The invention concerns a new process for the preparation of high purity diacerein, by oxidisation of the protected aloe-emodin in the presence of an oxidising system and radical catalyst and subsequent substitution of the protector groups with acetyl groups.

aloe-emodin were designed and synthesized. The anti-inflammatory activities of all synthesized derivatives were screened by evaluating their inhibitoryeffects on LPS-induced nitric oxide production in RAW264.7 macrophages. The preliminary structure-activity relationship was determined. Among them, 2i exhibited the best nitric oxide inhibitory activity (IC50 = 3.15 μM), with no obvious toxicity. Further evaluation
