Dihydrexidine hydrochloride is a phosphate ion transport inhibitor that binds to the acetylcholine transporter, and inhibits the uptake of acetylcholine in the brain. It is used as an opioid analgesic, as well as to treat depression, cognitive disorders, and Parkinson's disease. Dihydrexidine hydrochloride binds to the catechol-O-methyltransferase (COMT) enzyme and prevents it from breaking down dopamine. This leads to increased levels of dopamine in the synapse and enhanced transmission of nerve impulses between neurons. Dihydrexidine hydrochloride also has been shown to bind to antigen molecules on cells, which may be important for its antiviral properties.

Regorafenib metabolite M2 oxide (M2O) is a cancer drug that is an inhibitor of multikinase. It was developed as a prodrug for regorafenib, which is used to treat patients with metastatic colorectal cancer and has been shown to be effective against other cancers, such as lung and pancreatic cancer. M2O inhibits the efflux of drugs from cells by binding to the transporter protein P-glycoprotein. This prevents the accumulation of toxic concentrations of regorafenib in cells, which are responsible for its side effects, such as diarrhea and liver damage. The uptake of M2O by cells is also inhibited by light and acidic conditions. Oral administration of M2O leads to increased exposure to regorafenib in the body because it is not metabolized by CYP3A4 enzymes.

L-Valine 2-hydroxyethyl ester tosylate (L-V2HT) is a drug product that is synthesized by custom synthesis. It has high purity, analytical, and natural properties. L-V2HT is metabolized through a number of metabolic transformations, including hydrolysis by esterases or glucuronidases, oxidation by cytochrome P450 enzymes, reduction by glutathione reductase, or conjugation with glucuronic acid. The active form of L-V2HT is metabolized through a number of metabolic transformations, including hydrolysis by esterases or glucuronidases, oxidation by cytochrome P450 enzymes, reduction by glutathione reductase, or conjugation with glucuronic acid. L-V2HT also specifically binds to markers expressed at high levels in Mycobacterium tuberculosis strains (e.g., ESX-1 secretion system protein) and inhibits cell

Dioctyl carbonate is a pharmaceutical preparation used to treat skin conditions. It is a fatty acid ester of carbonic and carbonyl groups in which the two esters are in the same molecule. Dioctyl carbonate is a reaction product obtained by reacting an inorganic acid, such as hydrochloric acid or sulfuric acid, with an alcohol containing two hydroxyl groups and one double bond. This reaction may be facilitated by heating. The film-forming polymer may be polyvinylpyrrolidone, polyvinyl alcohol, or polyacrylic acid. Dioctyl carbonate has been shown to stimulate colony-stimulating factor production and inhibit the proliferation of human epidermal keratinocytes.

Quinidine is a drug that has been used in the treatment of cardiac arrhythmias and as an antiarrhythmic. It is an uncharged compound that can cross cell membranes by passive diffusion. Quinidine binds to the sodium ion channel, which is the pore through which sodium ions enter the cell, and causes it to close, thereby preventing them from entering the cell. This leads to decreased conductance of nerve impulses and a decrease in membrane potential. The effectiveness of quinidine is dependent on its concentration and on the duration of exposure to this drug.
