Cbz) 4-(1,2,3-triazol-4-yl)-substituted 3-aminopiperidines are new scaffolds for combinatorial chemistry. They were prepared from a piperidine building block by a sequence of nucleophilic aziridine ring opening with NaN 3 and subsequent copper-catalyzed Huisgen 1,3-dipolar cycloaddition with ten different alkynes. Constitution and relative configuration of the major as well as minor products were established

Diaminoalkanes of Formula I have now been found which are orally active and bind to aspartic proteases to inhibit their activity. They are useful in the treatment or amelioration of diseases associated with elevated levels of aspartic protease activity. The invention also relates to a method for the use of the compounds of Formula I in ameliorating or treating aspartic protease related disorders in a subject in need thereof comprising administering to said subject an effective amount of a compound of Formula I.
The present invention is directed to aspartic protease inhibitors. Certain aspartic protease inhibitors of the invention can be represented by the following structural formula or a pharmaceutically acceptable salt thereof. The present invention is also directed to pharmaceutical compositions comprising the disclosed aspartic protease inhibitors. The present invention is further directed to methods of antagonizing one or more aspartic proteases in a subject in need thereof, and methods for treating an aspartic protease mediated disorder in a subject using the disclosed aspartic protease inhibitors.
