Nitrogen-15 NMR spectroscopy of some azines was written by Stefaniak, L.;Roberts, John D.;Witanowski, M.;Webb, G. A.. And the article was included in Organic Magnetic Resonance in 1984.Related Products of 322-46-3 This article mentions the following:
15N NMR shielding data are presented for 56 cyclic azines in 0.5 M DMSO with 0.01 M increments of Cr[CH(COMe)2]3 added for each N atom in the mols. For the polyazines, the 15N signal assignments were based on 2J(NH) interactions and some INDO/S-SOS shielding calculations The effects of α-, β- and γ-Me and conjugated-ring substitution on N shielding are discussed, as are the influences arising from fusion with alicyclic and aromatic rings at various positions. The effects of a 2nd N atom on the shielding of the 1st depend critically on both their relative positions and on the fusion site of conjugated ring systems. In the experiment, the researchers used many compounds, for example, Pyrido[2,3-b]pyrazine (cas: 322-46-3Related Products of 322-46-3).
Pyrido[2,3-b]pyrazine (cas: 322-46-3) belongs to pyrazine derivatives. Pyrazine derivatives have antitumor, antibiotic, anticonvulsant, antituberculous and diuretic effects as well as kinase, enzymatic and potent tubulin and FtsZ polymerization inhibitory activities. Pyrazine-based skeletons were incorporated into agents targeting a range of ailments. Many derivatives were synthesized and evaluated as potential cancer treatments.Related Products of 322-46-3
