Synthesis, biological evaluation and 3D-QSAR studies of imidazolidine-2,4-dione derivatives as novel protein tyrosine phosphatase 1B inhibitors

Protein tyrosine phosphatase 1B (PTP1B) plays a vital role in the regulation of insulin sensitivity and dephosphorylation of the insulin receptor, so PTP1B inhibitors may be potential agents to treat type 2 diabetes. In this work, a series of novel imidazolidine-2,4-dione derivatives were designed, synthesized and assayed for their PTP1B inhibitory activities. These compounds exhibited potent activities with IC50 values at 0.57-172 μM. A 3D-QSAR study using CoMFA and CoMSIA techniques was carried out to explore structure activity relationship of these molecules. The CoMSIA model was more predictive with q2 Combining double low line 0.777, r2 Combining double low line 0.999, SEE Combining double low line 0.013 and r2pred Combining double low line 0.836, while the CoMFA model gave q2 Combining double low line 0.543, r2 Combining double low line 0.998, SEE Combining double low line 0.029 and r2pred Combining double low line 0.754. The contour maps derived from the best CoMFA and CoMSIA models combined with docking analysis provided good insights into the structural features relevant to the bioactivity, and could be used in the molecular design of novel imidazolidine-2,4-dione derivatives.

Synthesis of novel imidazolidine-2,4-dione derivatives as potential antidiabetic agents

A series of novel imidazolidine-2,4-dione derivatives were synthesized and their chemical structures were confirmed by 1H NMR and ESI-MS. The preliminary antidiabetic screening results demonstrated that the compound 3b showed some antidiabetic activity and could acted as lead compound for further design and discovery of antidiabetic agents.
