Genome mining of a prenylated and immunosuppressive polyketide from pathogenic fungi.
نویسندگان
چکیده
Activation of the polycyclic polyketide prenyltransferase (pcPTase)-containing silent clusters in Aspergillus fumigatus and Neosartorya fischeri led to isolation of a new metabolite neosartoricin (3). The structure of 3 was solved by X-ray crystallography and NMR to be a prenylated anthracenone. 3 exhibits T-cell antiproliferative activity with an IC(50) of 3 μM, suggestive of a physiological role as an immunosuppressive agent.

Polyketides draw much attention because of their potential use in pharmaceutical and biotechnological applications. This study identifies an abundant pool of polyketide synthase (PKS) genes from local isolates of tropical fungi found in Thailand in three different ecological niches: insect pathogens, marine inhabitants, and lichen mutualists. We detected 149 PKS genes from 48 fungi using PCR wi...
متن کاملRecent developments in Pseudomonas biocontrol mechanisms
Fluorescent pseudomonads are an effective source of biological control that have high adaptive power and able to produce a wonderful source of secondary metabolites. Antibiotics such as phenazines, diacetylphloroglucinol, and hydrogen cyanide are produced by certain taxonomic groups of the genus Pseudomonas and appear to be ancestral. These compounds often play a physiological role in the produ...
متن کاملPolyketides, Toxins and Pigments in Penicillium marneffei
Penicillium marneffei (synonym: Talaromyces marneffei) is the most important pathogenic thermally dimorphic fungus in China and Southeastern Asia. The HIV/AIDS pandemic, particularly in China and other Southeast Asian countries, has led to the emergence of P. marneffei infection as an important AIDS-defining condition. Recently, we published the genome sequence of P. marneffei. In the P. marnef...
متن کاملGenetic analysis of polyketide synthase and peptide synthase genes of cyanobacteria as a mining tool for new pharmaceutical compounds
Cyanobacteria are considered a promising source for new pharmaceutical lead compounds and a large number of chemically diverse and bioactive metabolites have been obtained from cyanobacteria. Despite of several worldwide studies on prevalence of NRPSs and PKSs among the cyanobacteria, none of them included Iranian cyanobacteria of Kermanshah province. Therefore, the aim of this study was t...
متن کاملLow-Volume Toolbox for the Discovery of Immunosuppressive Fungal Secondary Metabolites
The secondary metabolome provides pathogenic fungi with a plethoric and versatile panel of molecules that can be deployed during host ingress. While powerful genetic and analytical chemistry methods have been developed to identify fungal secondary metabolites (SMs), discovering the biological activity of SMs remains an elusive yet critical task. Here, we describe a process for identifying the i...
