Oxyberberine
Based on 2 publication(s) in Google Scholar
Oxyberberine (Oxyberberin; Berlambine) is an orally effective heme oxygenase HO-1 agonist that can activate antioxidant mechanisms by regulating the PI3K/Akt/AMPK signaling pathway. Oxyberberine induces HO-1 expression, increases SOD and GSH-Px activity, inhibits NF-κB-mediated inflammatory responses, and improves insulin sensitivity and glucose metabolism. Oxyberberine has anti-diabetic, neuroprotective, anti-inflammatory and antioxidant effects, and can be used to study type 2 diabetes, traumatic brain injury (TBI) and inflammatory bowel disease.

Oxyberberine (5-20 μM; 24-48 h) promotes glucose-stimulated insulin secretion in INS-1 cells, reduces intracellular reactive oxygen species (ROS) and malondialdehyde (MDA) levels, and increases superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities[1].
Oxyberberine (10-40 μM; 24 h) enhances glucose consumption, upregulates phosphorylated Akt (p-Akt) and GSK-3β (p-GSK-3β) expressions, and downregulates glucose-6-phosphatase (G6Pase) and phosphoenolpyruvate carboxykinase (PEPCK) levels in insulin-resistant HepG2 cells[1].

-
Cell Line:INS-1 cells
-
Concentration:5, 10, 20 μM
-
Incubation Time:48 h
-
Result:Dose-dependently increased insulin secretion in high-glucose (25 mM) stimulated INS-1 cells, reduced oxidative stress markers (NO, MDA) and increased antioxidant enzymes (SOD, GSH-Px).
Co-treatment with HO-1 inhibitor ZnPP reversed these effects, indicating dependency on HO-1 activation.
-
Cell Line:Insulin-resistant HepG2 cells
-
Concentration:10, 20, 40 μM
-
Incubation Time:24 h
-
Result:Significantly increased glucose consumption in insulin-resistant HepG2 cells.
Western blot analysis showed upregulation of p-Akt, p-GSK-3β and downregulation of G6Pase, PEPCK, with the most pronounced effects at 40 μM.
Co-administration of ZnPP attenuated these changes, suggesting involvement of HO-1 signaling.
Oxyberberine can significantly alleviate DSS-induced ulcerative colitis in mice, which may be related to the inhibition of TLR4/Myd88/NF-κB pathway excitation and regulation of intestinal flora. LD50 >5000 mg/kg. Oxyberberine (12.5-50 mg/kg; intraperitoneal injection; once daily; 21 days) significantly improves colon tissue pathological damage in the TNBS-induced rat colitis model, reduces the proinflammatory markers TNF-α, IL-2, IL-8 and IL-22, and increases the levels of IL-4 and IL-13[2].
Oxyberberine (25, 50 mg/kg; intraperitoneal injection; once daily; 21 days) alleviates neurological deficits, improves anxiety-like behaviors and cognitive impairment in the traumatic brain injury (TBI) model of male C57BL/6 mice, and inhibits the HMGB1-mediated TLR4/NF-κB inflammatory pathway in brain tissue[3].

-
Animal Model:Male Sprague-Dawley rats (220-240 g, 7-week-old) with high-fat diet/streptozotocin (HFD/STZ)-induced type 2 diabetes[1]
-
Dosage:50 mg/kg, 100 mg/kg (saline)
-
Administration:Oral gavage, once daily, for 6 weeks
-
Result:Significantly decreased fasting blood glucose (FBG), triglyceride (TG), total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and glycosylated serum protein (GSP), while increasing high-density lipoprotein cholesterol (HDL-C).
Improved insulin sensitivity (reduced HOMA-IR), pancreatic antioxidant capacity (increased SOD, GSH-Px), and attenuated islet cell apoptosis and inflammatory cytokine levels (TNF-α, IL-6).
Co-treatment with HO-1 inhibitor ZnPP reversed these effects.
-
Animal Model:Male C57BL/6 mice (6-8-week-old) with traumatic brain injury (TBI)-induced traumatic brain injury[3]
-
Dosage:25 mg/kg, 50 mg/kg (saline)
-
Administration:Intraperitoneal injection, once daily, for 21 days
-
Result:Significantly reduced neurological severity scores (NSS) and improved motor coordination in rotarod tests.
Decreased anxiety-like behavior in elevated zero maze (EZM) and improved cognitive performance in novel object recognition task (NORT).
Western blot showed reduced expression of HMGB1, TLR4, and NF-κB in ipsilateral cortex, with the highest efficacy at 50 mg/kg.
