Abstract

Bafilomycin A₁, a potent selective inhibitor of vacuolar H⁺-ATPase, inhibited the growth of a variety of cultured cells dose-dependently, including golden hamster embryo and NIH-3T3 fibroblasts, whether or not they were transformed, and PC12 and HeLa cells. The concentration of bafilomycin A₁ for 50% inhibition of cell growth ranged from 10 to 50 n M. The dose response was nearly parallel with that of the bafilomycin A₁-induced lysosomal pH increase. The degree of pH increase for growth inhibition produced by bafilomycin A₁ was similar to that produced by NH₄Cl in which little difference was recognized in effect among cell types.
