生物活性

Palmatine chloride is an orally active and irreversible indoleamine 2,3-dioxygenase 1 (IDO-1) inhibitor. Palmatine chloride can ameliorate DSS-induced colitis by mitigating colonic injury, preventing gut microbiota dysbiosis, and regulating tryptophan catabolism. Palmatine has the potential for colitis treatment[1].

IC50 & Target[1]

IDO1

 

体外研究
(In Vitro)

Palmatine exhibits more potent IDO-1 inhibitory activity , which IC50 on rhIDO-1 is 157 μM, and on HEK 293-hIDO-1 is 3 μM[1].

体内研究
(In Vivo)

Palmatine (oral administration; 50 or 100 mg/kg, 7 days) has less distortion of epithelium, and fewer infiltrations of inflammatory cells, resulting in significantly lower histopathological scores, it also significantly suppresses the colonic MPO activity[1].

Animal Model: DSS- induced Colitis BALB/c mice model[1]
Dosage: 50 or 100 mg/kg; 7 days
Administration: Oral administration
Result: Ameliorated DSS-induced colitis and prevented infiltration of inflammatory cells.
