Abstract
Targeting drug-resistant Acinetobacter baumannii, two fungal strains, Epicoccum sp. 1-042 and Penicillium sp. 19-115, were identified from 35 fungi isolated from Tibet. Bioassay-guided isolation from Epicoccum sp. 1-042 yielded a novel cyclohexenone, epiconone (1), and parasitenone (2), while patulin (3) was isolated from Penicillium sp. 19-115. Structural elucidation was accomplished through comprehensive spectroscopic analysis and quantum chemistry calculations. The biosynthetic pathways of compounds 1 and 2 were proposed based on bioinformatics analysis. Compounds 1 - 3 exhibited antibacterial activity against carbapenem-resistant Acinetobacter baumannii (CRAB) with MIC values ranging from 4 to 128 μg mL-1.
期刊介绍：
The Journal of Antibiotics seeks to promote research on antibiotics and related types of biologically active substances and publishes Articles, Review Articles, Brief Communication, Correspondence and other specially commissioned reports. The Journal of Antibiotics accepts papers on biochemical, chemical, microbiological and pharmacological studies. However, studies regarding human therapy do not fall under the journal’s scope. Contributions regarding recently discovered antibiotics and biologically active microbial products are particularly encouraged. Topics of particular interest within the journal''s scope include, but are not limited to, those listed below:
Discovery of new antibiotics and related types of biologically active substances
Production, isolation, characterization, structural elucidation, chemical synthesis and derivatization, biological activities, mechanisms of action, and structure-activity relationships of antibiotics and related types of biologically active substances
Biosynthesis, bioconversion, taxonomy and genetic studies on producing microorganisms, as well as improvement of production of antibiotics and related types of biologically active substances
Novel physical, chemical, biochemical, microbiological or pharmacological methods for detection, assay, determination, structural elucidation and evaluation of antibiotics and related types of biologically active substances
Newly found properties, mechanisms of action and resistance-development of antibiotics and related types of biologically active substances.
