Novel alpha-amino-3-hydroxy-5-methylisoxazole-4-propionate receptor antagonists: Synthesis and structure-activity relationships of 6-(1H- imidazol-1-yl)-7-nitro-2,3(1H,4H)-pyrido[2,3-b]pyrazinedione and related compounds

We have synthesized and evaluated azaquinoxalinediones 3a-c for their activity in inhibiting [3H]AMPA binding from rat whole brain. It was found that the azaquinoxalinedione nucleus functions as a bioisostere for quinoxalinedione in AMPA receptor binding. The detailed structure-activity relationships of 6- and/or 7-substituted 2,3(1H,4H)-pyrido[2,3- b]pyrazinedione derivatives 4, 7-10, 13, 15, and 16 showed some differences in comparison with those of the corresponding substituted quinoxalinediones, including 6-(1H-imidazol-1-yl)-7-nitro-2,3(1H,4H)-quinoxalinedione (1) (YM90K). The X-ray study exhibited that conformation of the 7-nitro group of 1 ¡¤ HCl was nearly coplanar with the quinoxaline ring, whereas the 6- imidazol1-yl group was rotated with respect to the aromatic ring. From the glycine site on NMDA receptor binding study, it is indicated that bulkiness of 6-substituents on pyridopyrazinediones may be responsible for the selectivity against the glycine site. Among the series of azaquinoxalinediones, 6-(1H-imidazol-1-yl)-7-nitro-2,3(1H,4H)-pyrido[2,3- b]pyrazinedione (8c) exhibited a combination of the best affinity to the AMPA receptors with a K(i) value of 0.14 muM and selectivity against the glycine site (no affinity at 10 muM). In vivo, 8c also protected against sound- induced seizure in DBA/2 mice (minimum effective dose, 10 mg/kg ip).

Methylglyoxal Metabolism and Aging-Related Disease: Moving from Correlation toward Causation

Methylglyoxal (MG) is a ubiquitous metabolite that spontaneously reacts with biopolymers forming advanced glycation end-products (AGEs). AGEs are strongly associated with aging-related diseases, including cancer, neurodegenerative diseases, and diabetes. As the formation of AGEs is nonenzymatic, the damage caused by MG and AGEs has been regarded as unspecific. This may have resulted in the field generally been regarded as unappealing by many researchers, as detailed mechanisms have been difficult to probe. However, accumulating evidence highlighting the importance of MG in human metabolism and disease, as well as data revealing how MG can elicit its signaling function via specific protein AGEs, could change the current mindset, accelerating the field to the forefront of future research.

TAUTOMERISM OF DERIVATIVES OF AZINES. 17. EFFECT OF SOLVENTS ON THE POSITION OF THE AZINYL-YLIDENE TAUTOMERIC EQUILIBRIUM OF SUBSTITUTED AZINYLMETHANES

The effect of solvents on the position of the azinyl-ylidene tautomeric equilibrium in series of azinylmethanes was studied.It was shown that an increase in the polarity of the solvent leads to stabilization of the ylidene tautomer; the sensitivity of the tautomeric equilibrium to the effects of the solvent depends on the form of the side fragment that undergoes tautomerization.It was concluded that stabilization of the ylidene tautomeric form by polar solvents is a general tendency in series of prototropic equilibrium of the azinyl-ylidene type as a whole.
