New prenylamine-analogues: investigations of their influence on calcium-dependent biological systems
摘要:
Chemically, prenylamine belongs to the diphenylalkylamine class. Compounds of this class are calcium antagonists with a broad spectrum of activities due to their influence on both extracellular and intracellular sites. In the present study the calcium antagonistic profile of a recently developed new series of prenylamine analogues has been investigated using different in vitro systems. The inhibiting concentrations for the most active compound are almost-equal-to 1.5 muM; several derivatives are inactive up to a concentration of 10 muM. Structural modifications towards an increase of lipophilicity make these molecules interact (inhibition) with the intracellular calcium-binding protein calmodulin; for the series no correlation between calcium-blocking and calmodulin antagonistic effects has been found.
New prenylamine analogues: synthesis and Ca2+-entry blocking activity
摘要:
The synthesis of a series of diphenylalkylamine derivatives related to prenylamine is reported. The amphetamine group in the prenylamine structure was replaced by other moieties. In addition to substitutions in the aromatic rings, heteroatoms such as sulphur and oxygen were introduced in the chain. The calcium-entry blocking activity was assayed in binding experiments on a guinea-pig brain membrane preparation by displacing [H-3]-nitrendipine.
