Amino Derivatives of Natural Epoxyalantolactone: Synthesis and Cytotoxicity toward Tumor Cells

Resumo

Reactions of natural epoxyalantolactone with primary and secondary amines, which lead to hydrated benzo[g]furo[4,3,2-cd]indolones and eudesmane-type amino derivatives, respectively, have been studied. Epoxyalantolactone conjugates have been synthesized with the involvement of pharmacophoric amines, and their cytotoxic activity toward some tumor cell lines has been tested. The involvement of the signaling pathway of protein p53 in the death of tumor cells, the contribution of oxidative stress, and the induction of apoptosis have been investigated in experiments in vitro.
