    Imidazo[1,2-c]quinazolines with lipid peroxidation inhibitory effect
    摘要:
    A series of imidazo[1,2-c]quinazolines of different lipophilic character was prepared. According to their antioxidant (cyclic voltammetry) properties they all should be potent inhibitors of lipid peroxidation. Under the given circumstances (NADPH-induced lipid peroxidation in rat brain microsomes and Fe(2+)-induced lipid peroxidation in rat brain homogenate), however, their lipid peroxidation inhibitory activity was strongly dependent on their lipophilicity.
