Dendroforin

Antimigration

H460

Lung cancer

Lung cancer patients have high mortality rate due to the high incidence rate of metastasis.To achieve metastasize,cancer cells require an ability to migrate from initial to secondary site.Therefore,the promising compound with antimigrating effect might be a beneft for cancer metastasis[1].Dendroforin,a potential active polyphenol compound,is extracted from Dendrobium brymerianum found in Thailand,Burma,Laos,and China.Previous studies showed that some Dendrobium species exhibit the potential sources of cytotoxic compounds[2,3].Dendroforin has been identifed from this plant and investigated for cytotoxic and antimigratory activities in this study.The results showed that dendroforin has signifcant cytotoxic effect against human lung cancer H460 cells,showing 80%inhibition at a concentration of 15 μg/mL(IC50=124.77±3.63 μg/mL).Additionally,wound healing assay reveals that dendroforin is able to suppress lung cancer migration.This study suggests that dendroforin might be a potential compound for attenuation of lung cancer metastasis.
