The 4-hydroxycinnamate decarboxylase (4-HCD)-inducing activity of several substrate analogs toward Klebsiella oxytoca was investigated. Four E-cinnamate-class compounds, E-4-hydroxycinnamic acid (1), caffeic acid (2), ferulic acid (3) and E-2,4-dihydroxycinnamic acid (4), all of which were accepted as substrates, all of which
