    Synthesis and Evaluation of Reducing Capacity and Calcium Channel Blocking Activity of Novel 3,5-Dipropargylcarbonyl-Substituted 1,4-Dihydropyridines*

    Novel pyridinium salts based on 4-(3-pyridyl)-3,5-dipropargylcarbonyl-1,4-dihydropyridine were obtained by quaternization of pyridine moiety with different alkyl halides. The reducing capacity of the synthesiz...

    Bilayer properties of giant magnetic liposomes formed by cationic pyridine amphiphile and probed by active deformation under magnetic forces

    We synthesize giant magnetic liposomes by a reverse-phase evaporation method (REV) using a new self-assembling Cationic Pyridine Amphiphile (CPA) derived from 1,4-dihydropyridine as liposome-forming agent and ...

    Effect of the solvent nature on the course of quaternization of 3,5-diethoxycarbonyl-2,6-dimethyl-4-(3-pyridyl)-1,4-dihydropyridine

    The effect of the solvent nature and temperature on the quaternization of 3,5-diethoxycarbonyl-2,6-di- methyl-4-(3-pyridyl)-1,4-dihydropyridine by lipophilic alkyl bromides has been investigated. By comparison...
