similar pharmacophore, dinapsoline has pharmacological similarities to dihydrexidine ((1); (+/-)-trans-10,11-dihydroxy-5,6,6a,7,8,12b-hexahydrobenzo[a]phenanthridine), the first high affinity full D(1) agonist. Small alkyl substitutions on the dihydrexidine backbone are known to alter markedly the D(1):D(2) selectivity of dihydrexidine, and it was of interest to determine whether similar SAR exists within
Dinapsoline((2);(+/-)-dihydroxy-2,3,7,11b-tetrahydro-1H-naphth [1,2,3-de] isoquinoline)是完整的D(1)多巴胺激动剂显着的D(2)受体亲和力。基于相似的药效基团,地那普林与二氢己定((1);(+/-)-trans-10,11-dihydroxy-5,6,6a,7,8,12b-六氢苯并[a]菲啶)具有药理相似性,第一个高亲和力全D(1)激动剂。已知二氢己定骨架上的小烷基取代会显着改变二氢己定的D(1):D(2)选择性,因此确定地那普林系列中是否存在相似的SAR引起人们的兴趣。该报告描述了地那辛的六种类似物的合成和药理学评估:N-烯丙基-(3); Nn-丙基-(4); 6-甲基-(5); 4-甲基-(6); 4-甲基-N-烯丙基-(7); 和4-甲基-Nn-丙基-二氮杂萘啉(8)。正如从对二氢己啶骨架的早期研
