  摘要：

  通过两种方法从乙酰苯磺酰胺类化合物（II）制备了新型α和β肾上腺素能阻断剂苯磺酰胺衍生物（Ia-z）。对这些化合物进行了α和β阻断活性测试，并讨论了它们的结构-活性关系。所有目标化合物都有两个不对称中心，因此由两种非对映异构体组成。5-[1-羟基-2-[3-(2-甲氧基苯基)-1-甲基丙氨基]乙基]-2-甲基苯磺酰胺（Ir）和 5-[1-羟基-2-[2-2-(2-甲氧基苯氧基)-1-甲基乙基氨基]乙基]-2-甲基苯磺酰胺（Iu）显示了强效的α和β-阻断活性，并分别被分离成两种非对映异构体（Ir-A 和 Ir-B 以及 Iu-A 和 Iu-B）。结果发现，一种异构体主要具有 β-阻断活性，而另一种异构体主要具有 α-阻断活性。此外，研究人员还对几种具有较强α和β阻断活性的化合物进行了研究，以观察它们在有意识的自发性高血压大鼠体内的降压活性。在测试的化合物中，Ir 和 Iu 的活性最高，它们比拉贝洛尔更强。Ir和Iu化合物作为强效降压药可能具有实用价值。

  A series of beta-chloroethylamines 5-18, structurally related to the irreversible alpha(1)-adrenoceptor antagonist phenoxy-benzamine [PB, N-benzyl-N-(2-chloroethyl)-N-(1-methyl-2-phenoxyethyl)amine hydrochloride, 1] and the competitive antagonist WB4101 [N-(2,3-dihydro-1,4-benzodioxin-2-ylmethyl)-N-[2-(2,6-dimethoxyphenoxy)ethyl]amine hydrochloride, 2], were synthesized and evaluated for their activity at alpha-adrenoceptors of the epididymal and the prostatic portion of young CD rat vas deferens. All compounds displayed irreversible antagonist activity. Most of them showed similar antagonism at both alpha(1)- and alpha(2)-adrenoceptors, whereas compounds 13 and 18, lacking substituents on both the phenoxy group and the oxyamino carbon chain, displayed a moderate alpha(1)-adrenoceptor selectivity (10-35 times), which was comparable to that of PB. Compounds 14 and 15, belonging to the benzyl series and bearing, respectively, a 2-ethoxyphenoxy and a 2-i-propoxyphenoxy moiety, were the most potent alpha(1)-adrenoceptor antagonists with an affinity value similar to that Of PB (pIC(50) values of 7.17 and 7.06 versus 7.27). Interestingly, several compounds were able to distinguish two alpha(1)-adrenoceptor subtypes in the epididymal tissue, as revealed by the discontinuity of their inhibition curves. A mean ratio of 24:76 for these alpha(1)-adrenoceptors was determined from compounds 8-10, 12, and 15-17. Furthermore, compounds 9, 10, 12, 16a, and 16b showed higher affinity towards the minor population of receptors, whereas compounds 8, 15, and 17 preferentially inhibited the major population of alpha(1)-adrenoceptors. In addition, selected pharmacological experiments demonstrated the complementary antagonism of the two series of compounds and their different, preferential affinity for one of the two alpha(1)-adrenoceptor subtypes. In conclusion, we found beta-chloroethylamines that demonstrate a multiplicity of alpha(1)-adrenoceptors in the epididymal portion of young CD rat vas deferens and, as a consequence, they are possible useful tools for alpha(1)-adrenoceptor characterization.

  New α-and β-adrenergic blockers, benzenesulfonamide derivatives (Ia-z), were prepared from acetylbenzenesulfonamides (II) by two methods. These compounds were tested for α-and β-blocking activities and their structure-activity relationships are discussed. All the target compounds have two asymmetric centers and therefore consist of two diastereomers. 5-[1-Hydroxy-2-[3-(2-methoxyphenyl)-1-methylpropylamino]ethyl]-2-methylbenzenesulfonamide (Ir) and 5-[1-hydroxy-2-[2-2-(2-methoxyphenoxy)-1-methylethylamino] ethyl]-2-methylbenzenesulfonamide (Iu) showed potent α-and β-blocking activities and they were each separated into two diastereomers (Ir-A and Ir-B, and Iu-A and Iu-B). It was found that one isomer had mainly β-blocking activity and the other isomer had mainly α-blocking activity. In addition, several compounds showing relatively strong α-and β-blocking activities were also examined for antihypertensive activity in conscious spontaneously hypertensive rats. Among the compounds tested, Ir and Iu were the most active, and they were more potent than labetalol. Compounds Ir and Iu may be of practical use as potent antihypertensive agents.
