Featured researches published by Viktor Krchňák.

Cellular and Molecular Life Sciences | 1979

Structure specificity of some immunoadjuvant synthetic glycopeptides

K. Mašek; M. Zaoral; Jan Ježek; Viktor Krchňák

The immunoadjuvant activity of muramyl dipeptide seems to be critically dependent on the type of substitution of the γ-carboxyl group of the D-isoglutamine residue. Moreover the nonapeptide L-Ala-D-isoGlu-L-Lys-D-Ala-(Gly)5-OME also shows a definite effect.

International Journal of Peptide and Protein Research | 2009
