Biological Activity
Carfentrazone-ethyl (1-10000 nM; 15 min) potently inhibits protoporphyrinogen oxidase in etioplasts of soybean, with an I50 value of 18 nM[1].
Carfentrazone-ethyl (100 nM; 30 min) competes with [14C]aciñuorfen for binding to soybean etioplast protoporphyrinogen oxidase, with a binding constant of 258 nM[1].
