Several ochrolifuanines, indole alkaloid analogs of emetine and tubulosine have been synthesized by PICTET-Spengler condensation between dihydrocorynantheal and various tryptamines. The study of the biological properties of these molecules (i.e.: determination of the cytotoxicity using the Allium test, effect on the growth of normal chick embryo fibroblasts, the transformation of these cells by Rous sarcoma virus and the effect on P 388 leukemia of mice) has established the expected cytotoxicity but has shown a lack of specificity towards tumor cells. The results are discussed in order to orient further synthesis to prepare more selective derivatives.
