Abstract
Two new diterpenes, maderaspatins A (1) and B (2), and four known analogues (3–6) were isolated from an acetone extract of the roots of Grangea maderaspatana (L.) Poir. Their chemical structures were elucidated by the 1D and 2D NMR spectra, complemented by HR-ESI-MS data. The absolute configurations were determined through comparative analysis of experimental CD and calculated ECD spectra. The in vitro cytotoxic activity of purified compounds against the SW480 cell line were evaluated.
期刊介绍:
Phytochemistry Letters invites rapid communications on all aspects of natural product research including:
• Structural elucidation of natural products
• Analytical evaluation of herbal medicines
• Clinical efficacy, safety and pharmacovigilance of herbal medicines
• Natural product biosynthesis
• Natural product synthesis and chemical modification
• Natural product metabolism
• Chemical ecology
• Biotechnology
• Bioassay-guided isolation
• Pharmacognosy
• Pharmacology of natural products
• Metabolomics
• Ethnobotany and traditional usage
• Genetics of natural products
Manuscripts that detail the isolation of just one new compound are not substantial enough to be sent out of review and are out of scope. Furthermore, where pharmacology has been performed on one new compound to increase the amount of novel data, the pharmacology must be substantial and/or related to the medicinal use of the producing organism.
