Antimicrobial Azaphilones from the FungusHypoxylon multiforme

Planta Medica, 2005
Four new azaphilones named multiformins A - D together with a known compound 4 : 5:4':5'-tetrahydroxy-1 : 1'-binaphthyl were isolated from the methanolic stromatal extract of the xylariaceous ascomycete Hypoxylon multiforme. Their absolute structures were characterised by 2D-NMR, UV, IR, mass and CD spectroscopy.

Fungal Azaphilone Pigments as Promising Natural Colorants

Микробиология, 2023
Abstract—Microscopic fungi form and excrete numerous and diverse secondary metabolites, including pigments of various colors, which may be used as an alternative to chemical and plant colorants used in industry. Azaphilone compounds, first discovered in fungi of the genus Monascus, are among the promising classes of fungal pigments. The review analyzes

Cytotoxic azaphilone alkaloids from Chaetomium globosum TY1

Bioorganic & Medicinal Chemistry Letters, 2013
Three novel azaphilone alkaloids, namely chaetomugilides A-C (1-3), together with three related compounds (4-6) were isolated from the methanol extract of Chaetomium globosum TY1, an endophytic fungus isolated from Ginkgo biloba. Their structures were elucidated on the basis of extensive 1D and 2D NMR as well as HRESI-MS spectroscopic data analysis ...

Cytotoxic and Antimalarial Azaphilones from Chaetomium longirostre

Journal of Natural Products, 2011
Four new azaphilones named longirostrerones A-D (1-4) and three known sterols, ergosteryl palmitate, ergosterol, and ergosterol peroxide, have been isolated from ethyl acetate extract of the fungus Chaetomium longirostre. These structures were determined by 1D and 2D NMR, IR, UV, MS, and CD spectroscopy.

Phomoeuphorbins A–D, azaphilones from the fungus Phomopsis euphorbiae

Phytochemistry, 2008
Four azaphilones, named phomoeuphorbins A-D (1-4) were isolated from cultures of Phomopsis euphorbiae, an endophytic fungus isolated from Trewia nudiflora. Structures of 1-4 were established on the basis of spectroscopic analyses, including application of 2D NMR spectroscopic techniques. Phomoeuphorbins A and C exhibited very weak inhibitory activities

Hypoxia-Protective Azaphilone Adducts from Peyronellaea glomerata

Journal of Natural Products, 2018
Peyronellones A and B (1 and 2), a pair of rare tetracyclic caged adducts of azaphilone with pyruvic acid, along with four new analogues (3-6), were isolated from solid cultures of the endophytic fungus Peyronellaea glomerata. Their structures were elucidated through spectroscopic analysis, and their absolute configurations were unambiguously ...

Quantum chemical investigation of electronic transitions of mitorubrin azaphilones

Journal of Computational Chemistry
AbstractFungal azaphilones are a broad class of naturally‐occurring pigments with diverse applications. Among the azaphilone pigments, mitorubrins are well recognized for their antiviral, antibacterial, antifungal, antiprotozoal, antidiabetic, and antiaging activities in addition to their well‐known yellow‐orange color.
