Bioactive metabolites from the endophytic fungus Ampelomyces sp. isolated from the medicinal plant Urospermum picroides

Study of an endophytic fungus from Aquilaria malaccensis Lamk

“…The compound I showed UV absorbance at 262, 274 and 415 nm. The UV absorption fitted very well with reported values (264, 274 and 416 nm) of anthraquinone isolated from other sources (Aly et al, 2008;Debbab et al, 2009). From J H NMR and UV absorbance, the structure of I was confirmed as 1,7-dihydroxy-3-methoxyanthraquinone (Figure 1).…”

“…One sharp signal at 3.9 ppm was assigned for oxygenated methyl proton. The chemical shift at 12.11 ppm was due to the chelation of H-bonding of hydroxyl group and carbonyl -oxygen of aromatic system (Aly et al, 2008). The 1 H NMR data of I was similar to macrosporin, a substituted anthraquinone, reported from an endophytic fungus of Ampelomyces sp.…”

A New Isofuranonaphthalenone and Benzopyrans from the Endophytic Fungus Nodulisporium sp. A4 from Aquilaria sinensis

“…Small coupling constants (2.2 and 4.9 Hz) exhibited by HÀC(4) revealed that HÀC(4) was in an equatorial orientation. The large coupling constant 11.2 Hz observed for H ax ÀC(3) and HÀC(2) suggested the axial orientation for HÀC (2), which is in agreement with the literature reports that, in benzopyrans, an equatorial orientation is preferred for the substituent at C(2) [15 -17]. However, the absolute configuration of 2 remains unknown.…”

Isolation and Characterization of Antibacterial Compound from a Mangrove-Endophytic Fungus, Penicillium chrysogenum MTCC 5108

“…More than 200 species of endophytic fungi have been isolated and identified from mangrove plants and several reports on the isolation of antibiotic compounds from endophytic fungi have been reported. To mention a few griseofulvin, [7], chaetomugilin A and D [8], cytosporone B and C [9], 3-O-methylalaternin and altersolanol A [10], phomoenamide [11], phomodione [12], ambuic acid [13], isopestacin [14], munumbicin A, B, C, and D [15], pestalachlorides A and B, [16], brefeldin A [17], coronamycin, [18], pumilacidin [19], cytochalasin D [20], polyketide citrinin [21,22], fumigaclavine C, fumitremorgin C, physcion [23], and several others.…”
