Phloretin (NSC 407292; RJC 02792) is a flavonoid extracted fromMalus pumilaMill., has anti-inflammatory activities. Phloridzin is a specific, competitive and orally active inhibitor ofsodium/glucose cotransportersin the intestine (SGLT1) and kidney (SGLT2). Phloretin inhibits Yeast-madeGLUT1as well as Human erythrocyteGLUT1withIC₅₀values of 49 μM and 61 μM, respectively^[1].Phloretin has the potential for the treatment of rheumatoid arthritis (RA) and allergic airway inflammation^[4].

Phloretin induced obvious cytotoxicity against BEL-7402 cells with IC₅₀of 89.23 μM^[2].
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^[2].
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^[3].
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^[3].

Phloretin (oral administration; 50 or 100 mg/kg; once daily) decreases oxidative stress and diminished levels of malondialdehyde (MDA) and hydrogen peroxide (H2O2) in paw tissue, reduces productivity of anti-collagen antibodies in serum^[3].
