摘要
A series of four novel hydrazine-modified diamine conjugates （7a-b, 8a-b） were synthesized and evaluated for cytotoxicity against Melanoma B 16, α-difluoromethylornithine （DFMO）-treated B 16, spermidine （SPD）-treated B 16, Mouse leukemia L 1210 and Hela cell lines. Both the DFMO-B 16 and SPD-B 16 experiments indicated that conjugates 7a-b and 8a-b could recognize the polyamine transporter （PAT） and enter the cells in part or in whole via PAT, although they were not as efficient as the reference, 9- anthracenemethyl homospermidine （1）. 2007 Chao Jie Wang.
