title: Synthesis and prostaglandin-like activity of 2-(trans-3-hydroxy-1-octenyl)-3-indoleheptanoic acid.
abstract: The synthesis of 2-(trans-3-hydroxy-1-octenyl)-3-indoleheptanoic acid (1) is described. The title compound appeared to show a weak prostaglandin-like activity in two different systems. It contracted rat stomach fundus strips and guinea-pig ileum preparations only at concentrations about 10(3)- and 10(2)-fold higher, respectively, than PGE1. Moreover, it stimulated adenylate cyclase from rat liver plasma membrane, but the relative potency was 4--5 X 10(2)-fold lower than the natural compound. The title compound showed also a certain degree of PGE1 antagonism.
