Comparison of the Inhibitory Potential of Bavachalcone and Corylin against UDP-Glucuronosyltransferases.[Pubmed:24829606]

Evid Based Complement Alternat Med. 2014;2014:958937.

Bavachalcone and corylin are two major bioactive compounds isolated from Psoralea corylifolia L., which has been widely used as traditional Chinese medicine for many years. As two antibiotic or anticancer drugs, Bavachalcone and corylin are used in combination with other drugs; thus it is necessary to evaluate potential pharmacokinetic herb-drug interactions (HDI) of the two bioactive compounds. The aim of the present study was to compare the effects of liver UDP-glucuronosyltransferase (UGT) 1A1, UGT1A3, UGT1A7, UGT1A8, UGT 1A10, and UGT2B4 inhibited by Bavachalcone and corylin. 4-Methylumbelliferone (4-MU) was used as a nonspecific "probe" substrate. Bavachalcone had stronger inhibition on UGT1A1 and UGT1A7 than corylin which did not inhibit UGT1A1, UGT1A3, UGT1A7, UGT1A8, UGT1A10, and UGT2B4. Data fitting using Dixon and Lineweaver-Burk plots demonstrated the noncompetitive inhibition of Bavachalcone against UGT1A1 and UGT1A7-mediated 4-MU glucuronidation reaction. The values of inhibition kinetic parameters (Ki) were 5.41 mu M and 4.51 mu M for UGT1A1 and UGT1A7, respectively. The results of present study suggested that there was a possibility of UGT1A1 and UGT1A7 inhibition-based herb-drug interaction associated with Bavachalcone and provided the basis for further in vivo studies to investigate the HDI potential between Bavachalcone and UGT substrates.

Bavachalcone-induced manganese superoxide dismutase expression through the AMP-activated protein kinase pathway in human endothelial cells.[Pubmed:25766656]

Pharmacology. 2015;95(3-4):105-10.

Mitochondrial oxidative stress has been suggested as a major etiological factor in cardiovascular diseases. Manganese superoxide dismutase (MnSOD) is an essential antioxidant mitochondrial enzyme. Although polyphenols can induce MnSOD expression, their mechanism of action remains unclear. We examined the effect of Bavachalcone, a bioactive compound isolated from Psoralea corylifolia, on MnSOD protein expression and explored whether this effect is mediated through the AMP-activated protein kinase (AMPK) signaling pathway. Our data showed that Bavachalcone enhanced the luciferase activity of the MnSOD promoter and increased MnSOD mRNA and protein expressions. Moreover, Bavachalcone suppressed the mitochondrial superoxide production in endothelial cells. Conversely, Bavachalcone stimulated liver kinase B1 and AMPKalpha phosphorylation. mRNA interference by using short hairpin RNA (shRNA) of AMPK inhibited Bavachalcone-induced MnSOD expression. A-769662, an AMPK activator, also stimulated AMPK activity and increased MnSOD expression. Furthermore, AMPK knockdown by shRNA-AMPK reversed the inhibitory effects of Bavachalcone on mitochondrial superoxide production in endothelial cells. These findings indicate that Bavachalcone can protect the endothelial function by increasing AMPK activity and MnSOD expression and reducing mitochondrial oxidative stress. .

Bavachalcone inhibits osteoclast differentiation through suppression of NFATc1 induction by RANKL.[Pubmed:18433733]

Biochem Pharmacol. 2008 Jun 1;75(11):2175-82.

Osteoclasts are cells that have a specialized role for bone resorption and are responsible for many bone diseases such as osteoporosis. As herbal products are invaluable sources in discovery of compounds for new therapies, we sought to identify compounds efficacious in suppressing osteoclastogenesis from medicinal plants that have been implicated for treatment of osteoporotic conditions. Bavachalcone was isolated from Psoralea corylifolia, and its effects on osteoclast differentiation were evaluated with primary cultures of osteoclast precursor cells. In addition, the molecular mechanism of action was investigated. Bavachalcone inhibited osteoclast formation from precursor cells with the IC(50) of approximately 1.5 microg ml(-1). The activation of MEK, ERK, and Akt by receptor activator of nuclear factor kappaB ligand (RANKL), the osteoclast differentiation factor, was prominently reduced in the presence of Bavachalcone. The induction of c-Fos and NFATc1, key transcription factors for osteoclastogenesis, by RANKL was also suppressed by Bavachalcone. In conclusion, Bavachalcone inhibits osteoclastogenesis by interfering with the ERK and Akt signaling pathways and the induction of c-Fos and NFATc1 during differentiation. Our results suggest that Bavachalcone may be useful as a therapeutic drug for bone resorption-associated diseases.
