설명

일반 설명

A cell-permeable, chromene-fused benzopyran-embedded tetracyclic compound that selectively and directly binds to the DNA binding domain box A of high mobility group box (HMGB) proteins and blocks their post-translational phosphorylation and acetylation. Diminishes the cytoplasmic accumulation of HMGB2 in microglial cells. Blocks lipopolysaccharide (LPS)-induced nitrite release in BV-2 microglial cells, RAW 264.7 macrophages, and mouse primary microglial cultures (~50 nM to 20 µM) without inducing any toxicity. However, it is shown to be less potent in primary astrocytes. Suppresses LPS-stimulated increase in the levels of IL-6, IL-1b, NOS2, and TNFα genes and inhibits the nuclear translocation of NF-κB. Also shown to reduce LPS-induced phosphorylation of ERK, JNK, and p38 MAP kinases in microglia. Reduces neuroinflammation, neurite damage, and spinal cord demyelination in a murine model of auto-immune encephalitis (~10 mg/kg).

Please note that the molecular weight for this compound is batch-specific due to variable water content. Please refer to the vial label or the certificate of analysis for the batch-specific molecular weight. The molecular weight provided represents the baseline molecular weight without water.
