    Abstract Chemical exploration of the total extract derived from Epicoccum nigrum Ann-B-2, an endophyte associated with Annona squamosa fruits, afforded two new metabolites, epicoccofuran A (1) and flavimycin C (2), along with four known compounds namely, epicocconigrone A (3), epicoccolide B (4), epicoccone (5) and 4,5,6-trihydroxy-7-methyl-1,3-dihydroisobenzofuran (6). Structures of the isolated compounds were elucidated using extensive 1D and 2D NMR along with HR-ESI-MS. Flavimycin C (2) was isolated as an epimeric mixture of its two diastereomers 2a and 2b. The new compounds 1 and 2 displayed moderate activity against B. subtilis, whereas compounds (2, 3, 5, and 6) showed significant antiproliferative effects against a panel of seven different cancer cell lines with IC

    Abstract Chromatographic refining of the EtOAc extract of a solid rice culture of the hypersaline lake-derived fungus Penicillium simplicissimum strain WSH17 afforded a new linear antibacterial peptide quinoisobutyride A (1) along with three known metabolites (2-4). The chemical structure of 1 was unambiguously determined based on extensive 1D and 2D NMR spectroscopic analyses together with HRESIMS. In addition, Marfey’s derivatization method along with biogenetic considerations were used to determine the absolute configuration of its amino acids’ entities. Interestingly, in this study we distinguished a new unusual heterocyclic amino acid which is comprised as a unit of compound 1. Among the isolated compounds, only 1 revealed a promising antibacterial activity against Staphylococcus aureus (ATCC700699) with a MIC value of 2.72 μM (2.0 μg/mL). Moreover, citrinamide A (3) was the only isolated compound that showed a cytotoxic activity against human epithelial colorectal adenocarcinoma (Caco-2) cell line with an IC50 value of 12.76 μM (5.5 μg/mL).

    Abstract Chromatographic analysis of a crude ethyl acetate (EtOAc) extract derived from a solid rice culture incubated at 40°C to mimic the natural ecological niche of the extremophilic fungus Botryotrichum piluliferum strain WESH19 yielded a new natural butenolide compound (1) together with three known metabolites (2–4). Chemical structures of the isolated metabolites were confirmed by HR-ESI-MS along with 1D and 2D NMR spectroscopic analyses. Compounds 1–3 revealed pronounced antimicrobial activities against Staphylococcus aureus (ATCC 700699), Enterococcus faecalis (ATCC 29212), and Enterococcus faecium (ATCC 35667), while their antifungal activities were assessed against the extremophilic fungus Penicillium simplicissimum strain WSH17 (GenBank Acc. No. MN055685). This study adds another example of how extreme environmental conditions may influence secondary metabolism of the inhabiting fungi.
