  Beyond the Diketopiperazine Family with Alternatively Bridged Brevianamide F Analogues

  摘要：

  A method for the preparation of 3,5-bridged piperazin-2-ones from a tryptophan proline-based diketopiperazine is described using diphosgene to induce the ring closure. Density functional theory calculations were conducted to study the mechanism of this C-C bond formation. Several derivatives of the thus obtained alpha-chloroamine were synthesized by substitution of the chlorine atom using a range of O-, N-, S-, and C-nucleophiles. This novel class of brevianamide F analogues possess interesting breast cancer resistance protein inhibitory activity.

Forty-two geranylated derivatives were obtained from 15 cyclic dipeptides by using the engineered enzymes. Taking cyclo-l-Trp-l-Trp as an example, the geranyl moiety can be attached to all seven possible positions of the indole nucleus. This study demonstrates a convenient

  A series of C2-arylated analogues of the diketopiperazine brevianamide F has been synthesized using a mild Pd-catalyzed CH-activation procedure. Biological evaluation of the new derivatives in different cell lines shows that this modification is responsible for the remarkable change in activity, turning a mild antibiotic and antifungal natural product (brevianamide F) into novel antitumoral compounds. Furthermore, the approach stated represents a new straightforward and versatile methodology with promising applications in peptidomimetics and medicinal chemistry.
