Synthesis and antibacterial activity of novel arylbis(indol-3-yl)methane derivatives

A series of new compounds—arylbis(indol-3-yl)methylium derivatives—were synthesized and their antimicrobial activity was evaluated. All the compounds turned out to be highly active, with MIC depending on their structure and the length of N -alkyl residues. The parent triarylmethane compounds possess weaker activity.
