Application

3,4-Diaminopyridine can be used as a heterocyclic building block to prepare:      
  • Imidazo[4,5-c]pyridine, an important scaffold used for the preparation of CP-885316.     
  • 9-Azajulolidine derivatives, which are used as efficient organocatalysts for acylation and aza-Morita-Baylis-Hillman reaction.      
  • 2-Phenylpyrido[3,4-b]pyrazine by condensation reaction with α-methylsulfinylacetophenone in benzene/acetic acid as a solvent.

The effects of natural polymeric alkylpyridinium salt (nPoly-3-APS), a potent acetylcholinesterase inhibitor isolated from the marine sponge Reniera sarai, were studied on isolated mouse phrenic nerve-hemidiaphragm muscle preparations using electrophysiological approaches. nPoly-3-APS inhibited nerve-evoked isometric muscle twitch and tetanic contraction

New heterocyclic derivatives of 9-azajulolidine have been synthesized and characterized with respect to their nucleophilicity and Lewis basicity. The Lewis basicity of these bases as quantified through their theoretically calculated methyl-cation affinities correlate well with the experimentally measured reaction rates
