Journal ArticleDOI
Conformational analysis of two cyclic analogs of angiotensin: implications for the biologically active conformation.
TL;DR: These conformers of cyclo[Sar1, Cys3, Mpt5]-AT contain "an open turn" in the backbone of the Tyr4-Val5 residues, instead of the earlier proposed beta-like reversal, thus confirming the suggestion that the conformation(s) ensuring binding of AT analogs with specific receptors should not be described in terms of a unique backbone conformer.
Journal ArticleDOI
Impact of azaproline on amide cis-trans isomerism: conformational analyses and NMR studies of model peptides including TRH analogues.
Wei-Jun Zhang,Anders Berglund,Jeff L.-F. Kao,Jean-Pierre Couty,Marvin C. Gershengorn,Garland R. Marshall +5 more
TL;DR: To test the validity of the calculations in view of the experimental data from crystal structures and NMR in organic solvents, [azPro( 3)]-TRH and [Phe(2), azPro(3)]- TRH were synthesized, and their conformational preferences were determined by N MR in polar Solvents as well as the impact of the azPro substitution on their biological activities.
Journal ArticleDOI
Novel cyclic analogs of angiotensin II with cyclization between positions 5 and 7: conformational and biological implications.
Wei-Jun Zhang,Gregory V. Nikiforovich,Jacqueline Pérodin,Darren E. Richard,Emanuel Escher,Garland R. Marshall +5 more
TL;DR: Molecular modeling suggested a possible explanation for the relatively strong binding and the weak partial agonistic activity of compound 9 are due to interaction with AT-1 receptor of only two functionally important groups, namely, the side chains of the His6 and Phe8 residues.
