Erythrosine B (also known as Red No. 3), a Food and Drug Administration (FDA)-approved red food dye, is found in cosmetics and food. It is also used as a plasma stain for nerve cells and staining bacteria in soil. It was studied the modulating capabilities of erythrosine B on amyloid-beta peptide (Aβ) aggregation and Aβ-associated impaired neuronal cell function. It is known, that aggregation Aβ is closely linked to the development of Alzheimer's disease pathology.

Sodium Lauryl Sulfate (SLS) is an anionic surfactant naturally derived from coconut and/or palm kernel oil. It usually consists of a mixture of sodium alkyl sulfates, mainly the lauryl. It is a widely used and inexpensive chemical found in many mainstream personal hygiene products such as shampoos, toothpastes, soaps, detergents and body wash. SLS is a detergent and surfactant, which essentially means that it breaks surface tension and separates molecules in order to allow better interaction between the product and your hair. It is also widely used as a skin irritant when testing products used to heal skin conditions. It was found that SLS represented a potential candidate for the use as a topical microbicide to prevent the sexual transmission of HIV-1, herpes, human papillomavirus and possibly other sexually transmitted pathogens. The mechanism of action of SLS involves the solubilization of the viral envelope and/or the denaturation of envelope and/or capsid proteins.

Bifendate is a synthetic intermediate of Schisandrin C and also an anti-HBV drug used in Chinese medicine for the treatment of chronic hepatitis B. Following the intake of Bifendate in rats, the drug was observed to improve liver function by increasing the detoxification process, reducing pathological lesions, and accelerating hepatocyte regeneration. Bifendate can also function as a membrane-stabilizing agent to protect the cell from damage. After treatment with Bifendate, the protein metabolic processes of hepatitis patients were improved, with increased serum albumin levels and decreased globulin levels. Bifendate is a potent inducer of cytochrome proteins (CYPs) and can result in clinically significant interactions. It has been proposed that the increased detoxification capability of Bifendate originates from an increase in the level of P450. Bifendate may function as a protecting agent to prevent drug-induced liver dysfunction by increasing the activity of CYP450.

Huperzine A is a plant alkaloid derived from Club moss plant, Huperzine serrata, which is a member or the Lycopodium species. Huperzine-A is in phase III clinical trial in the USA (Alzheimer disease) and is available as a dietary supplement. It selectively and reversibly inhibits acetylcholinesterase. Huperzine A is also a NMDA receptor antagonist, which protects the brain against glutamate induced damage, and it increases nerve growth factor levels. Huperzine A is used for Alzheimer's disease, memory and learning enhancement, and age-related memory impairment. It is also used for treating a muscle disease called myasthenia gravis, for increasing alertness and energy, and for protecting against agents that damage the nerves such as nerve gases. It can cause some side effects including nausea, diarrhea, vomiting, sweating, blurred vision, slurred speech, restlessness, loss of appetite, contraction and twitching of muscle fibers, cramping, increased saliva and urine, inability to control urination, high blood pressure, and slowed heart rate. Various medications used for glaucoma, Alzheimer's disease, and other conditions (Cholinergic drugs) interacts with Huperzine A.

Zopiclone (brand names Zimovane and Imovane) is a nonbenzodiazepine hypnotic agent used in the treatment of insomnia. The therapeutic pharmacological properties of zopiclone include hypnotic, anxiolytic, anticonvulsant, and myorelaxant properties. Zopiclone and benzodiazepines bind to different sites on GABAA-containing receptors, causing an enhancement of the actions of GABA to produce the therapeutic and adverse effects of zopiclone. The metabolite of zopiclone called desmethylzopiclone is also pharmacologically active, although it has predominately anxiolytic properties. One study found some slight selectivity for zopiclone on α1 and α5 subunits, although it is regarded as being unselective in its binding to α1, α2, α3, and α5 GABAA benzodiazepine receptor complexes. Desmethylzopiclone has been found to have partial agonist properties, unlike the parent drug zopiclone, which is a full agonist. The mechanism of action of zopiclone is similar to benzodiazepines, with similar effects on locomotor activity and on dopamine and serotonin turnover. A meta-analysis of randomised controlled clinical trials that compared benzodiazepines to zopiclone or other Z drugs such as zolpidem and zaleplon has found few clear and consistent differences between zopiclone and the benzodiazepines in sleep onset latency, total sleep duration, number of awakenings, quality of sleep, adverse events, tolerance, rebound insomnia, and daytime alertness. After oral administration, zopiclone is rapidly absorbed, with a bioavailability around 75–80%. Time to peak plasma concentration is 1–2 hours. High-fat meal preceding zopiclone administration does not change absorption (as measured by AUC), but reduces peak plasma levels and delays its occurrence, thus may delay the onset of therapeutic effects. The pharmacokinetics of zopiclone in humans are stereoselective. After oral administration of the racemic mixture, Cmax (time to maximum plasma concentration), area under the plasma time-concentration curve (AUC) and terminal elimination half-life values are higher for the dextrorotatory enantiomers, owing to the slower total clearance and smaller volume of distribution (corrected by the bioavailability), compared with the levorotatory enantiomer. In urine, the concentrations of the dextrorotatory enantiomers of the N-dimethyl and N-oxide metabolites are higher than those of the respective antipodes. Zopiclone is sometimes used as a method of suicide. It has a similar fatality index to that of benzodiazepine drugs, apart from temazepam, which is particularly toxic in overdose.
