AVLX-125 (UCCB01-125) 是 PSD-95 和 PDZ 结构域的抑制剂，Kd 值为 10 nM，适用于炎症性疼痛的研究。

SCR-4026 is an inhibitor of the nNOS-PSD-95 interaction with neuroprotective activities. SCR-4026 also promotes neural stem cells to differentiate into neurons-like cells.

Palmitic acid-13C is intended for use as an internal standard for the quantification of palmitic acid by GC- or LC-MS. Palmitic acid is a 16-carbon saturated fatty acid. It comprises approximately 25% of human total plasma lipids.1 It increases protein levels of COX-2 in RAW 264.7 cells when used at a concentration of 75 μM.2 Palmitic acid is involved in the acylation of proteins to anchor membrane-bound proteins to the lipid bilayer.2,3,4,5,6 |1.

3,4-Dephostatin is an inhibitor of the interactions of CFTR-associated ligand (CAL) and PSD-95 Dlg1 ZO-1 (PDZ) domain.

Novel cyclic peptide that disrupts interaction between GluR6 and PSD-95

Palmitic acid-13C is intended for use as an internal standard for the quantification of palmitic acid by GC- or LC-MS. Palmitic acid-13C contains 13C at the C2 position and has been used in the study of free fatty acid incorporation into phospholipid fatty acids in soil microbes.1 Palmitic acid is a 16-carbon saturated fatty acid. It comprises approximately 25% of human total plasma lipids.2 It increases protein levels of COX-2 in RAW 264.7 cells when used at a concentration of 75 μM.3 Palmitic acid is involved in the acylation of proteins to anchor membrane-bound proteins to the lipid bilayer.3,4,5,6,7

PDZ1 Domain inhibitor peptide TFA，一种环状肽，以 β-Ala 内酰胺侧链为接头，专一性靶向 PSD-95 的 PDZ1 域。此化合物能干扰 GluR6 PSD-95 间的相互作用，通过与 GluR6 的 C 末端竞争，抑制其在 PDZ1 域的结合。

Tat-NR2BAA TFA 是 Tat-NR2B9c 的对照肽 (control peptide)，没有活性。Tat-NR2BAA TFA 的序列与 Tat-NR2B9c 相似，但在 COOH 末端 tSXV 基序中有一个双点突变，这使得它无法结合 PSD-95。Tat-NR2B9c TFA 是一种可通透细胞膜的多肽，破坏 PSD-95 NMDAR 的结合。

Tat-NR2BAA is an inactive control peptide of Tat-NR2B9c. It shares a similar sequence with Tat-NR2B9c, but possesses a double-point mutation in the COOH terminal tSXV motif. This mutation renders Tat-NR2BAA unable to bind PSD-95. Tat-NR2B9c, on the other hand, is a membrane-permeable peptide that interferes with PSD-95 NMDAR binding. This interference leads to the decoupling of NR2B- and or NR2A-type NMDARs from PSD-95[1][2].

Ethyl-3,4-dephostatin is a novel inhibitor of the interactions of CFTR-associated ligand and PSD-95 Dlg1 ZO-1 domain.
