Main Results:

  • A new alkaloid, pipersintenamide (1), was identified.
  • Fourteen known compounds were also isolated and characterized.
  • Pipersintenamide, sintenpyridone, sarmentine, and 1-(3,4-methylenedioxyphenyl)-1E-dodecene demonstrated significant cytotoxicity (<15% cell survival) at 20 microg/ml.
  • These compounds showed activity against multiple cancer cell lines, including leukemia and prostate cancer models.

Conclusions:

  • Piper sintenense is a source of bioactive compounds with cytotoxic properties.
  • Pipersintenamide is a novel alkaloid with promising anti-cancer potential.
  • The identified compounds warrant further investigation as potential leads for anti-cancer drug development.
