Biological target:
Inflachromene, a microglial inhibitor, binds to HMGB1 and HMGB2 and exerts anti-inflammatory effects. Inflachromene effectively downregulates proinflammatory functions of HMGB and reduces neuronal damage. Inflachromene can be used for the research of neuroinflammatory disorders.
In vitro activity:
The total HMGB2 protein (Fig. 5A, left) was decreased by ICM (inflachromene) in CGR8 cells, which was in agreement with the report that ICM modified HMGB2 protein stability but not mRNA expression
Reference: Hepatol Commun. 2017 Oct;1(8):816-830. https://pubmed.ncbi.nlm.nih.gov/29218329/
In vivo activity:
ICM (inflachromene) treatment greatly reduced not only surface tumours (Fig. 7c and Extended Data Fig. 9b), but also microscopic lesions in DEN/Cre mice (Fig. 7d and Extended Data Fig. 9c). Indeed, ICM treatment significantly attenuated liver fibrosis in DEN/Cre livers, as supported by decreased fibrotic gene expression and collagen deposition (Fig. 7h and Extended Data Fig. 9l).

Note: There can be variations in solubility for the same chemical from different vendors or different batches from the same vendor. The following factors can affect the solubility of the same chemical: solvent used for crystallization, residual solvent content, polymorphism, salt versus free form, degree of hydration, solvent temperature. Please use the solubility data as a reference only. Warming and sonication will facilitate dissolving. Still have questions? Please contact our Technical Support scientists.
