Abstract

We designed three polyamine analogues, 1,14-diamino-N5-methyl-5,10- diazatetradecane (5me-4-4-4), 1,14-diamino-N5,N5-dimethyl-5,10- diazatetradecane (Q-Amm-4-4-4), and 1,14-bis-(ethylamino)-N5,N5-dimethyl- 5,10-diazatetradecane (BE-Q-Amm-4-4-4), on the basis of computer modeling and physical-chemical studies of polyamine-DNA interactions. These analogues differ from natural polyamines and from one another in the charge distribution on their aliphatic backbone. We found that 10 μM 5me-4-4-4 did not inhibit growth and was not cytotoxic to the human brain tumor cell lines SF-767 and SF-126. The same concentrations of Q-Amm-4-4-4 and BE-Q-Amm-4-4-4 inhibited cell growth and killed more than 90% of each cell type on day 7 of the experiment. BE-Q-Amm-4-4-4 was slightly more toxic than Q-Amm-4-4-4 in both cell lines. All three agents either decreased or completely depleted intracellular putrescine and spermidine. Q-Amm-4-4-4 and BE-Q-Amm-4-4-4 each also lowered spermine. The fact that 5me-4-4-4 was nontoxic but that Q-Amm- 4-4-4 was cytotoxic and inhibited growth suggests that the charge distribution along the surface of the aliphatic backbone of polyamines is important in determining growth inhibition and cytotoxicity.
