Cyclopentane-based human NK1 antagonists. Part 2: Development of potent, orally active, water-soluble derivatives
摘要:
The synthesis and optimization of a cyclopentane-based hNK1 antagonist scaffold 3, having four chiral centers, will be discussed in the context of its enhanced water-solubility properties relative to the marketed anti-emetic hNK1 antagonist EMEND (R) (Aprepitant). Sub-nanomolar hNK1 binding was achieved and oral activity comparable to Aprepitant in two in vivo models will be described. (c) 2006 Elsevier Ltd. All rights reserved.
The present invention is directed to certain hydroisoindoline compounds which are useful as neurokinin-1 (NK-1) receptor antagonists, and inhibitors of tachykinin and in particular substance P. The invention is also concerned with pharmaceutical formulations comprising these compounds as active ingredients and the use of the compounds and their formulations in the treatment of certain disorders, including emesis, urinary incontinence, depression, and anxiety.

An asymmetric total synthesis of Merck’s hNK1 antagonist and three of itsstereoisomers was accomplished in 10 steps. The synthesis involves a stereoselective assembly of 1,2-oxazine N-oxide by the [4 + 2]-cycloaddition, site-selective C–H oxygenation using a novel tandem acylation/[3,3]-rearrangement process and the reductive 1,2-oxazine ring contraction into a pyrrolidine ring as key stages.
