L-trans-2,4-PDC
Chemical Name: L-trans-Pyrrolidine-2,4-dicarboxylic acid
Purity: ≥97%
Biological Activity
L-trans-2,4-PDC is a potent, competitive, transportable EAAT1-4 inhibitor/non-transportable EAAT5 inhibitor. In [3H]-d-Asp uptake assays in HEK293 cells expressing human EAAT1, EAAT2 and EAAT3, Ki values are 20, 20 and 109 μM, respectively. In a FLIPR Membrane Potential (FMP) assay, Km values for L-trans-2,4-PDC are 7.7, 11 and 19 μM for human EAAT2, EAAT3 and EAAT1, respectively.Technical Data
