- COMPOSITIONS AND METHODS FOR SYNTHESIZING (2S,3S)-TRANS-EPOXYSUCCINYL-L-LEUCYL-AMIDO-3-METHYLBUTANE ETHYL ESTER
-
In alternative embodiments the invention provides methods for synthesizing AB-007 (also called loxistatin, E64d, EST or ((2S,3S)-trans-epoxysuccinyl-L-leucyl-amido-3-methylbutane ethyl ester) and its acid form E64c (loxistatin acid), and various synthetic

- Design, synthesis, and screen of cathepsin K inhibitors
-
We synthesized a series of epoxysuccinic acid derivatives and evaluated their in vitro cathepsin K inhibitory activity The screening results show that the potency of compounds 9e, 9d, 9p, 9j and 9k (IC50 ≤ 0.005 μmol/L) were equal to or greater than that of the lead compound 9a. Less hydrophobic compounds showed weaker potency, which can be explained by the hydrophobic nature of the cathepsin K binding pockets.

- A new synthesis of peptidyl epoxysuccinates for probing cysteine protease-inhibitor P3/S3 binding interactions
-
A new synthesis of peptidyl epoxysuccinates has been developed involving the N-acylation of amino acid benzyl esters (12) with the tartrate ester derived epoxy acid 13 followed by deprotection of the benzyl esters and acylation with amines 21-28. This syn
