The use of inductively coupled plasma mass spectrometry as a detector in drug metabolism studies

Background: The inherent properties of element selectivity combined with high sensitivity and structure independent response, make inductively coupled plasma mass spectrometry (ICP-MS) an interesting alternative detection technique in drug metabolism studies. Objective: The application of online separation with ICP-MS detection in drug metabolism studies is reviewed with focus on the merits and demerits of this detection technique. The prerequisite for inclusion in this review is that the study involves a separation technique hyphenated online to the ICP-MS detection. Result/conclusion: ICP-MS detection is found to be advantageous for analysis of all drug substances detectable by ICP-MS compared to radiochemical detection. Detectable drugs are limited to halogen-, sulfur-, metal- and metalloid-containing compounds. The drawback of interference from endogenous compounds on quantitative mass balance estimations of non-metal drugs is addressed. The potential of determining the stoichiometry in metallo-drug biomolecule interactions is pointed out by presenting examples of simultaneous monitoring of metals in metallo-drugs and intrinsic ICP-MS detectable elements in biomolecules. It is concluded that ICP-MS detection is an indispensable technique in drug metabolism studies of metallo-drugs, although the applicability for traditional drugs is limited.

An approach to develop binary chromatographic fingerprints of the total alkaloids from Caulophyllum robustum by high performance liquid chromatography/diode array detector and gas chromatography/mass spectrometry

An approach was proposed to develop binary chromatographic fingerprints by means of high performance liquid chromatography/diode array detector (HPLC/DAD) and gas chromatography/mass spectrometry (GC/MS). HPLC fingerprint and GC/MS fingerprint that, respectively, represent chemical characteristics of aporphinoid and quinolizidine alkaloids of the total alkaloids from Caulophyllum robustum were developed, which were used to construct binary chromatographic fingerprints of the total alkaloids. Moreover, the authentication and validation of the binary fingerprints were performed. Then, a data-level information fusion method was employed to capture the chemical information encoded in two chromatographic fingerprints. Finally, based on the fusion results, the quality of 10 batches of the total alkaloids samples was further evaluated by similarity measure and cluster analysis method. In comparison with conventional fingerprint, the binary chromatographic fingerprints which represent the characteristics of more constitutions can comprehensively and properly reveal the quality characteristics of the total alkaloids. The binary chromatographic fingerprints can reach more objective conclusions in the practice of quality control of the total alkaloids. In conclusion, the binary chromatographic fingerprints are suitable for quality control of the total alkaloids. The presented approach is a powerful and meaningful tool to comprehensively conduct the quality control of traditional Chinese medicine (TCM).     

The application of inductively coupled plasma mass spectrometry in pharmaceutical and biomedical analysis

With the development of life science, pharmaceutical and biomedical analysis becomes more and more important in medical science. Further studies will be hopefully established if it is possible to use inorganic elemental standards or small organic compounds in the quantitative determination of all kinds of drugs, nucleotides and sulfur or phosphorus containing peptides and proteins at appropriate concentration with an acceptable accuracy. Since 1980, inductively coupled plasma mass spectrometry (ICP-MS) has emerged as a new and powerful analytical technique which is suitable for element and isotope analysis. It offers extremely wide detection range of element and co-analysis of most elements in the periodic table. Also, it can be applied to perform qualitative, semiquantitative, and quantitative analysis and isotopic ratios through mass-to-electric charge ratio. With the help of ICP-MS, the struggle of searching for an excellent quantification technique in, e.g. drugs and proteomics has come appreciably close to an end. This review mainly focuses on the introduction of application of ICP-MS in pharmaceutical and biomedical analysis. Some problems in application and the handling strategies are simply presented at the end.

Techniques: the application of accelerator mass spectrometry to pharmacology and toxicology

The exquisite sensitivity of accelerator mass spectrometry (AMS) is being used in biomedical applications to quantitate many isotopes, including 14C, 3H, 41Ca and 27Al, at attomole (10(-18)) concentrations. This enables compounds and metabolites to be measured in human urine and plasma after administration of low pharmacologically or toxicologically relevant doses of labelled chemicals and drugs. The detection of modified proteins or DNA in target organs after dosing with potential carcinogens has also been achieved in many studies. Advances aimed at increasing sample throughput and expanding applications by coupling AMS instruments directly to chromatographic separation systems are currently underway.
