Background:

8-Oxycoptisine is an isoquinoline alkaloid that has been found inCoptis chinensisand has anticancer and gastroprotective activities.^1,2,3It is an active metabolite of coptisine formed by gut microbiota.¹8-Oxycoptisine is cytotoxic against NCI-N87 gastric, but not Caco-2 colon, cancer cells (IC₅₀s = 20.31 and >100 µM, respectively).²It reverses resistance to paclitaxel in non-multidrug-resistant SKOV3 cells, as well as in HCT-15 cells, which endogenously express high levels of P-glycoprotein (P-gp), with EC₅₀values of 0.3 and 0.5 ng/ml, respectively.³It reduces colonic shortening and inflammatory cell infiltration in a mouse model of ulcerative colitis induced by dextran sulfate when administered at doses of 50 or 100 mg/kg.¹
