Methyl-L-tyrosinate is a drug that has been shown to increase the activity of tyrosinase, an enzyme involved in the production of melanin. It also prevents the oxidation of tyrosine and phenylalanine, which are precursors to melanin. Methyl L-tyrosinate has been studied for its potential effects on hepatitis and Parkinson's disease. This drug binds to the hydroxyl group of tyrosinase and inhibits its activity. The inhibition of this enzyme leads to a decrease in melanin synthesis, which may be beneficial for those with vitiligo or other skin disorders where pigment loss is desired. This drug also prevents oxidative carbonylation and functional assays have shown that it has an affinity for potassium ion coordination chemistry.

Alternariol-9-methyl ether is a natural compound that has been shown to have significant cytotoxic effects on murine hepatoma cells. This compound also synergizes with anti-retroviral drugs and has been found to be capable of inducing apoptosis in HIV-infected T cells at low concentrations. Alternariol-9-methyl ether is structurally related to the polycyclic aromatic hydrocarbons, such as alternariol, which are only weakly toxic to mice but are potent pro-apoptotic proteins when bound covalently to DNA. Structural analysis of this compound revealed that it inhibits the binding of a pro-apoptotic protein (Bid) to its target site on dsDNA, preventing Bid from initiating apoptosis. It is thought that this effect may be responsible for its synergistic interaction with active antiretroviral therapy.

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.
