Further modification on phenyl acetic acid based quinolines as liver X receptor modulators
摘要:
A series of phenyl acetic acid based quinolines was prepared as LXR modulators. An SAR study in which the C-3 and C-8 positions of the quinoline core were varied led to the identification of two potent LXR agonists 23 and 27. Both compounds displayed good binding affinity for LXR beta and LXR alpha, and increased expression of ABCAl in THP-1 cells. These two compounds also had desirable pharmacokinetic profiles in mice and displayed in vivo efficacy in a 12-week Apo E knockout mouse lesion model. (c) 2007 Elsevier Ltd. All rights reserved.

The present disclosure provides a class of compounds useful for the modulation of beta-secretase enzyme (BACE) activity. The compounds have a general Formula I: wherein variables A, X, R2, R2', R3, R4, R5, R6, and R7 of Formula I are defined herein. This disclosure also provides pharmaceutical compositions comprising the compounds, and uses of the compounds and compositions for treatment of disorders and/or conditions related to Aβ plaque formation and deposition, resulting from the biological activity of BACE. Such BACE mediated disorders include, for example, Alzheimer's Disease, cognitive deficits, cognitive impairments, and other central nervous system conditions.

difluorides to generate axiallychiral, tetrasubstituted monofluoroallenes in both good yields (27 examples >80%) and enantioselectivities (82–98% ee). Compared to previously reported synthetic routes to axiallychiralallenes (ACAs) from prochiral substrates, a mechanistically distinct reaction has been developed: the enantiodiscrimination between enantiotopic fluorides to set an axial stereocenter.

A palladium-catalyzed Negishi cross-coupling reaction of ethyl bromodifluoroacetate with arylbromides or aryl triflates to construct C(sp2)–CF2 bonds is described. The reaction was conducted under mild reaction conditions, and no preparation of organozinc reagents is required. This is the first report encompassing the conversion of aryl triflates into products containing C–CF2 bonds. In addition,
