1,4-Dihydropyridine (DHP) is an organic compound with the formula CH2(CH=CH)2NH. The parent compound is uncommon, [2] but derivatives of 1,4-dihydropyridine are important commercially and biologically. The pervasive cofactors NADH and NADPH are derivatives of 1,4-dihydropyridine. 1,4-Dihydropyridine-based drugs are L-type calcium channel blockers, used in the treatment of hypertension. 1,2-Dihydropyridines are also known. [3] [4]
A recurring feature of 1,4-dihydropyridines is the presence of substituents at the 2- and 6-positions. Dihydropyridines are enamines, which otherwise tend to tautomerize or hydrolyze.[ citation needed]
The dominant reaction of dihydropyridines is their ease of oxidation. In the case of dihydropyridines with hydrogen as the substituent on nitrogen, oxidation yields pyridines:
The naturally-occurring dihydropyridines NADH and NADPH contain N-alkyl groups. Therefore, their oxidation does not yield pyridine, but N-alkylpyridinium cations:
