3,4-Dinitrobenzoic acid is a nitrobenzoic acid that has a hydrogen bond. 3,4-Dinitrobenzoic acid is activated by the loss of a proton and it reacts with amines to form diazonium salts. It can be found in plants and animals as an intermediate in the metabolism of tyrosine and tryptophan. 3,4-Dinitrobenzoic acid is used in analytical chemistry to detect the presence of amines. The functional groups on 3,4-dinitrobenzoic acid are carboxylic acid and nitro. Ribulose is an example of a molecule containing these functional groups.

4-Mercaptobenzoic acid is a receptor antagonist that binds to the benzodiazepine site of the GABAA receptor and blocks the action of GABA. This drug has been shown to be useful in tissue culture studies, where it inhibits the growth of cells by interfering with cell division. 4-Mercaptobenzoic acid has also been shown to inhibit sodium citrate uptake into human red blood cells in vitro, which may be due to its ability to bind with hydrogen bonding interactions or ionic interactions. 4-Mercaptobenzoic acid enhances pluronic p123 and fetal bovine serum as a substrate for tissue culture cells, which may be due to its ability to inhibit inhibitor molecules.

Tak-659 is an amide compound that inhibits the serine protease activity of a number of enzymes, including cathepsin B and L. Tak-659 has been shown to have inhibitory effects on inflammation in animal models by inhibiting the production of inflammatory cytokines. Tak-659 has also been shown to impair protein synthesis in gram-negative bacteria, such as Escherichia coli and Pseudomonas aeruginosa. The mechanism for this inhibition is not entirely clear but may be due to tak-659 binding to the ribosomal RNA near the peptidyl transferase center, blocking the entry of amino acids into the ribosome. Tak-659 binds with high affinity to adenosine receptors and has been shown to reduce levels of inflammatory cytokines in mouse tumor cells.
