新的取代五元氮杂环盐类化合物及其
治疗蛋白老化相关疾病的用徐一 技术领域
本发明涉及取代五元氮杂环盐类化合物, 其制备方法, 含有它们 的药物组合物以及所述化合物在预 或治疗与 AGE ( advanced glycosylation endproducts AGE ) 有关的疾病或症状中的用途, 如 ( i)增加皮肤弹性或者减少皮肤皱纹, ( ii) 治疗糖尿病, ( iii) 治疗或緩解糖尿病的后遗症, ( iv) 治疗或緩解肾脏损伤, (V) 治疗 或緩解血管损伤, (vi) 治疗或緩解高血压, (vii) 治疗或緩解视网 膜病变, (viii) 治疗或緩解晶状体蛋白损伤, ( ix) 治疗或緩解白 内障, (X) 治疗或緩解周围神经病, (xi) 治疗或緩解骨关节炎。 背景技术
已知糖和蛋白之间存在反应, 早在 1912年, Maillard发现葡萄 糖和其它还原糖与氨基酸反应, 经过一系列的脱氢重排形成了稳定的 褐色色素, 进一步的研究发现贮存和加热食物也能够产生这种由糖和 多肽形成的色素,这种色素的形成降低了蛋白的生物活性, 相关的应 用专利可以参考 US.08/588249。 这种非酶催化的还原糖和自由氨基 酸的反应会形成一种稳定二酮基副产物, 即已知的 Amadori产物。 特 别是血红素表面氨基酸的 β侧链残基与葡萄糖反应生成血红素 Alc。 体内其它蛋白也会发生这样的反应, 比如晶状体、 胶原蛋白和神经蛋 白 ( Advanced Glycosylation; Chemistry, Bi lolgy and
Implications for Diabetes and Aging, Advances in Pharmacology, Vol.23, p.1-34A cademic Press 1992 ) 。
上述反应在糖尿病血糖水平增高的情况下会加速发生, 正常血糖 状态下也会发生上述反应。 同时衰老过程与脂褐素的形成密切相关, 同样胶原蛋白老化在体外可以用糖和胶原蛋白模拟。 葡萄糖诱导的胶 原产物被其它蛋白捕获反应, 这样引起了蛋白之间的交联反应。 这种 葡萄糖诱导的交联反应所产生的是晚期糖基化终产物 ( advanced glycosylation endproducts AGEs ) , 已知 AGE 与糖尿病的并发症 相关, 正常的衰老过程也引起 AGEs的增加, 体内的 AGEs不仅由于其 异常的病理化学结构而且还会被一些特定的受体识别从而引起复杂的 糖尿病和衰老相关的病理改变。
目前, 已经有一些通过阻止 AGE 的累积方面的治疗方法。 其中一 个方法可参见 U. S.4758583,其先导物氨基胍及其类似物可以阻止 AGE 的形成,通过与早期糖基化产物反应从而阻止了糖基化产物进一步转 化成为 AGEs, 同时也阻止了 AGE 与组织进一步交联。 这个方法的有 效性在糖尿病和老龄化大鼠的动物模型上进行了评价, 同时也包括如 大血管、 肾脏和神经病理方面的其他指标。 Vlassara 等人对这些数 据 行了总结。 ( Vlassara et al, 1994 Biology of Diseases,
" Pathogenic effects of advanced glycosylation: biochemical, biologic and clinical implications for diabetes and aging ,, Laboratory Investigation 70: 138-151;
Brownlee, 1995, " The pathological implica tions of protein glycation" Clin. Invest. Med., 18: 275-281;以及 Brownlee, 1995:
"Advanced protein glycosylation in diabetes and aging" , Ann. Rev. Med.46: 223-34. )
另一种控制组织中 AGEs 的方法特别是在組织中已经形成并累积 的 AGEs 交联产物 (这些交联产物导致临床或者亚临床病理改变) 的 方法是逆转或者裂解已经形成的 AGEs 交联产物。 Vassan等人证明这 种裂解 AGEs 的方法是有效的 ( vassan et al Nature.1996, Vol. 382 (18) 275-278 ) 。 在美国专利 US.5656261 以及 US08/588249 和 US08/848776 中公布的化合物、 制剂以及方法都可以在体内和体外裂 解已经形成的 AGE交联结构。 研究表明这类化合物对于衰老造成的心 血管疾病有良好的作用 ( Wolffenbuttel et al., 1998, "Breakers of Advanced Glycation End Products Restores Large Artery Properites in Experimental Diabetes ,, , Pro Nat. Acad. Sci.U. S. A.95: 4630-4634 ) 。 在这些研究中, 给予 9 周的糖尿 病大鼠 AGEs 裂解剂 1-3周逆转了由于糖尿病造成的大动脉硬化。 改 善的参数有心输出量、 外周阻力、 体动脉顺应性、 主动脉输入阻力以 及颈动脉顺应性 ( U. S. 6319934 ) 。
发明内容
本发明的目的是寻找并且开发作用于 AGE的小分子裂解剂, 用来 裂解已经形成的 AGE 从而阻止蛋白交联, 对已经交联的蛋白进行裂 解, 从而促进蛋白的代谢, 进一步改善由于 AGE在体内的增高从而导 致的各种病理改变, 包括增加皮肤弹性或者減少皮肤皱紋, 治疗糖尿 病或者治疗或緩解糖尿病的后遗症、 腎脏损伤、 血管损伤、 高血压、 视网膜病变、 晶状体蛋白损伤、 白内障、 周围神经病或者骨关节炎。 同时这种蛋白交联结构裂解剂所作用的糖基化蛋白不局限于人体蛋 白, 还包括农作物中的植物蛋白或者动物蛋白, 因而可以扩展用于农 作物中植物蛋白和动物蛋白的保鲜用途。

