Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Barley maiya from gramineous plants (Hordeum vulgare L.) is obtained from ripe fruits through germination and drying. It is often used to treat diseases associated with high prolactin levels. OBJECTIVE To investigate the anti-hyperprolactinemia (anti-HPRL) mechanisms of total barley maiya alkaloids (TBMA) and hordenine. METHODS This experiment included 9 groups: Normal group, TBMA group, hordenine group, TBMA + haloperidol group, TBMA + forskolin group, TBMA + 8-bromo-cAMP group, hordenine + haloperidol group, hordenine + forskolin group, and hordenine + 8-bromo-cAMP group. The prolactin (PRL) concentration in the supernatant and the total cAMP concentration in the cells were detected by ELISA. The expression levels of PRL, dopamine D2 receptor (DRD2) and cAMP/PKA/CREB protein were measured by Western Blot. RESULTS In the TBMA group and the hordenine group, the PRL level in MMQ cells was significantly decreased, but in GH3 cells there was no change. DRD2 expression level was markedly increased, cAMP concentration was decreased, and the activity of PKA and CREB declined in MMQ cells. Compared with the TBMA group, there was a significant decrease of DRD2 expression level, a remarkable increase of PRL secretion and an increase of cAMP/PKA/CREB expression in MMQ cells within the TBMA + haloperidol group. Compared with the forskolin group, there was no significant change in PRL secretion and cAMP/PKA/CREB expression level in MMQ cells within the TBMA + forskolin group. There was a decrease in PRL secretion and cAMP/PKA/CREB expression level in MMQ cells within the TBMA + 8-bromo-cAMP group compared with the 8-bromo-cAMP group. Compared with the hordenine group, DRD2 expression level was significantly decreased, PRL secretion was markedly increased, and cAMP/PKA/CREB expression level was increased in MMQ cells within the hordenine + haloperidol group. There was no significant change in PRL secretion and cAMP/PKA/CREB expression level in MMQ cells within the hordenine + forskolin group compared with the forskolin group and within the hordenine + 8-bromo-cAMP group compared with the 8-bromo-cAMP group. CONCLUSION TBMA and hordenine can both play an anti-HPRL role via DRD2, and TBMA can also act on PKA targets to exert its anti-HPRL effect. TBMA and hordenine may be potential treatment strategies for HPRL.

Abstract
The objective of this paper was to extend comprehensive theoretical and experimental investigations at the molecular level to identify factors responsible for the high selectivity of imprinted sorbents. This knowledge was utilized in a new analytical strategy devoted to the analysis of hordenine in human urine after beer consumption. Among the various polymeric compositions tested, the most effective material was built up from methacrylic acid and ethylene glycol dimethacrylate (MIP1), showing a satisfactory binding capacity (4.44 ± 0.15 µmol g-1) and high specificity towards hordenine (AF = 5.90). The comprehensive analyses of porosity data and surface measurements revealed differences between imprinted polymers. The characterization of binding sites of MIP1 revealed a heterogeneous population with two values of Kd (2.75 and 370 μmol L-1) and two values of Bmax (1.82 and 99 μmol g-1) for higher and lower affinity respectively. The extensive theoretical analyses of interactions between various analytes and the MIP model cavity showed the highest binding energy for hordenine (ΔEB1 = -175.17 kcal mol-1). The method was validated for selectivity, lowest limit of quantification, calibration curve performance, precision, accuracy, matrix effect, carry-over and stability in urine. Extracts were prepared according to guidelines of the European Medicines Agency. The validation criteria were fulfilled, and the method was satisfactorily applied to urine samples collected prior to, and 2 h after, consumption of 2 L of beer, revealing the presence of hordenine at the mean level of 129 ± 27 ng mL-1. Additionally, ability of the sorbent to purify the urine sample was assessed using flow injection analysis tandem mass spectrometry, for comparison with other extraction techniques.

Abstract
Proton magnetic resonance-based metabolomics analysis was performed to determine the global metabolite changes in pathogenic bacterium Pseudomonas aeruginosa PAO1 following exposure to quorum sensing (QS) inhibitor hordenine. Pyocyanin inhibition assay confirmed that hordenine exhibited potent QS inhibitory activity. A total of 40 metabolites were assigned by PMR spectra. Hordenine treatment resulted in the destruction of QS system in P. aeruginosa PAO1 by downregulating the expressions of genes involved in QS. The synthesis of antioxidant enzymes was repressed and the oxidative stress was enhanced due to the dysfunctional QS system of P. aeruginosa PAO1. The enhanced oxidative stress induced by the dysfunctional QS system of P. aeruginosa PAO1 altered the membrane components, enhanced membrane permeability, and disturbed energy metabolism, amino acid metabolism, and nucleotide metabolism, and would ultimately attenuate the pathogenicity of P. aeruginosa PAO1. Hordenine may have promising potential for controlling nosocomial pathogens.

Abstract
The worldwide prevalence of diabetes and associated metabolic diseases has dramatically increased. Pharmacological treatment of diabetes is still limited. Hordenine (HOR), a phenethylamine alkaloid, is a natural constituent in many plants. The present study was designed to explore the possible anti-diabetic effect of HOR in streptozotocin (STZ)-induced diabetic mice. Combined treatment of HOR and insulin significantly reduced fasting and postprandial blood glucose level in diabetic mice. HOR and insulin did not show evident protective effect against structural and functional injuries of pancreas. Renal histological and functional injuries were significantly improved by HOR or insulin treatment. Moreover, combined treatment of HOR and insulin resulted in a more significant amelioration of renal histological and functional injuries in diabetic mice. HOR induced a decrease of renal IL-1α/β and IL-6 expression, and a reduction of Col1α1 and MMP9 expression and PAS-stained mesangial expansion in glomeruli of diabetic mice. In diabetic mice, HOR significantly decreased Nrf2 expression and increased hnRNPF and hnRNPK expression in kidney. Moreover, HOR showed a synergistic effect with insulin on the expression of these regulators. Renal ROS level and TBARS content in diabetic mice were decreased by HOR. The reduction of renal expression of antioxidant enzymes in diabetic mice was inhibited by HOR and insulin. Furthermore, HOR and insulin function synergistically to play an antioxidant role against oxidative injury in diabetic nephropathy. In conclusion, to the best of our knowledge, we, for the first time, found the anti-diabetic, anti-inflammatory, and anti-fibrotic role of HOR in combination with insulin. HOR functions synergistically with insulin and prevents diabetic nephropathy. However, the molecular mechanism of the synergistic effect of HOR and insulin needs to be elucidated.
