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, 20.1μM), PSN-1 (PC₅₀, 9.7μM), MIA PaCa-2 (PC₅₀, 29.1μM), Capan-1 (73.0μM) and KLM-1 (25.9μM).
