Investigations into self-association of vancomycin covalent dimers using surface plasmon resonance technology.
Covalent dimers of vancomycin linked through the vancosamine sugar moieties of the glycopeptide antibiotic have been synthesized in one step in 67-69% yield. The propensity for self-association of these and related vancomycin covalent dimers is evaluated using surface plasmon resonance technology.

8-acenaphthen-1-yl-1-phenyl-1,3,8-triaza-spiro[4.5]decan-4-one derivatives as orphanin FQ receptor agonists.
A series of 8-acenaphthen-1-yl-1-phenyl-1,3,8-triaza-spiro[4.5]decan+ ++-4-one derivatives 1 was studied with respect to the binding affinity for the orphanin FQ (OFQ) and opioid (mu, kappa, delta) receptors. The influence of stereochemistry as well as the substitution pattern of the phenyl-ring in position 1 on the affinity for the orphanin FQ receptor and selectivity to opioid (mu, kappa, delta) receptors is discussed. The most interesting compound 1c was tested for its anxiolytic-like properties in vivo.
