  Synthesis and α1-antagonist activity of new prazosin- and benextramine-related tetraamine disulfides

  摘要：

  Tetraamine disulfides 1-10 were designed by combining the structural features of benextramine, an irreversible alpha(1)/alpha(2)-adrenoceptor antagonist, and prazosin, a selective competitive alpha(1)-antagonist. Their biological profile was assessed by functional and binding assays. In rat vas deferens functional experiments, tetraamine disulfides 1-10 displayed a marked selectivity at alpha(1)-adrenoceptors. Furthermore, they acted as competitive antagonists at alpha(1)-adrenoceptors and weak noncompetitive (irreversible) antagonists at alpha(2)-adrenoceptors. In binding assays, performed at alpha(1)-adrenoceptors of rat liver (alpha 1B) and submaxillary gland (alpha(1A), compound 5 showed an 11-fold selectivity for alpha(1B)-adrenoceptors in contrast to both prazosin and benextramine, which were not selective or selective for the alpha(1A)-subtype respectively.
