In this study, the CHO_INSR_1284 transgenic cell line was employed as the target cell, utilizing homogeneous time-resolved fluorescence technology to establish a method for detecting the biological activity of insulin degludec. Key parameters were optimized, and validation was conducted in accordance with general principles 9401 and 1431 of the fourth section of the 2020 edition of the Chinese Pharmacopoeia. Results indicated a good dose-response relationship for insulin degludec in this method, aligning with a four-parameter curve. Following optimization, the cell seeding density was set at 3.5×105 cell·mL-1, the initial concentration of insulin degludec at 57.18 μg·mL-1, with a four-fold dilution, a stimulation period of 45 minutes, and an incubation duration of 4 hours. This method demonstrated strong specificity, with the geometric variation coefficient (GCV%) for the five potency levels ranging from 4.1% to 10.6%. The linear regression equation from the linear fitting was y = 1.015x - 0.027 7, and R2 = 0.999 6. The results confirmed the method's good intermediate precision and linearity. The regression term was highly significant (P < 0.01), neither the deviation from parallel terms nor the model mismatch terms were significant (P ≥ 0.05), complying with general rule 1431 of the fourth section of the 2020 edition of the Chinese Pharmacopoeia. This study established a method for detecting the biological activity of insulin degludec using homogeneous time-resolved fluorescence technology, suitable for evaluating the biological activity and quality control of insulin degludec products.

本研究以CHO_INSR_1284转基因细胞系为靶细胞, 利用均相时间分辨荧光技术建立德谷胰岛素生物学活性检测方法。对关键参数进行优化, 并依据中国药典(2020版四部通则9401、1431) 进行验证。结果表明, 德谷胰岛素在本方法中存在良好的剂量效应关系, 符合四参数曲线。经优化, 细胞种板密度为每毫升3.5×105个, 德谷胰岛素初始浓度为57.18 μg·mL-1, 稀释倍数为4倍, 刺激时间为45 min, 孵育时间为4 h。本方法专属性强, 5个效价水平几何变异系数GCV%为4.1%~10.6%, 线性拟合的直线回归方程为y = 1.015x - 0.027 7, R2 = 0.999 6, 结果证明此方法具有的较好中间精密度和线性。且回归项非常显著(P < 0.01), 偏离平行项和模型失拟项均不显著(P ≥ 0.05), 均符合中国药典要求。本研究建立了一种基于均相时间分辨荧光技术的德谷胰岛素生物学活性检测方法, 该方法可用于德谷胰岛素类产品的生物学活性评价和质量控制。

In this study, the CHO_INSR_1284 transgenic cell line was employed as the target cell, utilizing homogeneous time-resolved fluorescence technology to establish a method for detecting the biological activity of insulin degludec. Key parameters were optimized, and validation was conducted in accordance with general principles 9401 and 1431 of the fourth section of the 2020 edition of the Chinese Pharmacopoeia. Results indicated a good dose-response relationship for insulin degludec in this method, aligning with a four-parameter curve. Following optimization, the cell seeding density was set at 3.5×105 cell·mL-1, the initial concentration of insulin degludec at 57.18 μg·mL-1, with a four-fold dilution, a stimulation period of 45 minutes, and an incubation duration of 4 hours. This method demonstrated strong specificity, with the geometric variation coefficient (GCV%) for the five potency levels ranging from 4.1% to 10.6%. The linear regression equation from the linear fitting was y = 1.015x - 0.027 7, and R2 = 0.999 6. The results confirmed the method's good intermediate precision and linearity. The regression term was highly significant (P < 0.01), neither the deviation from parallel terms nor the model mismatch terms were significant (P ≥ 0.05), complying with general rule 1431 of the fourth section of the 2020 edition of the Chinese Pharmacopoeia. This study established a method for detecting the biological activity of insulin degludec using homogeneous time-resolved fluorescence technology, suitable for evaluating the biological activity and quality control of insulin degludec products.

