Tyrosine kinase inhibitory activity of dehydroabietylamine derivatives tested by homogeneous time-resolved fluorescence based high throughput screening model / 中国天然药物

ABSTRACT

Protein tyrosine kinases (PTKs) are attractive targets in searching for therapeutic agents against many diseases. In this study, a series of dehydroabietylamine derivatives were first determined to show PTK inhibitory activity using a high-throughput screening (HTS) method based on homogeneous time-resolved fluorescence (HTRF) technology. The structure-activity relationships of the dehydroabietylamine derivatives were established, and it was found that the compounds with a nitrogen-containing side chain had better inhibitory activity. Further studies showed that the compounds substituted with halogen in the phenyl ring resulted in higher inhibitory activity on the epidermal growth factor receptor (EGFR), and can be a guide to modify the structure of dehydroabietylamine derivatives. Dehydroabietylamine derivatives might be a new class of multi-targeted and effective PTK inhibitors with structure modifications.
