The present invention provides a broad-spectrum, long-lasting, and non-toxic combination of synthetic immunostimulatory agents, which are useful for activating the immune system of a mammal and treating diseases such as cancer and autoimmune disease. These agents include TLR-ligands and ligand analogs which induce interferon production, in combination with inhibitors of inosine monophosphate dehydrogenase (IMPDH), that further enhance the induction of interferon production.

The synthesis of a guanosine analog in the pyrido[2,3-d]pyrimidine ring system has been accomplished by glycosylation of the preformed aromatic heterocyclic base, which was prepared in 2 steps by condensation of methyl acrylate with guanidine carbonate and methyl cyanoacetate in the presence of sodium methoxide, followed by dehydrogenation. The analog was evaluated in vitro for its ability to modulate
