Abstract: The present invention provides uses of an andrographolide derivative in preparation of a medicament for preventing and treating inflammatory bowel disease. The andrographolide derivative AL-1 has the mechanisms, for the treatment of ulcerative colitis, of scavenging of free radicals, inhibition of NF-?B signaling pathway activation and COX-2 expression, activation of PPAR-? expression, and thus can prevent the transcription and expression of inflammatory-related genes to improve the conditions of inflammation. AL-1 can be used as a medicine for the treatment of inflammatory bowel disease and can be formulated to various dosage forms with a pharmaceutically acceptable carrier.

Abstract: The present invention relates to the use of ligustrazine nitrone derivatives and pharmaceutical composition thereof for the treatment and prevention of diseases of diabetic complications, which include renal anemia. The ligustrazine nitrone derivatives have the structure of the general formula (I). Experimental results indicated that the ligustrazine nitrone derivatives can significantly increase the levels of serum iron and erythropoietin in STZ induced SD rats and spontaneously hypertensive rats, and can be used for treating and preventing renal anemia caused by decrease in renal EPO production and/or concomitant iron deficiency. Therefore, the ligustrazine nitrone derivatives can be made into various dosage forms with a drug carrier. The derivatives can be prepared into various dose forms together with drug carriers.
