Abstract
A new hopane type pentacyclic triterpenoid, 2-hydroxydiplopterol (1) has been isolated from the metabolites produced by the halotolerant fungal strain Aspergillus variecolor B-17. The structure of 1 was determined by spectroscopic methods and single crystal X-Ray diffraction analysis. 2-Hydroxydiplopterol (1) exhibited cytotoxicity against K562 cells with an IC50 value of 22 µM.
