Hybrid isoquinolines from Thalictrum foetidum: a new type of aporphine inhibiting Staphylococcus aureus by combined mechanisms†
Abstract
Thalfoetines A–D (1–4), unique hybrid aporphine alkaloids with a C-7 aromatic unit formed by a new C–C bond linking two building blocks, were isolated from Thalictrum foetidum. Their structures were elucidated by extensive spectroscopic and computational analysis. They inhibited bacteria significantly, and compound 1 damaged the cell structure of Staphylococcus aureus and inhibited its DNA synthesis.
