Abstract

10-Bromovindoline and its 14,15-dihydro- and 14,15-cyclopropano derivatives were coupled in the position 16 with (L)- and (D)-tryptophan methyl esters. The tryptophan derivatives of vindoline were synthesized starting from the 16-carboxylic acid hydrazides via the corresponding azides which were allowed to react with the amino acid esters. The new compounds showed antitumor activity against human leukemia (HL-60) cells in vitro.
