4H-PYRIDO[1,2-A]PYRIMIDIN-4-ONE, 7-METHYL-2-(4-MORPHOLINYL)-9-[1-(PHENYLAMINO)ETHYL]- Chemical Properties,Uses,Production

Uses

TGX-221 is a potent, selective, and cell permeable inhibitor of Phosphatidylinositol 3-kinase (PI3K) p110β.

Definition

ChEBI: 9-(1-anilinoethyl)-7-methyl-2-(4-morpholinyl)-4-pyrido[1,2-a]pyrimidinone is a pyridopyrimidine.

General Description

A cell-permeable morpholino-pyrimidinone compound that acts as a reversible, ATP-competitive, selective, and highly potent inhibitor of PI 3-Kβ (IC₅₀ = 0.005, 0.1, 5, and ≥3.5 μM for -β, -δ, -α and -γ isoforms, respectively) with little activity against a panel of 15 commonly studied protein kinases even at concentrations as high as 10.0 μM. An excellent tool for studying p110β-dependent responses both in cells in vitro and in animals in vivo.

Biological Activity

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].

Biochem/physiol Actions

Cell permeable: yes

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].

storage
