EGR240 (ERG240) is an orally active, selective inhibitor of branched-chain amino acid transaminase 1 (BCAT1) with an IC₅₀ of 0.1–1nM[1-2]. EGR240 is suitable for research in cancer, rheumatoid arthritis, and bone diseases[3-4].
In vitro, THP-1 macrophages were pretreated with EGR240 (20μM) for 3 hours, followed by LPS (200ng/mL) and Nigericin (10μM) to induce pyroptosis. EGR240 significantly suppressed BCAT1-mediated NF-κB signaling activation and reduced the secretion of key pyroptosis-related proteins, GSDMD-NT and IL-1β[5]. Ovarian cancer persistent cells (OVCAR8-Persister and A2780-Persister) were treated with EGR240 (60μM) for 24 hours. EGR240 did not significantly affect cell viability, and EGR240 combination with paclitaxel did not enhance paclitaxel cytotoxicity[6].
In vivo, collagen-induced arthritis mice were orally administered EGR240 (720–1000mg/kg). EGR240 significantly alleviated arthritis severity, reducing joint inflammation, pannus formation, cartilage degradation, and bone erosion[7]. db/db diabetic retinopathy mice received intravitreal injections of EGR240 (100–200μM; 1μL) for 2 or 4 weeks. EGR240 significantly downregulated retinal inflammatory gene mRNA expression, such as Gfap and Il6, and reduced retinal vascular leakage[8].

| Cell experiment [1]: | |
Cell lines | THP-1 macrophages (human monocytic cell line) |
Preparation Method | THP-1 cells were differentiated into macrophages using PMA (50ng/mL) for 48 hours, followed by priming with LPS (200ng/mL, 4 hours) and Nigericin (10μM, 30 minutes) to induce pyroptosis. Cells were pretreated with EGR240 (20μM) for 3 hours prior to LPS/Nigericin stimulation. |
Reaction Conditions | 20µM; 3-hour pretreatment. |
Applications | EGR240 significantly suppressed BCAT1-mediated NF-κB activation, reduced phosphorylation of p65, and attenuated pyroptosis execution by decreasing cleavage of GSDMD and caspase-1. EGR240 also inhibited IL-1β and TNF-α secretion in cell supernatants and preserved cell membrane integrity by reducing pyroptosis-associated pore formation. |
| Animal experiment [2]: | |
Animal models | db/db diabetic mice (C57BL/6J background) and WT mice. |
Preparation Method | Mice received intravitreal injections of EGR240 (100μM or 200μM; 1μL) under anesthesia with ketamine (80mg/kg) and xylazine (4mg/kg). Injections were administered weekly for 2 or 4 weeks. Retinal tissues and plasma were collected for analysis. |
Dosage form | 100–200μM of 1μL; intravitreal injection; weekly for 2–4 weeks. |
Applications | EGR240 significantly reduced retinal inflammatory gene expression (Gfap and Il6) and attenuated vascular leakage in diabetic retinas. EGR240 suppressed BCAT1-mediated metabolic reprogramming and epigenetic activation of inflammation by restoring α-KG levels, thereby mitigating diabetic retinopathy progression. |
