Ezatiostat

生物活性

Ezatiostat hydrochloride (TER199; TLK199 hydrochloride) is a tripeptide analog of glutathione and is a selective and orally active glutathione S-transferase P1-1 (GSTP1) inhibitor. Ezatiostat hydrochloride leads to JNK activation by inhibiting GSTP1. Ezatiostat hydrochloride stimulates both lymphocyte production and bone marrow progenitor proliferation. Ezatiostat hydrochloride has the potential for myelodysplastic syndrome (MDS) treatment[1][2].

IC50 & Target

Glutathione S-transferase P1-1 (GSTP1)[1]
体外研究
(In Vitro)

Ezatiostat causes dissociation of the enzyme from the jun-N-terminal kinase/c-Jun (JNK/JUN) complex, leading to JNK activation by phosphorylation. The therapeutic action of ezatiostat appears to include both proliferation of normal myeloid progenitors as well as apoptosis of the malignant clone[1].
Selection of a resistant clone of an HL60 tumor cell line through chronic exposure to Ezatiostat (TLK199) results in cells with elevated activities of c-Jun NH2 terminal kinase (JNK1) and ERK1/ERK2, and allowes the cells to proliferate under stress conditions that induced high levels of apoptosis in the wild type cells[2].

体内研究
(In Vivo)

Administration of Ezatiostat (TLK199), stimulates both lymphocyte production and bone marrow progenitor (colony-forming unit-granulocyte macrophage) proliferation, but only in glutathione S-transferase P1-1 (GSTP1+/+) and not in GSTP1-/- animals[2].

生物活性

TLK117, the active metabolite of TLK199, selective inhibits Glutathione S-transferase P1–1 (GSTP1-1) with a Ki of 0.4 μM for GSTP. TLK117 also competitively inhibits glyoxalase I with a Ki of 0.56 μM.

IC50 & Target

Ki: 0.4 μM[1], 0.56 μM (glyoxalase I)[2]
体外研究
(In Vitro)

TLK117 is the most specific GSTP inhibitor to date, with a binding affinity greater than GSH itself and a selectivity for GSTP over 50-fold greater than the GSTM and GSTA classes (Ki=0.4 μM)[1]. TER 117 is developed as a GST P1-1 isoenzyme inhibitor to circumvent the indicated contribution of GST P1-1 to drug resistance of tumor cells. To facilitate the cellular uptake of TER 117, it is delivered as a diethyl ester (TER 117 DEE, also called TER 199). TER 117 is found to be a competitive inhibitor of both GST P1-1 and glyoxalase I[2].

体内研究
(In Vivo)

Oropharyngeal administration of the GSTP inhibitor, TLK117, at a time when fibrosis is already apparent, attenuated bleomycin- and AdTGFβ-induced remodeling, α-SMA, caspase activation, FAS S-glutathionylation, and total protein S-glutathionylation. Four hours after administration of 50 mg/kg TLK117, GSTP activity is strongly decreased and remains decreased by about 60% for at least 24 hours[2].

Kinase Assay
[2]

The potency of TER 117 in the inhibition of GST P1-1/Ile-105 and GST P1-1/Val-105 is determined by means of GSH competition experiments using 1 μM TER 117 and three different fixed concentrations of GSH: 0.2, 0.6, and 2.0 mM. The concentration of the second substrate, 1-chloro-2,4-dinitrobenzene (CDNB) ranged between 0.15 and 1.8 mM. In addition, the inhibitor is tested at different concentrations, 0 to 8 μM, at a CDNB concentration of 1 mM and the above GSH concentrations. Initial velocities are determined spectrophotometrically at 30°C. The conjugation reaction between GSH and CDNB is monitored at 340 nm in 1 mL of 0.1 M sodium phosphate, pH 7.0[2].

Animal Administration
[1]

Mice[1]

TLK117 is administered oropharyngeally at a dose of 50 mg/kg in a 0.375 M Tris-HCl solution, pH =7.4, with 0.02% DMSO. This Tris-HCl/DMSO solution is used as a vehicle control. Treatments are performed once every 3 days from day 14 to day 26 in both >bleomycin and AdTGFβ models
