摘　　要：Biflavonoids are divided in two classes:C-C type compounds represented by the dimeric compound amentoflavone and C-O-C-type compounds typified by hinokiflavone(HNK)with an ether linkage between the two connected apigenin units.This later sub-group of bisflavonyl ethers includes HNK,ochnaflavone,delicaflavone and a few other dimeric compounds,found in a variety of plants,notably Selaginella species.A comprehensive review of the anticancer properties and mechanism of action of HNK is provided,to highlight the anti-proliferative and anti-metastatic activities of HNK and derivatives,and HNK-containing plant extracts.The anticancer effects rely on the capacity of HNK to interfere with the ERK1-2/p38/NFκB signaling pathway and the regulation of the expression of the matrix metalloproteinases MMP-2 and MMP-9(with a potential direct binding to MMP-9).In addition,HNK was found to function as a potent modulator of pre-mRNA splicing,inhibit-ing the SUMO-specific protease SENP1.As such,HNK represents a rare SENP1 inhibitor of natural origin and a scaffold to design synthetic compounds.Oral formulations of HNK have been elaborated to enhance its solubility,to facilitate the compound delivery and to enhance its anticancer efficacy.The review shed light on the anticancer potential of C-O-C-type biflavonoids and specifically on the pharmacological profile of HNK.This compound deserves further attention as a regu-lator of pre-mRNA splicing,useful to treat cancers(in particular hepatocellular carcinoma)and other human pathologies.
