摘要: Various binding modes of 4,4鈥bipyridine N,N鈥dioxide (L) for crystal engineering are demonstrated in the complexes [Zn(MeOH)2L3](SiF6)路3MeOH and [ZnL6](NO3)2, which include examples of M鈥揕 coordination bonds, hydrogen-bonding and 蟺鈥撓stacking interactions....
4c). However, S3-15 was observed to generate induced-fit conformations that let S3-15 interacts with K180 and Q236 (mouse RANKL K180 and Q236 are equivalent to rat RANKL K182 and Q238) and form a H-bond between S3-15 and D303 (mouse RANKL D303 is equivalent to rat RANKL D305)...
(e.g.: CH3 and CH4, TMD1+TMD2, TM2ic, and TM3ic) was attenuated or rearranged relative to the WT (Fig.3b, cand Supplementary Fig.4), likely contributing to the F508G-CFTR impeded posttranslational conformational maturation and the destabilization of its complex-glycosylated fold (...

1. A compound having a substituted coumarylmethyl group connected to the nitrogen atom of the α-amino group of an L-threo-β-benzyloxylasparate or its benzene ring-substituted analog through a carbamate bond, represented by the following formula (2): wherein R1 represents hydrogen atom, amino...
It has been found that hitherto unknown derivatives of dihydro-pyridone can be obtained if strong acids, in presence or absence of a solvent, are caused to act on nitriles or amides of derivatives of
an extender B POS of the SiH type or an α,ω--(CH3)2 HSiO POS; a crosslinker C POS of the SiH (or even SiVi) type; and a hydrosilylation catalyst (Pt); with the condition that the number of hydrogen atoms linked to silicon represents more than 80% in number of the hydrogen...
Alternatives to lead must fulfill some very stringent criteria to match the current performance of lead-halide perovskites, namely: (1) any alternatives should be low-cost, using abundant elements, be eas- ily-recycled, and should form new compounds with a stable perovskite structure; (2) these...
