7-Azaindole is the starting material for the synthesis of azaserotonin. Its derivatives are of great value in drug development, for example, as the backbone of protein kinase B (PKB/Akt) inhibitors. 7-Azaindole and its derivatives have a variety of biological activities, for example, 7-azatryptophan is able to inhibit the growth of tobacco and carrot cells. In addition, it also binds to the Erm enzyme (methyltransferase family), thereby conferring antibiotic resistance.
