A substructure similarity search against the SPECS database and chemical synthesis methods were performed to obtain a series of pyrazolidine-3,5-dione derivatives. Through the enzyme-based assay against c-Met kinase, 4 compounds (1c, 1e, 1m and 1o) showed potential inhibitory activity, with IC50 values mostly less than 10 μM. Based on the structure–activity relationship (SAR) and binding mode analysis
The present invention is related to the use of alkylidene pyrazolidinedione derivatives of formula (I) for the treatment and/or prevention of diabetes type I and/or II, impaired glucose tolerance, insulin resistance, hyperglycemia, obesity and polycystic ovary syndrome (PCOS). In particular, the present invention is related to the use of alkylidene pyrazolidinedione derivatives of formula (I) to modulate, notably to inhibit the activity of PTPs, in particular PTP1B, TC-PTP, SHP and GLEPP-1. The present invention is furthermore related to novel alkylidene pyrazolidinedione derivatives. (I) R1 and R2 represent independently from each other an unsubstituted or substituted aryl or heteroaryl.
