Background:

TGX-221 is a potent inhibitor of (phosphatidylinositol 3-kinases) PI3K which specifically inhibits PI3K -p110β isoform with IC50 value of 8.5 nM [1].

In J774.2 macrophage cells, TGX-221 has been demonstrated to reduce insulin-induced phosphorylation of Ser473 of protein kinase B (PKB). While in in CHO-IR and 3T3-L1 cells, TGX-221 has no effect on PKB phosphprylation [1].

In vivo, TGX-221 significantly improved blood flow in FeCl3-induced arterial thrombosis as well as increased tail and renal bleeding times in mice. In addition, TGX-221 has revealed to disrupt CFRs in a Folts model of arterial thrombosis in male Sprague-Dawley rats [2].
