title: Studies on griseolic acid derivatives. I. Synthesis of substituted derivatives of griseolic acid at the N1, C6, C2' or C7' position and their biological activities.
abstract: Griseolic acid derivatives having a different substituent at the N1,C6,C2' or C7' position of the natural product were synthesized and their structure activity relationship to cyclic nucleotide phosphodiesterase inhibitory activity was investigated.
