ABSTRACT
<p><b>OBJECTIVE</b>To synthesize (2'-bromo-4',5'-dimethoxy-phenyl)-( 2,3- dibromo-4,5-dimethoxy-phenyl)-methane (6) as protein tyrosine phosphatase 1B (PTP1B) inhibitor.</p><p><b>METHOD</b>Compound 6 was synthesized by Friedel-Crafts reaction, bromination and decarbonylation and screened inhibitory activity against PTP1B by the colorimetric assay. The structure of synthetic intermediates and target product were identified on the basis of spectral analysis.</p><p><b>RESULT</b>Compound 6 was synthesized successfully in four steps and evaluated for its PTP1B inhibitory activity, the screening result shown that compound 6 displayed good inhibitory activity against PTP1B.</p><p><b>CONCLUSION</b>The target compound 6 was synthesized with the overall yield of 20%, which was a new compound and shown good inhibitory activity against PTP1B (inhibition 40.16% at 5 mg x L(-1)).</p>
