Analogues of angiotensin II with cyclohexylalanine (Cha) at position 4 or 8, and analogues of the competitive (type II) angiotensin antagonist [Sar1,Tyr(Me)4]ANG II (Sarmesin) with Cha at position 8, have been prepared by the solid phase method and purified by

The opioid peptide TIPP (H-Tyr-Tic-Phe-Phe-OH, Tic:1,2,3,4-tetrahydroisoquinoline-3-carboxylic acid) was substituted with Dmt (2',6'-dimethyltyrosine) and a new unnatural amino acid, beta-MeCha (beta-methyl-cyclohexylalanine). This double substitution led to a new series of opioid peptides displaying subnanomolar delta antagonist activity and mu agonist or

The amino acid analog L-cyclohexylalanine, which may be considered an analog of the hydrophobic amino acids leucine and valine, was found to thioester-bind to the heavy enzyme of gramicidin S synthetase. The results indicate that it preferably binds to the

Designed coiled-coil heterotrimers are described whose assembly is governed by both hydrophobic and hydrophilic forces. Sterically matched hydrophobic core side-chain packing of alanine and cyclohexylalanine has been shown to promote formation of a 1:1:1 heterotrimer. Manipulation of hydrophilic glutamic acid

The capacity for sequential and specific exchange of single peptides from coiled-coil heterotrimers is investigated. Dual hydrophobic-hydrophilic interface systems permit iterative cycles of pH-triggered strand exchange that can specifically replace one, two, or even all three initial trimer components. The
