Application

Isonicotinamide (pyridine-4-carboxamide) can be used as a heterocyclic building block to synthesize:
  • 4-oxo-1,3-thiazinan-3-yl isonicotinamide derivatives as potential anti-tubercular agents.
  • Organotin(IV) complexes of isonicotinamide via synthesis of phosphoramidate ligands for various biological activity studies.
  • Bis-pyridinium isonicotinamide derivatives of 2-(hydroxyimino)-N-(pyridin-3-yl)acetamide as potent reactivators sarin.

It can also be used as a co-former with active pharmaceutical ingredients (APIs) to prepare co-crystals.

Treatment of N-arylisonicotinamides with trifluoromethanesulfonic anhydride triggers intramolecular nucleophilic attack of the aryl ring on the 4-position of the pyridinium intermediate. The products are spirocyclic dihydropyridines which can be converted to valuable spirocyclic piperidines related to biologically active molecules such

On treatment with acylating or sulfonylating agents, N-alkenyl pyridine carboxamides (N-pyridinecarbonyl enamines) undergo a dearomatizing cyclization initiated by pyridine acylation and followed by intramolecular trapping of the resulting pyridinium cation. The products are spirocyclic dihydropyridines which may be further elaborated

A series of low-molecular weight 2,6-diamino-isonicotinamide BACE-1 inhibitors containing an amine transition-state isostere were synthesized and shown to be highly potent in both enzymatic and cell-based assays. These inhibitors contain a trans-S,S-methyl cyclopropane P(3) which bind BACE-1 in a 10s-loop
