  Restricted Conformation Analogues of an Anthelmintic Cyclodepsipeptide

  摘要：

  Six analogues of the anthelmintic cyclodepsipeptide PF1022A were prepared, each containing a small ring fused to the macrocycle to restrict the number of conformations the larger ring can adopt. It was anticipated that such conformational changes could lead to enhanced biological activity and selectivity. The analogues form two series of three members each. In one series, a carbon-based molecular bridge joins the methyl of a leucine residue with the methyl of its closest lactic acid residue to form five-, six-, and seven-membered lactam rings. In the second series, a leucine residue is replaced with five-, six-, and seven-membered nitrogen heterocycles. Decreasing the size of the small ring in the lactam. series increasingly distorts the macrocycle and consistently decreases activity relative to PF1022A. In the leucine series, a similar trend is observed. Molecular modeling of PF1022A along with the analogues described herein suggests that the ability to exist in a highly symmetrical conformational state is a necessary condition for biological activity.

• Generation of a small library of cyclodepsipeptide PF1022A analogues using a cyclization-Cleavage method with oxime resin

  N-Methyloctadepsipeptides attached to an oxime resin were cyclized by heating them in refluxing ethyl acetate for 2 days to give cyclodepsipeptide PF1022A analogues. By using this method, we generated a small library of PF 1022A analogues (2), several of which possessed anthelmintic activity, based on an in vitro assay. (C) 2002 Elsevier Science Ltd.
