Verwenden
Isonicotinamide is an isomeric analogue of nicotinamide and a metabolite of isonicotinic thioamide. Isonicotinamide strongly inducde apoptosis in human acute myelomonocytic leukemia cells, HL-60.
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.
Isonicotinamide can also be used as a co-former with active pharmaceutical ingredients (APIs) to prepare co-crystals.
synthetische
synthesis of isonicotinamide: In 6g tert-amyl alcohol, add 100mg ferric oxide, 100mg cobalt tetroxide and 100mg manganese dioxide (mass percentage in the mixture: 4.6%), 60mg 4-cyanopyridine (mass percentage in the mixture: 0.91%), 200uL Water (mass percentage in the mixture: 3.0%), mix well; react at 80°C for 24 hours, the conversion rate of 4-cyanopyridine is 99.0%, and the selectivity of the corresponding Isonicotinamide is 99.0%.
Definition
ChEBI: Isonicotinamide is a pyridinecarboxamide that is the monocarboxylic acid amide derivative of isonicotinic acid. It derives from an isonicotinic acid.
läuterung methode
Recrystallise isonicotinamide from hot water or isopropanol (158.5-159o), and dry it in a vacuum at 100o. The picrate crystallises from aqueous EtOH or H2O and has m 217-218o (214-215o). [Beilstein 22 III/IV 527, 22/2 V 195.]
