SCH66336, inhibitor of protein farnesylation, blocks signal transducer and activators of transcription 3 signaling in lung cancer and interacts with a small molecule inhibitor of epidermal growth factor receptor/human epidermal growth factor receptor 2.

Abstract excerpt

Signal transducer and activators of transcription 3 (STAT3) is an important transcription factor that is essential for lung cancer cell survival. STAT3 is activated by diverse upstream receptor and nonreceptor tyrosine kinases, and blockade of STAT3 results in tumor growth inhibition. Therefore, a search for STAT3 inhibitors is under way. We demonstrate that SCH66336, at 4 mumol/l, completely blocks STAT3...
