The effect of eight cyclic purine and cyclic pyrimidine nucleotides on DNA synthesis on mouse lymphoid cells was investigated. Two out of eight compounds tested, namely 2', 3'-cyclic guanosine monophosphate (2', 3'-cGMP) as well as 3', 5'-cyclic guanosine monophosphate (3', 5'-cGMP), stimulate thymidine incorporation in all types of lymphocytes tested. The stimulatory activity of the cyclic guanosine nucleotides as well as the effects of lectins could be antagonized by 3', 5'-cyclic adenosine monophosphate (3', 5'-cAMP). 2', 3'-cGMP seems to stimulate preferentially mature T-cells while 3', 5'-cGMP preferentially acts on B-cells.
