Introduction of an Immunochemical Label in a Cytidine Analogue
摘要:
A new immunochemical label was synthesized and used as an artificial hapten to obtain a monoclonal antibody that specifically recognizes it. The new cytidine analogues, 5-methyl-4-N-(4-[6-(p-bromobenzoylamido)caproylamido]but-1-yl)-2'-deoxycytidine and 4-N-[epsilon-(p-bromobenzoylamido)caproylamido]cytidine which could be useful for nonradioactive detection of DNA and RNA, were also synthesized.
Synthesis of 5-Methyl-2′-<i>O</i>-Deoxycytidine Analogs to Determine Monoclonal Antibody Specificity in the Recognition of the 6-(<i>p</i>-Bromobenzoylamino) Caproyl Radical
Eight new p-bromobenzoyl derivatives of 5-methyl-2'-O-deoxycytidine analogs, substituted at the Lt-position, were synthesized. The best conditions for obtaining 5-methyl-4-N-aminoalkyl-2'-O-deoxycytidine from 3',5'-di-O-acetyl-4-(1,2,4-triazol-1-yl)-2'-O-deoxythymidine were studied. The nucleoside analogs were used to identify the fragment of the 6-(p-bromobenzoylamino)caproyl radical that binds to the monoclonal antibody obtained against it and to define an affinity scale of monoclonal antibody against them.
