Coixol (6-Methoxy-2-benzoxazolinone)

Coixol is a natural product extracted from Coix Lachryma-Jobi var. ma-yuen.IC50 value:Target:In vitro: Confluent NCI-H292 cells were pretreated with oleic acid, linoleic acid, glyceryl trilinoleate, beta-stigmasterol or coixol for 30 min and then stimulated with PMA (phorbol 12-myristate 13-acetate), EGF (epidermal growth factor) or TNF-α (tumor necrosis factor-α) for 24 h. Coixol inhibited the expression of MUC5AC mucin gene and production of MUC5AC mucin protein, induced by EGF or TNF-α from NCI-H292 cells; Coixol decreased PMA-induced MUC5AC mucin secretion from NCI-H292 cells [1]. βTC-6 cells were incubated in 2 mM and 20 mM glucose in thepresence of coixol (200 μM) for 60 min at 37°C in Krebs-RingerBicarbonate buffer. Decreased insulin staining was observed by coixol at 20 mM glucose (bottom) suggest that coixol stimulated insulin secretion at high glucose concentration [2].In vivo:
