  New Quaternary Ammonium Oxicam Derivatives Targeted toward Cartilage:  Synthesis, Pharmacokinetic Studies, and Antiinflammatory Potency

  摘要：

  Analogues of nonsteroidal antiinflammatory drugs (NSAIDs) oxicams, in which the active group was linked to a quaternary ammonium function [(4-hydroxy-2-methyl-2H-1,2-benzothiazine-1,1-dioxide-3-carboxamido)2-methylpyridinium iodide or piroxicam-N+ and [3-(4-hydroxy-2-methyl-2H-1,2-benzothiazine-1,1-dioxide-3-carboxamido)propyl]trimethylammonium iodide or propoxicam-N+] were synthesized. Compounds were labeled with tritium for piroxicam-N+ and carbon-14 for propoxicam-N+. Pharmacokinetic studies conducted on rats showed that these molecules were able to highly concentrate in joint cartilages but their bioavailability by the oral way was low. Only propoxicam-N+ exhibited a sufficient water solubility to be administered intravenously. This molecule was able to restore proteoglycans biosynthesis in cultured articular chondrocytes treated with Interleukin-1 beta with an efficiency identical to that of indomethacin. These results suggest that the functionalization of oxicam derivatives by a quaternary ammonium group greatly increases their affinity toward articular cartilage without eliminating their pharmacological activity. New drugs synthesized according to this scheme could be useful to obtain a significant decrease of the efficient administered dose and consequently an attenuation of adverse effects such as digestive toxicity.

  A series of new oxicam derivatives bearing a quaternary ammonium (QA) moiety was synthesized and evaluated in vitro for antiosteoarthritis properties. Propyltrimethyl ammonium 3 and propyldie-thylmethyl ammonium 11 stimulated aggrecan expression and mitigated the inhibitory action of IL-1. QA derivative 3 also increased TGF-beta 2 and type II receptor expression. These results suggest that such derivatives may not only inhibit the osteoarthritis degradation process but also stimulate its regeneration. QA derivatives 3 and 11 offer potential for developing new therapeutic approaches to osteoarthritis treatment. (C) 2009 Elsevier Masson SAS. All rights reserved.
