Secondary structures tend to be recognizable because they have repeating structural motifs, but mimicry of these does not have to follow such well‐defined patterns. Bioinformatics studies to match side‐chain orientations of a novel hydantoin triazole chemotype ( 1 ) to protein‐protein interfaces revealed it tends to align well across parallel and antiparallel sheets, like rungs on a ladder. One set of these overlays was observed for the protein‐protein interaction uPA?uPAR. Consequently, chemotype 1 was made with appropriate side‐chains to mimic uPA at this interface. Biophysical assays indicate these compounds did in fact bind uPAR, and elicit cellular responses that affected invasion, migration, and wound healing. 相似文献

The enthalpy of hydrolysis of solid tungsten thiotetrafluoride, WF(in4)S, in aqueous sodium hydroxide solution is -528.2 kJ mo1-1. Hence its standard enthalpy of formation has been calculated to be -1150.5 kJ mo1-1. 相似文献

Tidal forcing of the shallow water equations is typical of a class of problems where an approximate equilibrium solution is sought by long time integration of a differential equation system. A combination of the angled-derivative scheme with a staggered leap-frog scheme is sometimes used to discretise this problem. It is shown here why great care then needs to be taken with the boundary conditions to ensure that spurious solution modes do not lead to numerical instabilities. Various techniques are employed to analyse two simple model problems and display instabilities met in practical computations; these are then used to deduce a set of stable boundary conditions.Dedicated to Professor J.

Bound state population dynamics in a diatom modelled by an appropriate Morse oscillator with a time-dependent well-depth is
investigated perturbatively both in the absence and presence of high intensity radiation. For sinusoidally oscillating well-depth,
the population of themth bound vibrational level,P
mm(t), is predicted to be a parabolic function of the amplitude of the oscillation of the well-depth (ΔD
0) at a fixed laser intensity. For a fixed value of ΔD
0,P
mm(t) is also predicted to be quadratic function of the field intensity (ɛ
0). Accurate numerical calculations using a time-dependent Fourier grid Hamiltonian (TDFGH) method proposed earlier corroborate
the predictions of perturbation theory. As to the dissociation dynamics, the numerical results indicate that the intensity
threshold is slightly lowered if the well-depth oscillates. Possibility of the existence of pulse-shape effect on the dissociation
dynamics has also been investigated. 相似文献

Summary Solubilities of bis-(2,2-bipyridyl)- and bis-(1,10-phenanthroline)dicyanoiron(II) are reported for a range of primary aliphatic alcohols, from MeOH to 1-decanol. The established trends are compared with those for other solutes, and for the title compounds in H2O-alcohol solvent mixtures. 相似文献

Summary Different approaches to the interpretation of solvent effects on reactions between ionic reactants are analysed, taking as a basis the kinetic data corresponding to the sulphite-hexacyanoferrate(III) and peroxodisulphate-hexacyanoferrate(III) oxidations. It is concluded that the approach based on the use of solvent parameters is the more promising, although knowledge of the transfer chemical potentials of the reactants may also be useful in the interpretation of kinetic behaviour. 相似文献
