15(S)-15-methyl Prostaglandin E1

15(S)-15-methyl Prostaglandin E1 (15(S)-15-methyl PGE1) is a metabolically stable synthetic analog of PGE1 (Cay-13010). In sharp contrast to the bronchodilatory effects of PGE1, 15(S)-15-methyl PGE1 is a weak constrictor of human respiratory tract smooth muscle.Formal Name: 9-oxo-11alpha,15S-dihydroxy-15-methyl-prost-13E-en-1-oic acid.
