General description

4-Morpholinopyridine (MORP) can be synthesized by the reduction of its 1-oxide. It undergoes morpholine ring contraction on reacting with trimethylsilylmethyllithium (TMSCH2Li).

Application

4-Morpholinopyridine may be used in the synthesis of 1-alkyl-4-morpholinopyridinium halides. It may also be used as a secondary enhancer to improve the chemiluminescence of horseradish peroxidase (HRP) catalyzed oxidation of luminol.

Sensitive microplate-based chemiluminescent assay coupled with isothermal circular strand-displacement polymerization reaction (ICSDPR) for DNA detection was developed. The assay sensitivity was improved using a triple amplification strategy based on employment of ICSDPR, streptavidin-polyperoxidase conjugate and an enhanced chemiluminescent reaction. To

In this study, a high sensitivity chemiluminescence enzyme immunoassay (CLEIA) based on novel enhancers was developed. Under optimal conditions, we developed an enhanced chemiluminescence reaction (ECR) catalyzed by horseradish peroxidase (HRP-C) in the presence of 3-(10'-phenothiazinyl) propane-1-sulfonate (SPTZ) and 4-morpholinopyridine
