Based on the fact that petroselinic acid showed good inhibitory activity(IC_(50) = 6.99μmol/L) against protein tyrosine phophatase 1B(PTP1B) in vitro,a series of novel N-(alkoxyphenyl)-aminocarbonylbenzoic acid derivatives were designed and synthesized.The results indicated that most of the derivatives showed more potent activities against PTP1B.Especially,compound 13 had obvious activity with an IC_(50) of 106 nmol/L in vitro.
