Abstract

We studied the effect of aclacinomycin on human erythrocyte membrane enzymes. Aclacinomycin inhibited ATPase, including Na-K-dependent ATPase, ouabain insensitive ATPase and Ca-ATPase. However acetylcholinesterase was not inhibited by aclacinomycin. The ATPase activities were not inhibited by aclacinomycin if ascorbate was added to the incubation mixture. However other reducing agents, alpha-tocopherol, superoxide dismutase and catalase had no effect on ATPase activity. Ascorbate may protect membrane proteins and lipids from peroxidate damage.

摘要

我们研究了阿克拉霉素对人红细胞膜酶的作用。阿克拉霉素抑制ATP酶,包括钠钾依赖性ATP酶、哇巴因不敏感ATP酶和钙ATP酶。然而,乙酰胆碱酯酶未被阿克拉霉素抑制。如果在孵育混合物中加入抗坏血酸,阿克拉霉素不会抑制ATP酶活性。然而,其他还原剂,如α-生育酚、超氧化物歧化酶和过氧化氢酶对ATP酶活性没有影响。抗坏血酸可能保护膜蛋白和脂质免受过氧化损伤。
