| Hazard Information | Back Directory | [Chemical Properties]
Orange-yellow crystalline powder, soluble in organic solvents such as methanol, ethanol, and DMSO, derived from Cassia seed. | [Uses]
Obtusifolin, isolated from the seeds of Cassia obtusifolia, regulates the gene expression and production of MUC5AC mucin in airway epithelial cells via inhibiting NF-kB pathway[1]. Obtusifolin suppresses phthalate esters-induced breast cancer bone metastasis by targeting parathyroid hormone-related protein[2]. | [Definition]
ChEBI: Obtusifolin is a dihydroxyanthraquinone. | [General Description]
This substance is a primary reference substance with assigned absolute purity (considering chromatographic purity, water, residual solvents, inorganic impurities). The exact value can be found on the certificate. Produced by PhytoLab GmbH & Co. KG | [IC 50]
