Abstract

From the chloroform extract of the leaves of Uvaria dac, four new highly-oxygenated cyclohexene derivatives named uvaridacols I–L (1–4) were isolated together with nine previously reported compounds (5–13). Their structures were determined based on the extensive NMR spectroscopic data and circular dichroism spectroscopic analysis. Among the new compounds, uvaridacol L (4) displayed strong preferential cytotoxicity in the nutrient deprived medium against five different tested pancreatic cancer cell lines, PANC-1 (PC₅₀, 20.1 μM), PSN-1 (PC₅₀, 9.7 μM), MIA PaCa-2 (PC₅₀, 29.1 μM), Capan-1 (73.0 μM) and KLM-1 (25.9 μM).
