Chemical communicationsStructural isomers of m(dca)2 molecule-based magnets. Crystal structure of tetrahedrally coordinated sheet-like b-Zn(dca)2 and b-Co/Zn(dca)2, and the octahedrally coordinated rutile-like a-Co(dca)2, where dca-=dicyanamide, N(CN)2-,and magnetism of b-Co(dc. Jensen...
Amphipathic arginine-rich peptide, A2-17, exhibits moderate perturbation of lipid membranes and the highest cell penetration among its structural isomers. We investigated the direct cell-membrane penetration mechanism of the A2-17 peptide while focusing on structural flexibility. We designed conformationally...
2g, h). The same measurements were taken without Nb2 as controls for these experiments (Supplementary Fig. 4). Surprisingly, Nb2 was observed to shift the equilibrium of the photointermediates towards the Meta I-like species (Fig. 2e), thereby slowing the overall decay of bRho* to apo-...
The influence of heat on the oils resulted in a degradation of carotenoids and vitamin E isomers, correlating with an augmentation of oxidized components in both oil types. Experiments demonstrated that up to 150°C, both oil types can be used safely for cooking/frying, preserving their valuable...
aromatic ring and the piperidine basic nitrogen of these two isomers largely overlap in site BIG. The primary difference in the binding poses of the isomers is the opposite orientations of the butyl tail (Supplementary Fig.6). Therefore, both racemic isomers of BPV can be recognized at site ...
This molecule exhibited a good dose-dependent inhibitory effect against topoisomerase I with IC50 values at 7.25 ± 0.20 μg/ml, as compared to the positive control (camptothecin) at 6.72 ± 0.23 μg/ml (Chen et al. 2016). A few numbers of narciclasine-type ...
S5 are presented these same comparisons but in the 2000–0 cm−1 region. These two comparisons clearly evidence the presence of more than one molecule in the solid state due to the increase in the numbers and intensities of the bands in both spectra for this species in relation to the ...
These variants were subsequently labeled with IAEDANS, and FRET was measured between the lone intrinsic tryptophan in MBP (W113), which served as a donor, and the incorporated IAEDANS molecule, which served as an acceptor. Data were collected in 0%, 10%, 15%, and 30% TFE (v/v) in ...
(d,p) calculations were undertaken in order to explore the conformational space of both theE- andZ- geometrical isomers of the enol-imine and keto-amine tautomers of the compound. Optimized geometries and relative energies were obtained, and it was shown that the most stable species is theE-...
Figure 1. (a) The two conformation isomers (left: folded isomer; right: extended isomer) observed in GSH. The extended isomer was confirmed to be the most stable by DFT calculations. (b) Left: the optimized molecular structure of a GSH monomer. Right: the formed dimer as estimated from ...
