Genel Bakış

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.

Kimyasal Süreç

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

Hammaddeler

  • 6-APA (6-aminopenicillanic acid) — Enzymatic cleavage of penicillin G (Beta-lactam core)
  • D-p-Hydroxyphenylglycine (D-HPG) — Enzymatic resolution or fermentation (Side-chain amino acid)
  • Penicillin G acylase (enzyme) — Recombinant E. coli (Biocatalyst)

Son Ürünler

  • Amoxicillin trihydrate (C₁₆H₁₉N₃O₅S·3H₂O) — Broad-spectrum antibiotic (Compendial grade)

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.
