The study was designed as one of a series to find novel anticancer compounds from Chinese herbs. For this purpose, we screened an ethanol extract of 300 herbs against SGC-7901 cells. Sophora flavescen was included in those showing potential cytotoxic activity. Target compounds were therefore
Kurarinone is a prenylated flavonone isolated from the roots of Sophora flavescens. Among its known functions, kurarinone has both anti-apoptotic and anti-inflammatory properties. Coronaviruses (CoVs), including HCoV-OC43, SARS-CoV, MERS-CoV, and SARS-CoV-2, are the causative agents of
Our previous study showed that kurarinone was the main hepatotoxic ingredient of Sophora flavescens, accumulating in the liver. This study characterized the mechanism of Sophora flavescens extract (ESF) hepatotoxicity and hepatic accumulation of kurarinone. ESF impaired hepatic function and caused
The accumulation of circulating monocytes in the arterial wall is an early in atherosclerotic plaque formation. Monocyte chemoattractant protein-1 (MCP-1) promotes the migration of monocytes and would play a role in the development of atherosclerotic lesions. Searching for inhibitors of
We have analyzed in molecular detail how kurarinone, a lavandulyl flavanone isolated from Sophora flavescens, suppresses nuclear factor-κB (NFκB)-driven interleukin-6 (IL6) expression and cancer cell growth. Interleukin-6 (IL6), involved in cancer-related inflammation, acts as an autocrine and
Kurarinone is a major component found in the dried roots of Sophora flavescens Ait. that participates in vital pharmacological activities. Recombinant CYP450 supersomes and liver microsomes were used to study the metabolic profiles of kurarinone and its inhibitory actions against cytochrome
Kurarinone, a natural prenylated flavonone isolated from Sophora flavescens, has been exhibited various activities. This study aimed to establish a simple and sensitive ultra-high performance liquid chromatography-tandem mass spectrometry (UHPLC-MS/MS) method for determining kurarinone in dog
The large-conductance calcium-activated potassium channel (BKCa channel) plays critical roles in smooth muscle relaxation. In urinary bladder smooth muscle, BKCa channel activity underlies the maintenance of the resting membrane potential and repolarization of the spontaneous action potential
Kurarinone, a lavandulyl flavanone, was isolated from a polyphenolic extract of the roots of Sophora flavescens using fractionation guided by estrogenic activity, which was determined by recombinant yeast and Ishikawa Var-I bioassays. Kurarinone showed weak estrogenic activity both in the yeast
In response to cellular stresses, activating transcriptional factor 4 (ATF4) regulates the expression of both stress-relieving genes and apoptosis-inducing genes, eliciting cell fate determination. Since pharmacological activation of ATF4 exerts potent anti-tumor effects, modulators of ATF4
BACKGROUND
Kurarinone, the most abundant prenylated flavonoid in Sophora flavescens Aiton (Leguminosae), is a promising antitumor therapeutic. However, it shows significant hepatotoxicity. Furthermore, how kurarinone is metabolized in humans remains unclear.
OBJECTIVE
The objective of this study is
Kurarinone, a flavonoid isolated from Sophora flavescens Aiton, has been reported to have significant antitumor activity. However, the cytotoxic activity of kurarinone against non-small cell lung cancer (NSCLC) cells is still under explored. In our study, we have evaluated the inhibitory effects of
Kurarinone, a flavonoid isolated from the roots of Sophora flavescens, was suggested to exert potent antioxidant and immunosuppressive effects. However, the underlying mechanisms remain unclear. Nuclear factor erythroid 2-related factor 2 (Nrf2) is a key transcription factor that regulates
Sophora flavescens is a medicinal herb that contains flavonoids and quinolizidine alkaloids and has a wide range of biological activities due to its anti-inflammatory, anti-bacterial and anti-cancer properties. We isolated a series of flavonoids from the roots of Sophora flavescens and examined
This study aimed to develop and validate a simple and sensitive ultra high performance liquid chromatography tandem mass spectrometry method for the simultaneous determination of sophoraflavanone G and kurarinone in rat plasma by using rutin as the internal standard. Then, the developed method was
