PROCESSES FOR DETERMINING THE BIOLOGICAL ACTIVITY OF EPIDERMAL GROWTH FACTOR RECEPTOR TYROSINE KINASE INHIBITORS

摘要

The present invention relates to processes for determining the biological activity of compounds that inhibit the tyrosine kinase activity of the Epidermal Growth Factor Receptor (EGFR) aqnd to the use of transcription or translation products of genes the expression levels of which correlate with the biological activity of an EGFR tyrosine kinase inhibitor for determining the biological activity of such an EGFR tyrosine kinase inhibitor.
