The effect of replacing one of the proline residues in either unsubstituted homochiral or heterochiral diproline segments with either a 2- or a 3-substituted prolyl residue on the allowed conformational of the diproline template has been examined. In heterochiral (L-D)

The structural consequences derived from the incorporation of either a methyl or a phenyl group at the α carbon of proline were recently investigated by quantum mechanical calculations (J Org Chem 2008, 73, 3418). In this work, the effect produced

C(alpha)-methyl-L-proline, or L-(alphaMe)Pro, is probably the most conformationally constrained alpha-amino acid. In particular, its omega and phi torsion angles are restricted to about 180 and -60 degrees, respectively, and only three ranges of values are theoretically available for psi in

A structure-activity analysis of peptides containing backbone C alpha-methyl modification at the P4 site of the angiotensinogen sequence led to the discovery of potent renin inhibitors with apparent in vitro metabolic stability. Boc-alpha-MePro-Phe-His-Leu psi[CHOHCH2]Val-Ile-Amp dicitrate (Va) is a potent inhibitor

Methylation at the C(alpha)-position of a Pro residue was expected to lock the preceding tertiary amide (omega) torsion angle of the resulting (alphaMe)Pro to the trans disposition and to restrict the phi,psi surface to the single region where the 3(10)/alpha-helices
