Abstract :
Zerumbone ring-opening derivative, 4 (10E/10Z = 3/2), inhibited autophosphorylation of the essential histidine–kinase YycG existing in Bacillus subtilis constituting a two-component system (TCS). Generation of 4E-form could be regulated chemically using the difference from the ring-opening reactivity of the precursor forming of 4 and pure 4E was isolated. The stereoisomer, 4E, showed main inhibition activity of autophosphorylation of YycG (IC50 = 63.5 μM).
