Description

一种测定药盒中2β-[N,N'-双(2-巯乙基)乙撑二胺]甲基-3β-(4-氯苯基)托烷含量的方法
技术领域
一种测定药盒中2β-[N,N’-双(2-巯乙基)乙撑二胺]甲基-3β-(4-氯苯基)托烷含量的方法,涉及TRODAT-1的含量测定技术领域。
背景技术
锝[99mTc]-2β-[N,N’-双(2-巯乙基)乙撑二胺]甲基-3β-(4-氯苯基)托烷(99mTc-TRODAT-1)是第一个锝[99mTc]标记的成功用于人体的多巴胺转运蛋白显像剂,它能与脑内的多巴胺转运蛋白特异结合而浓聚于纹状体,提供清晰的图像,提示多巴胺能系统的变化信息。国内外大量的人体研究显示:以99mTc-TRODAT-1为显像剂进行单光子发射计算机断层(SPECT)显像,对有关的疾病特别是对帕金森病的早期诊断具有极佳的临床应用潜力,该显像剂即将在国内外上市。
临床上使用的99mTc-TRODAT-1是由TRODAT-1药盒在使用前制备的,因此TRODAT-1药盒的质量关系到99mTc-TRODAT-1的质量能否应用于人体。在对TRODAT-1药盒进行质量控制时,药盒中TRODAT-1的含量是一个关键的指标,目前国内外均没有测定药盒中TRODAT-1的含量的报道。
发明内容
本发明的目的是提供一种测定药盒中TRODAT-1含量的方法,便于进行TRODAT-1药盒的质量控制。
本发明的技术方案:(1)确定标准曲线方程:精密吸取浓度为1mg/ml的TRODAT-1标准溶液从40~150μL范围内均衡选取5~6个点值,各置于分液漏斗中,依次加入三氯甲烷,溴麝香草酚兰溶液,pH缓冲液,振摇后,静置使分层,分取澄清的三氯甲烷层,用无水硫酸钠干燥后置比色皿中,以不加TRODAT-1标准溶液,按上述相同步骤制成的三氯甲烷溶液为空白,于紫外分光光度计上分别测定吸光度值,根据吸光度值与加入的TRODAT-1量计算出标准曲线方程;(2)测定药盒中TRODAT-1的含量:再将TRODAT-1药盒用pH缓冲液溶解,加入分液漏斗中,加入三氯甲烷,溴麝香草酚兰溶液,振摇后,静置使分层,分取澄清的三氯甲烷层,用无水硫酸钠干燥后置比色皿中,测定吸光度值,将吸光度值代入标准曲线方程,计算出药盒中TRODAT-1的含量。
所用pH缓冲液是磷酸盐、柠檬酸盐、铵盐、醋酸盐、酒石酸盐、碳酸盐、硼酸盐、巴比妥盐、邻苯二钾酸盐中的一种或一种以上的混合物溶液,其pH值范围为3.0-5.0。
吸光度值的测定波长为410-420nm,各种试剂的用量为:pH缓冲液5ml,三氯甲烷8ml,溴麝香草酚兰溶液4ml。
制备标准溶液所用的pH缓冲液的pH值为4.0,溶解TRODAT-1药盒所用的pH缓冲液的pH值为3.58,吸光度值的测定波长为414nm。
本发明的有益效果:本发明提供了一种测定药盒中TRODAT-1含量的方法,操作简单易行,重复性好,可以用来对药盒中TRODAT-1的含量进行控制。
