Enzymatic characterization and molecular modeling of an evolutionarily interesting fungal beta-N-acetylhexosaminidase

Fungal beta-N-acetylhexosaminidases are inducible extracellular enzymes with many biotechnological applications. The enzyme from Penicillium oxalicum has unique enzymatic properties despite its close evolutionary relationship with other fungal hexosaminidases. It has high GalNAcase activity, tolerates substrates with the modified N-acyl group better and has some other unusual catalytic properties. In order to understand these features, we performed isolation, biochemical and enzymological characterization, molecular cloning and molecular modelling. The native enzyme is composed of two catalytic units (65 kDa each) and two propeptides (15 kDa each), yielding a molecular weight of 160 kDa. Enzyme deglycosylated by endoglycosidase H had comparable activity, but reduced stability. We have cloned and sequenced the gene coding for the entire hexosaminidase from P. oxalicum. Sufficient sequence identity of this hexosaminidase with the structurally solved enzymes from bacteria and humans with complete conservation of all catalytic residues allowed us to construct a molecular model of the enzyme. Results from molecular dynamics simulations and substrate docking supported the experimental kinetic and substrate specificity data and provided a molecular explanation for why the hexosaminidase from P. oxalicum is unique among the family of fungal hexosaminidases.

Extra Sugar on Vancomycin: New Analogues for Combating Multidrug-Resistant Staphylococcus aureus and Vancomycin-Resistant Enterococci

Lipophilic substitution on vancomycin is an effective strategy for the development of novel vancomycin analogues against drug-resistant bacteria by enhancing bacterial cell wall interactions. However, hydrophobic structures usually lead to long elimination half-life and accumulative toxicity; therefore, hydrophilic fragments were also introduced to the lipo-vancomycin to regulate their pharmacokinetic/pharmacodynamic properties. Here, we synthesized a series of new vancomycin analogues carrying various sugar moieties on the seventh-amino acid phenyl ring and lipophilic substitutions on vancosamine with extensive structure-activity relationship analysis. The optimal analogues indicated 128-1024-fold higher activity against methicillin-susceptible S. aureus, vancomycin-intermediate resistant S. aureus (VISA), and vancomycin-resistant Enterococci (VRE) compared with that of vancomycin. In vivo pharmacokinetics studies demonstrated the effective regulation of extra sugar motifs, which shortened the half-life and addressed concerns of accumulative toxicity of lipo-vancomycin. This work presents an effective strategy for lipo-vancomycin derivative design by introducing extra sugars, which leads to better antibiotic-like properties of enhanced efficacy, optimal pharmacokinetics, and lower toxicity.

A Combined Chemical and Enzymatic Strategy for the Construction of Carbohydrate-Containing Antigen Core Units

Glycosidase-mediated coupling of glycal acceptors with galactose donors affords beta-1,3-linked dissacharides that are versatile intermediates for further chemical and enzymatic manipulation.The utility of these disaccharides is demonstrated by the elaboration of these compounds into type I and type IV core disaccharides of carbohydrate-containing antigens.Further conversion of the type IV dissacharide to a mucin-type trisaccharide (Galbeta1,3(GlcNAcbeta1,6)GalNAc) was accomplished with the use of a beta-1,6-N-acetylglucosaminyltransferase.This combined use of enzymatic andchemical methodologies allows for the rapid assembly, with high regio- and stereoselectivity, of core oligosaccharides of biologically important glycoconjugates.

TBAF Effects 3,6-Anhydro Formation from 6-O-Tosyl Pyranosides

3,6-Anhydro sugars are common structures in algal polysaccharides and occur in the furanodictine and sauropunol natural products. We have found that treatment of 6-O-tosylpyranosides with tetrabutylammonium fluoride provides a mild, high-yielding synthesis of 3,6-anhydro sugars. Using O-glycoside substrates, 3,6-anhydropyranosides are isolated and the use of N,O-dimethyl hydroxylamine glycosides yields 3,6-anhydrofuranosides. Applying this approach, concise synthetic routes to several 3,6-anhydro sugar natural products are reported, including furanodictine A and sauropunols A-D.

Synthesis and Selective Cyclooxygenase-2 Inhibitory Activity of a Series of Novel, Nitric Oxide Donor-Containing Pyrazoles

The synthesis of a series of novel pyrazoles containing a nitrate (ONO 2) moiety as a nitric oxide (NO)-donor functionality is reported. Their COX-1 and COX-2 inhibitory activities in human whole blood are profiled. Our data demonstrate that pyrazole ring substituents play an important role in COX-2 selective inhibition, such that a cycloalkyl pyrazole (6b) was found to be a potent and selective COX-2 inhibitor. Other modifications at the 3 position of the central pyrazole ring (17b, 23b, 26b-I) enhanced COX-2 inhibitory potency. Among the pyrazoles synthesized, the oxime (23b) was identified as the most potent COX-2 selective inhibitor. Accordingly, 23b was profiled pharmacologically in the rat after oral administration and shown to possess potent antiinflammatory activity in the carrageenan-induced air-pouch model and less gastric toxicity than a standard COX-2 inhibitor when administered with background aspirin treatment. We suggest that the enhanced gastric tolerance of an NO-donor COX-2 selective inhibitor has the potential to augment the clinical profile of this drug class.
