EB-3D
Based on 2 publication(s) in Google Scholar
EB-3D is a potent and selective choline kinase α (ChoKα) inhibitor, with an IC50 of 1 μM for ChoKα1. EB-3D exerts effects on ChoKα expression, AMPK activation, apoptosis, endoplasmic reticulum stress and lipid metabolism. EB-3D exhibits a potent antiproliferative activity in a panel of T-leukemia cell lines. Anti-cancer activity.

Biological Activity
IC50: 1 μM; Kd: 0.7 μM[3]
EB-3D displays (0-100 μM; 72 hours) excellent antiproliferative activity against a wide cohort of T-leukemic cell lines, with GI GI50s 13 values in the nanomolar range[1].
EB-3D (1.25-5μM; 24 hours) induced apoptosis in leukemia cell lines[1].
EB-3D (0.5-1 μM; 24 hours) induces a G0/G1 arrest that lead to apoptosis[1].
EB-3D (0.3 μM; 48 hours) shows a first spike of activation of AMPKα after 30 minutes and a later increase in the phosphorylation of T172[1].
EB-3D (1-40 μM; 48 hours) inhibits cell growth in HepG2 cells with a GI50 of 14.55 μM[2].
EB-3D induces deregulation of the AMPK-mTOR pathway and apoptosis in leukemia T-cells[1].

Result:Showed a first spike of activation of AMPKα after 30 minutes of treatment and a later increase in the phosphorylation of T172. The increase in S79 phosphorylation of its main target ACC (acetyl-coenzyme A (CoA) carboxylase), followed the same pattern. This rapid activation of AMPK, in turn induced a consequent reduction in mTOR phosphorylation that is visible already at 30’ and that becomes amplified at longer time probably due to the interruption of feedback loops that are characteristic of mTOR connecting pathways.
