Bafilomycin A1是一种选择性的空泡H+ ATPases(V-ATPases)抑制剂,I50值为4-400 nmol/mg[1]。
Bafilomycin A1作用于不同类型的膜ATPases,作用于真菌(粗糙脉孢菌)、植物(Z. Mays)和动物(牛肾上腺髓质)的空泡ATPases,I50值分别为400 nmol/mg、4 nmol/mg 和50 nmol/mg。此外,bafilomycin A1对空泡ATPases的抑制活性通过检测其对H+泵活性的影响而进一步确定。H+的易位被10 nM bafilomycin A1完全抑制[1]。其它的研究表明,bafilomycin A1强烈抑制破骨细胞的坑形成活性。通过免疫电镜观察bafilomycin A1处理或非处理破骨细胞中V-ATPase的亚细胞定位。这些结果表明,bafilomycin A1破坏V-ATPase在皱褶缘的定位,导致牙质表面酸化的缺乏[2]。注:I50值是指抑制每mg蛋白中50%的ATPase活性所需要的bafilomycin A1的umol量。
