Title: Deconins A-E: Cuparenic and Mevalonic or Propionic Acid Conjugates from the Basidiomycete Deconica sp. 471.

Abstract: Bioassay-guided fractionation of antibacterial extracts from cultures of a basidiomycete from Northern Thailand, which represents a new species of the genus Deconica, yielded the terpenoid deconin A (1), whose structure was elucidated by spectral methods (NMR, HRMS) as a cuparenic/mevalonic acid conjugate. The absolute configuration of 1 was determined after saponification and comparison of specific rotations of the resulting cuparenic acid and mevalonolactone with authentic standards and literature data. Six minor congeners (2-7) were isolated and identified, and their antimicrobial and cytotoxic effects are reported. Compounds 1-4 are the first natural products featuring an unmodified mevalonic acid residue as a building block.
