Flavanomarein
Based on 1 Customer Validation
Flavanomarein is a substance with cytoprotective, anti-inflammatory and antioxidant activities, with a Ka of 3.064e-5 M against human Syk. Flavanomarein enhances the phosphorylation level of AKT, regulates the expression of PKC-δ, P85α, PKC-β1, Sirt1, Bcl-2 and ICAD, and inhibits the nuclear translocation of NF-κB p65. Flavanomarein regulates EMT marker proteins, promotes the proliferation of HK-2 cells, and protects neuronal cells from 6-OHDA-induced neurotoxic damage. Flavanomarein can be used in studies related to Parkinson's disease and diabetic nephropathy.

In Vitro
Flavanomarein (1.25-100 μM; 24 h preincubation followed by 24 h 6-OHDA treatment) protects PC12 cells from 6-OHDA-induced neurotoxicity by upregulating the PI3K/AKT signaling pathway, attenuating the NF-κB signaling pathway, preserving mitochondrial function, and inhibiting apoptosis, with significant effects observed at concentrations of 1.25, 25, 50, and 100 μM after 24 h preincubation[1].
Flavanomarein (1.25-100 μM; 24 h preincubation followed by 6 h 6-OHDA treatment) protects primary rat cortical neurons from 6-OHDA-induced apoptosis and cytotoxicity, with significant effects observed at concentrations of 1.25, 25, 50, and 100 μM after 24 h preincubation followed by 6 h 6-OHDA treatment[1].
Flavanomarein (200-400 μM; 24 h; 100-400 μM; 48 h) significantly promotes the proliferation of normal glucose-cultured HK-2 cells[2].
Flavanomarein (1-200 μM; 48 h) dose-dependently increases the viability of HG-stimulated HK-2 cells, reversing HG-induced cell viability reduction[2].
Flavanomarein (100 μM; 48 h) inhibits HG-induced EMT morphological changes in HK-2 cells[2].
Flavanomarein (1-80 μM; 48 h) dose-dependently enhances E-cadherin expression and reduces α-SMA, Vimentin, and FN expression in HG-stimulated HK-2 cells, exerting an anti-EMT effect[2].
Flavanomarein directly binds to Syk with high affinity, as indicated by a CDOCKER interaction energy of -75.1069 kcal/mol and specific hydrogen bonding with key Syk residues[2].
Flavanomarein (6.25-200 μM; real-time binding detection) directly binds to Syk in a concentration-dependent manner with an equilibrium dissociation constant of 3.064 × 10-5 M, confirming Syk as a direct target[2].
Flavanomarein (80 μM; 48 h) enhances E-cadherin expression and reduces α-SMA, Vimentin, and FN expression in HG-stimulated HK-2 cells, with synergistic effects when combined with a Syk inhibitor[2].
Flavanomarein (80 μM; 48 h) inhibits activation of the Syk/TGF-β1/Smad signaling pathway in HG-stimulated HK-2 cells, reducing levels of p-Syk, p-Smad2, TGF-β1, and Smad4[2].
