Pardinumones A-D: Antibacterial Polyketide-Amino Acid Derivatives from the Mushroom Tricholoma pardinum.

ABSTRACT: Four polyketide-amino acid derivatives, pardinumones A-D (1-4), were isolated from the wild mushroom Tricholoma pardinum. Their structures together with absolute configurations were characterized by means of spectroscopic data analyses, as well as calculated electronic circular dichroism (ECD) and NMR with sorted training set (STS) protocol analysis. Compounds 1-4 exhibited antibacterial activity against Staphylococcus aureus, Staphylococcus epidermidis, and Escherichia coli with MIC values in the range of 6.25-50 μg/mL.

Moderate to good activity was seen against Gram-positive bacteria in vitro. One cyclohexyl-substituted compound 2c was tested more widely and showed good potency (MIC values ranging from 2-4 μg/mL) against antibiotic-resistant strains of Staphylococcus aureus and Enterococci (VRE, VSE), and against Staphylococcus epidermidis.

New Tricholidic Acid Triterpenoids from the Mushroom Tricholoma ustaloides Collected in an Italian Beech Wood.

Project description:The secondary metabolites produced by Tricholoma ustaloides Romagn., a mushroom species belonging to the large Tricholoma genus (Basidiomycota, Tricholomataceae), are unknown. Therefore, encouraged by the interesting results obtained in our previous chemical analyses of a few Tricholoma species collected in Italian woods, we aimed to investigate the secondary metabolites of Tricholoma ustaloides. The chemical analysis involved the isolation and characterization of secondary metabolites through an extensive chromatographic study. The structures of isolated metabolites, including the absolute configuration, were established based on a detailed analysis of MS, NMR spectroscopic, optical rotation, and circular dicroism data, and on comparison with those of related compounds reported in the literature. Two novel lanostane triterpenoids, named tricholidic acids B and C, together with triglycerides, a mixture of free fatty acids, five unidentified metabolites, and the known rare saponaceolides F and J, tricholidic acid, and tricholomenyn C, were isolated from an EtOAc extract of fruiting bodies of Tricholoma ustaloides that were collected in an Italian beech wood. This is the second example of isolation of tricholidic acid derivatives from a natural source. Saponaceolides F and J exhibited high cytotoxicity (IC50 values ≤ 10 μM) against a panel of five human cancer cell lines. The toxicity against myeloid leukemia (HL-60), lung cancer (A-549), hepatocellular cancer (HepG2), renal cancer (Caki-1), and breast cancer (MCF-7) cells was higher than that shown by the very well-known cytotoxic drug cisplatin.

Microsatellite markers for the prized matsutake mushroom (Tricholoma matsutake, Tricholomataceae).

Project description:Premise of the studyNovel and cost-effective microsatellite markers were developed to explore the population genetics, biogeographic structure, and evolutionary history of the prized Euro-Asian wild edible ectomycorrhizal fungus Tricholoma matsutake (Tricholomataceae).Methods and resultsEighteen new polymorphic simple sequence repeat loci, detected from a microsatellite-enriched genomic library, were used to characterize 131 individuals from eight T. matsutake populations. The number of alleles ranged from two to 10, with averages of 1.42 to 3.22. Levels of observed and expected heterozygosity ranged from 0.00-1.00 and from 0.00-0.83, with mean values of 0.21 and 0.26, respectively. In total, 50% of the loci showed interspecific transferability and polymorphism in the related species T. equestre.ConclusionsThese newly developed markers will aid research into the genetic diversity and population structure of T. matsutake. They can also be used in other species of Tricholoma.

Antibacterial Alkaloids and Polyketide Derivatives from the Deep Sea-Derived Fungus Penicillium cyclopium SD-413.

Project description:Nine secondary metabolites (1-9), including two new polyketide derivatives 9-dehydroxysargassopenilline A (4) and 1,2-didehydropeaurantiogriseol E (5), along with seven known related secondary metabolites (1-3 and 6-9), were isolated and identified from the deep sea-derived fungus Penicillium cyclopium SD-413. Their structures were elucidated on the basis of 1D/2D NMR spectroscopic and mass spectrometric analysis and the absolute configurations were determined by the combination of NOESY correlations and time-dependent density functional (TDDFT) ECD calculations. Compounds 1-9 inhibited some pathogenic bacteria including Escherichia coli, E. ictaluri, Edwardsiella tarda, Micrococcus luteus, Vibrio anguillarum, and V. harveyi, with MIC (minimum inhibitory concentration) values ranging from 4 to 32 μg/mL.

Nonproteinogenic amino acid building blocks for nonribosomal peptide and hybrid polyketide scaffolds.

Project description:Freestanding nonproteinogenic amino acids have long been recognized for their antimetabolite properties and tendency to be uncovered to reactive functionalities by the catalytic action of target enzymes. By installing them regiospecifically into biogenic peptides and proteins, it may be possible to usher a new era at the interface between small molecule and large molecule medicinal chemistry. Site-selective protein functionalization offers uniquely attractive strategies for posttranslational modification of proteins. Last, but not least, many of the amino acids not selected by nature for protein incorporation offer rich architectural possibilities in the context of ribosomally derived polypeptides. This Review summarizes the biosynthetic routes to and metabolic logic for the major classes of the noncanonical amino acid building blocks that end up in both nonribosomal peptide frameworks and in hybrid nonribosomal peptide-polyketide scaffolds.

Three new fusidic acid derivatives and their antibacterial activity.

Project description:Two steroid acids, cephalosporin P1 and isocephalosporin P1, were isolated from Hapsidospora irregularis FERM BP-2511. These compounds are structurally related to fusidic acid. Their NMR data were completely assigned on the basis of the 2D NMR spectra. Incubation of these two compounds with Microbacterium oxydans CGMCC 1788 in Luria-Bertani broth yielded the same set of three new 3-dehydrogenated products, 3-keto-isocephalosporin P1, 3-keto-cephalosporin P1 and 6-deacetyl-3-keto-cephalosporin P1. The final pH of the bacterial culture was 9.0. Incubation of 3-keto-isocephalosporin P1 or 3-keto-cephalosporin P1 in Tris-HCl buffer (pH 9.0) revealed that these two compounds can convert to each other by shifting the acetyl group between C-6 and C-7. The acetyl group at C-6 or C-7 can also be removed by hydrolysis to yield the minor product 6-deacetyl-3-keto-cephalosporin P1. These fusidic acid derivatives were tested for the antibacterial activity against the Gram-positive pathogen Staphylococcus aureus. 3-Keto-cephalosporin P1 showed the highest activity among the five compounds, with a minimal inhibition concentration (MIC) of 4 μg/mL, which is more potent than the substrate cephalosporin P1. Both cephalosporin P1 and 3-keto-cephalosporin P1 were active against methicillin-resistant S. aureus, with the same MIC of 8 μg/mL.

Unprecedented Mushroom Polyketide Synthases Produce the Universal Anthraquinone Precursor.

Project description:(Pre-)anthraquinones are widely distributed natural compounds and occur in plants, fungi, microorganisms, and animals, with atrochrysone (1) as the key biosynthetic precursor. Chemical analyses established mushrooms of the genus Cortinarius-the webcaps-as producers of atrochrysone-derived octaketide pigments. However, more recent genomic data did not provide any evidence for known atrochrysone carboxylic acid (4) synthases nor any other polyketide synthase (PKS) producing oligocyclic metabolites. Here, we describe an unprecedented class of non-reducing (NR-)PKS. In vitro assays with recombinant enzyme in combination with in vivo product formation in the heterologous host Aspergillus niger established CoPKS1 and CoPKS4 of C. odorifer as members of a new class of atrochrysone carboxylic acid synthases. CoPKS4 catalyzed both hepta- and octaketide synthesis and yielded 6-hydroxymusizin (6), along with 4. These first mushroom PKSs for oligocyclic products illustrate how the biosynthesis of bioactive natural metabolites evolved independently in various groups of life.
