CAY10408 is a free acid, 2-series analog of butaprost . It is the less active C-16 epimer compared to the 16(S) isomer, which has the same stereochemistry as butaprost. Butaprost has frequently been used to pharmacologically define the EP receptor expression profile of various animal and human cells and tissues. Since the majority of reports related to butaprost utilize the methyl ester derivative, it may be some time before the precise pharmacology of the free acid compounds, like CAY10408, is reported.
