Inhibition of Helicobacter pylori and gastric cancer cells by lipid aldehydes from Viburnum opulus (Adoxaceae)

A unique group of bioactive, naturally occurring lipid aldehydes were isolated from the fruits of Viburnum opulus, (family Adoxaceae). The natural occurrences of these fatty acid derived aldehydes are reported here for the first time. Helicobacter pylori is a prevalent gastroduodenal pathogen, a causal agent of chronic gastritis and peptic ulcers and an important co-factor in gastric cancer development. We investigated the chemistry and bioactivity of these active constituents by evaluating their ability to inhibit the growth of H. pylori and to induce apoptosis in a gastric cancer cell line (CRL-5971) in vitro.