Jing GAO, Lü-yin WANG, Jing LI, Ping LÜ, Xiang-dong GAO, Cheng-gang LIANG. Detection of biological activity of insulin degludec by homogeneous time-resolved fluorescence[J]. Acta Pharmaceutica Sinica, 2024 , 59 (12) : 3347 -3353 . DOI: 10.16438/j.0513-4870.2024-0397
普通胰岛素作用时间短, 需每天规律注射, 容易引起注射部位皮肤硬结、脂肪增生或萎缩, 给患者带来较大痛苦[1, 2]。为了保证药物治疗效果并降低给药频率, 脂肪酸修饰型胰岛素类似物应运而生[3]。德谷胰岛素(insulin degludec, IDeg) 是一种长效胰岛素类似物, 在人胰岛素的基础上去掉B链30位的苏氨酸, 在B链29位赖氨酸上通过L-γ-谷氨酸连接子连接一个十六碳脂肪二酸。辅料中的锌离子有利于IDeg形成稳定的可溶性双六聚体, 苯酚能促进多六聚体沉积在皮下组织中, 形成药物储存库, IDeg单体随着锌离子的扩散缓慢释放入血发挥作用, 这是IDeg长效作用的主要机制; 另外, B链29位的赖氨酸可与血液中的白蛋白结合, 起到次要作用[4, 5]。诺和诺德公司生产的德谷胰岛素注射液诺和达已在全球上市, 我国的同类产品也在注册申请过程中。开发一种生物学活性检测方法, 对于生产工艺开发、产品质量研究、放行检测及潜在的生物类似药可比性研究有重要意义。
胰岛素与受体(insulin receptor, IR) 结合后, IRβ亚基发生磷酸化并激活下游信号通路[6, 7]。均相时间分辨荧光技术(homogeneous time-resolved fluorescence, HTRF) 结合了时间分辨荧光(time-resolved fluorescence, TRF) 和荧光共振能量转移(fluorescence resonance energy transfer, FRET) 两种技术[8]。方法检测原理如图 1所示, 磷酸化的IRβ与抗体混合物形成双抗夹心复合物, 在320 nm的激发光下, 能量供体的荧光基团发射波长620 nm的荧光, 光子可从供体荧光基团转移至受体荧光基团, 被激发的受体荧光基团发射波长665 nm的荧光, 荧光值与磷酸化的IRβ水平呈正相关[9]
HTRF较TRF的优势在于其反应体系小且均匀, 荧光在数小时内恒定, 可进行高通量检测, 实验周期短, 易于操作等[10-12]。HTRF凭借其高效快速、灵敏度高、稳定性好等优点被广泛应用[13-15]
本研究以HTRF为平台, 利用CHO_INSR_1284转基因细胞系, 建立了一种准确、灵敏、稳定、高效的德谷胰岛素生物学活性检测方法。

实验参数的优化   取对数生长期的CHO_INSR_1284细胞, 用完全培养基制成密度分别为每毫升1.5×105、2.5×105、3.5×105、4.5×105个的细胞悬液, 接种于96孔板中, 每孔100 µL, 按照上述检测方法进行检测, 确定最佳种板密度; 设定IDeg初始浓度为28.59、57.18、85.77、114.36 μg·mL-1, 以样品稀释液分别进行4倍系列稀释后测定, 探究IDeg的最佳初始浓度; 将IDeg初始浓度配至57.18 μg·mL-1, 分别进行2、3、4、5、6倍系列稀释后测定, 确定IDeg的最佳稀释倍数; 设置15、25、35、45、55、65 min等6个不同的刺激时间, 以及2、3、4、5、6、7 h等6个不同的孵育时间, 按上述方法进行检测, 确定药物刺激时间和孵育时间。
方法学验证   依据中国药典(2020年版, 四部通则9401) 对本方法的专属性、相对准确度、中间精密度、线性和范围进行考察。依据中国药典(2020年版, 四部通则1431) 对检测结果进行可靠性判断。

