  Potent Antiglioblastoma Agents by Hybridizing the Onium-Alkyloxy-Stilbene Based Structures of an α7-nAChR, α9-nAChR Antagonist and of a Pro-Oxidant Mitocan

  摘要：

  Adenocarcinoma and glioblastoma cell lines express alpha 7- and alpha 9 alpha 10-containing nicotinic acetylcholine receptors (nAChRs), whose activation promotes tumor cell growth. On these cells, the triethylammoniumethyl ether of 4-stilbenol MG624, a known selective antagonist of alpha 7 and alpha 9 alpha 10 nAChRs, has antiproliferative activity. The structural analogy of MG624 with the mitocan RDM-4'BTPI, triphenylphosphoniumbutyl ether of pterostilbene, suggested us that molecular hybridization among their three substructures (stilbenoxy residue, alkylene linker, and terminal onium) and elongation of the alkylene linker might result in novel antitumor agents with higher potency and selectivity. We found that lengthening the ethylene bridge in the triethylammonium derivatives results in more potent and selective toxicity toward adenocarcinoma and glioblastoma cells, which was paralleled by increased alpha 7 and alpha 9 alpha 10 nAChR antagonism and improved ability of reducing mitochondrial ATP production. Elongation of the alkylene linker was advantageous also for the triphenylphosphonium derivatives resulting in a generalized enhancement of antitumor activity, associated with increased mitotoxicity.

  Twelve new fluorescent (E)-2-stilbenyloxyalkylthiouracils and 6-methyluracils 5a-51 were prepared. EI induced mass spectral fragmentation of these compounds was investigated. Fragmentation pathways are proposed on the basis of accurate mass and metastable transition measurements. Correlation between the intensities of the M+ and the selected fragment ions of these compounds is discussed. The data obtained

  The synthesis of twenty-one new (E)-4-[piperidino-(4'-methylpiperidino-, morpholino-)N-alkoxy] stilbenes is reported. The compounds were tested for antimicrobial activities against Gram-negative, Gram-positive bacteria, and fungi. In particular, compounds 3b, 3c, 3f, 3g, 3h, 3k, 3I showed good antibacterial activity against Staphylococcus aureus and 3h, 3k, 3m, 3n also against Bacillus subtilis, as well as 3h, 3n also against Streptococcus faecalis.
