In Vitro Isoquercitrin occurs widely in plants.10 μM of Isoquercitrin of the seven compounds partially but significantly blunt the negative effect of H2O2 on RGC-5 cells, as the viability of cells in the presence of H2O2 is increased from approximately 63% to 83% and 90% at 10 and 50 μM, respectively. Indeed, 50 μM Isoquercitrin is more effective as a neuroprotectant than the same concentration of EGCG[1].
In Vivo In animals receiving Isoquercitrin or quercetin, eosinophil counts are lower in the BALF, blood and lung parenchyma. Neutrophil counts in blood and IL-5 levels in lung homogenate are lower only in Isoquercitrin-treated mice. No alterations in mononuclear cell numbers were observed[2].
Animal Admin Mice[2] BALB/c mice are immunized (ovalbumin/aluminum hydroxide, s.c.), followed by two intranasal ovalbumin challenges. From day 18 to day 22 after the first immunization, the mice receive daily gavages of Isoquercitrin (15 mg/kg) or quercetin (10 mg/kg). Dexamethasone (1 mg/kg, s. c.) is administered as a positive control. Leucocytes are analyzed in bronchoalveolar lavage fluid (BALF), blood and pulmonary parenchyma at 24 h after the last ovalbumin challenge. Interleukin-5 (IL-5) is analyzed in BALF and lung homogenates[2].
