Protein tyrosine phosphatase 1B (PTP1B) inhibitor has recently been identified as new candidate drug for type Ⅱ diabetes and obesity due to it is a negative regulator of the insulin and leptin-signaling pathway. In order to find new nonphosphonate-based pTyr mimetics, a series of novel chalcone derivatives bearing 1H-benzo[d]imidazol or 1H-benzo[d] [1,2,3]-triazol moieties were designed, synthesized, and evaluated for their PTP1B inhibitory activities. The results demonstrated that all compounds presented potent inhibitory activities against PTP1B, among which 2-(1H-benzo[d] [1,2,3]triazol-1-yl)-N'-(4-(3-(naphthalen-2-yl)-3-oxoprop-1-en-1-yl)benzylidene)acetohydrazide (10i) exhibited the best potency with IC50 value of (2.98±0.04) μmol·L-1. Importantly, 2-(1H-benzo[d] [1,2,3]triazol-1-yl)-N'-(4-(3-oxo-3-(p-tolyl)prop-1-en-1-yl)benzylidene)-acetohydrazide (10h) showed no significant inhibition on T-cell protein tyrosine phosphatase (TCPTP) at the concentration of 20 μg/mL, suggesting the highly selectivity of this agent toward PTP1B.
