Thiazolylidene-ketonitriles are efficient inhibitors of electron transport in reaction centers from photosynthetic bacteria.
Thiazolylidene-ketonitriles are efficient inhibitors of photosynthetic electron flow in reaction centers from either Rhodobacter sphaeroides or Rhodobacter capsulatus. Some compounds of this class exhibit a higher inhibitor potency in the bacterial system as compared to photosystem II. Up to now, photosystem II inhibitors were generally less active in photosynthetic bacteria. An azido-thiazolylidene-ketonitrile upon illumination almost exclusively tags the L-subunit in the bacterial reaction center.
