Megjegyzések:Two new cryptic 3,4-dihydronaphthalen-(2H)-1-one (1-tetralone) derivatives, aspvanicin A (1) and its epimer aspvanicin B (2), as well as several known cryptic metabolites (3-8), were obtained from the ethyl acetate extract of the co-culture of the endophytic fungus Aspergillus versicolor KU258497 with the bacterium Bacillus subtilis 168 trpC2 on solid rice medium. When A. versicolor was cultured axenically in liquid Wickerham medium supplemented with 3.5% DMSO, an additional three known secondary metabolites (9?11) were isolated that were lacking when the fungus was fermented on rice medium. The structures of the new compounds were elucidated using one- and two-dimensional NMR spectroscopy as well as HRESIMS. The relative and absolute configurations of 1 and 2 were determined by the combination of NMR and electronic circular dichroism (ECD) analysis aided by DFT conformational analysis and TDDFT-ECD calculations. The ECD calculations revealed that although the sign of the blue-shifted overlapping n-?* ECD transition follows the helicity rule of cyclic aryl ketones, the calculation of low-energy conformers and ECD spectra was necessary to determine the stereochemistry. All metabolites were assessed for their antibacterial and cytotoxic activities; one of the new diastereomers, compound 2, showed moderate cytotoxic activity against the mouse lymphoma cell line L5178Y.

Megjegyzések:A new cyclic pentapeptide, cotteslosin C (1), a new aflaquinolone, 22-epi-aflaquinolone B (3), and two new anthraquinones (9 and 10), along with thirty known compounds (2, 4???8, 11???34) were isolated from a co-culture of the sponge-associated fungus Aspergillus versicolor with Bacillus subtilis. The new metabolites were only detected in the co-culture extract, but not when the fungus was grown under axenic conditions. Furthermore, the co-culture extract exhibited an enhanced accumulation of the known constituents versicolorin B (14), averufin (16), and sterigmatocyctin (19) by factors of 1.5, 2.0, and 4.7, respectively, compared to the axenic fungal culture. The structures of the isolated compounds were elucidated on the basis of 1D and 2D NMR spectra and mass spectrometry as well as by comparison with literature data. The absolute configuration of compounds 3, 9, and 10 was determined by ECD (electronic circular dichroism) analysis aided by TDDFT-ECD (time-dependent density functional theory electronic circular dichroism) calculations. Compounds 15, 18???21, and 26 exhibited strong to moderate cytotoxic activity against the mouse lymphoma cell line L5178Y, with IC50 values ranging from 2.0 to 21.2??M, while compounds 14, 16, 31, 32, and 33 displayed moderate inhibitory activities against several gram-positive bacteria, with MIC values ranging from 12.5 to 50??M.

Cím:Inducing secondary metabolite production by the endophytic fungus Chaetomium sp. through fungal-bacterial co-culture and epigenetic modification / Sergi Herve Akone, Attila Mandi, Tibor Kurtan, Rudolf Hartmann, Wenhan Lin, Georgios Daletos, Peter Proksch
Dátum:2016
ISSN:0040-4020
Megjegyzések:Co-culturing the fungal endophyte Chaetomium sp. with the bacterium Bacillus subtilis on solid rice medium resulted in an up to 8.3-fold increase in the accumulation of constitutively present metabolites that included a 1:1 mixture of 3- and 4-hydroxybenzoic acid methyl esters (1 and 2, respectively), and the polyketides acremonisol A (3), SB236050 (4), and SB238569 (5). In addition, seven compounds including isosulochrin (6), protocatechuic acid methyl ester (7), as well as five new natural products (8?12) were detected in the co-cultures, but not in axenic fungal cultures. Treatment of Chaetomium sp. with the epigenetic modifier suberoylanilide hydroxamic acid or 5-azacytidine resulted in an enhanced accumulation of 6, which was likewise detected during co-culture. Compound 5 showed strong cytotoxicity against the mouse lymphoma L5178Y cell line with an IC50 value of 1 mM, as well as weak antibacterial activity against B. subtilis with an MIC value of 53 mM.

