Description
Industrially, amoxicillin has been produced by chemical processes.But, the enzymatic synthesis catalyzed by penicillin G acylase (PGA, E.C.3.5.1.11)is more attractive from the environmental point of view.However, an obstacle for the industrial application of the enzymatic route is the limited product yield due to undesirable hydrolytic reactions.This drawback can be minimized by reducing water activity in the reaction medium.Ionic liquids (ILs) have emerged as an alternative to conventional organic media.This study assessed the feasibility of use of different ILs, protic (PILs) and aprotic (AILs), in the enzymatic synthesis of amoxicillin, by testing the stability of reaction substrates (6-aminopenicillanic acid and phydroxyphenylglycine methyl ester) in these solvents.These compounds were completely stable in AILs.Besides, PGA was active in AILs.In contrast, none of the evaluated PILs was inert for these substrates making unfeasible the use for this enzymatic process.

من الناحية الصناعية، تم إنتاج الأموكسيسيلين عن طريق العمليات الكيميائية. ولكن، التخليق الأنزيمي الذي يحفزه البنسلين جي أسيلاز (PGA، E.C.3.5.1.11)هو أكثر جاذبية من وجهة النظر البيئية. ومع ذلك، فإن عقبة أمام التطبيق الصناعي للطريق الأنزيمي هي العائد المحدود للمنتج بسبب التفاعلات المائية غير المرغوب فيها. يمكن تقليل هذا العيب عن طريق تقليل نشاط الماء في وسط التفاعل. ظهرت السوائل الأيونية (ILs) كبديل للوسائط العضوية التقليدية. قيمت هذه الدراسة جدوى استخدام ILs مختلفة، بروتيك (PILs) و aprotic (AILs)، في التخليق الأنزيمي للأموكسيسيلين، عن طريق اختبار استقرار ركائز التفاعل (حمض 6 - amopenicillanic و phydroxyphenylglycine methyl ester) في هذه المذيبات. كانت المركبات مستقرة تمامًا في AILs، إلى جانب PILBs. لم تكن نشطة في التباين في PILs. لم يتم تقييمها في هذه العملية غير المغذية.Translated Description (English)
