EA4 Chemical Properties,Uses,Production
Uses
EA4, a derivative of quinone, is an inhibitor for both rPLA and cPLA. EA4 can inhibit rPLA2 with a Ki value of 130 μM. EA4 can be used for the research of hemostasis, thrombosis, and erythropoiesis[1].
Biological Activity
ki: 130 μmea4 is a rpla2 inhibitor.rpla2, a calcium-dependent cytosolic phospholipase a2 (cpla2), was initially isolated and characterized from bovine and human red blood cells. with a molecular mass of 42 kda, cpla2 shows biochemical properties similar to cpla2 type iv.
in vitro
it was found that ea4 was able to inhibit a ca(2+) ionophore-induced arachidonic acid release from both human and bovine red blood cells, demonstrating that this enzyme was responsible for the ca(2+)-dependent arachidonic acid release from mammalian red blood cells [1]. another study found that in mouse hepatoma hepa-1c1c7 cells, ea4 could cause a significant induction of the cyp1a1-mediated ethoxyresorufin o-deethylase activity time- and concentration-dependently, and such induction was accompanied by an increase of the cyp1a1 mrna transcription. morevoer, in human cells including mcf-7 (human breast adenocarcinoma cell line), hepg2 (human hepatocarcinoma), and hl-60 (human promyelocytic cell line), the expression of cyp1a1 mrna could be also induced by ea4 treatment. in addition, cyp1b1 mrna was increased by ea4 in mcf-7 cells [2].
