In Vitro | In vitro activity: Diacerein significantly inhibits LPS-induced IL-1beta production by synovial tissue and cartilage. Diacerein (1 μM) has a significantly less inhibitory effect on cartilage synthesis than culture media containing LPS only. Diacerein (1 μM) decreases NO release in synovial tissue and cartilage media and increases IL-1ra levels in cartilage culture media. Diacerein (10 μM) enhances the expression of TGF-beta1 and TGF-beta2 in cultured bovine articular chondrocytes. Diacerein reduces, in a dose-dependent manner, the interleukin-1-beta (IL-1beta)-induced MMP-13 production in osteoarthritic subchondral bone. Diacerein significantly reduces the activity of MMP-13 and cathepsin K in osteoclasts. Diacerein effectively blocks the IL-1beta effect on the osteoclast differentiation process and the survival of mature osteoclasts. |

In Vivo | Diacerein (100 mg/kg/day) significantly suppresses the paw edema and the increase in serum mucoprotein in the adjuvant-induced arthritic rats. Diacerein (30 mg/kg/day) combined with Naproxen (3 mg/kg/day) results in significantly greater anti-inflammatory activity than with naproxen alone in the adjuvant-induced arthritic rats. Diacerein (100 mg/kg/day) also significantly prevents bone loss and reduces the serum alkaline phosphatase and decreases the excretion of urinary hydroxyproline in the ovariectomized rats. Diacerein (25 mg/kg) decreases the thickness of cartilage and subchondral bone in the lesion (middle) zone of the lateral tibial plateau in Merino wethers. |
