N-Acetyl-Thiazolidine -4-carboxylic acid is a pharmaceutical raw material with a chemical structure of n-acetylthiazolidin-4-carboxylic acid. It is a sulfur-containing organic compound commonly used as an intermediate and precursor compound in drug synthesis. ATCA has been widely used in medicine. It is a liver protectant that protects the liver by enhancing the antioxidant capacity of liver cells and reducing liver damage and inflammatory responses. In addition, ATCA also has biological activities such as regulating blood sugar, anti-inflammatory, antibacterial and antioxidant. ATCA can also be used to synthesize other drugs. For example, it is one of the important intermediates in the synthesis of ramipril, a commonly used antihypertensive drug. In addition, ATCA is also involved in the synthesis of several antiviral and antitumor drugs.
Application：
N-Acetyl-Thiazolidine-4-carboxylic acid (ATCA) is a pharmaceutical raw material with many applications. ATCA is mainly used as drug intermediates and synthetic raw materials. It is a derivative of L-cysteine (an amino acid) and has high chemical stability and biological activity. The following are the main application areas of ATCA:
