Methylphenidate is a psychostimulant drug used to treat attention deficit hyperactivity disorder (ADHD) and narcolepsy. It is a prodrug of the active compound, 2-phenyl-2-(2-piperidin)acetic acid (Ritalinic acid), which inhibits the reuptake of dopamine and norepinephrine into the presynaptic neuron. Methylphenidate can be detected by LC-MS/MS in wastewater, providing an analytical method for predicting the presence of this substance in wastewater treatment plants. This drug has minimal toxicity in model organisms and can be metabolized by methylation to form a glucuronide conjugate. Methylphenidate has been shown to increase locomotor activity when administered at low doses, but not at high doses. At high doses, it increases locomotor activity up to 3 hours after administration and decreases locomotor activity 1 hour after administration.

Eslicarbazepine acetate is an anticonvulsant drug that has been shown to be effective in reducing the frequency of seizures. It is a prodrug and is metabolized by esterases to form the active form, eslicarbazepin acetate. Eslicarbazepine acetate inhibits glutamate release by acting on the glutamate transporter, which prevents depolarization of the mitochondrial membrane potential, leading to inhibition of epileptic activity. Eslicarbazepine acetate also decreases brain levels of GABA and increases levels of polyamines such as spermidine and spermine, which are neuroprotective. There are some reports of hepatic impairment when eslicarbazepine acetate is used with other drugs that are metabolized through this organ (e.g., valproic acid).
Eslicarbazepine acetate can cause chemical stability issues when exposed to light or air due to oxidation reactions. It may also react

5-Carboxyfluorescein diacetate is a reactive dye that can be used as a model system to study the effects of reactive species on biological molecules. It has been shown to inhibit mitochondrial membrane potential and activate detoxification enzymes in rats. 5-Carboxyfluorescein diacetate also induces apoptosis in human leukemia cells and inhibits the proliferation of human breast cancer cells. The effect of 5-carboxyfluorescein diacetate on collagen synthesis in a rat wound healing model has been investigated, with an increase in collagen found after treatment. This drug can also cause immunomodulatory effects by inhibiting macrophage activity and increasing T lymphocytes.

Phenylboronic acid is a natural compound that has been shown to inhibit the growth of squamous carcinoma cells. The optical sensor can be used to measure the amount of phenylboronic acid in a solution. The sensor is made from a thin film of colloidal gold, which changes color in response to phenylboronic acid. This method of detection is not as accurate as other methods and can only be used with low concentrations. Phenylboronic acid has been shown to have anti-inflammatory properties, which may be due to its ability to inhibit toll-like receptor 4 and toll-like receptor 6 signaling pathways.

3,5-Diacetoxybenzoic Acid is a monomer that belongs to the group of amides. It has been shown to have an inhibitory effect on the cross-linking reaction of amide bonds with UV irradiation. This monomer copolymerizes with acrylic acid and acrylamide to form stable emulsions with good surface properties. 3,5-Diacetoxybenzoic Acid is used as a co-monomer for trifunctional chloroformates in order to synthesize polymers with diameters of less than 100 nm. The polymerization temperature and morphology are dependent on the concentration of 3,5-Diacetoxybenzoic Acid. Matrix-assisted laser desorption/ionization (MALDI) has been used to characterize the polymerized 3,5-Diacetoxybenzoic Acid.

3-Hydroxy-4-methylbenzoic acid is a cardiotonic glycoside that has been used in the treatment of cardiac arrhythmia. It has been shown to inhibit the enzyme persulfate, which is involved in the activation of hydrogen peroxide and may be responsible for the therapeutic effect of 3-hydroxy-4-methylbenzoic acid.
