NPS-ALX-4A is a drug, which has been shown to have cognition-enhancing effects in mice. It is a 5-HT6 receptor antagonist and can be used as an animal model for human cognitive disorders. NPS-ALX-4A was administered orally to control mice and the animals were tested for learning and memory. The study showed that NPS-ALX-4A improved spatial memory in the mouse model. This drug has not been tested on humans, but it has shown cognitive benefits in the mouse model with no significant side effects.

3-(Dimethylamino)-1-(2-thienyl)propanone hydrochloride is a sulfoxide that is used as a solvent. It has been used in the synthesis of benzylsulfoxides and solvents for the manufacture of pharmaceuticals. 3-(Dimethylamino)-1-(2-thienyl)propanone hydrochloride is also a potent compound, which is structurally similar to benzene but with an additional methyl group. 3-(Dimethylamino)-1-(2-thienyl)propanone hydrochloride has been used in the synthesis of melphalan and elemental analysis. The chloride group on its structure makes it soluble in water and organic solvents such as acetonitrile. 3-(Dimethylamino)-1-(2-thienyl)propanone hydrochloride can be synthesized by reacting nitric acid with 2-aminothiophenol and dimethylanil

Poloxamer 407 is a synthetic, non-biodegradable polymer that is used as a surfactant in pharmaceutical preparations. It is typically used to solubilize poorly water-soluble drugs. Poloxamer 407 has been shown to inhibit angiotensin II type 1 receptor blockers and hydrochloric acid, which are involved in the production of stomach acid and regulate blood pressure. The chloride ions present in this polymer are also responsible for its antibacterial properties. It has been shown to be effective against bacteria such as Pseudomonas aeruginosa, Escherichia coli, and Staphylococcus aureus. This polymer can also be used as an active targeting agent for drug delivery systems by attaching it to other molecules with specific biological activities. Poloxamer 407 is soluble in organic solvents that are commonly found in the environment such as halides (e.g., chloride). This polymer also hydrolyzes under basic conditions into potassium ion
