说明： EAAT2 (GLT-1)-selective non-transportable inhibitor of L-glutamate and L-aspartate uptake
化学名： (2S,3S,4R)-2-Carboxy-4-isopropyl-3-pyrrolidineacetic acid
生物活性 for Dihydrokainic acid
Dihydrokainic acid is a selective EAAT2(GLT1) non-transportable inhibitor of L-glutamate and L-aspartate uptake (Ki = 23 μM). Dihydrokainic acid is 130-fold selective over EAAT1 and EAAT3 (Ki > 3 mM). In [3H]-d-Asp uptake assays in HEK293 cells expressing human EAAT2, EAAT1 and EAAT3, Ki values are 89 μM, > 3 mM and > 3 mM, respectively. Respective Km values in a FLIPR Membrane Potential (FMP) assay, are 31 μM, > 3 mM and > 3 mM

We performed ex-vivo slice physiology on Bed nucleus of the stria terminalis (BNST) slices. We bath applied DHK (300 micromolar) on a BNST neuron in the current-clamp mode. DHK depolarized the neuron and the drug effect washed out.

Huntington's Disease Poster
Huntington's disease (HD) is a severe monogenic neurodegenerative disorder, which is characterized by the prevalent loss of GABAergic medium spiny neurons (MSN) in the striatum. This poster summarizes the effects of mutant huntingtin aggregation implicated in the pathology of HD, as well as highlighting the use of iPSCs for HD modeling.
