Based on a non-competitive and selective PTP1 B inhibitor reported by us previously, thirtynine benzamido derivatives were designed and synthesized as novel PTP1 B inhibitors. Among them,twelve compounds exhibited IC_(50) values at micromolar level against human recombinant PTP1 B, and most of them exhibited significant selectivity to PTP1 B over TC-PTP and CD45. Further evaluation of the most potent compound 27 on high-fat diet(HFD)-induced insulin-resistant(IR) obese mice indicated that27 could modulate glucose metabolism and ameliorate dyslipidemia simultaneously.& 2018 Chinese Pharmaceutical Association and Institute of Materia Medica, Chinese Academy of Medical Sciences.
