2-Phosphoglyceric acid (2PGA) is a glyceric acid which serves as the substrate in the ninth step of glycolysis. It is catalyzed by enolase into phosphoenolpyruvate (PEP) the penultimate step in the conversion of glucose to pyruvate.

ES9-17, an analog of ES9 (endosidin9), is an inhibitor of clathrin-mediated endocytosis (CME). ES9-17 inhibits the uptake of FM4-64 and transferrin. ES9-17 inhibits root growth of Arabidopsis seedings.
