The preparation of the polyketide natural products anguinomycin C and D is reported based on key steps such as Negishi stereoinversion cross coupling, Jacobsen Cr(III)-catalyzed Hetero Diels−Alder reaction, Evans B-mediated syn-aldol chemistry, and B-alkyl ...
This paper employs a small open economy DSGE model, estimated over 1986-2009, to decompose the dynamic influence of domestic and international prices on the Canada-US real exchange rate. While the real exchange rate mimics the dynamic behavior of the relat ...
Ghent University Faculty of Economics and Business Administration Working Paper 2010/6552011
The conformations of a number of M2TMP-(22-46) sequence variants have been investigated using ion mobility spectrometry (IMS). Substantial conformational changes were evidenced by IMS upon the variation of a single amino acid in the peptide sequence, with ...
We report the total synthesis of a series of pyrrolizidine analogues of casuarine (1) and their 6-O-alpha-glucoside derivatives. The synthetic strategy is based on a totally regio- and stereoselective 1,3-dipolar cycloaddition of suitably substituted alken ...
The amyloid cascade hypothesis, supported by strong evidence from genetics, pathology and studies using animal models, implicates amyloid-beta (Abeta) oligomerization and fibrillogenesis as central causative events in the pathogenesis of Alzheimer's diseas ...
Epithelial cell migration requires coordination of two actin modules at the leading edge: one in the lamellipodium and one in the lamella. How the two modules connect mechanistically to regulate directed edge motion is not understood. Using live-cell imagi ...
The centriole, and the related basal body, is an ancient organelle characterized by a universal 9-fold radial symmetry and is critical for generating cilia, flagella, and centrosomes. The mechanisms directing centriole formation are incompletely understood ...
The Bingel addn. of a trimalonate derived from a chiral, cyclotriveratrylene (CTV)-based tripodal tether to C60 was reinvestigated. The present use of enantiomerically pure (P)- and (M)-configured CTV units in the tether allowed the isolation of a total of ...
Measurements of proton-driven carbon-13 spin diffusion (PDSD) by NMR spectroscopy are a central component of structural analyses of biomolecules in the solid-state. However, the quantitative link between experimental PDSD data and structural information is ...
Members of the human APOBEC3 family of editing enzymes can inhibit various mobile genetic elements. APOBEC3A (A3A) can block the retrotransposon LINE-1 and the parvovirus adeno-associated virus type 2 (AAV-2) but does not inhibit retroviruses. In contrast, ...
