Dihydropyridine precursors of elastin crosslinks

Biochimica et Biophysica Acta (BBA) - General Subjects, 1978
Dihydrodesmosine and dihydroisodemosine are dihydropyridines which are believed to be the immediate biosynthetic precursors of desmosine and isodesmosine, the stable pyridinium ion crosslinks of elastin. It has recently been reported that appreciably amounts of dihydrodesmosine and dihydroisodesmosine accumulate in elastin.

Stability and reactivity of alkylidene dihydropyridines

Organic & Biomolecular Chemistry
We study the effect of pyridine and chloroformate structure on the stability and reactivity of alkylidene dihydropyridines using NMR trends, measured and calculated oxidation potentials, and decomposition studies.

Dihydropyridines As Antihypertensive Agents

1986
Vascular smooth muscle tone is increased by inward transmembrane flux of Ca2+ through voltage-dependent and receptor-operated channels, as well as from intracellular stores. Calcium entry blockers selectively and reversibly reduce the influx of Ca2+ into the cell through the cell membrane and from bound sites within the cell.
