A series of 1-sulfonylaminocyclopropanecarboxylates was synthesized as ADAMTS-5 (Aggrecanase-2) inhibitors. After an intensive investigation of the central cyclopropane core including its absolute stereochemistry and substituents, we found compound 22 with an Agg-2 IC50=7.4 nM, the most potent ADAMTS-5 inhibitor reported so far.

Background: This study aimed to investigate the impact of AM1241 on lipopolysaccharide (LPS)-induced chondrocyte inflammation in mice and its potential mechanism for improving osteoarthritis (OA).
Methods: The OA mice model was established employing the refined Hulth method. The impact of different concentrations of AM1241 on mice chondrocyte activity was detected using CCK-8.

Osteoarthritis is a degenerative disease of cartilage, and exosome derived from mesenchymal stem cells (MSCs) are considered promising for treating inflammatory musculoskeletal disorders, although their mechanisms are not fully understood. This study aimed to investigate the effects of exosomes derived from canine bone marrow mesenchymal stem cells (cBMSCs-Exos) on the expression of inflammatory factors and genes related cartilage matrix metabolism in IL-1β-induced canine chondrocytes. Canine BMSCs were isolated and characterized for surface markers and trilineage differentiation.

M6495 is a first-in-class NANOBODY molecule and an inhibitor of ADAMTS-5, with the potential to be a disease modifying osteoarthritis drug. In order to investigate the PK/PD (pharmacokinetic and pharmacodynamic) properties of M6495, a single dose study was performed in cynomolgus monkeys with doses up to 6 mg/kg, with the goal of understanding the PK/PD properties of M6495. The neo-epitope ARGS (Alanine-Arginine-Glycine-Serine) generated by cleavage of aggrecan by ADAMTS-5 was used as a target-engagement biomarker.
