<mods:abstract>[EN] Chemomodulation of natural cyclolignans as podophyllotoxin has been a successful&#xd;
approach to obtain semisynthetic bioactive derivates. One example of this approach is&#xd;
the FDA‐approved drug etoposide for solid and hematological tumors. It differs from&#xd;
the antimitotic activity of the natural product in its mechanism of action, this drug&#xd;
being a topoisomerase II inhibitor instead of a tubulin antimitotic. Within the&#xd;
molecular requirements for the activity of these compounds, the trans‐γ‐lactone&#xd;
moiety presented in the parent compound has always been a feature to be explored to&#xd;
chemomodulate its bioactivity. In this study, we have obtained different compounds&#xd;
that comply with the molecular characteristics for antitubulin and antitopoisomerase II&#xd;
activity combined in a single molecule. Furthermore, we explored the influence of the&#xd;
trans‐lactone moiety on the final activity, finding that the cis‐lactone was also interesting&#xd;
in terms of bioactivity. The best values of cytotoxicity and cell cycle inhibition&#xd;
were obtained for a compound lacking the lactone ring, thus mimicking the podophyllic&#xd;
aldehyde functionalization, a selective antimitotic podophyllotoxin derivate.&#xd;
The analogs with cis‐lactone also presented interesting cytotoxic activity. The present&#xd;
study illustrates the potential of the chemomodulation of natural products such as&#xd;
natural cyclolignan podophyllotoxin derivates for the discovery of new antitumor&#xd;
agents.</mods:abstract>
