Synthesis of fluorescent molecular probes specific for the receptor of blepharismone, a mating-inducing pheromone of the ciliate Blepharisma japonicum

Abstract: Blepharismone (gamone 2) is a mating-inducing pheromone of the ciliate Blepharisma japonicum. N-Pyrenylbutyryl-blepharismone and N-biphenylacetyl-blepharismone, which are fluorescent derivatives of blepharismone, were synthesized as molecular probes for the gamone 2 receptor. Further, we proved that they have inhibitory activities against the blepharismone-induced monotypic pairing of B. japonicum. [Copyright &y& Elsevier]
