Main Methods:

• Phytochemical investigation of Acronychia pedunculata leaves and twigs.
• Spectroscopic elucidation of the structures of isolated compounds.
• In vitro assays to determine inhibitory activity against mammalian DNA polymerases.
• Cell-based assays to evaluate human cancer cell growth inhibition.

Main Results:

• Isolation and identification of three new acetophenone monomers (1-3).
• Characterization of additional compounds including a new acetophenone (4), acronyculatin E (5), a mixture of β-sitosterol and stigmasterol, and sesamin.
• Demonstration of inhibitory activity of isolated acetophenone derivatives against mammalian DNA polymerases.
• Assessment of the inhibitory effects of these compounds on human cancer cell proliferation.

Conclusions:

• The phytochemical analysis of Acronychia pedunculata yielded novel acetophenone derivatives.
