| Summary: | Indole-containing compounds are widely distributed in the plant and animal kingdom, and their biological activity and pharmacological properties have prompted research into their chemical properties. This study developed a one-pot methodology for the synthesis of 3-aminoindole derivatives using copper- and ligand-free Sonogashira cross-coupling reaction conditions. The synthesised 3-aminoindole derivatives were confirmed using spectroscopic techniques. The resulting 3-aminoindole derivatives were biologically evaluated against Mycobacterium tuberculosis and Plasmodium falciparum. For example, indole derivatives 10a (7.813 µM) and 10j (8.332 µM) were the most active derivatives in the CAS and ADC media, respectively. |
