How to use

In Vitro:

AZ3451 is a PAR2 antagonist that plays a part in inflammation response, apoptosis, autophagy and cellular senescence during Osteoarthritis (OA). AZ3451 prevents the IL-1β-induced inflammation response, cartilage degradation and premature senescence in chondrocytes. AZ3451 attenuates chondrocytes apoptosis by activating autophagy in vitro. The P38/MAPK, NF-κB and PI3K/AKT/mTOR pathways are involved in the protective effect of AZ3451.

In Vivo:

Intra-articular injection of AZ3451 can ameliorate the surgery induced cartilage degradation in rat Osteoarthritis (OA) model.
