Summary Protein–protein interactions are ubiquitous, essential to almost all known biological processes, and offer attractive opportunities for therapeutic intervention. Developing small molecules that modulate protein–protein interactions is challenging, owing to the large size of protein-complex interface, the lack of well-defined binding pockets, etc. We describe a general approach based on the “privileged-structure hypothesis” [Che, Ph.D. Thesis, Washington University, 2003] – that any organic templates capable of mimicking surfaces of protein-recognition motifs are potential privileged scaffolds as protein-complex antagonists – to address the challenges inherent in the discovery of small-molecule inhibitors of protein–protein interactions.This paper is adapted from a presentation at the 230th National Meeting of the American Chemical Society, Washington DC, August 28 – September 1, 2005, Abstract COMP-136. 相似文献

The donor-functionalised alkoxides {Me(3-x)N(CH(2)CH(2)O)(x)} (L(x); x = 1, 2) have been used to form gallium hydride complexes [{GaH(2)(L(1))}(2)] and [{GaH(L(2))}(2)] that are stable and isolable at room temperature. Along with a heteroleptic gallium tris(alkoxide) complex [Ga(L(1))(3)] and the dimeric complex [{GaMe(L(2))}(2)], these compounds have been used as single-source precursors for the deposition of Ga(2)O(3) by aerosol-assisted chemical vapour deposition (AACVD) with toluene as solvent. The resulting films were mostly transparent, indicating low levels of carbon contamination, and they were also mainly amorphous. However, [Ga(L(1))(3)] did contain visibly crystalline material deposited at a substrate temperature of 450?°C, by far the lowest ever observed for the CVD of gallium oxide. 相似文献

Two new complexes of the Ln2(oda)3·nH2O (oda =–O2CCH2OCH2CO2–) series are reported, i.e. {[Pr2(C4H4O5)3(H2O)3]·5H2O}n and {[Nd2(C4H4O5)3(H2O)6]·C4H6O5·‐2H2O}n. The former is isostructural with the reported La analogue, while the latter is a new structural variety within the series. Each compound exhibits two independent nine‐coordinated Ln centres showing a variety of coordination geometries. 相似文献

We have studied by electrolyte electroreflectance and photoluminescence a GaAs/AlGaAs resonant tunneling structure (RTS) with a highly n-doped GaAs cap, before and after hydrogenation. We measured the amount of passivation of shallow donor states and of deep traps in the cap and found the approximate pinning levels and interace charges of the RTS. 相似文献

Effect of Si in reactively sputtered Ti-Si-N films on structure and diffusion barrier performance 总被引:2,自引:0,他引:2

34 Si23N43 (b3) and Ti35Si13N52 (c3), are synthesized by reactively sputtering a Ti5Si3 or a Ti3Si target, respectively. The silicon-lean film (c3) has a columnar structure closely resembling that of TiN. As a diffusion
barrier between a shallow Si n+p junction diode and a Cu overlayer, this material is effective up to 700 °C for 30 min annealing in vacuum, a performance
similar to that for TiN. The silicon-rich (b3) film contains nanocrystals of TiN, randomly oriented and embedded in an amorphous
matrix. A film of (b3) maintains the stability of the same diode structure up to 850 °C for 30 min in vacuum. This film (b3)
is clearly superior to TiN or to (c3). Similar experiments performed with Al instead of Cu overlayers highlight the importance
of the thermodynamic stability of a barrier layer and demonstrate convincingly that for stable barriers the microstructure
is a parameter that directly determines the barrier performance.

An a.c. calorimetric technique has been used to measure the heat capacity variation associated with the smectic A—smectic C transition in terephthal-bis-(4n)-butylaniline (TBBA). Contrary to expectations based on the recent observation of petransitional acoustic effects in the semectic-A phase, the heat capacity shows no evidence of critical fluctuations and can be well described by a Landau mean-field model. 相似文献
