electrically evoked contraction of the guinea-pig jejunum). It appeared that by comparison of homologous pairs the thiazolo derivatives have slightly higher activity than their oxazolo analogues. The most potent compound of these series is the 1-(2-thiazolo[4,5-c]pyridine)-4-n-propylpiperazine (3c) with pA2 = 7.25 (its oxazole analogue (4g) showed pA2 = 6.9). The structure-activity relationships for compounds
