Abstract
The present invention relates to a composition of matter comprising novel prostaglandin E2 receptor antagonists, and their use in treatments for regulating the fluid filtration in the kidney, preventing bone mineral loss in osteoporosis and dental disease and additionally, closure of ductus arteriosus (DA) in premature infants or fetal animals. Additionally, the compositions include linear peptides, peptide analogs, and peptidomimetics.
