Abstract
一种式I化合物或其可药用盐的制备方法;其中X、Y、a、b、c、d、R1、R2、R3和R5如上所述定义,可用于治疗炎症和其他免疫疾病。
Description
发明背景
本发明涉及新的磺酸衍生物、使用方法和含上述化合物的药物组合物。
本发明的化合物是MIP-1α(CCL3)与其见于炎性细胞和免疫调节细胞(优选白细胞和淋巴细胞)上的受体CCR1结合的有效的选择性抑制剂。CCR1受体有时也称为CC-CKR1受体。这些化合物还抑制MIP-1α(和相关的被证实与CCR1相互作用的趋化因子(例如RANTES(CCL5),MCP-2(CCL8),MCP-3(CCL7),HCC-1(CCL14)和HCC-2(CCL15)))诱导的THP-1细胞和人白细胞的趋化性,并且可能用于治疗或预防自身免疫病(例如类风湿性关节炎、I型糖尿病(新近发病)、狼疮、炎性肠病、视神经炎、牛皮癣、多发性硬化、风湿性多肌痛、眼色素层炎和脉管炎),急性和慢性炎症(例如骨关节炎、成人呼吸窘迫综合征、婴儿呼吸窘迫综合征、缺血再灌注损伤和肾小球肾炎),变应性疾病(例如哮喘和特应性皮炎),与炎症相关的感染(例如病毒性炎症(包括流感和肝炎)和急性感染性多神经炎),慢性支气管炎,异种移植(xeno-transplantation),移植组织排斥(慢性的和急性的),器官排斥(慢性的和急性的),动脉粥样硬化,再狭窄(包括但不限于球囊和/或支架插入后的再狭窄),HIV感染性(infectivity)(共同受体使用(co-receptor usage)),以及肉芽肿性疾病(包括结节病、麻风和结核病)和与某些癌症如多发性骨髓瘤有关的后遗症。此系列化合物还可用于防止癌转移。由于减少了细胞浸润,此系列化合物还可限制在炎症位点产生细胞因子,包括但不限于TNF和IL-1,对与TNF和IL-1相关的疾病有利,其中包括充血性心力衰竭、肺气肿或与此相关的呼吸困难、气肿;HIV-1,HIV-2,HIV-3;巨细胞病毒(CMV),腺病毒,疱疹病毒(带状疱疹和单纯疱疹)。它们还对与感染有关的后遗症有利,例如真菌性脑膜炎、关节组织损伤、增生、形成关节翳和骨吸收、牛皮癣关节炎、肝功能衰竭、细菌性脑膜炎、川崎综合征、心肌梗塞、急性肝功能衰竭、莱姆病、败血症性休克、癌症、外伤和疟疾等,其中所述感染诱发产生有害的炎性细胞因子如TNF。
MIP-1α和RANTES都是可溶性趋化肽(趋化因子),它们是由炎性细胞,特别是CD8+淋巴细胞、多形核白细胞(PMNs)和巨噬细胞产生的,生物化学杂志(
J.Biol.Chem.),
270(30)29671-29675(1995)。这些趋化因子通过诱导关键炎性细胞和免疫调节细胞的迁移和活化而起作用。已在类风湿性关节炎患者的滑液、来自移植患者的慢性排斥组织以及在接触过敏原后的过敏性鼻炎患者的鼻分泌物中发现了升高水平的趋化因子(Teran等,免疫学杂志(
J.Immunol.),1806-1812(1996)),以及Kuna
等,变态反应和临床免疫学杂志(
J.Allergy Clin. Immunol.)321(1994))。通过中和MIP-1α或基因破坏而干扰趋化因子/受体相互作用的抗体已为MIP-1α和RANTES通过限制单核细胞和CD8+淋巴细胞的募集在疾病中所起作用提供了直接证据(Smith
等,免疫学杂志(J.Immunol.),153,4704(1994)和Cook
等,科学(
Science),269,1583(1995))。该资料还证明了CCR1受体拮抗剂会成为对数种基于免疫的疾病的有效治疗。在此所述的化合物是CCR1受体的有效的和选择性的拮抗剂。

碱性的式I化合物能与各种无机和有机酸形成多种不同的盐。尽管这种盐必须是药学上可接受用于动物给药的,但通常在实践中希望先从反应混合物中分离出式I化合物为药学上不可接受的盐,然后通过用碱性试剂处理而简单地将后者转化回为游离碱化合物,随后将该游离碱转化成可药用酸加成盐。本发明的碱化合物的酸加成盐易于通过用基本等当量的选定的无机酸或有机酸在水性溶剂介质或在适宜的有机溶剂如甲醇或乙醇中处理该碱化合物而制备。经过小心地蒸发溶剂后,得到固体盐。
用于制备本发明的碱化合物的可药用酸加成盐的酸是那些形成无毒的酸加成盐的酸,该无毒的酸加成盐即含药理上可接受的阴离子的盐,例如:盐酸盐、氢溴酸盐、氢碘酸盐、硝酸盐、硫酸盐或硫酸氢盐、磷酸盐或酸式磷酸盐、乙酸盐、乳酸盐、柠檬酸盐或酸式柠檬酸盐、酒石酸盐或酒石酸氢盐、琥珀酸盐、马来酸盐、富马酸盐、葡糖酸盐、糖二酸盐、苯甲酸盐、甲磺酸盐和扑酸盐[即1,1’-亚甲基-双-(2-羟基-3-萘甲酸盐)]。
