3-Aminopropanesulfonic acid

Description:

3-Aminopropanesulfonic acid, commonly known as APSA, is an organic compound characterized by the presence of both an amino group and a sulfonic acid group. Its molecular structure consists of a three-carbon chain with an amino group (-NH2) attached to the first carbon and a sulfonic acid group (-SO3H) attached to the third carbon. This compound is a colorless, crystalline solid that is highly soluble in water, making it useful in various biochemical applications. APSA is often utilized as a buffering agent in biological and biochemical research due to its ability to maintain stable pH levels in solutions. It is also recognized for its role in cell culture and as a potential alternative to other buffering agents like Tris. The presence of both the amino and sulfonic acid functional groups contributes to its unique properties, including its zwitterionic nature, which can influence its interactions in biological systems. Overall, 3-Aminopropanesulfonic acid is valued for its versatility and effectiveness in laboratory settings.

Homotaurine

CAS: 3687-18-1

Homotaurine is a secretase inhibitor that has been shown to have anti-Alzheimer's disease effects in vivo. It has been shown to increase serum prolactin levels and improve locomotor activity in mice. Homotaurine also has the ability to inhibit the production of glutamate, an excitatory neurotransmitter, through its inhibition of N-acetyl-L-aspartate (NAA) synthesis. This drug is also an oral prodrug, which can be activated by hydrolysis in the gastrointestinal tract to release homotaurine. The reaction mechanism for this compound is not yet clear but it may involve natural compounds such as choline or acetylcholine.
