title: A novel achiral seco-cyclopropylpyrido[e]indolone (CPyI) analog of CC-1065 and the duocarmycins: synthesis, DNA interactions, in vivo anticancer and anti-parasitic evaluation.
abstract: The synthesis of an achiral seco-hydroxy-aza-CBI-TMI analog (8) of the duocarmycins is reported. Its specificity for the DNA minor groove of AT-rich sequences and covalent bonding to adenine-N3 was ascertained by a thermal cleavage assay. Compound 8 was found to be cytotoxic in the nanomolar range against murine and human cancer cells. It was further demonstrated that compound 8 was active against murine melanoma (B16-F0) grown in C57BL/6 mice. Compound 8 was also shown to inhibit the growth of the protozoan parasites Leishmania donovani, Leishmania mexicana, Trypanosoma brucei, and Plasmodium falciparum in culture.
