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).
