Chloramphenicol derivatives are provided for use in preparing antigen conjugates for the production of antibodies specific for chloramphenicol. Specifically, the derivatives have the formula:
wherein:
Q is chalcogen of atomic number 8 to 16 or nitrogen;
pis 0 or 1;
R is a linking group of at least 1 carbon atom and not more than 12 atoms other than hydrogen;
Z is hydrogen, hydroxy, alkoxy of from 1 to 6 carbon atoms, a group forming an activated ester capable of amide formation in an aqueous medium, or a poly(amino acid) which is antigenic or an enzyme;
m is 0 or 1 when Z is a poly(amino acid) and is otherwise 1; and
n is 1 when Z is other than a poly(amino acid) and is otherwise a number between one and the molecular weight of Z divided by 1000. The aryl group is derivatized with a side chain functionalized to provide for a carbonyl functionality to react with amino groups of a poly(amino acid). The conjugate is then injected into a vertebrate for production of antisera which are isolated in conventional ways and find particular use in competitive protein binding assays.
所提供的氯霉素衍生物可用于制备抗原共轭物,以生产氯霉素特异性抗体。具体地说,这些衍生物具有以下式子:
其中
Q 是原子序数为 8 至 16 的绿原酸或氮;
p 为 0 或 1;
R 是至少含有 1 个碳原子且不超过 12 个氢原子的连接基团;
Z 是氢、羟基、1 至 6 个碳原子的烷氧基、能在水介质中形成酰胺的活化酯基团或具有抗原性的聚氨基酸或酶;
当 Z 为聚氨基酸时,m 为 0 或 1,否则为 1;以及
当 Z 不是聚氨基酸时,n 为 1,否则为 1 与 Z 的分子量除以 1000 之间的数值。芳基用侧链官能化衍生,以提供羰基官能团与聚(氨基酸)的氨基反应。然后将共轭物注射到脊椎动物体内,生产抗血清,用传统方法分离抗血清,特别适用于竞争性蛋白质结合试验。
