Simple method for preparing ellipticine or substituted ellipticine
The invention relates to a synthesis process for preparing ellipticine. Ellipticine is obtained through six steps of reaction and three steps of crystallization separation, the target product total yield is high, column chromatography separation is not needed for an intermediate product and the target product, and the method is particularly suitable for large-scale preparation.

Modifications to the Vilsmeier-Haack formylation of 1,4-dimethylcarbazole and its application to the synthesis of ellipticines
Figure represented. An improved method for the preparation of 3-formyl-1,4-dimethylcarbazole, a key intermediate in the synthesis of ellipticine, is presented. Conditions of the Vilsmeier-Haack reaction have been modified to facilitate the production of 3-formyl-1,4-dimethylcarbazole as a major product leading to an overall improvement in yield of ellipticine from 3% to 14%. This approach was also applied to the synthesis of 6-methylellipticine and 9-methoxyellipticine.

Ellipticines and 9-acridinylamines as inhibitors of d-alanine:d-alanine ligase
d-Alanine:d-alanine ligase (Ddl), an intracellular bacterial enzyme essential for cell wall biosynthesis, is an attractive target for development of novel antimicrobial drugs. This study focused on an extensive evaluation of two families of Ddl inhibitors encountered in our previous research. New members of both families were obtained through similarity search and synthesis. Ellipticines and 9-acridinylamines were both found to possess inhibitory activity against Ddl from Escherichia coli and antimicrobial activity against E. coli and Staphylococcus aureus. Ellipticines with a quaternary methylpyridinium moiety were the most potent among all studied compounds, with MIC values as low as 2 mg/L in strains with intact efflux mechanisms. Antimicrobial activity of the studied compounds was connected to membrane damage, making their development as antibacterial drug candidates unlikely unless analogues devoid of this nonspecific effect can be discovered.
