.02.010
Among matrix metalloproteinases (MMPs), gelatinases MMP-2 (gelatinase A) and MMP-9 (gelatinase B) play a key role in a number of physiological processes such as tissue repair and fibrosis. Many evidences point out their involvement in a series of pathological events, such as arthritis, multiple sclerosis, cardiovascular diseases, inflammatory processes and tumor progression by degradation of the extracellular matrix. To date, the identification of non-specific MMP inhibitors has made difficult the selective targeting of gelatinases. In this work we report the identification, design and synthesis of new gelatinase inhibitors with appropriate drug-like properties and good profile in terms of affinity and selectivity. By a detailed in silico protocol and innovative and versatile solid phase approaches, a series of 4-thiazolydinyl-N-hydroxycarboxyamide derivatives were identified. In particular, compounds 9a and 10a showed a potent inhibitory activity against gelatinase B and good selectivity over the other MMP considered in this study. The identified compounds could represent novel potential candidates as therapeutic agents.

ABSTRACT: Introduction: The MMPs are involved in tissue remodeling. An imbalance between the inhibition and activation of MMPs results in excessive degradation of the extracellular matrix, which leads to some diseases including cancer, rheumatoid arthritis, osteoarthritis, heart disease and neurodegenerative diseases such as stroke. In this review, recent advances in the research of MMP inhibitors are reviewed. Areas covered: This updated review summarized new patents on MMP inhibitors within January 2011 - December 2013. Expert opinion: This review gives the latest development in the area of MMP inhibitors, which aim to treat disease processes associated with the MMPs. Structure-based design techniques have been used successfully in the search of selective MMP inhibitors, and these inhibitors can also be derived from natural products. Furthermore, imaging 'in vivo' technologies have been developed in order to follow the drug distribution to the targeted tissues, and to quantify the drug efficiency.Expert Opinion on Therapeutic Patents 08/2014; 24(9).
