A new tetrahydroxybenzophenone from a marine-associated fungus of penicillium sp. and its potential antibacterial activity.
Penicillium species are renowned for their ability to produce a wide range of secondary metabolites with medicinal properties. In this study, compounds 1-10 were isolated from Penicillium sp. Z-16, of which compound 1 is a new benzophenone derivative named methyl 2-(2,6-dihydroxy-4-methylbenzoyl)-4,5-dihydroxy-3-methoxybenzoate. The chemical structure of 1 was determined through comprehensive spectroscopic analysis, including 1D, 2D NMR (HMBC, HSQC) and HRESIMS. In addition, six other known compounds (11-16) were isolated and identified from Penicillium sp. T-5-1. The antimicrobial activity tests demonstrated that compound 1 was moderately active against Candida albicans with a MIC value of 125 μg/mL, while compound 2 showed a MIC value of 62.5 μg/mL against Staphylococcus aureus.
期刊介绍：
The aim of Natural Product Research is to publish important contributions in the field of natural product chemistry. The journal covers all aspects of research in the chemistry and biochemistry of naturally occurring compounds.
The communications include coverage of work on natural substances of land and sea and of plants, microbes and animals. Discussions of structure elucidation, synthesis and experimental biosynthesis of natural products as well as developments of methods in these areas are welcomed in the journal. Finally, research papers in fields on the chemistry-biology boundary, eg. fermentation chemistry, plant tissue culture investigations etc., are accepted into the journal.
Natural Product Research issues will be subtitled either ""Part A - Synthesis and Structure"" or ""Part B - Bioactive Natural Products"". for details on this , see the forthcoming articles section.
All manuscript submissions are subject to initial appraisal by the Editor, and, if found suitable for further consideration, to peer review by independent, anonymous expert referees. All peer review is single blind and submission is online via ScholarOne Manuscripts.
