  Ring D modifications of ellipticine. Part 2. Chlorination of ellipticine via its N-oxide and synthesis and selective acetylation of 5,6,11-trimethyl-5H-benzo[b]carbazole.

  摘要：

  The N-oxide of ellipticine can be used for the introduction of a chlorine atom at carbon-3 of the ellipticine nucleus. According to modelstudies with 5,8-dimethylisoquinoline-N-oxide the reaction is guided both by steric hindrance and by nitrogen-6 of the ellipticine system. Attempted nucleophilic substitution reactions of 3-chloro-ellipticines failed. The high cytostatic activity observed for 9-acetylellipticine stimulated us to prepare the corresponding deaza analogue. This compound was synthesized in 2 steps starting from 1-methylindole. Regioselective acetylation at C-2 was accomplished using acetic anhydride and ZnCl2 as a catalyst. Under a variety of other conditions the 2,9-diacetylproduct was formed and no 9-monoacetylated compound could be isolated. Just as the parent compound, the acetylated deazaellipticines showed only very low cytostatic activity.

  The present invention provides a computer-assisted method of generating a protonophore requiring the use of a computer including a processor. The method includes: designing the protonophore, calculating, using the processor, an estimated protonophoric activity; producing the protonophore if the estimated protonophoric activity corresponds to an U 50 of about 20 μM or less; and determining the uncoupling activity of the protonophore. The present invention also provides novel protonophores that meet the above requirement and their methods of use.
