Mechanism of Action

Targets/IC₅₀/Ki	p110β ^[5] (Cell-free assay) 5 nM p110δ ^[5] (Cell-free assay) 0.1 μM
In vitro	The activity of TGX-221 against different isoforms is measured in an in vitro PI3K assay using multiple preparations of recombinant p85/p110. This compound shows slow potent to p110δ with IC50 of 211 nM. Furthermore, it partially attenuates insulin-induced phosphorylation of Ser⁴⁷³ of PKB in J774.2 macrophage cells. ^[1] This chemical inhibits platelet-ECC interaction, platelet aggregation and platelet-granulocyte binding in an extracorporeal circulation (ECC) model. ^[2] A recent study shows that after treatment with this compound (0.2, 2, and 20 μM), PC3 cells show inhibition of proliferation with a significant reduction of the activity of the p110β PI3K isoform. ^[3]
Kinase Assay	Lipid kinase activity
Kinase Assay	IC50 values are measured using a standard lipid kinase activity with PI as a substrate. (i)100 μM cold ATP is used instead of 10 μM, (ii) the DMSO concentration is 1%, and (iii) [γ-³³P]ATP is used instead of [γ-³²P]ATP. The TLC plates are quantified using a phosphorimager screen. The reported IC50 values are determined by non-linear regression analysis on the basis of at least three independent experiments repeated across multiple preparations of recombinant protein.
In vivo	As an anti-thrombotic agent, TGX-221 at doses 1 + 1 (49 %) and 3+3 (88 %) improves integrated blood flow over 30 minutes in a mouse model. In addition, Tail bleeding time (BT) (sec) increases with this compound at doses of 3 + 3 (median 1560) and 1 + 1 (1305) and mean renal BT (sec) also increases in all TGX-221 groups. ^[4]
