Dose–response curves of ten oligostilbenes and diacerein. Chondrocytes were treated with 10 ng/mL IL-1β and different concentrations of drug for 24 h. The chondrocytes’ absorbance values were measured by CCK-8. The abscissa represents the base-10 logarithm of drug concentration, and the ordinate represents the proliferative activity of drug, which was calculated according to the formula: (Experimental group − IL-1β group)/(untreated control group − IL-1β group). Data presented are the average of triplicates. Prism 6 was used to fit the curve and to calculate EC50
