Structure-activity relationships of xanthocillin derivatives as thrombopoietin receptor agonist

Abstract

Xanthocillin derivatives, which show thrombopoietin receptor agonist activity, were synthesized through our developed method. Bioassay data suggest the importance of alkene geometry, the presence of substituents at the benzene ring that support hydrophobic character, and the moderate size of the molecule. One of the two isonitrile group of the natural product appears to be dispensable. © Japan Antibiotics Research Association.
