ABSTRACT:
The present invention relates in part to novel amido, cycloamido, carbonylamido and sulfonylamido derivatives and p-substituted phenyl esters of 9-deoxy-9-methylene-PGF-type compounds. These novel amides produce surprisingly prolonged oral activity as pharmacological agents, as compared to the previously known 9-deoxy-9-methylene-PGF-type compounds.
Further, the novel p-substituted phenyl esters provide more stable pharmaceutical formulations as compared to known 9-deoxy-9-methylene-PGF-type esters.
Additionally, a novel series of 16-phenyl-9-deoxy-9-methylene-PGF-type compounds in free acid, ester, C-1 alcohol, and C-1 amine form is provided. Such compounds exhibit characteristic prostaglandin-type pharmacological actions.
