Обзор

Amoxicillin is a broad-spectrum semi-synthetic penicillin and the most prescribed antibiotic globally. It is produced by enzymatic coupling of 6-aminopenicillanic acid (6-APA) with D-p-hydroxyphenylglycine (D-HPG) using penicillin G acylase. This enzymatic route has largely replaced chemical acylation methods, providing higher selectivity, milder conditions, and dramatically reduced solvent waste. The process exemplifies the successful integration of biocatalysis in pharmaceutical manufacturing.

Химический процесс

6-APA is obtained by enzymatic deacylation of penicillin G using immobilized penicillin G acylase. The 6-APA is then coupled with activated D-HPG methyl ester using the same or similar acylase enzyme under controlled pH and temperature to produce amoxicillin trihydrate.

6-APA + D-HPG-OMe →[Penicillin G acylase, pH 6.5, 25 degrees C] Amoxicillin + CH₃OH

Сырьё

Environmental Impact

The enzymatic process is significantly greener than chemical acylation, eliminating the need for silylation reagents, organic solvents, and cryogenic conditions. Immobilized enzymes can be reused hundreds of times. Wastewater treatment is simplified due to reduced chemical usage.