Cím:Chaetolines A and B, Pyrano[3,2-f]isoquinoline Alkaloids from Cultivation of Chaetomium sp. in the Presence of Autoclaved Pseudomonas aeruginosa / Elena Ancheeva, Attila Mándi, Sándor B. Király, Tibor Kurtán, Rudolf Hartmann, Sergi H. Akone, Horst Weber, Georgios Daletos, Peter Proksch
Dátum:2018

Megjegyzések:The first members of a new alkaloid class, chaetolines A (1) and B (2), which feature a pyrano[3,2-f ]isoquinoline core structure, were obtained from a crude extract of the fungal endophyte Chaetomium sp. after cultivation in the presence of autoclaved Pseudomonas aeruginosa. The structures of the new compounds, including the absolute configuration of the major stereoisomer, were determined through detailed analysis of HRESIMS, 1D/2D NMR, and calculation of ECD data. The possible biosynthetic origin of the unprecedented scaffold of 1 and 2 is proposed. The current study provides further evidence for mixed fermentation as a powerful tool to induce the accumulation of cryptic fungal natural products even in the absence of viable bacterial cells.

Megjegyzések:The mixed fermentation of the fungal endophyte Chaetomium sp. with an autoclaved culture of the bacterium Pseudomonas aeruginosa on solid rice medium led to an up to 33-fold increase in the accumulation of constitutively present fungal secondary metabolites (3-10), which included four new butenolide derivatives (3-5 and 7). In addition, two further shikimic acid analogues (1 and 2) were obtained from mixed cultures that were neither detected in axenic cultures of the fungus nor of the bacterium. Chaetoisochorismin (1 ) possesses an unusual (3-methoxycarbonylphenyl)pyruvate core structure. The structures of the new compounds were unequivocally elucidated by HRESIMS, one- and two-dimensional NMR analysis as well as by comparison with literature data. The absolute configurations of the structures of the new derivatives 1 and 2 were established by ECD calculations as well as by the modified Mosher's method. Compounds 1-3 and 5-7 were subjected to antimicrobial and cytotoxicity assays but were shown to be inactive.

Cím:Expanding the chemical diversity of an endophytic fungus Bulgaria inquinans, an ascomycete associated with mistletoe, through an OSMAC approach / Ni P. Ariantari, Georgios Daletos, Attila Mándi, Tibor Kurtán, Werner E. G. Müller, Wenhan Lin, Elena Ancheeva, Peter Proksch
Dátum:2019
ISSN:2046-2069 2046-2069
Megjegyzések:An endophytic fungus Bulgaria inquinans (isolate MSp3-1), isolated from mistletoe (Viscum album), was subjected to fermentation on solid Czapek medium. Chromatographic workup of the crude EtOAc extract yielded five new natural products (1?5). Subsequent application of the "One Strain, Many Compounds" (OSMAC) strategy on this strain by the addition of a mixture of salts (MgSO4, NaNO3 and NaCl) to solid Czapek medium induced the accumulation of nine additional new secondary metabolites (6?13, 16), with most of them (8, 10?12) not detectable in cultures lacking the salt mixture. The structures of the new compounds were established on the basis of the 1D/2D NMR and HRESIMS data. The TDDFT-ECD method was applied to determine the absolute configurations of the new compounds 1, 4 and 6 as well as of the previously reported bulgarialactone B (14), for which the absolute configuration was unknown so far. The modified Mosher's method was performed to assign the absolute configurations of 12 and 13. TDDFT-ECD analysis also allowed determining the absolute configuration of (+)-epicocconone, which had an enantiomeric absolute configuration in the tricyclic moiety compared to that of bulgarialactone B (14). All the isolated metabolites were evaluated for their cytotoxic activity. Compound 2 was found to possess strong cytotoxic activity against the murine lymphoma cell line L5178Y with an IC50 value of 1.8 mM, while the remaining metabolites were shown to be inactive.

Megjegyzések:A chemical investigation of the endophyte Penicillium sp. (strain ZO-R1-1), isolated from roots of the medicinal plant Zingiber of f icinale, yielded nine new indole diterpenoids (1-9), together with 13 known congeners (10-22). The structures of the new compounds were elucidated by 1D and 2D NMR analysis in combination with HRESIMS data. The absolute configuration of the new natural products 1, 3, and 7 was determined using the TDDFT-ECD approach and confirmed for 1 by single-crystal X-ray determination through anomalous dispersion. The isolated compounds were tested for cytotoxicity against L5178Y, A2780, J82, and HEK-293 cell lines. Compound 1 was the most active metabolite toward L5178Y cells, with an IC50 value of 3.6 mu M, and an IC50 against A2780 cells of 8.7 mu M. Interestingly, 1 features a new type of indole diterpenoid scaffold with a rare 6/5/6/6/6/6/5 heterocyclic system bearing an aromatic ring C, which is suggested to be important for the cytotoxic activity of this natural product against L5278Y and A2780 cells.

