The purpose of the present study was to examine the pharmacokinetic characteristics of erianin (2-methoxy-5-[2-(3,4,5-trimethoxyphenyl)-ethyl]-phenol, CAS 95041-90-0), a nature product extracted from Dendrobium chrysotoxum, having notable antitumour activity, after intravenous injection of erianin fat emulsion to beagle dogs. An HPLC-MS method was developed to analyze the erianin levels in dog plasma and validated in a pharmacokinetic study. Plasma profiles were obtained after intravenous injection of erianin fat emulsion at the doses 7.5, 15 and 30 mg/kg. The elimination half-life (t(1/2)) values for erianin were estimated to be 1.41+/- 0.31, 1.66 +/- 0.19, 1.60 0.28 h, while the mean area under concentration-time curve (AUC(0-infinity)) values were 1021.3 +/- 373.7, 2305.1 +/- 597.0 and 3952.1 +/- 378.2 ng x h/ml, respectively. In conclusion, the present observations indicated that erianin plasma concentrations were clearly dose-proportional for the dose range studied. There was no gender difference in pharmacokinetics for erianin in male and female dogs.

With continuous emergence and widespread of multidrug-resistant Staphylococcus aureus infections, common antibiotics have become ineffective in treating these infections in the clinical setting. Anti-virulence strategies could be novel, effective therapeutic strategies against drug-resistant bacterial infections. Sortase A (srtA), a transpeptidase in gram-positive bacteria, can anchor surface proteins that play a vital role in pathogenesis of these bacteria. SrtA is known as a potential antivirulent drug target to treat bacterial infections. In this study, we found that erianin, a natural bibenzyl compound, could inhibit the activity of srtA in vitro (half maximal inhibitory concentration?IC50 = 20.91 ± 2.31 μg/mL, 65.7 ± 7.2 μM) at subminimum inhibitory concentrations (minimum inhibitory concentrations?MIC = 512 μg/mL against S. aureus). The molecular mechanism underlying the inhibition of srtA by erianin was identified using molecular dynamics simulation: erianin binds to srtA residues Ile182, Val193, Trp194, Arg197, and Ile199, forming a stable bond via hydrophobic interactions. In addition, the activities of S. aureus binding to fibronectin and biofilm formation were inhibited by erianin, when co-culture with S. aureus. In vivo, erianin could improve the survival in mice that infected with S. aureus by tail vein injection. Experimental results showed that erianin is a potential novel therapeutic compound against S. aureus infections via affecting srtA.

In this study, high-efficient phenol-degrading bacterium Bacillus sp. SAS19 which was isolated from activated sludge by resuscitation-promoting factor (Rpf) addition, were immobilized on porous carbonaceous gels (CGs) for phenol degradation. The phenol-degrading capabilities of free and immobilized Bacillus sp. SAS19 were evaluated under various initial phenol concentrations. The obtained results showed that phenol could be removed effectively by both free and immobilized Bacillus sp. SAS19. Furthermore, for degradation of phenol at high concentrations, long-term utilization and recycling were more readily achieved for immobilized bacteria as compared to free bacteria. Immobilized bacteria exhibited significant increase in phenol-degrading capabilities in the third cycle of recycling and reuse, which demonstrated 87.2% and 100% of phenol (1600?mg/L) degradation efficiency at 12 and 24?h, respectively. The present study revealed that immobilized Bacillus sp. SAS19 can be potentially used for enhanced treatment of synthetic phenol-laden wastewater.
