Three side chain analogs of didemninB were synthesized. All three analogs of the only conventional type II β-turn present in didemninB differed in the functionality incorporated in the threonine residue. The cytotoxic activities of these analogs were evaluated, and one of them exhibited weak activity.

The synthesis of four benzophenone-containing analogues of the antiproliferative natural product didemnin B is presented. In vitro protein biosynthesis inhibition potency and antitumor activity were evaluated. The results indicate that all four analogues are biologically active and could serve as photoaffinity reagents for the study of receptor-binding interactions of didemnins. These analogues could also be useful in studying antitumor effects of didemnins. (C) 2001 Elsevier Science Ltd. All rights reserved.
