ABSTRACT
Objective To use Ex-Rad as a lead compound to design and synthesize aryl benzyl sulfones derivatives with protein tyrosine kinase’(PTK) inhibitory activity. Methods 2-Naphthol was used as a raw material to synthesize intermediates 3a-3f. The target compounds 4a, 4d, and 5a-5f were synthesized by oxidizing 3a-3f in acetic acid with H202. Enzyme-linked immunosorbent assay’ELISA) was used and inhibition rate was calculated to screen out the compounds with PTK inhibitory activitity. Results Eight compounds containing a sulfone or sulfoxide group were synthesized and the structures were confirmed by 1H NMR. Preliminary evaluation of the 8 compounds demonstrated that the PTK inhibitory activity of 5c was much stronger than that of the lead compound. Conclusion The synthetic method is simple, and the materials are cheap and readily available. 5c shows strong PTK inhibitory activity by ELISA.
