this property. The most active derivative, N-[3-[(4-amino-6, 7-dimethoxy-2-quinazolinyl)methylamino]propyl]tetrahydro-2-furancarbo xamide hydrochloride, alfuzosin (12), showed high selectivity for peripheral alpha 1-postjunctional adrenoceptors. At equiactive antihypertensive doses, its effect on the pressor response to postural changes in conscious dog was less marked than that shown by prazosin. In the
合成了一系列的N2-[(酰基氨基)烷基] -6,7-二甲氧基-2,4-喹唑啉二胺作为潜在的α1-肾上腺素受体拮抗剂。当以10 mg / kg po自发性高血压大鼠给药时,许多丙烷二胺衍生物显示出良好的降压活性,而乙二胺衍生物尽管在结构上与哌唑嗪密切相关,却缺乏该特性。活性最高的衍生物N- [3-[(4-氨基-6,7-二甲氧基-2-喹唑啉基)甲基氨基]丙基]四氢-2-呋喃甲酰胺x盐酸盐阿夫唑嗪(12)对外围α1具有很高的选择性。 -结后肾上腺素受体。在等剂量的降压剂量下,其对清醒犬体位变化的升压反应的作用不如哌唑嗪所显示。根据这些结果,
