Aggrecanase-2 inhibitors based on the acylthiosemicarbazide zinc-binding group
摘要:
Osteoarthritis is a disabling disease characterized by the articular cartilage breakdown. Aggrecanases are potential therapeutic targets for the treatment of this pathology. At the starting point of this project, an acylthiosemicarbazide was discovered to inhibit aggrecanase-2. The acylthiosemicarbazide Zn binding group is also a convenient linker for library synthesis. A focused library of 920 analogs was thus prepared and screened to establish structure-activity relationships. The modification of the acylthiosemicarbazide was also explored. This strategy combining library design and discrete compounds synthesis yielded inhibitor 35, that is highly selective for aggrecanases over a panel of metalloproteases and inhibits the degradation of native fully glycosylated aggrecan. A docking study generated binding conformations explaining the structure activity relationships. (C) 2013 Elsevier Masson SAS. All rights reserved.

Application of microwave technique allowed to accomplish novel, general and “greener” one‐pot protocol for the synthesis of isothiocyanates from amines. Reactions are easily scalable and take place without racemization of chiral amines. Decomposition of the intermediate dithiocarbamates into isothiocyanates proceeds without any additional desulfurating agent under these conditions.
In order to systematically explore and better understand the structure-activityrelationship (SAR) of a diarylmethane backbone in the design of potent uric acid transporter 1 (URAT1) inhibitors, 33 compounds (1a–1x and 1ha–1hi) were designed and synthesized, and their in vitro URAT1 inhibitory activities (IC50) were determined. The three-round systematic SAR exploration led to the discovery of a highly

Aberrant activation of NLRP3inflammasome is present in a subset of acute and chronic inflammatory diseases. The NLRP3inflammasome has been recognized as an attractive therapeutic target for developing novel and specific anti-inflammatory inhibitors. Cellular structure-activity relationship-guided optimization resulted in the identification of 4-oxo-2-thioxo-thiazolidinone derivative 9 as a selective
