Abstract The synthesis of the esters 6d-8d, 9 c and 10 c is described. These compounds are closely structurally related to the irritant and tumorpromoting 12-O-tetradecanoylphorbol-13-acetate (TPA, 2 a) and to phorbol-12,13-didecanoate (PDD, 2 c) except that they possess no cyclopropane ring. Biological tests show that opening or complete removal of the cyclopropane ring leads to nearly total loss of irritant or tumorpromoting (tested in the case of 9 c and 10 c) activity.

Tubulin Carboxypeptidase

Cyclic ether derivatives of parthenolide were synthesized by using two cyclization strategies, relying on 2-(silyloxy) allylboration. Characterization for tubulin carboxypeptidase inhibition generated new insights into structure–activity relationships.
