Inhibition of VHR dual-specificity protein tyrosine phosphatase activity by flavonoids isolated from Scutellaria baicalensis: structure-activity relationships.

Ainult registreeritud kasutajad saavad artikleid tõlkida

Logi sisse

Three flavonoids: norwogonin, dihydronorwogonin and baicalein, were isolated from the roots of Scutellaria baicalensis, as potential inhibitors of VHR dual-specificity protein tyrosine phosphatase (DS-PTPase). Norwogonin (IC 50 = 1.1 microM), dihydronorwogonin (IC 50 = 2.9 microM) and baicalein (IC

Baicalein and scutellarein are bioactive flavones found in the medicinal plant Scutellaria baicalensis Georgi, used in traditional Chinese medicine. Extensive previous work has demonstrated the broad biological activity of these flavonoids, such as antifibrotic, antiviral and anticancer properties.

Baicalein attenuates α-synuclein aggregation, inflammasome activation and autophagy in the MPP+-treated nigrostriatal dopaminergic system in vivo.

Imatinib (IM), as first inhibitor of the oncogenic tyrosine kinase BCR-ABL, has been widely used to treat chronic myeloid leukemia (CML) for decades in clinic. However, resistance to IM usually occurs in CML patients. The bone marrow (BM), as the predominant microenvironment of CML, secretes an

Parkinson's Disease (PD) is the second most common neurodegenerative disease with the clinical characteristics of gait deficits. The classical symptomatic treatment for PD is Levodopa (L-DOPA) which brings a plethora of side effects and dosage problems in a prolonged drug regimen. Baicalein is a

Flavonoids are structurally similar to steroid hormones, particularly estrogens, and therefore have been studied for their potential effects on hormone-dependent cancers. Baicalein is the primary flavonoid derived from the root of Scutellaria baicalensis Georgi. In the present study, we investigated

Bone marrow microenvironment confers imatinib resistance to chronic myelogenous leukemia and oroxylin A reverses the resistance by suppressing Stat3 pathway.

Imatinib (IM) is highly effective in treatment of chronic myeloid leukemia (CML) but does not eliminate minimal residual disease (MRD), which remains a potential source of relapse. IM treatment effectively inhibits BCR-ABL kinase activity in CML cells, suggesting that additional kinase-independent
