Guavinoside B
Guavinoside B is an orally active α-glucosidase inhibitor with an IC50 of 0.21 mM. Guavinoside B upregulates the expressions of Nrf2, GCLC and NQO1 induced by Acetaminophen (HY-66005), downregulates the expression of p-JNK, and reduces intracellular ROS levels. Guavinoside B decreases serum TNF-α levels induced by Acetaminophen, alleviates hepatocellular infiltration and necrosis, and improves liver-related biochemical parameters. Guavinoside B is applicable to the research of diabetes and Acetaminophen-induced liver injury.

Guavinoside B potently inhibits purified α-glucosidase enzyme activity with an IC50 of 0.21 mM[1].
Guavinoside B (3.3-100 μM; 24 h) does not affect the viability of HepG2 cells, either with or without 5 mM Acetaminophen (HY-66005) treatment[2].
Guavinoside B (3.3-30 μM; 16 h) reduces Acetaminophen-induced intracellular ROS accumulation by 28.6% in HepG2 cells, with weaker, non-significant effects at 3.3 and 10 μM[2].
Guavinoside B (10-30 μM; 16 h) upregulates Nrf2 and GCLC mRNA expression in untreated HepG2 cells, and (3.3-30 μM; 16 h) upregulates Nrf2, GCLC, and NQO1 mRNA expression in Acetaminophen-treated HepG2 cells[2].
