  Lipodiscamides A–C, New Cytotoxic Lipopeptides from Discodermia kiiensis

  摘要：

  Lipodiscamides A-C, three new lipodepsipeptides, were characterized from the marine sponge Discodermia kiiensis. These structurally rare cyclic lipodepsipeptides were found to possess an unprecedented dilactone macrocycle and, thus, represent a new family of lipopeptides. They are the only lipopeptides bearing 4S-hydroxy-trans-2-enoate, and noncanonical amino acids, l-3-ureidoalanine (Uda), E-dehydronorvaline (Denor), and d-citrulline (Cit). MTT assays against P388 and HeLa cells revealed the moderate cytotoxicity of all three compounds.

  A number of amino acid derivatives of DL-Zra/w-epoxysuccinic acid, with a general formula of R1O-ES-AA-OR2 (ES, DL-trans-epoxysuccinyl group; AA, amino acid residue) were newly synthesized and used for the study of structure-activity relationships of papain inhibition. Branched-alkyl amino acids, such as Leu, He and Val, as AA and hydrogen or an alkyl group substituted with a phenyl or cycloalkyl group as R1 were desirable for activity, respectively. However, R2 or the optical activities of ES and AA not so much influenced on the activity.
