Change in the fluorescence of 1,1′-diaryl-2,2′-biimidazoles upon the addition of acid
The optical properties of a series of 1,1′-diaryl-2,2′-biimidazoles were examined. Different transitions were observed in their fluorescence spectra upon changing the electronic properties of the phenyl ring at the C1 and C1′ positions. The presence of a
Imidazol-1-yl and Pyridin-3-yl Derivatives of 4-Phenyl-1,4-dihydropyridines Combining Ca2+ Antagonism and Thromboxane A2 Synthase Inhibition
A series of derivatives of 4-phenyl-1,4-dihydropyridine bearing imidazol-1-yl or pyridin-3-yl moieties on the phenyl ring were synthesized with the aim of combining Ca2+ antagonism and thromboxane A2 (Tx A2) synthase inhib
