Abstract

This research proposal aims the synthesis of tarchonanthuslactone, a natural product isolated from the leaves of the tree Tarchonanthus trilobus, whose biological activity has not yet been explored. The sructure of tarchonanthuslactone may be envisioned as a hybrid structure of cafeic acid, a natural product isolated from the fruit of Xanthium strumarium which has inhibitory activity of protein tyrosine phosphatase 1B (PTP1B), and other natural and synthetic products with anticancer activity containing as pharmacophore an a,b-unsaturated lactone. This led us to consider that tarchonanthuslactone may have action on phosphatase PTP1B, cancer and diabetes. Initially three analogs are proposed to be tested together with the natural and caffeic acid lactone. If the initial biological results justify, new analogues will be planned and prepared in order to follow the trials and biological studies of structure-activity.(AU)
