Compounds having the formula (I) pharmaceutical compositions containing them and their methods of use for the treatment of neurological disorders related to amyloid ß protein production and neurological disorders such as Alzheimer's disease.. These compounds inhibit γ secretase and thereby inhibit the production of amyloid ß protein, thereby acting to prevent the formation of neurological deposits of amyloid protein.

Amidation of unprotected aminoacids has been investigated using a variety of ‘classical“ coupling reagents, stoichiometric or catalytic group(IV) metal salts, and boron Lewis acids. The scope of the reaction was explored through the attempted synthesis of amides derived from twenty natural, and several unnatural, aminoacids, as well as a wide selection of primary and secondary amines. The study also
The synthesis of trifluoromethyl (Tfm) analogs of known nanomolar matrix metalloproteinases (MMPs) inhibitors has been performed. The synthetic protocol is based on a moderately stereoselective aldol reaction of trifluoropyruvate with an N-acyl-oxazolidin-2-thione for the construction of the core α-Tfm-malic unit. Both the diastereomeric forms of the target α-Tfm-malic hydroxamates showed micromolar

(EN) Disclosed are novel inhibitors of collagenase-1 and stromelysin-I metalloproteases. The disclosed inhibitors are mercaptoketone and mercaptoalcohol compounds which are useful in pharmaceutical compositions and methods for treating or controlling disease states or conditions which involve tissue breakdown, for example, arthropathy, dermatological conditions, bone resorption, inflammatory diseases, and tumor invasion and in the promotion of wound healing.(FR) L'invention concerne de nouveaux inhibiteurs des métalloprotéases de collagénase-1 et de stromélysine-I. Ces inhibiteurs sont des composés de mercaptocétone et de mercapto-alcool utiles dans des compositions pharmaceutiques et dans des procédés pour traiter ou enrayer des états pathologiques qui impliquent la dégradation des tissus, par exemple l'arthropathie, les troubles dermatologiques, la résorption osseuse, les maladies inflammatoires et l'invasion par des tumeurs, ainsi que pour promouvoir la cicatrisation.
