An efficient, large-scale synthesis of piperazine-2,6-dione was developed. The advantages of this procedure include the use of inexpensive starting materials, satisfactory yields, and a convenient workup without the need for chromatographic techniques. Furthermore, this procedure can be easily modified for the preparation of 1-substituted piperazine-2,6-dione hydrobromides. The utility of the prepared piperazine-2,6-dione was demonstrated in the synthesis of a novel analogue of the only drug used in clinical practice to prevent anthracycline-induced cardiotoxicity, dexrazoxane.

Insulin degrading enzyme (IDE) is a zinc metalloprotease that degrades small amyloid peptides such as amyloid-a and insulin. So far the dearth of IDE-specific pharmacological inhibitors impacts the understanding of its role in the physiopathology of Alzheimer's disease, amyloid-a clearance, and its validation as a potential therapeutic target. Hit 1 was previously discovered by high-throughput screening. Here we describe the structure-activity study, that required the synthesis of 48 analogues. We found that while the carboxylic acid, the imidazole and the tertiary amine were critical for activity, the methyl ester was successfully optimized to an amide or a 1,2,4-oxadiazole. Along with improving their activity, compounds were optimized for solubility, lipophilicity and stability in plasma and microsomes. The docking or co-crystallization of some compounds at the exosite or the catalytic site of IDE provided the structural basis for IDE inhibition. The pharmacokinetic properties of best compounds 44 and 46 were measured in vivo. As a result, 44 (BDM43079) and its methyl ester precursor 48 (BDM43124) are useful chemical probes for the exploration of IDE's role.
BUPRENORPHINE DERIVATIVES AND USES THEREOF

, (2008/06/13)
Ester derivatives of the phenolic hydroxyl group of buprenorphine are described that can be used in the treatment of opiate dependency and/or moderate to severe pain. The esters have an enhanced bioavailability, an enhanced duration of action, and a reduc
