Urinary metabolic fingerprinting of mice with diet-induced metabolic derangements by parallel dual secondary column-dual detection two-dimensional comprehensive gas chromatography.
J. Chromatogr. A. 1361 , 265-76, (2014) This study investigates the potential of a parallel dual secondary column-dual detection two-dimensional comprehensive GC platform (GC×2GC-MS/FID) for metabolic profiling and fingerprinting of mouse urine. Samples were obtained from a murine model that mimics... |

The identification of a novel SIRT6 modulator from Trigonella foenum-graecum using ligand fishing with protein coated magnetic beads.
J. Chromatogr. B. Analyt. Technol. Biomed. Life Sci. 968 , 105-11, (2014) SIRT6 is a histone deacetylase that has been proposed as a potential therapeutic target for metabolic disorders and the prevention of age-associated diseases. Thus the identification of compounds that modulate SIRT6 activity could be of great therapeutic impo... |

cIEF for rapid pKa determination of small molecules: a proof of concept.
Eur. J. Pharm. Sci. 63 , 14-21, (2014) A capillary isoelectric focusing (cIEF) method was developed for the determination of the ionization constants (pKa) of small molecules. Two approaches used to decrease the electroosmotic flow (EOF) were compared: (i) a hydroxypropylcellulose (HPC) coated cap... |

Highly charged cellulose-based nanocrystals as flocculants for harvesting Chlorella vulgaris.
Bioresour. Technol. 194 , 270-5, (2015) This study presents a novel flocculant for harvesting Chlorella vulgaris as model species for freshwater microalgae based on cellulose nanocrystals (CNCs), thus synthesized from a renewable and biodegradable resource. Cationic pyridinium groups were grafted o... |

Abiogenic Syntheses of Lipoamino Acids and Lipopeptides and their Prebiotic Significance.
Orig. Life Evol. Biosph. 45 , 427-37, (2015) Researchers have formed peptide bonds under a variety of presumed prebiotic conditions. Here it is proposed that these same conditions would have also formed amide bonds between fatty acids and amino acids, producing phosphate-free amphipathic lipoamino acids... |
