1,4-Dihydropyridines bearing a pharmacophoric fragment of lidoflazine
摘要:
A series of 1,4-dihydropyridines bearing a pharmacophoric fragment of Iidoflazine was synthesized. The compounds were evaluated for inotropic, chronotropic, and calcium antagonist activities. All compounds behave as inotropic and chronotropic agents, except for compounds 4b, 5a, and 5b, which exibit a rather weak calcium antagonism in vascular smooth muscle (like aorta). Compound 5b is about twofold more potent in decreasing both chronotropy and inotropy, while compound 5c is about fivefold more potent in decreasing inotropy than nifedipine. Moreover, compound 5b is the most potent calcium antagonist derivative of the series. Copyright (C) 1996 Elsevier Science Ltd

The present invention provides, among other things, therapeutic compositions and methods that can effectively treat, slow or prevent a neurological disease (e.g., a neurodegenerative disease, e.g., mild cognitive impairment (MCI) or Alzheimer's disease (AD)), in particular, based on therapeutically effective amount of nifedipine, oxidized or nitroso nifedipine derivatives, lactam (e.g., a compound of formula (Ic) or (Ic-i), e.g., NFD- L1), thyroxine (T4), triiodothyronine (T3) and combinations thereof.
As prodrugs series of new sartan-derived molecules were designed, synthesized, and evaluated. Most of the synthesized compounds could decrease blood pressure efficiently in spontaneously hypertensive rats. It could be ratiocinated that the original drugs could be released from the prodrugs exactly at the connecting position catalyzed by the hydrolyzation enzymes. The maximal response of mean blood
