ABSTRACT:
The present invention provides new tyrphostin derivatives acting as substrate competitive protein tyrosine kinase (PTK) inhibitors and receptor tyrosine kinase (RTK) inhibitors, methods of their preparation, pharmaceutical compositions including such compounds, and methods of using these compounds and compositions, especially as chemotherapeutic agents for preventions and treatments of PTK and RTK related disorders such as metabolic, fibrotic, and cell proliferative disorders, in particular psoriasis and cancer.
