J Comb Chem
. 2000 Oct;
2(5):496-507.
PMID: 11029175
A method for solid-phase peptide synthesis in the N- to C-direction that delivers good coupling yields and a low degree of epimerization is reported. The optimized method involves the coupling,...

PMID: 11026551
Rigidification of peptides by cyclization and iterative incorporation of well-defined secondary structure mimetics constitutes one approach to the design of non-peptidergic structures with better defined conformations. We herein present the...

PMID: 10930266
The anabasine analogues spiro[4-azaindan-1,2'-piperidine] (7) and spiro[6-azaindan-1,2'-piperidine] (8) have been prepared. A series of palladium-catalyzed reactions, where an intramolecular cyclization constituted a key reaction, were utilized for the preparation of...

PMID: 10793244
First weeks after alcohol withdrawal, associated with profound changes in neural transmission, constitute the critical period for relapse prevention and pharmacological intervention in alcoholism. Here, 20 male alcoholics with 1-6...

PMID: 10579816
A simple experimental procedure on solid phase for the construction of new tripeptidic 5,9- and 5,10-fused thiazabicycloalkane scaffolds that adopt beta-turns has been developed. This N-terminal-directed bicyclization, relying on masked...
