Conformational study of three endothelin antagonists with 1H NMR at low temperature and molecular dynamics

FEBS Lett. 1994 May 9;344(1):55-60. doi: 10.1016/0014-5793(94)00352-1.

Abstract

The conformations of three endothelin antagonists, a cyclic pentapeptide, a linear tripeptide and a linear hexapeptide, are compared by 1H NMR and molecular dynamics. The three analogues have a Leu and a DTrp side chain which are oriented parallel, and an acidic group next to the DTrp residue.
