Abstract
A series of pyridopyrimidine derivatives were synthesized and evaluated for their ability to inhibit cyclic nucleotide synthesis in the presence of stable toxin a of Escherichia coli. The structure activity relationships around the basic core structure were examined and examples with better activity and potentially better pharmacological properties are presented.
