Abstract :

Signal Transducer and Activator of Transcription 3 (STAT3) is a component of the JAK/STAT pathway. Therapeutic inhibition of STAT3 has been of high interest, as its aberrant activation has been linked to cancer, inflammation and other human diseases. The withanolide family natural product Withaferin A inhibits STAT3 activation. We designed, synthesized and evaluated simplified withanolide analogues SLW1 and SLW2 and found that SLW1 retained the STAT3 inhibitory activity of Withaferin A.
