Main Results:

  • The synthesized N,N-dialkylcarbamoyl derivatives exhibited anticellular activity.
  • Derivatives bearing the p-methoxy cinnamoyl group showed significant in vivo antitumor activity.
  • These novel derivatives demonstrated superior antitumor efficacy compared to native duocarmycin SA.

Conclusions:

  • N,N-dialkylcarbamoyl derivatives of duocarmycin SA represent promising anticancer drug candidates.
  • The p-methoxy cinnamoyl moiety enhances in vivo antitumor potency.
  • Further investigation into these derivatives could lead to new cancer therapies.
