16-phenoxy PGF2α is a metabolically stable analog of PGF2α. It binds to the FP receptor on ovine luteal cells with much greater affinity (440%) than PGF2α.
16-phenoxy tetranor Prostaglandin F2α (16-phenoxy tetranor PGF2α) is a metabolically stable analog of PGF2α. It binds to the FP receptor on ovine luteal cells with much greater affinity (440%) than PGF2α.
