title: [4-[Benzyl-(2-dimethylaminoethyl)amino]pyrimidine compounds with selective antagonistic activity against H1-histamine receptors].
abstract: This paper describes the synthesis of 2- and 4-[benzyl-(2-dimethylaminoethyl)amino]pyrimidine compounds and their antihistaminic properties studied on isolated guinea-pig ileum. Calculated pA2 values show that the antihistaminic activity of 4-[p.methoxybenzyl-(2-dimethylaminoethyl)amino]pyrimidine is specific and potent (8-10 times higher than that of thonzylamine).
