Gr. Pettit et al., ISOLATION AND STRUCTURE OF THE SYMMETRICAL DISTEROIDAL ALKALOIDS CEPHALOSTATIN-12 AND CEPHALOSTATIN-13, Bioorganic & medicinal chemistry letters, 4(12), 1994, pp. 1507-1512
Re-examination of a Western Indian Ocean worm Cephalodiscus gilchristi
has led to discovery of cephalostatins 12 and 13. Cephalostatin 12 (2
) proved to be the first example of a symmetrical disteroidal alkaloid
. Both new cephalostatins significantly inhibited growth of animal and
human cancer cell lines.
