dihydropyridine (1,4-DHP) nucleus was essential to maintain both β-haematin inhibition and parasite growth-inhibition activities of the analogues. Thus, upon oxidation to a pyridine activity was lost. Comparison of the structural alterations performed on the 1,4-DHP molecule has permitted construction of a structure-activity model for its
filexlib. The major pharmacological actions of 1,4-Dihydropyridine analogs are: 2.1. Antihypertensive agents. Hypertension (HTN) is also known as the 'silent killer' as the condition does not often precipitate major identifiable symptoms. Generally, human beings do not identify and understand blood pressure (BP) elevation until it gets detected by The downfield shift of the 1 H NMR signal of the NH proton, accompanied by the upfield shift of the 15 N NMR signals and the increase of the 1 J(15 N, 1 H) values in the sequence from dimethyl 4-substituted 2,6-dimethyl-1,4-dihydropyridine-3,5-dicarboxylate (1) to 3 and 5, may indicate the shortening of the N-H bond length upon hydrogen bond

1,4-Dihydropyridine (DHP), an important class of calcium antagonist, inhibits the influx of extracellular Ca +2 through L-type voltage-dependent calcium channels. Three-dimensional (3D) structure of calcium channel as a receptor for 1,4-dihydropyridine is a step in understanding its mode of action. Protein structure prediction and modeling tools are becoming integral parts of the standard
Facile one pot synthesis of 1, 4 dihydropyridine Biological Profile: 1, 4-Dihydropyridines are of considerable interest and are well-known compounds because of their pharmaceutical properties. In the human body, compounds are generally oxidized to their corresponding pyridine derivatives, which become biologically inactive.
1,4-dihydropyridine is the most feasible heterocyclic ring with various substitutions at several positions. This molecule binds to the L-type calcium channel and act as a multifunctional lead
the present inventors, as the result of screening of novel compounds having a hypotensive effect, have found that the novel 1,4-dihydropyridine compound of the general formula (i) and the
1. The 1,4-dihydropyridine nucleus serves as the scaffold for important cardiovascular drugs-calcium antagonists-including nifedipine, nitrendipine, amlodipine, and nisoldipine, which exert their antihypertensive and antianginal actions through
1,4-Dihydropyrazine. Molecular Formula CHN. Average mass 82.104 Da. Monoisotopic mass 82.053101 Da. ChemSpider ID 127795.
Dihydropyridines are privileged heterocyclic ring systems because of their broad and significant pharmacological properties and they are also analogues of NADH coenzymes. 1,4-Dihydropyridine derivatives have applications as calcium channel blockers for the treatment of cardiovascular diseases including hypertension.
