6,7-Dimethoxycarbostyril is a small molecule that has been shown to induce cell death in cancer cells by inhibiting the chaperone function of heat shock protein 90 (HSP90). HSP90 is a multifunctional molecular chaperone that affects many cellular processes including cell growth, apoptosis and tumorigenesis. 6,7-Dimethoxycarbostyril binds to the ATP binding site of HSP90, preventing it from performing its chaperone role. This leads to inhibition of cell growth and induction of apoptosis. 6,7-Dimethoxycarbostyril has also been shown to inhibit tumor growth in vivo in mouse models and has successfully completed phase I clinical trials at doses up to 2000 mg/day.

(3,4,5-Trimethoxyphenyl)methyl carbinol is a neuroprotective compound that belongs to the class of benzyl alcohols. It has been shown to have neuroprotective effects against daldinia-induced oxidative stress and biotoxicity. This compound has high electron transfer rates and can be used as an electron donor in enzymatic reactions. (3,4,5-Trimethoxyphenyl)methyl carbinol exhibits a high reactivity with alcohols and can be used in the synthesis of other compounds by transferring its alcohol group onto other molecules. The addition of deuterium atoms to this molecule has been shown to increase its reactivity with oxidants.

3-Methoxy-4-nitrobenzoic acid methyl ester is a dianellidin, a type of natural product. It is an ionizing acid that catalyzes the reaction between carboxylic acids and hydroxyl compounds. This compound is used to produce some drugs, such as methyldopate, which is an antiarrhythmic drug that slows heart rate. The catalytic rate of 3-methoxy-4-nitrobenzoic acid methyl ester can be increased by buffers and solvents (e.g., methanol). These compounds increase the concentration of the reactants in solution and reduce the activation energy required for the reaction to take place. Uncatalyzed reactions are slow because there are no molecules to act as intermediates in the process.
