the 3‐amino‐1‐propanol moiety common to the many previously described non‐imidazole H3 ligands. Detailed structure‐activity studies revealed that 1‐(2‐benzofuranylmethyl)‐ 5c (pA2 = 8.47 ± 0.05) and 1‐(3‐benzofuranylmethyl)‐4‐[5‐(N‐methyl‐N‐propyl)pentyloxy]piperidine 5d (pA2 = 8.15 ± 0.07) exhibit high potency for the H3 histamine receptor. In addition, the potency of selected 1‐[(N‐substituted‐N‐

H3 receptor antagonists – the electrically evoked contraction of the guinea‐pig jejunum. The histaminergic H1 antagonism of selected compounds 9b1, 9b2, and 9b4–9b6 was established on the isolated guinea‐pig ileum by conventional methods; the pA2 values were compared with the potency of pyrilamine. The compounds did not show any H1 antagonistic activity (pA2 < 4; for pyrilamine pA2 = 9.53).
