Tat-NR2B9c(TFA)是由20个氨基酸组成的多肽，为PSD-95的抑制剂，对PSD-95d2和PSD-95d1的EC50值分别为6.7nM和670nM。Tat-NR2B9c同时可降低NMDA诱导的p38的活化，具有神经保护作用。
Tat-NR2B9c (TFA) is a 20-aa peptide, which acts as a postsynaptic density-95 (PSD-95) inhibitor, with an EC50 of 6.7 nM for PSD-95d2 (PSD-95 PDZ domain 2), and 670 nM for PSD-95d1[1]. Tat-NR2B9c also reduces NMDA-induced p38 activation, and possesses neuroprotective efficacy[2]. EC50: 6.7 nM (PSD-95d2), 670 nM (PSD-95d1)[1]p38[2]
