報告摘要:
Plant natural products may occupy parts of the chemical space largely unexplored by screening of available pharmaceutical libraries while at the same time adhering to ‘drug-likeness’ descriptors. While there remains interest in developing small molecule drugs for cancer, exploring large numbers and diverse types of druglike compounds is a challenge. However, new chemical leads can be identified from traditional medicines, where long-standing ethnobotanical usage supports more detailed investigation. Scutellaria barbata D. Don is a key medicinal plant species in the Lamiaceae (the mint family) and the aerial parts have been used traditionally for treating cancer in many Asian countries, where it is known as Ban Zhi Lian (半枝蓮). Scutebarbatine A is the major diterpenoid, produced in specialized large, peltate trichomes on leaves of S. barbata. It induces dose-dependent apoptosis, specifically in cancer cells. Comparison between the cytotoxicity of methanolic extracts of S. barbata leaves and decoctions (Ban Zhi Lian) prepared traditionally, showed substantially different chemical compositions and differential induction of apoptosis. Analyses suggest polyvalency between the constituents in both extracts, and ways to produce enhanced chemopreventive preparations for the treatment of cancer.
