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