CAS 638-23-3

Carbocysteine

Description:

Carbocysteine, with the CAS number 638-23-3, is a synthetic amino acid derivative that is primarily used as a mucolytic agent. It is characterized by its ability to break down mucus in the respiratory tract, making it easier to expel. Structurally, carbocysteine is a thiol-containing compound, which contributes to its biochemical activity. It is known to enhance the clearance of mucus by reducing its viscosity and promoting ciliary function in the airways. Additionally, carbocysteine has antioxidant properties, which may help protect cells from oxidative stress. The substance is typically administered orally and is well-absorbed in the gastrointestinal tract. Its therapeutic applications are mainly in the treatment of chronic respiratory conditions, such as chronic obstructive pulmonary disease (COPD) and bronchitis. While generally well-tolerated, potential side effects may include gastrointestinal disturbances. Overall, carbocysteine is valued in clinical settings for its efficacy in improving respiratory function and facilitating mucus clearance.

S-(Carboxymethyl)-L-cysteine

CAS: 638-23-3

S-(Carboxymethyl)-L-cysteine (CMC) is a thiol containing compound that is used as a dietary supplement. It has been shown to have beneficial effects on chronic cough and asthma symptoms in two-way crossover studies with human subjects. CMC has also been shown to reduce the production of proinflammatory mediators by inhibiting toll-like receptor 4 (TLR4) activation, which is important for the development of respiratory problems. CMC has also been shown to inhibit mitochondrial functions in cells and produce side effects such as light sensitivity and stomach upset when taken at high doses.
