Misoprostol is a widely sold analog of prostaglandin E1 (PGE1) that has potent but relatively non-selective agonist activity with respect to the prostanoid EP receptor subgroup(1). Misoprostol has been used therapeutically for many years in humans for treatment of gastric ulcer disease under the Searle tradename Cytotec(2). 8-iso Misoprostol is one of several impurities which are possible in the production of bulk commercial preparations of misoprostol. It is also somewhat difficult to distinguish from other impurities such as 11β-misoprostol(3). The pharmacology and EP receptor binding affinity for 8-iso misoprostol has not been published.
