摘　　要：Physiological changes in the photosynthesis, respiration and cell division of Chlamydomonas reinhardtii, a freshwater green alga, in response to adenine nucleotides were investigated. In advance of this investigation, two adenine nucleotides, di(2'-O-methyl)-cyclic bis(3'-5')diadenylic acid (1) and its N-benzoyl-protected analog 2 were synthesized from the commercially available adenosine phosphoramidite. The respective analogs significantly promoted the cell division (cell number) of C. reinhardtii strains 137c mt+ and BR mt+. Moreover, they significantly enhanced the O2 evolution (photosynthesis) and O2 uptake (respiration) of both strains. c-di-AMP analogs seem to play an effective role as a physiological activator in planta.Physiological changes in the photosynthesis, respiration and cell division of Chlamydomonas reinhardtii, a freshwater green alga, in response to adenine nucleotides were investigated.
