Šolínová, Veronika ; Kašička, Václav ; Koval, Dušan ; Hlaváček, Jan ; Barth, Tomislav
Capillary zone electrophoresis has been applied to the analysis, separation and physicochemical characterization of synthetic biopeptides such as insect oostatic peptides, enkephalins and dalargin.
Receptor-selective enkephalin analogs
Pencheva, N. ; Barth, Tomislav
We investigated the opioid profiles of [Cys2]-enkephalin (enk) analogs and [D-Ala2,Leu5]-enkephalyl-Arg (dalargin) in in vitro bioassay system. The results showed that incorporation of hydrophilic Cys(O2NH2)2 into the enk molecule greatly increases the potency and selectivity of the analogs to ë-opioid receptors, while substitution of D-Ala2 and Arg6 into the molecule of [Leu5]-enk, to ć-opioid receptors.
