Total Synthesis of the Cyclic Depsipeptide Leualacin
摘要:
The fungal metabolite leualacin (1), a potent calcium channel antagonist, was synthesized in 15 steps from commercially available amino acids in 25% overall yield using standard solution methods. The synthesis is general and thus would accommodate the incorporation of amino acid replacements as well as the inclusion of peptide mimics and isosteres.

Leualacin (1), a cyclic depsi-pentapeptide, and its backbone/amide-modified analogs 2-4 were synthesized. Amide analogue 3 exhibited stronger vasodilatory effects. It also strongly inhibited collagen- and arachidonic acid (AA)induced platelet aggregations with IC(50)s of 0.6 mu M and 2.0 mu M, respectively (C) 1999 Elsevier Science Ltd. All rights reserved.
