Background: Calcium channel blockers have an important role in treatment of various cardiovascular diseases including hypertension, angina pectoris and cardiac arrhythmias, so study of cardiovascular effects of derivatives of these drugs are useful. Nifedipine is one of these drugs that used widely to treat hypertension and other cardiovascular diseases. The aim of the present study was to eval...
β-site amyloid precursor protein cleaving enzyme (BACE-1) is a validated target for Alzheimer therapy due to its distinctive role in pathogenesis of AD. In the present contribution, a series of new 3,5-bis-N-(aryl/heteroaryl) carbamoyl-4-aryl-1,4-dihydropyridine structures were synthesized as BACE-1 inhibitors (6a-6n). In vitro BACE-1 inhibitory activities were determined by enzymatic fluoresce...
Current researches have showed that N3, N5-diaryl-2, 6-dimethyl -1, 4-dihydropyrine-3, 5- dicarboxamide analogues demonstrate notable anti-tubercular activity. In this study, Hantzsch condensation was used to design and synthesize new analogues of dihydropyridine (DHP). Different diary carboxamides were inserted at positions 3 and 5 of the DHP ring. 4(5)-chloro-2-ethyl-5(4)-imidazolyl moiety wa...
The effect of temperature and air humidity on the stability of 7 derivatives of 1,4-dihydropyridine (nifedipine, nisoldipine, nitrendipine, nimodipine, nicardipine, felodipine and amlodipine) in solid state has been studied by accelerated testing. Quantitative analysis of the compounds studied was made by UV spectrophotometry, identification of the thermodegradation products and reference to th...
The combination of 1-benzyl-1,4-dihydropyridines with the strong Lewis acid, B(C6F5)3, generates a stable pyridinium borohydride species in high yields (94%) in as little as 10 min. This use of biologically inspired hydride sources further builds on the recent work of new hydride donors in the formation of borohydrides. When functionalizing the dihydropyridine with an amide or carboxylic acid m...
