Benzylidene-2,4-thiazolidinedione derivatives with substitutions at both the ortho and para-positions of the phenyl group were synthesized as PTP1B inhibitors with IC50 values in a low micromolar range. Compound 18l, the lowest, bore an IC50 of 1.3 μM. In a peroxisome proliferator-activated receptor-γ (PPAR-γ) promoter reporter gene assay, 18l was found to activate the transcription of the reporter gene with potencies comparable to those of troglitazone, rosiglitazone, and pioglitazone. In vivo efficacy of 18l as an anti-obesity and hypoglycemic agent was evaluated in a mouse model system. Compound 18l significantly suppressed weight gain and significantly improved blood parameters such as TG, total cholesterol and NEFA without overt toxic effects.
Compound 18l was a PTP1B inhibitor with IC50 of 1.3 μM and activated PPAR-γ at 1.0 μM. It suppressed weight gain in a DIO mouse model system.Figure optionsDownload as PowerPoint slide