发生在口腔中的非酶促反应可以导致牙齿着色。 目前所使用的抗 蛀蚀剂可以加速这种碳基化反应进一步导致了牙齿的着色。 最近有一 类具有抗蛀蚀功能的阳离子杀菌剂用于常规口腔清洗。 这些阳离子抗 菌剂有阿莱西丁, 十六烷基吡啶氯酸盐等等。 而这些制剂可以加速糖 基化反应中关键的一步 Mai l lard 反应, 进而加速牙齿的着色 ( Nordbo, J. Dent. Res. , 58: 1429 (1979) ) 。 并且有报道在体外观察 到了洗必泰和洁而灭能够催化糖基化反应 (褐化反应) 。 由于 Mai l lard 反应, 洗必泰加入糖和氨基酸的混合物中加速了色素的形 成。 基于上述原因, 本发明所涉及的化合物及其药物组合物可以用于 口腔。 特别是用作口腔清洗液和牙膏中的添加剂。
在有关本发明化合物的上述用途中, 可以采用无毒且药学上可接 受的载体的适当形式应用于洁口液和牙膏中。

当口服用药时,本发明化合物可制成任意口服可接受的制剂形式, 包括但不限于片剂、 胶嚢、 水溶液或水悬浮液。 其中,片剂使用的载 体一般包括乳糖和玉米淀粉,另外也可加入润滑剂如硬脂酸镁。 胶嚢 制剂使用的稀释剂一般包括乳糖和干燥玉米淀粉。 水悬浮液制剂则通 常是将活性成分与适宜的乳化剂和悬浮剂混合使用。 如果需要,以上 口服制剂形式中还可加入一些甜味剂、 芳香剂或着色剂。

另外需要指出,本发明化合物的使用剂量和使用方法取决于诸多 因素,包括患者的年龄、 体重、 性别、 自然健康状况、 营养状况、 化 合物的活性强度、 服用时间、 代谢速率、 病症的严重程度以及诊治医 师的主观判断。 优选的使用剂量介于 0.01~100mg/kg体重 /天, 其中 最优剂量在 20mg/kg- 30mg/kg体重 /天。
