The pyrokinin/pheromone biosynthesis activating neuropeptide (PK/PBAN) family plays a significant role in a multifunctional array of important physiological processes in insects. PK/PBAN analogs incorporating beta-amino acids were synthesized and evaluated in a pheromonotropic assay in Heliothis peltigera, a melanotropic assay in Spodoptera littoralis, a(More)
The multifunctional arthropod 'insect kinins' share the evolutionarily conserved C-terminal pentapeptide motif Phe-X1-X2-Trp-Gly-NH2, where X1=His, Asn, Ser, or Tyr and X2=Ser, Pro, or Ala. Eight different analogs of the insect kinin C-terminal pentapeptide active core in which the critical residues Phe 1, Pro3 and Trp 4 are replaced with beta 3-amino acid(More)
Quorum-sensing (QS) is a bacterial mechanism for regulation of gene expression in response to cell density. In Gram-positive bacteria, oligopeptides are the signaling molecules to elicit QS. The RNPP protein family (Rap, NprR, PlcR, and PrgX) are intracellular QS receptors that bind directly to their specific signaling peptide for regulating the(More)
Enantiomerically enriched hydroxy-substituted beta-amino esters have been synthesized through CAL-B-catalyzed enantioselective hydrolysis in organic media. Moderate to good enantiomeric excess values (ee > or = 52%) were obtained when the CAL-B-catalyzed reactions were performed in t-BuOMe, at 60 degrees C with 0.5 equiv. of added H(2)O as nucleophile.

Editorial Last year, we have seen the passing of one of the most influential researchers in the field of Stereochemistry, Professor Ernest L. Eliel, who played a key role in the development of this area in the world. Dr. Eliel is recognized by his seminal and numerous scientific contributions, by his service to chemistry through the activities of the(More)
