The present invention relates to compounds that bind to and modulate the activity of neuronal nicotinic acetylcholine receptors (NNRs), to processes for preparing these compounds, to pharmaceutical compositions containing these compounds, and to methods of using these compounds for treating a wide variety of conditions and disorders, including those associated with dysfunction of the central nervous system (CNS). The present invention includes compounds which bind with high affinity to NNRs of either the α4β2 subtype, or the α6-containing subtype, or both NNR subtypes. Formula (I), wherein: each m is identical and is 0 or 1; each n is identical and is 0 or 1; when each m is 0, then each n is 1; when each m is 1, then each n is 0; R1 is -C(O)-R3, -C(O)O-R3, -C(O)NH-R3, -C(O)-(CH2)q-X-R3, -C(O)O-(CH2)q-X-R3, or -C(O)NH-(CH2)q-X-R3; q is 1, 2, 3, 4, 5, or 6; X is -0-, -S-, -NH-, or -NHC(O)-; R2 is H or alkyl; R3 is alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkenyl, cycloalkynyl, aryl, heteroaryl, or heterocyclic.
本发明涉及结合并调节神经元尼古丁型乙酰胆碱受体(NNRs)活性的化合物,以及制备这些化合物的过程,含有这些化合物的药物组合物,以及利用这些化合物治疗各种疾病和疾患的方法,包括与中枢神经系统(CNS)功能障碍相关的疾病。本发明涵盖与NNRs的α4β2亚型、α6含量亚型或两者NNR亚型中的一个结合亲和力较高的化合物。公式(I),其中:每个m相同且为0或1;每个n相同且为0或1;当每个m为0时,每个n为1;当每个m为1时,每个n为0;R1为-C(O)-R3、-C(O)O-R3、-C(O)NH-R3、-C(O)-(CH2)q-X-R3、-C(O)O-(CH2)q-X-R3或-C(O)NH-(CH2)q-X-R3;q为1、2、3、4、5或6;X为-0-、-S-、-NH-或-NHC(O)-;R2为H或烷基;R3为烷基、烯基、炔基、环烷基、环烯基、环炔基、芳基、杂芳基或杂环烷基。
