description

Diterpenoids salvimulticanol (1) and salvimulticaoic acid (2) together with known diterpenoid (3-6) were isolated from Salvia multicaulis. Structures were elucidated by spectroscopic techniques including HRESIMS as well as 1D-, and 2D-NMR. In-vitro cytotoxicity was assayed against human cancer cell lines. As several metabolites exhibited activity against drug-resistance lines, compounds were screened against a panel of human drug-sensitive and multidrug-resistant cancer lines. A proposed biosynthetic pathway for these new diterpenoids (1-2) as well as the cytotoxic structure-activity relationship of all identified compounds were discussed. Compound 1 and 6 showed the most potent cytotoxicity with IC50 11.58 and 4.13 towards leukemia cell lines CCRF-CEM and CEM-ADR5000, respectively.
