reported N alpha- and N pi-benzylhistamines, were tested for agonist and antagonist activity at both H1 and H2 receptors. The results obtained indicate that introduction of a benzyl group into the histamine molecule causes a marked reduction in H1- or H2-agonist activity, and none of the compounds showed consistent antagonist activity. Evidently, the sterically demanding benzyl substituent is not easily
