Polyketides with antimicrobial activity from the solid culture of an endolichenic fungus Ulocladium sp.[Pubmed:22061662]
Fitoterapia. 2012 Jan;83(1):209-14.
Two new polyketides, 7-hydroxy-3, 5-dimethyl-isochromen-1-one (1) and 6-hydroxy-8-methoxy-3a-methyl-3a,9b-dihydro-3H-furo[3,2-c]isochromene-2,5-dione (2), along with eleven known compounds, 5'-methoxy-6-methyl-biphenyl-3,4,3'-triol (3), 7-hydroxy-3-(2-hydroxy-propyl)-5-methyl-isochromen-1-one (4), rubralactone (5), isoAltenuene (6), Altenuene (7), dihydroAltenuenes A (8), altenusin (9), alterlactone (10), 6-O-methylnorlichexanthone (11), norlichexanthone (12), and griseoxanthone C (13) were isolated from the culture of the endolichenic fungus Ulocladium sp. Compound 2 was obtained as a racemate with an unprecedented chemical skeleton. The NMR data assignments for 3 and 4 were achieved for the first time. Compounds 1-13 were screened for their antimicrobial and radical scavenging activities. Compound 1 showed some antifungal activity against Candida albicans SC 5314 with IC(50) of 97.93 +/- 1.12 muM. Compounds 11-13 showed strong activity against Bacillus subtilis with IC(50) in the range of 1-5 muM. Compound 12 significantly inhibited the growth of methicillin-resistant Staphylococcus aureus with IC(50) of 20.95 +/- 1.56 muM. Compounds 9 and 10 showed strong radical scavenging activity in comparison with vitamin C. The plausible biosynthetic pathways for compounds 1, 2, and 4-8 were discussed.
Alternaria toxins in South African sunflower seeds: cooperative study.[Pubmed:28755328]
Mycotoxin Res. 2017 Nov;33(4):309-321.
Sunflower seed samples (N = 80) from different sunflower cultivars originating from different localities in South Africa were analyzed for 15 toxins produced by fungi of the genus Alternaria by means of a simple one-step extraction dilute-and-shoot HPLC-MS/MS approach. References for valine-tenuazonic acid (Val-TeA), altenusin (ALTS), and altenuisol (ALTSOH) were isolated from fungal culture extracts and spectroscopically characterized. Additionally, valine-tenuazonic acid was tested regarding its cytotoxicity in comparison with tenuazonic acid (TeA) and showed less activity on HT-29 cells. Furthermore, alternariol monomethyl ether-3-O-ss-D-glucoside (AME-3G) was produced by fermentation of alternariol monomethyl ether (AME) with the fungus Rhizopus oryzae. The seed samples were analyzed both with and without hulls. The method covers the AAL toxins TA1 and TA2, Altenuene (ALT) and iso-Altenuene (iso-ALT), altenuisol, altenusin, altertoxin I (ATX-I) and altertoxin II (ATX-II), alternariol (AOH) and alternariol monomethyl ether, alternariol monomethyl ether-3-O-ss-D-glucoside, tenuazonic acid, allo-tenuazonic acid (allo-TeA) and valine-tenuazonic acid, and tentoxin (TEN). More than 80% of the samples were positive for one or more analytes above the respective limit of detection (0.2-23 mug/kg). Alternariol, its monomethyl ether, tentoxin, tenuazonic acid, altenuisol, and valine-tenuazonic acid were found in quantifiable amounts. The highest prevalences were found for tentoxin (73% positive, mean content 13.2 mug/kg, maximum level 130 +/- 0.9 mug/kg) followed by tenuazonic acid (51% positive, mean content 630 mug/kg, maximum level 6300 +/- 560 mug/kg). The obtained data were further analyzed statistically to identify quantitative or qualitative relationships between the levels of Alternaria toxin in the samples.
[A new sesquiterpenoid from fungus Colletotrichum sp. and its cytotoxicity].[Pubmed:23984524]
Yao Xue Xue Bao. 2013 Jun;48(6):891-5.
A novel sesquiterpenoid (1) and three known compounds identified as isoAltenuene (2), Altenuene (3), and alternariol 4, 10-O-dimethyl ether (4), were isolated in our investigation of the cytotoxic constituents from solid cultures of the endophytic fungus Colletotrichum sp. The structures of these compounds were elucidated through spectroscopic data analysis. All compounds exhibited cytotoxic activity against lung cancer cell line A549, breast cancer cell line MDA-MB-231 and pancreatic cancer cell line PANC-1. Compound 4 could induce the PANC-1 cells inflation or death, but couldn't induce apoptosis at the IC50 of 60.2 microg x mL(-1).
A new alternariol glucoside from fungus Alternaria alternate cib-137.[Pubmed:25520187]
Nat Prod Res. 2015;29(9):848-52.
A new secondary metabolite, 2-O-methylalternariol 4-O-beta-[4-methoxyl-glucopyranoside] (1), together with four known compounds alternariol methyl ether (2), Altenuene (3), isoAltenuene (4) and 2-(2'S-hydroxypropyl)-5-methyl-7-hydroxychromone (5), was isolated from the fungus Alternaria alternate cib-137. Its structure was elucidated on the basis of spectroscopic data. Compounds 3 and 4 demonstrated moderate activity against Staphylococcus aureus.
