摘要:
An immunoassay method and analytical elements for detecting carbamazepine drugs, for example, in body fluids, is described. The immunoassay method comprises:(A) contacting a liquid sample, containing carbamazepine, with a labeled carbamazepine analogue in the presence of antibodies for carbamazepine under conditions that promote the formation of carbamazepine/antibody immunocomplexes; and(B) determining the quantity of the drug in the liquid by measuring bound or unbound labeled drug analogue; characterized in that the labeled carbamazepine comprises:(1) a label, of the type used in immunoassays, having an amine or sulfhydryl group;(2) a carbamazepine nucleus; and(3) a linking chain linking the carboxamide group of the carbamazepine nucleus to the label, said linking chain having about 4 to about 40 atoms consisting of:(a) alkylene groups; and(b) heterocyclic ring groups, each group being joined into the linking group through chemical groups selected from(a) esters,(b) amides,(c) heteroatoms selected from --O--, --S--, and --NR--; wherein each R independently represents hydrogen or C.sub.1 to C.sub.6 alkyl; and(d) carbonyl groups.The elements of the invention are preferably dry, thin film analytical elements comprising a labeled carbamazepine analogue as described.

The invention is directed to labeled drug hapten analogues comprising:(A) a label, of the type used in immunoassays, having an amine or sulfhydryl group;(B) a drug hapten nucleus selected from barbiturates or hydantoins and(C) a linking chain linking the 3-position of the drug hapten nucleus to the label through a carbonyl bridge.

The invention is directed to an immunoassay for a thyronine derivative comprising:A. contacting a liquid sample, containing a thyronine derivative, with a labeled thyronine hapten analogue of the derivative in the presence of antibodies for the thyronine derivative under conditions that promote the formation of antibody-thyronine immunocomplexes; andB. determining the bound or unbound quantity of the thyronine derivative in the liquid; characterized in that the labeled thyronine derivative comprises:(i) a label, of the type used in immunoassays, having an amine or sulfhydyl group;(ii) a thyronine nucleus and(iii) a linking chain linking the label to the thyronine nucleus.

A labeled carbamazepine analogue is described comprising:(A) a label, of the type used in immunoassays, having an amine or sulfhydryl group such as horseradish peroxidase;(B) a carbamazepine nucleus; and(C) a linking chain linking the carboxamide group of the carbamazepine nucleus to the label, said linking chain having about 4 to about 40 atoms consisting of:(1) C.sub.2 to C.sub.6 alkylene groups; and(2) 5 to 7 membered heterocyclic ring groups, each group being joined into the linking group through chemical groups selected from(a) esters,(b) amides(c) heteroatoms selected from --O--, --S--, and --NR--; wherein R represents hydrogen or C.sub.1 to C.sub.6 alkyl; and(d) carbonyl.The new labeled analogues are useful in immunoassay elements and processes for detection of carbamazepine drugs, for example, in body fluids.
