The present paper reports an easy preparation of imines of N-methyl-1H-indole-3-carboxaldehyde by its condensation with alkyl and aromatic amines in ethanol without using any catalyst or dehydrating agent. The compounds have been screened for their antibacterial, antifungal, crown gall tumor inhibitory, and cytotoxic activities. As a major finding some of the compounds exhibited potential biological activity. The imine containing a 4-chlorophenyl group exhibits potential antitumor activity and brine shrimp lethality against crown gall tumor and brine shrimps, respectively. Furthermore, this imine containing a 4-chlorophenyl group also exhibits significant antifungal activity against Candida albicans fungal strains. The compound containing N-diphenylmethyl group has been observed most active against the Gram-positive bacteria.