还呈酸性的那些式I化合物能与各种药理上可接受的阳离子形成碱盐。这样的盐的实例包括碱金属盐或碱土金属盐,尤其是钠盐和钾盐。这些盐都是通过常规技术制备的。用作试剂制备本发明的可药用碱盐的化学碱是与本文所述酸性的式I化合物形成无毒的碱盐的那些。这些无毒的碱盐包括得自诸如钠、钾、钙和镁等药理上可接受的阳离子的那些。这些盐可容易地通过下列方法制备:用含所需的药理上可接受的阳离子的水溶液处理相应的酸性化合物,然后优选在减压下将所得的溶液蒸发至干。或者,还可以这样制备:将酸性化合物的低级链烷醇溶液与所需的碱金属醇盐混合在一起,然后按与前述相同的方式将所得的溶液蒸发至干。两种情况都优选应用化学计算量的试剂以保证反应完全和最大产率。
式I化合物及其可药用盐(下文亦合称“活性化合物”)是CCR1受体的有效拮抗剂。该活性化合物用于治疗或预防自身免疫疾病(例如类风湿性关节炎、I型糖尿病(新近发病)、狼疮、炎性肠病,视神经炎,牛皮癣,多发性硬化,风湿性多肌痛、眼色素层炎和脉管炎),急性和慢性炎症(如骨关节炎,成人呼吸窘迫综合征,婴儿呼吸窘迫综合征,缺血再灌注损伤,肾小球肾炎和慢性阻塞性肺病(COPD)),变应性疾病(如哮喘和特应性皮炎),与感染相关的炎症(如病毒性炎症(包括流感,肝炎和急性感染性多神经炎),慢性支气管炎,慢性和急性组织、细胞和实体器官移植排斥(包括异种移植),动脉粥样硬化,再狭窄,HIV感染性(共同受体应用),以及肉芽肿性疾病(包括结节病、麻风和结核病)和与某些癌症如多发性骨髓瘤相关的后遗症。此系列化合物还可用于预防癌转移,以及球囊和/或支架插入后的再狭窄。由于减少了细胞浸润,此系列化合物还可限制在炎症位点产生细胞因子,包括但不限于TNF和IL-1,对与TNF和IL-1有联系的疾病有利,其中包括充血性心力衰竭、肺气肿或与此相关的呼吸困难、气肿;HIV-1,HIV-2,HIV-3;巨细胞病毒(CMV),腺病毒,疱疹病毒(带状疱疹和单纯疱疹)。它们还对与感染有关的后遗症有利,例如真菌性脑膜炎、关节组织损伤、增生、形成关节翳和骨吸收、牛皮癣关节炎、肝功能衰竭、细菌性脑膜炎、川崎综合征、心肌梗塞、急性肝功能衰竭、莱姆病、败血症性休克、癌症、外伤和疟疾等,其中所述感染诱发产生有害的炎性细胞因子如TNF。
本发明的化合物的活性可按本领域普通技术人员已知的方法评价。测定CCR1诱导的迁移的公认方法实例可见于Coligan,J.E.,Kruisbeek,A.M.,Margulies,D.H.,Shevach,E.M.,Strober,W.编辑:免疫学中的现行方案(Current Protocols in Immunology)6.12.1-6.12.3(John Wiley and Sons,NY,1991)。下面详述了一个如何测定化合物抑制迁移的活性的具体实例。
趋化性分析:
可应用带一个5μm聚碳酸酯滤器的标准48孔或96孔BoydenChamber评估化合物抑制对各种趋化因子的趋化性的能力。所有试剂和细胞都可在补加了1mg/ml牛血清白蛋白的标准RPMI(BioWhitikker Inc.)组织培养基中制备。简单地说,将MIP-1α(Peprotech,Inc.,P.O.Box275,Rocky Hill NJ)或其他试验激动剂置于Boyden Chamber的下室中。然后装上聚碳酸酯滤器并固定上室。选定的激动剂的量是在此系统中测定产生最大量趋化性的量(例如,就MIP-1α来说,1nM应是足够的)。
然后,就可将通过标准技术分离的THP-1细胞(ATCC TIB-202)、原代人单核细胞或原代淋巴细胞一式三份地与各种浓度的试验化合物一起加到上室中。化合物稀释液可应用标准血清学技术配制并在添加到室中之前与细胞混合。
在37℃下经适当保温培养期(例如,对THP-1细胞为3.5小时,对原代单核细胞为90分钟)后,取出该室,吸出上室中的细胞,擦拭滤器的上部,按下列方法可测定迁移细胞数。
就THP-1细胞来说,可将室(由Neuroprobe制造的96孔型)离心而使细胞离开下室,通过染料二乙酸荧光素(fluorocein diacetate)的颜色变化对照标准曲线可定量细胞数。
就原代人单核细胞或淋巴细胞来说,可用Dif Quik染料(American Scientific Products)将滤器染色,用显微镜测定迁移细胞数。
将所述化合物存在下的迁移细胞数除以对照孔中(不含该化合物)的迁移细胞数。商数(quotant)是该化合物的抑制%,然后,可采用标准制图法将该商数对所用化合物的浓度绘图。再利用曲线拟合分析法根据所有测试浓度确定50%抑制点。对所有数据点的曲线拟合必须具有>90%的相关系数(R的平方)以被认为是有效测定。
