  Conformationally Restricted Analogues of ¹N,¹²N-Bisethylspermine:  Synthesis and Growth Inhibitory Effects on Human Tumor Cell Lines

  摘要：

  Eight analogues of N-1,N-12-bisethylspermine (BES) with restricted conformations were synthesized in the search for new spermine mimetics with cytotoxic activities. By replacing the central butane segment of BES with a 1,2-disubstituted cyclopropane ring, a pair of cis/trans-isomers was obtained that introduced a spatial constraint in the otherwise freely mobile butane chain. An analogous pair of isomers was obtained when the butane segment was replaced with a 1,2-disubstituted cyclobutane ring or with a 2-butene residue. The six new BES analogues thus obtained.(three pairs of cis/trans-isomers) were growth inhibitory at low-micromolar concentrations against four human tumor cell lines (A549, HT-29, U251MG, and DU145) but were less growth inhibitory against two other human tumor cell lines (PC-3 and MCF7). N-1,N-12-Bisethylspermyne, where the central butane segment of BES was replaced by the rigid 2-butyne segment, was devoid of growth inhibitory activity against five of the six human cell lines studied (DU145 being the only exception), a clear indication of the importance of conformational mobility at the N-4,N-9-butane segment of BES for its biological activity. When the butane segment was replaced by a benzene-1,2-dimethyl residue, the resulting BES analogue was devoid of growth inhibitory activity despite its cisoid conformation. The cytotoxicity of the analogues does not seem to be directly related to their uptake by the cells or to their effects on cellular polyamine levels. BES analogues with restricted conformations but which contained the equivalent of a two-carbon unit, rather than the natural four-carbon unit, at the central segment, such as 1,2-diaminocyclopropyl or 1,2-diaminocyclobutyl derivatives, were devoid of growth inhibitory effects at the concentrations studied. The development of conformationally restricted polyamine analogues appears to show promise in the further quest for polyamine-related therapeutic agents with specificity of action.

  Twelve analogues of N-1,N-14-bisethylhomospermine (BE-4-4-4) with restricted conformations were synthesized in the search for cancer chemotherapeutic agents with higher cytotoxic activities and lower systemic toxicities than BE-4-4-4. The central butane segment of BE-4-4-4 was replaced with a 1,2-substituted cyclopropane ring, a 1,2-substituted cyclobutane ring, and a 2-butene residue. In each case, the cis/trans-isomeric pair was synthesized. Cis-monounsaturation(s) was also introduced at the outer butane segment(s) of BE-4-4-4. The two possible cis-dienes and a cis-triene formally derived from the tetraazaeicosane skeleton of BE-4-4-4 were also prepared. Four cultured human prostate cancer cell lines (LnCap, DU145, DuPro, and PC-3) were treated with the new tetramines to examine their effects on cell growth with a MTT assay. One representative cell line (DuPro) was selected to further study the cellular uptake of the novel tetramines, their effects on intracellular polyamine pools, and their cytotoxicity. All tetramines entered the cells, reduced cellular putrescine and spermidine pools while exerting only a small effect on the spermine pool, inhibited cell growth, and killed 2-3 log; of cells after 6 days of treatment at 10 muM. Four new tetramines, the two cyclopropyl isomers, the trans-cyclobutyl isomer, and the (5Z)-tetraazaeicosene, were more cytotoxic than their saturated counterpart (BE-4-4-4). Their cytotoxicity, however, could not be correlated either with their cellular uptake or with their ability to deplete intracellular polyamine pools. We attribute their cytotoxicity to their specific molecular structures. The cytotoxicity was markedly reduced when the central butane segment was deprived of its rotational freedom by replacing it with a double bond. Introduction of a triple bond or a benzene-1,2-dimethyl residue at the central segment of the polyamine chain, led to complete loss of biological activity. The conformationally restricted alicyclic derivatives were not only more cytotoxic than was the freely rotating BE-4-4-4 by several orders of magnitude but also had much lower systemic toxicities than the latter. Thus, we obtained new tetramines with a wider therapeutic window than BE-4-4-4.
