N-Glycine-sulfonamides as potent dual orexin 1/orexin 2 receptor antagonists
摘要:
A series of dual OX(1)R/OX(2)R orexin antagonists was prepared based on a N-glycine-sulfonamide core. SAR studies of a screening hit led to compounds with low nanomolar affinity for both receptors and good oral bioavailability. One of these compounds, 47, has demonstrated in vivo activity in rats following oral administration. (C) 2008 Elsevier Ltd. All rights reserved.

A straightforward multicomponent sulfonamidation of nitroarenes, sodium metabisulfite and boronic acids was established under transition‐metal‐free conditions to access diverse sulfonamides from readily available and low‐cost materials modularly. Inorganic salt sodium metabisulfite not only served as a sulfur dioxide source, but also played a key role for both activator and reductant during sulfonamidation
The invention relates to novel sulfonylamino-acetic acid derivatives and their use as active ingredients in the preparation of pharmaceutical compositions. The invention also concerns related aspects including processes for the preparation of such compounds, pharmaceutical compositions containing one or more of those compounds and especially their use as orexin receptor antagonists.

Structure-activity relationship studies of substituted arylsulfoanilides as antiproliferatives, which are mediated by the partial depletion of intracellular Ca2+ stores, resulted in the identification of compounds with micromolar activity against lung cancer cells in a growth inhibition assay. Incorporating the substitution pattern of the best arylsulfoanilides onto the 3-phenyloxindole scaffold resulted in a potent arylsulfoanilide-oxindole hybrid, 27. Compound 27 inhibits cancer cell growth by partial depletion of intracellular Ca2+ stores and phosphorylation of eIF2alpha.
