Efficient synthesis of cystine, selenocystine, and their higher homologues like homo and bishomo amino acid derivatives from natural amino acid derivatives using tetrathiomolybdate and tetraselenotungstate reagents under mild and neutral conditions is reported. The generality of the reaction has been studied by capping various groups to amino and carboxyl components of canonical amino acids.
Synthesis of new 3- and 4-substituted analogues of acyl homoserine lactone quorum sensing autoinducers

The quorum sensing mechanism in Gram-negative bacteria uses small intercellular signal molecules, N-acyl-homoserine lactones (AHLs), to control transcription of specific genes in relation to population density. In this communication, we describe the parallel synthesis of new AHL analogues, in which substituents have been introduced into the 3- and 4-positions of the lactone ring. These analogues have been screened for their ability to activate and inhibit a Vibrio fischeri LuxI/LuxR-derived quorum sensing reporter system.
α-Amino-β-sulphone hydroxamates as potent MMP-13 inhibitors that spare MMP-1
Becker, Daniel P,Barta, Thomas E,Bedell, Louis,DeCrescenzo, Gary,Freskos, John,Getman, Daniel P,Hockerman, Susan L,Li, Madeleine,Mehta, Pramod,Mischke, Brent,Munie, Grace E,Swearingen, Craig,Villamil, Clara I

A series of α-amino-β-sulphone hydroxamates was prepared and evaluated for potency versus MMP-13 and selectivity versus MMP-1. Various substituents were employed on the α-amino group (P1 position), as well as different groups attached to the su
