Diels–Alder reactions between 2- or 3-vinylpyrrolo[2,3-b]pyridine with various dienophiles were investigated. The pyrido[2,3-b]indole adducts 9 and 13 obtained led us to the preparation of potential cytotoxic agents 19 and 20.

side-chain demonstrated higher affinities for poly(dA-dT)(2) than compounds 6, 7 and 11 bearing a dimethylaminoethyl side-chain. Circular and electric linear dichroismmeasurements showed that all five drugs behave as typical DNA intercalating agents. A plasmid cleavage assay was used to evaluate the capacity of the drugs to inhibit human topoisomerase II. Compounds 8 and 12 which bind strongly to DNA
