生物活性

Phloretin (NSC 407292; RJC 02792) is a flavonoid extracted from Malus pumila Mill., has anti-inflammatory activities. Phloridzin is a specific, competitive and orally active inhibitor of sodium/glucose cotransporters in the intestine (SGLT1) and kidney (SGLT2). Phloretin inhibits Yeast-made GLUT1 as well as Human erythrocyte GLUT1 with IC₅₀values of 49 μM and 61 μM, respectively.Phloretin has the potential for the treatment of rheumatoid arthritis (RA) and allergic airway inflammation.

体外研究(In Vitro)

Phloretin induced obvious cytotoxicity against BEL-7402 cells with IC₅₀ of 89.23 μM.
Phloretin (40-160 μM; 24 hours) induces BEL-7402 cell apoptosis though the mitochondrial pathway, the cells exposed to phloretin exhibits nuclear chromatin condensation and increased fluorescence intensity. The caspase-9 reaches the peak level at 12 h, and leak levels of caspase-6 and caspase-3 activities occurrs 18 and 24 h after the exposure, respectively.
Phloretin (0-100 μM; 24 hours) has effects on transcription factors of adipogenesis in differentiated 3T3-L1 adipocytes, decreases PPAR-γ, C/EBPα and C/EBPβ as a dose-dependent manner.
Phloretin (0-100 μM; 24 hours) has effects on the AMPK pathway in differentiated 3T3-L1 adipocytes, increases the phosphorylation of substrate ACC-1, AMPK in PT-treated cells.

Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
