일반 설명

1-Cyano-4-dimethylaminopyridinium tetrafluoroborate is an organic cyanylating agent also termed CDAP. It is a unique cystine-labeling reagent due to its reactive nature under acidic conditions. This feature provides CDAP an advantage over other sulfhydryl labeling agents, as it can avoid potential thiol-disulfide exchange.

애플리케이션

1-Cyano-4-dimethylaminopyridinium (CDAP) has been used in the synthesis of conjugate vaccines as a cyanylating agent. Activation of cellulose dialysis membrane for immunosensor applications used CDAP as an activation agent.

특징 및 장점

When compared to Cyanogen Bromide (CNBr), a similar reagent, CDAP is:

  • Easier to use.
  • Can operate at lower pH levels.
  • Fewer side reactions.
  • Cyanogen Bromide is hazardous in nature.

This study presents a carrier system for boron, potentially useful in boron neutron capture therapy (BNCT). Na2B12H11SH (BSH) was covalently coupled to dextran derivatives. This was accomplished in two ways. The first method comprises activation of dextran with 1-cyano-4-(dimethylamino)pyridine (CDAP)

Some gliomas, melanomas and squamous carcinomas have large numbers of EGF receptors which could, in these cases, be used for targeting with toxic agents. We investigated whether EGF could be conjugated to dextran, which is a suitable carrier for toxic

Trapping folding intermediates of cystinyl proteins by covalent modification of free sulfhydryl groups provides the opportunity for isolation, purification, and structural elucidation of individual species. The disulfide structure of the intermediates, coupled with their temporal abundance, provides a 'snapshot' of
