Influence of immunization with non-genotoxic PAH–KLH conjugates on the resistance of organisms exposed to benzo(a)pyrene
Autor: Šárka Klimešová, Luděk Lepša, Heda Černohorská, Alena Milcova, Jan Topinka, Jana Schmuczerova, Pavel Jinoch, Juraj Labaj
Publikováno v: Mutation Research/Genetic Toxicology and Environmental Mutagenesis. 742:2-10
Polycyclic aromatic hydrocarbons (PAH) are recognized as common environmental pollutants released into the environment from many natural as well as man-made sources, and some have been classified as potent carcinogens. The main representative of the

Chiral analysis of biogenicDL-amino acids derivatized by urethane - protected α-amino acidN-carboxyanhydride using capillary zone electrophoresis and micellar electrokinetic chromatography
Autor: Luděk Lepša, Martin Flegel, Ivan Jelínek, Martin Pumera
Publikováno v: ELECTROPHORESIS. 23:2449-2456
A new analytical method for enantioselective separation of DL-amino acids derivatized by N-fluorenylmethoxycarbonyl-L-alanyl N-carboxyanhydride (FMOC-L-Ala-NCA) using capillary electrophoresis was developed. Separation parameters, such as composition

Identification of the cockroach neuropeptide Pea-CAH-II as a second adipokinetic hormone in the firebug Pyrrhocoris apterus
Autor: Luděk Lepša, Dalibor Kodrík, Petr Šimek, Radomír Socha
Publikováno v: Peptides. 23:585-587
A new member of the AKH/RPCH family was isolated from the corpora cardiaca of the firebug Pyrrhocoris apterus. It is the second adipokinetic peptide identified in this species. The peptide was characterized and its structure was deduced from the mult

Acidic Cleavage of the Side Chain Protecting Groups of Peptides Attached to a Modified Polystyrene Carrier: Synthesis of Peptide Generics
Autor: Anna Ammerová, Luděk Lepša, Martin Flegel
Publikováno v: Peptides: The Wave of the Future ISBN: 9789401039055
High or good yield is essential for peptide production. The side chain protecting groups are cleaved usually in solution, after peptide detachment from the solid carrier. This can, however, be accompanied by the loss of material and the decrease in y

Homogeneous hydrogenation and deuteration of pentacyclic triterpenoids: Double bonds in side-chains
Autor: Jiří Klinot, Alois Vystrčil, Luděk Lepša, Jiří Protiva, Václav Křeček, Eva Klinotová
Publikováno v: Collection of Czechoslovak Chemical Communications. 46:2734-2741
The reduction of terminal double bonds in the side chains on the rings A and E of pentacyclic triterpenoids by means of tris(triphenylphosphine)rhodium chloride permits selective reduction of dienes and labelling with deuterium with a low scattering.
