We disclose here the design, synthesis, and biological evaluation of simplified Z- and E-C(2-3) alkynyl phorboxazole C(11-15) acetals (+)-7Z and (+)-7E, wherein the Z-isomer proved to be a potent nanomolar cytotoxic agent. Reevaluation of (+)-C(45-46) E-chloroalkenyl phorboxazole A (6) confirms subnanomolar activity across a broad panel of human cancer cell lines.
