Abstract
This disclosure describes novel 15-deoxy-16-hydroxy-16- substituted prostanoic acids and congeners thereof having utility as bronchodilators as hypotensive agents, and as agents for the control of excessive gastric secretion, and particularly, alkyl esters, such as the methyl ester, of such acids.
