Novel pyridopyrimidine derivatives as inhibitors of stable toxin a (STa) induced cGMP synthesis

Bioorg Med Chem Lett. 2009 Jun 1;19(11):3067-71. doi: 10.1016/j.bmcl.2009.04.024. Epub 2009 Apr 12.

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.
