Abstract
Di-d-psicose anhydride (DPA), derived from functional rare saccharide as d-psicose, is investigated for its strong chelating ability. Methylglyoxal (MGO), an important precursor of advanced glycation end-products (AGEs), promotes obesity, and causes complications such as diabetic nephropathy. On mesangial cells, DPA can substantially reduce the negative effects of MGO. DPA effectively trapping MGO in mesangial cells. The bonding properties of the DPA-MGO adduct were discussed by mass spectrometry and nuclear magnetic resonance (NMR). The NMR spectra of the DPA-MGO adduct provide evidence for chelation bonding. The inhibition of AGE formation and the mass spectrometry results of the DPA-MGO adduct indicate that DPA can scavenge MGO at a molar ratio of 1:1. DPA suppressed 330 % of the up-regulated receptor for an AGEs protein expression to a normal level and restored the suppressed glyoxalase 1 level to 86 % of the normal group. This research provides important evidence and theoretical basis for the development of AGE inhibitors derived from rare saccharide.

Abstract
The thermostability of enzymes is an essential factor that performs a vital role during practical applications. Inulin fructotransferases can efficiently convert inulin into bio-functional difructose anhydrides (DFAs). The present study aimed to improve the thermostability of a previously reported inulin fructotransferase, SpIFTase, and apply it to the biosynthesis of DFA I. In silico rational design was used to predict mutation sites, based on sequential and structural information. Two triple-site mutants, Q69L/Q234L/K310G and E201I/Q234L/K310G, were characterized and exhibited enhanced thermostability with approximately 5 °C higher in melting temperature (Tm), respectively, and a 45-fold longer half-life (t1/2) at 70 °C, compared to that of SpIFTase. Molecular dynamic simulations and elaborate structural analysis suggested that the combinations of hydrophobic interaction, electrostatic potential distribution, and decreased flexibility via stabilization of loops and α-helix improved the thermostability of SpIFTase. Additionally, the promising mutants exhibited great potential to the industrial production of DFA I.

Abstract
Difructose anhydride III (DFAIII) is a prebiotic involved in the reduction of secondary bile acids (BAs). We investigated whether DFAIII modulates BA metabolism, including enterohepatic circulation, in the rats fed with a diet supplemented with cholic acid (CA), one of the 12α-hydroxylated BAs. After acclimation, the rats were fed with a control diet or a diet supplemented with DFAIII. After 2 weeks, each group was further divided into two groups and was fed diet with or without CA supplementation at 0.5 g/kg diet. BA levels were analyzed in aortic and portal plasma, liver, intestinal content, and feces. As a result, DFAIII ingestion reduced the fecal deoxycholic acid level via the partial suppression of deconjugation and 7α-dehydroxylation of BAs following CA supplementation. These results suggest that DFAIII suppresses production of deoxycholic acid in conditions of high concentrations of 12α-hydroxylated BAs in enterohepatic circulation, such as obesity or excess energy intake. Abbreviation: BA: bile acid; BSH: bile salt hydrolase; CA: cholic acid; DCA: deoxycholic acid; DFAIII: difructose anhydride III; MCA: muricholic acid; MS: mass spectrometry; NCDs: non-communicable diseases; LC: liquid chromatography; SCFA: short-chain fatty acid; TCA: taurocholic acid; TCDCA: taurochenodeoxycholic acid; TDCA: taurodeoxycholic acid; TUDCA: tauroursodeoxychlic acid; TαMCA: tauro-α-muricholic acid; TβMCA: tauro-β-muricholic acid; TωMCA: tauro-ω-muricholic acid.
