From an endophytic fungus, a close relative of Talaromyces sp., found in association with Cedrus deodara, four compounds including two new ones (2 and 4) were isolated and characterized. The structures of two compounds (1 and 4) were confirmed by X-ray crystallography. The compounds displayed a range of cytotoxicities against human cancer cell lines (HCT-116, A-549, HEP-1, THP-1, and PC-3). All the compounds were found to induce apoptosis in HL-60 cells, as evidenced by fluorescence and scanning electron microscopy studies. Also, the compounds caused significant microtubule inhibition in HL-60 cells.

The growing threat of antimicrobial resistance (AMR) has underlined the need for a sustained supply of novel antimicrobial agents. Endophyte microorganism that reside within plant tissues as symbionts have been the source of potential antimicrobial substances. However, many novel and potent antimicrobials are yet to be discovered from these endophytes.

Three novel compounds, including an aromatic amino acid, dimorine A (1), a suncheonoside derivative, dimoroside A (2), and a phenylpropanoid glycoside, dimoroside B (3), together with four known compounds (4-7) were separated from Umbelopsis dimorpha VDG10, the predominant endophytic fungus found in the roots of Vaccinium dunalianum Wight (Ericaceae). Their structures were elucidated by spectroscopic methods, and the ECD spectrum confirmed the absolute configuration of 3. In addition, the antifungal activities of novel compounds against five phytopathogenic fungi were evaluated.
