T-5224

T-5224 is a selective inhibitor of c-Fos/activator protein (AP)-1. It also inhibits MMP3/13 with IC50s of 10 nM.

T-5224 (0-80 μM) significantly inhibits the invasion, migration, and MMP activity of HSC-3-M3 cells in a dose-dependent manner. There is no significant influence on HSC-3-M3 amd OSC-19 cells proliferation[4].

G2 is observed in rat and monkey liver microsomes as a major metabolite of T-5224, suggesting that G2 is not a human-specific metabolite[1]. T-5224 (300 mg/kg, p.o.) inhibits the production of TNF-alpha and other downstream effectors in C57BL/6 mice[2]. Administration of T-5224 (300 mg/kg, p.o.) after intraperitoneal injection of LPS impartes appreciable protection against acute elevations in serum levels of TNFα, HMGB1, ALT/AST as well as in liver tissue levels of MIP-1α and MCP-1, and reduces the lethality (27%)[3].

HSC-3-M3 cells are starved for 24 h with DMEM containing 0.5% FBS. The top chamber of the cell invasion device is coated with 50 μL of 0.1 × basement membrane extract solution and incubataed overnight. HSC-3-M3 cells (5.0 × 104 cells/well) are added to the top chamber with DMEM containing 0.5% FBS mixed with 0-80 μM T-5224; DMEM with 10% FBS is added to the bottom chamber and incubated for 48 h. The bottom plate is read using a multilabel plate reader. The data are compared with the standard curve to determine the fraction of invaded cells.

Mice in LPS group are administered orally with polyvinylpyrrolidone solution in the same volume of T-5224 solution immediately after LPS injection, while in the T-5224 group, mice are administered orally with T-5224 (300 mg/kg, p.o.) in the same manner. In the control group, mice receives polyvinylpyrrolidone solution orally soon after intraperitoneal saline injection. Blood samples are collected for each measurement at the optimal time.
