Abstract

As a continuation of the studies aimed at the development of new Anticancer agents derived from the Amaryllidaceae alkaloid lycorine, 35 C1,C2-ether analogues of this natural product were synthesized. The compounds were evaluated for antiproliferative activities in vitro in a panel of tumor cell lines with varied levels of Apoptosis resistance. A strong correlation between the compound lipophilicity and Anticancer activity was observed, indicating that cell permeability properties must be an important determinant in the design of lycorine-based Anticancer agents. A theoretical docking model, consistent with the experimental observations, is presented.
