Abstract
Conformationally constrained analogues of KN62 containing 1,2,3,4-tetrahydr o-7-hydroxyisoquinoline-3-carboxylic acid with S configuration in position 3 were synthesized and their antagonist activities were tested on human mac rophage cells. While KN62 is a potent antagonist of the P2X(7) receptor, th ese analogues were inactive as antagonists and only one compound showed app reciable activity as P2X(7) antagonist, which was 30 times weaker than that reported for KN62.
