Three new sesquilignans (Eleutherocosus A (1), Eleutherocosus B (2) and Eleutherocosus C (3)) and seven known lignans (4-10) were isolated from the EtOAc-soluble extract of Eleutherococcus senticosus. The structures were determined through spectroscopic and physicochemical analyses. The inhibitory activity of all isolates against DGAT1 and DGAT2 was evaluated. Compounds 1-3 exhibited the most potent inhibitory activity against DGAT1 with IC50 values of 71.4 +/- 1.3, 79.1 +/- 1.1, and 65.2 +/- 1.2 μM, respectively.
Three new sesquilignans, Eleutherocosus A (1), Eleutherocosus B (2) and Eleutherocosus C (3) together with seven known lignans (4 -10) were isolated from the EtOAc-soluble extract of Eleutherococcus senticosus. Their structures were elucidated by the basis of spectroscopic and physicochemical analyses. All the isolates were evaluated for in vitro inhibitory activity against DGAT1 and DGAT2. Among them, compounds 1 -3 exhibited the most potent inhibitory activity on DGAT1 with IC50 values of 71.4 +/- 1.3, 79.1 +/- 1.1 and 65.2 +/- 1.2 mu M, respectively.
