New derivatives of spicamycin modified at the fatty acid moieties of the molecule were synthesized and their structure-activity relationships were examined. The antitumor activity was greatly influenced by modification of the fatty acid moieties to tetradecadienoyl or dodecadienoyl analogues exhibiting better antitumor activity against COL-1 human colon cancer xenograft than SPM VIII.

Abstract Two synthetic schemes were designed giving access to tritium labelled potential precursors of Drosophila pheromones. An intermediate in the first scheme allowed the preparation of [3H]-labelled vaccenyl acetate.
