Ac-Ala-Ala-Ala-Ala-OMe is a peptidase that hydrolyzes the ester bonds of the hydrophobic amino acid residues, such as alanine, valine, leucine, and isoleucine. This enzyme deacylates and releases these amino acids from the side chain of their corresponding fatty acyl groups. Ac-Ala-Ala-Ala-Ala-OMe also acts on N terminal and C terminal residues. The presence of a scissile bond in the peptide substrate is required for this enzyme to function. Acetylation reactions are concurrent with acylation reactions, which produce an acetylated peptide product.

H-Gly-Gly-His-Ala-OH is a peptide of four amino acids. It has been shown experimentally that the side chain of His is always oriented in the same direction, regardless of the conformation. The proton shift constants and vicinal coupling constants for Gly, Gly and Ala are constant, while His has a variable proton shift constant. The experimental parameters for the molecule have been rationalized by using conformational shifts to explain their variability. For example, the proton shift constants have been found to be dependent on the rotation about an axis perpendicular to the peptide backbone. H-Ala-Gly-Gly-His-OH is a pentapeptide with five amino acids that differs from HGGHAOH by having Ala instead of His at position 1. The vicinal coupling constants are different and so are other experimental parameters.

Bosentan is a potent inhibitor of the uptake of organic anions. It is used in the treatment of pulmonary arterial hypertension and has been shown to be effective against pravastatin-resistant HIV protease inhibitors, such as saquinavir, quinidine, and rosuvastatin. Bosentan inhibits uptake by binding to the transporter protein at a site that does not overlap with the binding site for organic anion substrates. This leads to a change in kinetic parameters for substrates, such as pravastatin and saquinavir. The binding site on bosentan may also be elucidated through monolayer experiments with efflux transporters.