可靠性结果检测   中国药典(2020年版, 四部通则1431生物检定统计法) 要求, 用约束模型验证测定结果的可靠性, 要求回归项非常显著(P < 0.01); 偏离平行项和模型失拟项应均不显著(P ≥ 0.05)。个别情况下, 当误差项的方差非常小时, 模型失拟检验结果可能判为显著, 可以误差平均水平替代该次试验水平进行计算。遂对回归项、偏离平行项、模型失拟项、R2进行统计。
细胞代次耐用性研究   同时复苏第5、15、25、36代细胞, 连续传代2次, 进行IDeg生物学活性测定, 验证不同细胞代次的耐用性。
破坏性试验 将IDeg对照品用20 mmol·L-1磷酸盐缓冲液(pH 8.0) 制成8 mg·mL-1的对照品溶液, 于60 ℃水浴锅中加热2、8、16、36、60 h, 以未经处理的对照品溶液为参比, 进行生物学活性测定, 计算相对效价; 取上述处理后的样品进行SEC-HPLC分析, 方法为: 采用SHIMADZU LC-20A高效液相色谱仪, Waters Symmetry Shield TM RP 8色谱柱(4.6 mm × 150 mm, 3.5 μm), 以硫酸钠溶液(pH 5.7)-乙腈(9∶1) 为流动相A, 乙腈-水(5∶5) 为流动相B, 梯度洗脱条件: 0~45 min, 52% A; 45~50 min, 52% A→20% A; 20% A, 1 min; 51~51.1 min, 20% A→52% A; 52% A, 10 min。流速为1.0 mL·min-1, 柱温为40 ℃, 进样量为10 μL, 进样器温度为4 ℃。测定样品的主成分含量。
不同批次德谷胰岛素生物学活性测定   选取3批德谷胰岛素原料药, 用0.01 mol·L-1盐酸溶解后, 按上述方法进行生物学活性检测, 重复3次。
多种胰岛素的体外生物学活性检测   将德谷、赖脯、甘精、门冬、人胰岛素原料药用0.01 mol·L-1盐酸溶解, 按其相对分子质量制成相同初始浓度9.367 nmol·mL-1, 做4倍系列稀释, 共12个稀释度, 按照检测方法进行生物学活性测定。
细胞种板密度分别设定为每毫升1.5×105、2.5×105、3.5×105、4.5×105个, 测定同一份样品的生物学活性, 结果如图 2A所示, 细胞种板密度为每毫升3.5×105个时曲线上各点分布均匀, 信噪比(11.88)、拟合曲线R2 (0.998) 相对较好, 确定种板密度为每毫升3.5×105个。
设定IDeg初始浓度为28.59、57.18、85.77、114.36 μg·mL-1, 测定不同样品的生物学活性, 结果如图 2B所示, 初始浓度为57.18 μg·mL-1时, 曲线上各点分布均匀, EC50值较小(0.873 5), 拟合曲线R2 (0.997) 最好, 选取57.18 μg·mL-1为最佳初始浓度。
设定稀释倍数为2、3、4、5、6倍, 测定不同样品的生物学活性, 结果如图 2C所示, 4倍稀释时曲线上各点分布均匀, 拟合曲线R2 (0.994) 较好, 故选最佳稀释倍数为4倍。
设定刺激时间为15、25、35、45、55、65 min, 测定不同样品生物学活性, 结果如图 2D所示, 刺激时间为45 min时, EC50值(0.563 4) 最小, 确定刺激时间为45 min。
设定孵育时间为2、3、4、5、6、7 h, 测定不同样品的生物学活性, 结果如图 2E所示, 孵育时间为4 h时, 信噪比(11.9)、拟合曲线R2 (0.998) 较好, 确定4 h为最佳孵育时间。
结果如图 3A所示, IGF-1有响应, 但未到达上平台, EGF、辅料空白、样品稀释液均无明显响应, 表明本方法专属性良好。
