Cancer is an intractable disease for humans to overcome. Recently natural products or Oriental prescriptions have been on the spotlight to develop anticancer agents with little side-effects and good efficacy. KamikeKyuktang has been used for the treatment of cancer in Oriental medicine. However, its anti-cancer mechanism still remains unclear. KMKKTE is an ethanol extract of KamikeKyuktang composed of 12 medicinal herbs. Anti-proliferative effects of KMKKT was investigated on Lewis lung carcinoma cell (LLC) and A549 (human lung cancer cells). Half-maximal inhibition of the LLC and A549 cell proliferation by KMKKTE was found approximately 125㎍/㎖ and 250㎍/㎖, respectively. It also effectively inhibited the proliferation of HUVEC cells treated by bFGF and VEGF up to 30% of control at 125㎍/㎖ and the cell migration to 80% at 25 ㎍/㎖ in concentration dependent manner. Tube formation of HUVEC cells on matrigel also was significantly suppressed from 25㎍/㎖ of KMKKTE. Taken together, these results demonstrate that KMKKTE has antiangiogenic activity and be applied to angiogenesis dependent cancers.
