Ajulemic acid, a nonpsychoactive cannabinoid acid, suppresses osteoclastogenesis in mononuclear precursor cells and induces apoptosis in mature osteoclast-like cells.

Oral administration of ajulemic acid (AjA), a cannabinoid acid devoid of psychoactivity, prevents joint tissue injury in rats with adjuvant induced arthritis. Because activation of osteoclasts is central to the pathogenesis of bone erosion in patients with rheumatoid arthritis (RA), we investigated the influence of AjA on osteoclast differentiation and… CONTINUE READING
