Abstract
Two new α-pyrones, pureones A (1) and B (2), one analog 6-carbomethoxymethyl-4-hydroxy-2-pyrone (3) (isolated as a natural product for the first time), together with 8-acetoxy pestalopyrone (4), 6-[(7S,8 R)-8-propyloxiran-1-yl]-4-methoxy-pyran-2-one (5), 6-pentyl-4-methoxy-pyran-2-one (6), pestalotin (LL-P880α) (7), LL-P880β (8) and annularin D (9) were identified from Purpureocillium sp. NBUF263, associated with an Ircinia sp. sponge from the mesophotic zone. The structures of all isolated compounds were elucidated by spectroscopic data analysis, and the absolute stereochemistry of 2 was determined by the modified Mosher's method. Compounds 2 and 3 exhibited root growth inhibition activities in Arabidopsis thaliana Columbia-0 model at 2.5 and 10.0 μM, respectively.
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.
