trails-d-Tocotrienoloic acidThe MCFP is a unique study area for our search for
medicinal agents from tropical plants. We continue to
discover new biological activity and interesting chemi-
cal structures. Our future research efforts will include
other plant families known to contain medicinally
important substances (e.g., Euphorbiaceae, Rutaceae).
We will also screen for antiviral activity and peptide
receptor blocking activity.Acknowledgments This work would not be possible
without our collaborators, most notably Bob Lawton
and Debbie Moriarity from the Department of Biological
Sciences, the University of Alabama in Huntsville. The
efforts of William Haber with plant identification, Bob
Bates (University of Arizona) with structure determi-
nation, and numerous student researchers are gratefully
acknowledged. I am indebted to the Monteverde Cloud
Forest Preserve and the Tropical Science Center for
granting permission to collect leaves. I thank the Na-
tional Institutes of Health and the University of Alabama
in Huntsville for financial support for our research.Literature Cited
