RESUMO
@#This study investigated the anti-angiogenic activities of two diarylheptanoids, together with a structure analogue, curcumin. The activity and toxicity of these three compounds were compared using transgenic zebrafish as in vivo model and human umbilical vein endothelial cell(HUVEC)as in vitro model. Anti-angiogenic index(AI)was used as the ratio between LC50 and EC50. The results suggested that in both in vitro and in vivo assay, curcumin exerted the most potent anti-angiogenic effect but with lowest toxicity among these compounds; Yakuchinone A was the second potent; Yakuchinone B has the lowest activity but with the highest toxicity in all three compounds. Taken together, curcumin was the best angiogenic inhibitor in these three diarylheptanoids.
RESUMO
Acetyl-11-keto-β-boswellic acid (AKBA) is one of the triterpenes in the gum resin of the Boswellia serrata and Boswellia carterii,also known as Salai guggal or Indian frankincense.There has been growing interst in anti-tumor activity of AKBA.This review will summarize the latest advances of AKBA on anti-tumor activity for the better understanding of this compound and its further applications.