计算5种效价水平的相对效价, 结果如图 3B所示, 5个效价水平相对效价测定值的平均相对偏倚范围在-4.1%~-0.9%, 表明方法的相对准确度好; 5个效价水平的GCV%均小于11%, 说明该方法的中间精密度较好; 以5个不同效价水平理论值的自然对数(x) 对其相应的效价测定值的自然对数(y) 作直线回归, 采用最小二乘法进行线性拟合, 拟合的直线回归方程为y = 1.015x - 0.027 7, R2 = 0.999 6, 斜率在0.8~1.25之间, R2不低于0.98, 表明该方法在50%~200%的效价水平内线性较好。
本课题对R2、回归项、偏离平行项、模型失拟项进行统计, 以回归与模型失拟评估模型的系统适用性, 偏离平行评估样品适用性, 结果均符合中国药典(2020年版) 规定: R2 ≥ 0.98, 回归项非常显著(P < 0.01); 偏离平行项和模型失拟项均应不显著(P ≥ 0.05)。
不同代次细胞对同一份样品的生物学活性测定结果如图 3C所示: 拟合得到的四参数曲线EC50值、信噪比无明显差异, 说明该细胞株耐用性良好。
图 3F所示, 采用面积归一化法计算, 加热0、2、8、16、36、60 h后主成分含量为99.67%、98.87%、95.82%、90.76%、84.22%、59.33%, 呈下降趋势, 亲水性杂质、疏水性杂质、有关物质含量上升。主成分含量下降导致样品生物学活性发生改变, 将上述破坏性样品进行生物学活性检测, 结果如图 3D所示, 加热2、8、16、36、60 h后的IDeg的生物学活性分别为92.16%、83.54%、68.51%、63.85%、29.99%, 经破坏处理的样品生物学活性与主成分含量呈正比趋势, 表明本方法具有一定的灵敏度。
结果如表 1所示: 分别测定3批IDeg的生物学活性, 每批平行测定3次, 所测结果的RSD (n = 3) 小于10%。
结果如图 3E所示, 胰岛素类似物在本方法中均存在剂量效应关系, 但EC50值存在差异, 从高到低依次为德谷胰岛素(0.133 5)、甘精胰岛素(0.033 6)、人胰岛素(0.013 4)、门冬胰岛素(0.012 2)、赖脯胰岛素(0.009 7)。结果表明, 本方法可用于区分脂肪酸修饰型的胰岛素类似物。
EGF与胰岛素同属于生长因子, 能够调节各种细胞的增殖和分化。二者的特异性受体不同, 但都是跨膜蛋白且具有酪氨酸激酶活性[16]。胰岛素和IGF-1通过胰岛素受体和IGF-1受体(IGF-1R) 介导其生物学效应。IGF-1R与IR是高度同源的酪氨酸激酶受体, 都由两个胞外α亚基和两个跨膜β亚基组成, 通过二硫键连接。在配体与α亚基结合时, IR和IGF-1R构象发生变化, 诱导β亚基的激活。胰岛素和IGF-1优先与自身受体结合, 但也可以低亲和力与替代受体结合。胰岛素和IGF-1在体内的差异效应主要反映了不同组织中激素浓度和受体的相对表达水平, 而不是IR和IGF-1R传递不同信号的能力[17-20]。所以在专属性验证部分, IGF-1有响应但未到达上平台, 其余均无响应。
目前, 对于强制降解研究, ICH Q1B中对高温、高湿、酸/碱水解及氧化等条件均无明确规定。蛋白类药物受温度影响较大, 蛋白构象可能会随着温度的升高而展开或者部分展开, 以至于发生降解或者聚集。持续升高的温度会达到蛋白质融化温度, 导致蛋白质发生不可逆的聚集, 同时还会伴随其他化学反应, 如氧化、脱酰胺等[21]。在本研究中, 将IDeg对照品用20 mmol·L-1磷酸盐缓冲液(pH 8.0) 溶解后, 在60 ℃条件下加热2、8、16、36、60 h与未加热的对照品进行比较, 主成分的含量和生物学活性都随加热时间的增加而降低。提示IDeg有可能发生了降解或聚集, 使得有关物质和高分子蛋白质含量显著增加。
综上所述, 本研究成功建立了一种基于HTRF的可用于检测IDeg生物学活性的新方法, 该方法准确度高, 稳定性好, 高效快速, 可用于研发、过程控制、终产品放行及生物类似药研究, 为IDeg体外生物学活性测定提供一种新的选择。
