Objective: To establish a method for related substances determination in timolol maleate by ultra-high performance liquid chromatography-quadrupole/orbitrap high resolution mass spectrometry(UPLC-Q/Orbitrap HRMS),by which the impurities both in active pharmaceutical ingredients(APIs) and preparations can be recognized and determined.
Methods: An ACE Excel3 C18-AR column(150 mm×4.6 mm,3 μm)was used for the separation and a mixture of 0.01 mol·L-1 ammonium acetate solution with 0.02% formic acid and methanol was employed as the mobile phase by gradient elution,at a flow rate of 0.6 mL·min-1. The detection wavelength for UV detector was 295 nm,an HESI(heated ESI)ion source was employed in both the positive mode and negative mode. The possible fragmentation patterns prediction was conducted with the help of Mass Frontier 8.0 and Compound Discover 3.3. The related substances could be recognized and determined by means of the forced degradation of the APIs,with the calibration by the correction factors and confirmation by the mass spectrum data from UPLC-Q/Orbitrap HRMS.
Results: The timolol impurity B[3-(tert-butylamino)-2-(4-morpholino-1,2,5-thiadiazol-3-yloxy)propan-1-ol],timolol impurity D(4-morpholino-1,2,5-thiadiazol-2-ol),timolol impurity E((S,Z)-4-({1-(tert-butylamino)- 3-[(4-morpholino-1,2,5-thiadiazol-3-yl) oxy] propan-2-yl}oxy)-4-oxobut-2-enoic acid maleate salt) and timolol impurity C[N-(tert-butyl)-2,3-bis (4-morphloline-1,2,5-thiadiazol-3-yloxy) propan-1-amine maleate] were produced from the APIs under selected conditions and separated well in the specified HPLC condition,the limit of quantitation was 0.05 μg·mL-1 and the limit of detection was 0.015 μg·mL-1 for HPLC-UV. The contents of individual impurities were between 0.000 4%-0.09% and the results of total impurities were between 0.02%-0.12% for the samples from 4 different manufactures. The probable chemical structures of the 6 unspecified impurities were speculated according to the fragmentation pattern of fragment ions,combined with the fragment information,chemical structure of API and the references.
Conclusion: The system solution can be obtained by the degradation of the API,and be implied in the impurity analysis for the timolol maleate. The results can be used as a reference for the quality control of timolol maletae.

目的: 采用超高效液相色谱-四极杆/静电场轨道阱质谱(UPLC-Q/Orbitrap HRMS)鉴定马来酸噻吗洛尔中的有关物质。
方法: 采用ACE Excel3 C18-AR(150 mm×4.6 mm,3 μm)色谱柱,以含0.01 mol·L-1乙酸铵的0.2%甲酸水-甲醇为流动相梯度洗脱,流速0.6 mL·min-1,紫外检测器检测波长295 nm,质谱检测器采用HESI离子源,正负离子检测模式,碎片和裂解分析借助Mass Frontier 8.0和Compound Discover 3.3软件,通过对主成分进行破坏可以获得系统适用性溶液对样品中的杂质采用UPLC-Q/Orbitrap进行鉴定和分析。
结果: 主成分在特定条件下可产生出噻吗洛尔杂质B{(±)-1-(叔丁氨基)-2-[(4-吗啉基-1,2,5-噻二唑-3-基)氧]-1-丙醇}、噻吗洛尔杂质D(4-吗啉基-1,2,5-噻二唑)、噻吗洛尔杂质E((S,Z)-4{(-)-1-(叔丁氨基)-2[(4-吗啉基-1,2,5-噻二唑-3-基)氧]-4-氧代丁烯二酸})和噻吗洛尔杂质C{(±)-N-(叔丁氨基)-2,3-二[(4-吗啉基-1,2,5-噻二唑-3-基)氧]-2-丙烷胺},噻吗洛尔峰和各杂质峰分离良好,采用紫外检测器测定,定量限为0.05 μg·mL-1,检测限为0.015 μg·mL-1。结合UPLC-Q/Orbitrap HRMS结果和文献报道,推测了另外6个主要杂质的结构。4家企业生产的8批样品测定结果单个杂质含量在0.000 4%~0.09%,总杂质含量在0.02%~0.12%。
结论: 通过主成分破坏可获得系统适用性溶液,并用于马来酸噻吗洛尔中杂质的检测与鉴定,结果可为马来酸噻吗洛尔的质量控制提供参考依据。
