Biological Activity

Description Diacerein is an inhibitor of pro-inflammatory cytokine Interleukin-1B (IL-1B) production, prescribed for osteoarthritis and chronic inflammatory arthritis.
In vitro

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. [1] Diacerein (10 μM) enhances the expression of TGF-beta1 and TGF-beta2 in cultured bovine articular chondrocytes. [2] 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. [3]

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. [4] 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. [5]

Bio Calculators

Molarity Calculator

Molarity Calculator

Calculate the mass, volume or concentration required for a solution. The Selleck molarity calculator is based on the following equation:

Mass (g) = Concentration (mol/L) × Volume (L) × Molecular Weight (g/mol)

  • Mass
    Molecular Weight

*When preparing stock solutions, please always use the batch-specific molecular weight of the product found on the via label and MSDS / COA (available on product pages).

Dilution Calculator

Dilution Calculator

Calculate the dilution required to prepare a stock solution. The Selleck dilution calculator is based on the following equation:

Concentration (start) x Volume (start) = Concentration (final) x Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2 ( Input Output )

  • C1

* When preparing stock solutions always use the batch-specific molecular weight of the product found on the vial label and MSDS / COA (available online).

Definitions of molecular mass, molecular weight, molar mass and molar weight:

Molecular mass (molecular weight) is the mass of one molecule of a substance and is expressed in the unified atomic mass units (u). (1 u is equal to 1/12 the mass of one atom of carbon-12)
Molar mass (molar weight) is the mass of one mole of a substance and is expressed in g/mol.
