* <1 mg/ml means slightly soluble or insoluble.
* Please note that Selleck tests the solubility of all compounds in-house, and the actual solubility may differ slightly from published values. This is normal and is due to slight batch-to-batch variations.

Biological Activity

Description

Isoquercitrin (Hirsutrin, 3-Glucosylquercetin, Quercetin 3-o-glucopyranoside), a flavonoid compound with anticancer activity isolated from Bidens bipinnata L, is an inhibitor of Wnt/β-catenin that acts downstream of the β-catenin nuclear translocation.

Targets

Wnt/β-catenin ^[1]

In vitro

Isoquercitrin exerts inhibitory effect on Wnt/β-catenin signaling and no toxic effects on colon cancer cell lines. It supresses the proliferation of colon cancer cells but does not affect non-tumoral colon cells. Isoquercitrin inhibits cell migration in colon cancer cells, but has also no apparent effect on the non-tumor colon cells. Isoquercitrin inhibits the signaling downstream of β-catenin nuclear translocation as isoquercitrin reverses the effect of β-catenin S33A, which cannot be phosphorylated and avoids degradation^[1].

In vivo

Isoquercitrin treatment significantly affects Xenopus embryo development, most likely by disturbing axial patterning. Isoquercitrin affects canonical Wnt signaling downstream of β-Catenin nucleus translocation^[1]. In animals receiving isoquercitrin, eosinophil counts are lower in the bronchoalveolar lavage fluid (BALF), blood and lung pa-renchyma. Neutrophil counts in blood and IL-5 levels in lung homogenate are lower in isoquercitrin-treated mice. No alterations in mononuclear cell numbers are observed. Isoquercitrin also demonstrates anti-asthmatic activity by inhibiting of carbachol- and leukotriene D4-induced contraction in guinea pig airways^[2].

Protocol (from reference)

Cell Assay:^{^[1]}	Cell lines HCT-116 cells Concentrations 75 and 150 μM Incubation Time 24 h Method HCT-116 cells are treated with flavonoid isoquercitrin for 24 h at concentrations of 75 and 150 μM. DMSO (used as a vehicle to solubilize the flavonoids) is added to control cultures at 1% v/v. To stimulate the Wnt pathway, cells are treated with Wnt3a-conditioned medium (CM) for 6 h at 25% of conditioned medium. Cells are co-treated with Wnt3a-CM and isoquercitrin for 6 h at 75 or 150 μM.
