    • PURPOSE: A method for preparing a beta-lactam antibiotic is provided. The class of beta-lactam antibiotics, such as penicillin and cephalosporin antibiotics comprises a great variety of compounds, all having their own activity profile. In general, beta-lactam antibiotics consist of a nucleus, the so-called p- lactam nucleus, which is linked through its primary amino group to the so-called side chain via a linear amide bond. CONSTITUTION: Provided is a method for preparing a beta -lactam antibiotic, wherein an N-substituted beta -lactam, having general formula (I), wherein R0 is hydrogen or C1-3 alkoxy; Y is CH2, oxygen, sulfur, or an oxidized form of sulfur; Z is (a), (b), (c) or (d), wherein R1 is hydrogen, hydroxy, halogen, C1-3 alkoxy, optionally substituted, optionally containing one or more heteroatoms, saturated or unsaturated, branched or straight C1-5 alkyl, preferably methyl, optionally substituted, optionally containing one or more heteroatoms C5-8 cycloalkyl, optionally substituted aryl or heteroaryl, or optionally substituted benzyl; and X is (CH2)m-A-(CH2)n, wherein m and n are the same or different and are chosen from the group of integers 0, 1, 2, 3 or 4, and A is CH=CH, CC, CHB, C=O, optionally substituted nitrogen, oxygen, sulfur or an optionally oxidized form of sulfur, and B is hydrogen, halogen, hydroxy, C1-3 alkoxy, or optionally substituted methyl, or a salt thereof, is contacted with at least one dicarboxylate acylase, or a functional equivalent thereof, and reacted with a precursor for a side chain of the beta -lactam antibiotic in the presence of at least one penicillin acylase, or a functional equivalent thereof
    • 目的:提供一种制备β-内酰胺抗生素的方法。 β-内酰胺类抗生素类,如青霉素和头孢菌素类抗生素包括各种各样的化合物,均具有自己的活性。 一般来说,β-内酰胺抗生素由细胞核组成,即所谓的β-内酰胺核,其通过其伯氨基与所谓的侧链通过线性酰胺键连接。 构成:提供制备β-内酰胺抗生素的方法,其中具有通式(I)的N-取代的β-内酰胺,其中R 0是氢或C 1-3烷氧基; Y是CH 2,氧,硫或硫的氧化形式; Z是(a),(b),(c)或(d),其中R 1是氢,羟基,卤素,C 1-3烷氧基,任选地被取代,任选地含有一个或多个杂原子,饱和或不饱和的,支链或直链C1 -5烷基,优选甲基,任选地被取代,任选地含有一个或多个杂原子C5-8环烷基,任选取代的芳基或杂芳基,或任选取代的苄基; 并且X是(CH 2)mA-(CH 2)n,其中m和n相同或不同,并且选自整数0,1,2,3或4,并且A是CH = CH,CC,CHB ,C = O,任选取代的氮,氧,硫或任选氧化形式的硫,B是氢,卤素,羟基,C 1-3烷氧基或任选取代的甲基或其盐与至少一种 二羧酸酰基转移酶或其功能等同物,并在至少一种青霉素酰基转移酶或其功能等同物的存在下与β-内酰胺抗生素的侧链前体反应
