Abstract
式(I)化合物是有效的和选择性的人5-HT2A拮抗剂,可用于治疗多种CNS的不良病症。
Description
本发明涉及一组作用于血清素受体(还称为5-羟色胺或5-HT受体)的磺酰基衍生物。更具体地,本发明涉及芳基磺酰基萘类及其衍生物。这些化合物是有效的和选择性的人5-HT2A拮抗剂,并且因此可用作药物,特别是治疗和/或预防中枢神经系统的不良病症,包括睡眠障碍如失眠,精神障碍如精神分裂症和障碍如焦虑症。
与其它人受体如D2、5HT2C和IKr受体相比,本发明的化合物特别地显示出更有效地与人5-HT2A受体结合。因此与在这些受体间的亲和力无差别的化合物相比,本发明的化合物有望显示更少的副作用。特别是这些化合物对IKr受体具有较小的作用,并且具有不同于副作用如强心作用的期望的作用。
由于其有效的人5-HT2A受体拮抗活性,本发明的化合物在治疗包括以下的神经病症方面是有效的:睡眠障碍如失眠,精神障碍如精神分裂症以及抑郁症,焦虑症,惊恐性障碍,强制性障碍,疼痛,饮食障碍如神经性厌食症,以及与麻醉剂如LSD或MDMA相关的依赖性或急性毒性;此外,本发明的化合物在控制与服用安定剂有关的锥体外系症状也是有益的。进一步地,它们可有效地降低眼内压(由此治疗青光眼),并且还可有效地治疗绝经期症状,特别是热潮红(见Waldinger等,Maturitas,2000,36,165-8)。
各类含有特别是磺酰基部分的化合物已公开于WO2005/047246、WO2004/101518、WO01/74797、WO00/43362、WO96/35666、EP-A-0261688、EP-0304888,以及US专利4,218,455和4,128,552,DE-A-3901735和Fletcher等,J.Med.Chem.,2002,45,492-503。然而,这些出版物中未公开或暗示本发明提供的特别的化合物类。
根据本发明的化合物是有效的和选择性的5-HT2A受体拮抗剂,其适当地具有100nM或更小的人5-HT2A受体亲和力(Ki),特别是50nM或更小,优选10nM或更小。与人多巴胺D2受体和/或人IKr和/或5HT2C受体相比,本发明的化合物对人5-HT2A受体具有至少10倍的选择性亲和力,适当地至少20倍的选择性亲和力,特别是至少50倍的选择性亲和力。优选与人5HT2C受体相比具有至少100倍选择性的化合物。

该过程还可以用于制备适当地取代的式I化合物的前体化合物,如Ar2-Q1和Ar2-Q4。

当上述用于本发明的制备化合物的过程产生立体异构体的混合物时,这些异构体可以通过常规技术如制备色谱而分离。所述化合物可以制备成消旋体形式,或者单一的对映异构体可以通过对映体特异性的合成或分离而制备。通过标准技术如制备型HPLC,或者通过与旋光酸如二-p-甲苯酰基-D-酒石酸和/或二-p-甲苯酰基-L-酒石酸成盐而形成非对映体配对物,接着分步结晶和游离碱的再生,所述化合物可以例如拆分成它们的各组份对映异构体。通过生成非对映异构体的酯类或酰胺类,接着色谱分离并除去手性助剂,所述化合物还可以被拆分。
上述任意合成顺序中,保护分子上任意的敏感或活性基团是必要的和/或期望的。这可以通过常规的保护基团的方法而完成,如Protective Groups in Organic Chemistry,ed.J.F.W.McOmie,PlenumPress,1973和T.W.Greene & P.G.M.Wuts,Protective Groups inOrganic Synthesis,John Wiley & Sons,1991中所描述的。在合适的后续阶段使用本领域已知的方法可以将保护基团除去。
