| 英文摘要 | We report a capillary electrophoresis method in conjunction with liquid chromatography-tandem mass spectrometry (LC-MS/MS) for screening of protein kinase inhibitors (PKIs) in natural extracts. Protein kinase A (PKA), substrate 5-carboxyfluorescein-labeled kemptide (CLK) and inhibitor H-89 were employed for the method development and validation. Enzymatic inhibition assay was performed with electrophoretically mediated microanalysis technique. Once the bioactivity of a natural extract was confirmed, an assay-guided isolation and structure elucidation using LC-MS/MS were accomplished to identify the compounds which are responsible for the observed bioactivity. Totally 33 natural extracts were screened with the method, and baicalin in the extract of Radix Scutellariae was identified to be a new PKI of PICA. This result demonstrated the practical applicability of our method in screening of PKIs from natural products. (C) 2014 Elsevier B.V. All rights reserved. |