Megjegyzések:The marine-derived fungus Penicillium sp. (strain IO1) isolated from the Mediterranean sponge Ircinia oros yielded a new fusarielin analogue (1) together with the known compounds griseofulvin (4) and dechlorogriseofulvin (5). The structure of 1 was unambiguously elucidated by comprehensive spectroscopic analysis (1D and 2D NMR, and mass spectrometry) as well as by comparison with the literature, while the absolute configuration of 1 was determined on the basis of TDDFT ECD calculations. A further Penicillium sp. (strain IO2) that was isolated from the same sponge I. oros yielded the known compounds dehydrocurvularin (6), curvularin (7), and trichodimerol (8). Co-cultivation of both Penicillium strains (IO1 and IO2) was found to induce the accumulation of the known norlichexanthone (2) and monocerin (3) that were not detected in either of the two axenic fungal controls. Compounds 3 and 6 showed pronounced cytotoxicity against the murine lymphoma (L5178Y) cell line with IC50 values of 8.4 and 4.7 lM, respectively.

Cím:Polyketides and a Dihydroquinolone Alkaloid from a Marine Derived Strain of the Fungus Metarhizium marquandii / Dina H. El-Kashef, Georgios Daletos, Malte Plenker, Rudolf Hartmann, Attila Mándi, Tibor Kurtán, Horst Weber, Wenhan Lin, Elena Ancheeva, Peter Proksch
Dátum:2019
ISSN:0163-3864 1520-6025
Megjegyzések:Three new natural products (1-3), including two butenolide derivatives (1 and 2) and one dihydroquinolone derivative (3), together with nine known natural products were isolated from a marine-derived strain of the fungus Metarhizium marquandii. The structures of the new compounds were unambiguously deduced by spectroscopic means including HRESIMS and 1D/2D NMR spectroscopy, ECD, VCD, OR measurements, and calculations. The absolute configuration of marqualide (1) was determined by a combination of modified Mosher's method with TDDFTECD calculations at different levels, which revealed the importance of intramolecular hydrogen bonding in determining the ECD features. The (3R,4R) absolute configuration of aflaquinolone I (3), determined by OR, ECD, and VCD calculations, was found to be opposite of the (3S,4S) absolute configuration of the related aflaquinolones A-G, suggesting that the fungus M. marquandii produces aflaquinolone I with a different configuration (chiral switching). The absolute configuration of the known natural product terrestric acid hydrate (4) was likewise determined for the first time in this study. TDDFT-ECD calculations allowed determination of the absolute configuration of its chirality center remote from the stereogenic unsaturated ?-lactone chromophore. ECD calculations aided by solvent models revealed the importance of intramolecular hydrogen bond networks in stabilizing conformers and determining relationships between ECD transitions and absolute configurations.

Megjegyzések:Three new flavipin-derived alkaloids, azacoccones F-H (1-3), along with six known compounds (4-9) were isolated from the endophytic fungus Epicoccum nigrum MK214079 associated with leaves of Salix sp. The structures of the new compounds were established by analysis of their 1D/2D nuclear magnetic resonance (NMR) and high-resolution electrospray ionization mass spectroscopy (HRESIMS) data. The absolute configuration of azacoccones F-H (1?3) was determined by comparison of experimental electronic circular dichroism (ECD) data with reported ones and biogenetic considerations. Epicocconigrone A (4), epipyrone A (5), and epicoccolide B (6) exhibited moderate antibacterial activity against Staphylococcus aureus ATCC 29213 with minimal inhibitory concentration (MIC) values ranging from 25 to 50 ?M. Furthermore, epipyrone A (5) and epicoccamide A (7) displayed mild antifungal activity against Ustilago maydis AB33 with MIC values of 1.6 and 1.8 mM, respectively. Epicorazine A (8) showed pronounced cytotoxicity against the L5178Y mouse lymphoma cell line with an IC50 value of 1.3 ?M.

Megjegyzések:The dimeric anthracene derivative torrubiellin B (1) was isolated from the endophytic fungus Acremonium sp. that had been obtained from leaves of the Mangrove plant Sonneratia caseolaris. The absolute configuration of 1 was established as (5'R,10'S,10a'R) for the first time on the basis of its electronic circular dichroism (ECD) spectra aided with TDDFT-ECD calculations. Torrubiellin B (1) exhibited strong anti-tumor activity when tested in vitro against several solid cancer cell lines including cells that are resistant against the widely used cytostatic drug cisplatin. The IC50 values of 1 against cisplatin sensitive and cisplatin resistant cells were in the range of 0.2?2.6 ?M depending on cell line investigated.
