[Thiophene as a structural element of physiologically active substances. 20. Thiophene analogs of the leukotriene D4 antagonist Ro 23-3544]
Abstract
The synthesis of 6-Acetyl-7-[[5-(5-acetyl-4-hydroxy-3-propyl-2-thienyl- oxy)pentyl]oxy]-3,4-dihydro-2H-1-benzopyran-2-carboxylic acid (1), a thiophene analogue of the leukotriene antagonist Ro 23-3544, is described. Compound 1 shows almost no effect on leukotriene D4 induced broncho-constriction on anesthesized guinea pigs.
