Two novel classes of diphenyloxazole and Ndelta-Z-ornithine derivatives as highly potent and selective EP(4) antagonists have been discovered. The optimized diphenyloxzole 8 and Ndelta-Z-ornithine 11 effectively competed with [(3)H]PGE(2) binding to human recombinant EP(4), with K(i) values of 0.30 nM and 0.91 nM, respectively, and were selective for all members of the human prostanoidreceptor family
