Design, synthesis, and biological evaluation of alcyopterosin A and illudalane derivatives as anticancer agents Original Research Article

The synthesis of alcyopterosin A and a series of new derivatives possessing an illudalane skeleton is described. The DNA binding properties of these compounds have been examined and compared to those of reference drugs using a UV spectroscopy technique. The antitumor activity of selected compounds against a panel of 60 human tumor cell lines was tested in the in vitro anticancer screening of the National Cancer Institute. Redox properties were also evaluated. Tested compounds showed significant DNA affinity, derivatives 6 and 15 exhibited remarkable antiproliferative activity and have been identified as new leads in the antitumor strategies.
