title: [The anti-H1-histaminic and antimuscarinic effect of 2- and 4-[benzyl-(2-dimethylaminoethyl)amino]pyrimidine compounds].
abstract: This paper reports the synthesis of 2- and 4- [benzyl-(2-dimethylaminoethyl)amino]pyrimidine compounds and the evaluation of their inhibitory properties against histamine (H1), acetylcholine and barium chloride, on guinea pig isolated ileum. 4-[p.Methoxybenzyl-(2-dimethylaminoethyl)amino]-2-methoxy-pyrimidine (VIII) is shown to possess H1 receptor antagonist activity, with a potency similar to that observed for Tonzylamine. By contrast, a specific, although weak, antimuscarinic effect is displayed by 4-[benzyl-(2-dimethylaminoethyl)amino]-2-methoxy-5-methylthio-pyrimidine (XII).
