In the continuing search for selective alpha(1)-adrenoceptor (AR) antagonists, new alkoxyarylpiperazinylalkylpyridazinone derivatives were designed and synthesized. The new compounds were tested for their affinity toward alpha(1)-AR, alpha(2)-AR and 5-HT(1A) receptors. The ability of these compounds to inhibit the serotonin transporters (SERT) was also determined. The pharmacological data confirm that
在继续寻找选择性的α(1)-肾上腺素能受体(AR)拮抗剂时,设计并合成了新的烷氧基芳基哌嗪基烷基吡啶并嗪酮衍生物。测试了新化合物对α(1)-AR,α(2)-AR和5-HT(1A)受体的亲和力。还确定了这些化合物抑制血清素转运蛋白(SERT)的能力。药理学数据证实,增加芳基哌嗪部分的苯环上的邻烷氧基取代基的大小,可使化合物对α(1)-AR的亲和力增强。异丙氧基,评估的最大基团,导致了最佳的alpha(1)-AR亲和力。相反,在邻烷氧基-苯基哌嗪片段内具有酰胺基的化合物对所研究的受体表现出低亲和力。
