Abstract
Fatty acid synthase FAS is considered as a novel drug target for the development of anticancer and antiobesity agents Bioassayguided fractionation of a nhexanesoluble extract prepared from the roots of Salvia miltiorrhiza Bunge Labiatae using an in vitro enzyme assay led to the isolation of five abietane diterpenoids 1516dihydrotanshinone I 1 cryptotanshinone 2 tanshinone I 3 tanshinone IIA 4 and dansenspiroketallactone 5 Compounds 1–5 were tested for their in vitro FAS inhibitory activity and except for compound 5 IC50 100 μM compounds 1–4 inhibited the enzyme activity with IC50 values ranging from 120 to 303 μM Our findings may be partially related to the anticancer activity of abietane diterpenoids from the plant suggesting a further study on the anticancer potential of tanshinone derivatives
