The synthesis and pharmacological analyses of a number of furo[2,3-b]quinolin-4-amine, and pyrrolo[2,3-b]quinolin-4-amine derivatives are reported. Thus, we synthesized diversely substituted tacrine analogues 1–11 and 12–16 by Friedländer-type reaction of readily available o-amino(furano/pyrrolo)nitriles with suitable and selected cycloalkanones. The biological evaluation of furanotacrines 1–11 and
报道了许多呋喃并[2,3 - b ]喹啉-4-胺和吡咯并[2,3 - b ]喹啉-4-胺衍生物的合成和药理学分析。因此,我们合成了不同地取代的他克林的类似物1 - 11和12 - 16由容易获得的德兰德型反应ø -氨基(呋喃/吡咯)与合适的和选定的环烷酮腈。的生物学评价furanotacrines 1 - 11和pyrrolotacrine 13表明,这些都是很好的,在微摩尔范围内,和丁酰胆碱酯酶的高度选择性抑制剂。在呋喃诺那林中组中,最有趣的抑制剂是2-(对甲苯基)-5,6,7,8-四氢呋喃[2,3- b ]喹啉-4-胺(3)[IC 50(eqBuChE)= 2.9±0.4μM ; IC 50(hBuChE)= 119±15μM]。相反,吡咯烷酮 12和14被证明对两种胆碱酯酶具有中等等价性,分别是1,2-二苯基-5,6,7,8-四氢-1 H-吡咯并[2,3 - b ]喹啉-4-胺(12)。对两种酶的抑制作用最强[IC
