Their structures, including absolute configurations, were elucidated by extensive analysis of spectroscopic data, electronic circular dichroism, Mo2(AcO)4-induced circular dichroism, and comparison with reported data. All of the isolated compounds were tested for their \u03b1-glucosidase inhibitory activity and cytotoxicity. New compounds 4 and 5 exhibited potent \u03b1-glucosidase inhibitory activity with IC50 values of 25.8 and 54.6 \u00b5M, respectively, which were more potent than the positive control (acarbose, IC50 = 703.8 \u00b5M). The good results of the tested bioactivity allowed us to explore \u03b1-glucosidase inhibitors in lasiodiplodins.<\/jats:p>","DOI":"10.3390\/md15020035","type":"journal-article","created":{"date-parts":[[2017,2,15]],"date-time":"2017-02-15T10:09:07Z","timestamp":1487153347000},"page":"35","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":64,"title":["Induction of Diverse Bioactive Secondary Metabolites from the Mangrove Endophytic Fungus Trichoderma sp.
