New Meroterpenoid Derivatives from the Pomegranate-Derived Endophytic Fungus <i>Talaromyces purpureogenus</i>
In this study, we report the isolation of two new meroterpenoids, miniolutelide D (<b>1</b>) and miniolutelide E (13-<i>epi</i>-miniolutelide C) (<b>2</b>), along with two meroterpenoidal analogues (<b>3</b> and <b>4</b>) and two phenolic c...

description | In this study, we report the isolation of two new meroterpenoids, miniolutelide D (<b>1</b>) and miniolutelide E (13-<i>epi</i>-miniolutelide C) (<b>2</b>), along with two meroterpenoidal analogues (<b>3</b> and <b>4</b>) and two phenolic compounds (<b>5</b> and <b>6</b>) from the endophytic fungus <i>Talaromyces purpureogenus</i> derived from <i>Punica granatum</i> fruits. Their structures were elucidated using extensive MS, 1D, and 2D NMR spectroscopic analyses as well as by comparing with data in the literature. The absolute configurations of <b>1</b> and <b>2</b> were determined using TDDFT-ECD calculations. Antimicrobial activity was evaluated. Compound <b>5</b> displayed significant activity against methicillin-resistant <i>Staphylococcus aureus</i> strain ATCC 700699 and moderate activity against <i>S. aureus</i> strain ATCC 29213. |
