Abstract:
Transient receptor potential vanilloid (TRPV) 4 belongs to the TRPV subfamily of TRP ion channels. TRPV4 channels play a critical role in chondrocytes and thus TRPV4 is an attractive target of Disease-Modifying Osteoarthritis Drugs (DMOADs). Initial investigations of small molecules by Glaxo Smith Klein (GSK) as both agonists and antagonists via oral/intravenous administration have led to the use of existing agonists as lead compounds for biological studies. Our recent results suggest that local injection of a TRPV4 agonist is a potential treatment for osteoarthritis (OA). This review briefly summarizes updates regarding TRPV4 agonists based on recent advances in drug discovery, and particularly the local administration of TRPV4 agonists.
