S35225 is a direct inhibitor of Plasminogen Activator Inhibitor type-1 activity in the blood.

The increased risk of thrombotic events associated with disease states such as diabetes and hypertension has been correlated with elevated circulating levels of Plasminogen Activator Inhibitor type-1 (PAI-1). In the present study we evaluate the benzothiophene derivative S35225 in comparison with two recently described inhibitors of PAI-1 activity Tiplaxtinin and WAY140312 on a panel of PAI-1 activity assays in vitro and in vivo. In a direct chromogenic assay, S35225 has an IC50 value of 44+/-0.

Targeting ACE and ECE with dual acting inhibitors.

A series of urea analogues related to SA6817 and a GSK phosphonic acid with reported ACE inhibitory activity were prepared and tested for dual ACE and ECE activities. Although excellent ACE and NEP inhibition was achieved, only modest ECE inhibition was observed with one analogue.
