Matrix metalloproteinase-13 (MMP-13) is a key enzyme implicated in the degradation of the extracellular matrix in osteoarthritis (OA). For this reason, MMP-13 synthetic inhibitors are being sought as potential therapeutic agents to prevent cartilage degradation and to halt the progression of OA. Herein, we report the synthesis and in vitro evaluation of a(More)
New fluorescent ligands for adenosine receptors (ARs), obtained by the insertion, in the N(6) position of NECA, of NBD-moieties with linear alkyl spacers of increasing length, proved to possess a high affinity and selectivity for the A(3) subtype expressed in CHO cells. In fluorescence microscopy assays, compound 2d, the most active and selective for human(More)
Structural manipulation of the pharmacophoric model of type A selective MMP inhibitors (MMPi), obtained by the insertion of some alkyl substituents R2 possessing an appropriate geometry, steric bulkiness and lipophilicity, is able to improve potency, in the subnanomolar range on MMP-2, and to give a good MMP inhibition on MMP-14 (MT1-MMP) in the designed(More)
Slowing FAP progression: Tafamidis meglumine is a small molecule capable of stabilizing the transthyretin (TTR) tetramer. Tafamidis acts in a similar way to the natural hormone T4, prevents TTR amyloid fibril formation, and offers a potential alternative to liver transplantation for the treatment of patients with TTR familial amyloid polyneuropathies(More)
Aggrecanases, in particular aggrecanase-2 (ADAMTS-5), are considered the principal proteases responsible for aggrecan degradation in osteoarthritis. For this reason, considerable effort has been put on the discovery and development of aggrecanase inhibitors able to slow down or halt the progression of osteoarthritis. We report herein the synthesis and(More)
Matrix metalloproteinases (MMPs) have been shown to be involved in tumor-induced angiogenesis. In particular, MMP-2, MMP-9, and MMP-14 have been reported to be crucial for tumor angiogenesis and the formation of metastasis, thus becoming attractive targets in cancer therapy. Here, we report our optimization effort to identify novel(More)
Activated leukocyte cell adhesion molecule (ALCAM) is expressed at the surface of epithelial ovarian cancer (EOC) cells and is released in a soluble form (sALCAM) by ADAM-17-mediated shedding. This process is relevant to EOC cell motility and invasiveness, which is reduced by inhibitors of ADAM-17. In addition, ADAM-17 plays a key role in EGFR signaling and(More)
Activated leukocyte cell adhesion molecule (ALCAM) plays a relevant role in tumor biology and progression. Our previous studies showed that ALCAM is expressed at the surface of epithelial ovarian cancer (EOC) cells and is released in a soluble form by ADAM-17-mediated shedding. This process is relevant to EOC cell motility and invasiveness, which is reduced(More)
Transthyretin (TTR) is one of thirty non-homologous proteins whose misfolding, dissociation, aggregation, and deposition is linked to human amyloid diseases. Previous studies have identified that TTR amyloidogenesis can be inhibited through stabilization of the native tetramer state by small molecule binding to the thyroid hormone sites of TTR. We have(More)
Some optically active 3-(arylmethylidene)aminoxy- (3a-g, 4a-g) and fluorenylideneaminoxy-2-methylpropionic acids (5, 6), were prepared as analogues of the antiinflammatory arylpropionic acids of type B, in which the aromatic group is substituted by an MAOM moiety. Some of the new compounds, tested in vivo for their antiinflammatory properties by means of(More)
