The present invention relates to (2-aminoacylamino-2-deoxy-glycosyl)-amides, which are substituted on the nitrogen atom of the amino acid, of the general formula (I) ##STR1## in which the substituents have the meaning given in the description, to processes for their preparation and to their use in medicaments.

Glycosyl-amides of 2-aminoacylamino-2-deoxy-sugars

Glycosylamides of 2-aminoacylamino-2-deoxy sugars

A process for the preparation of glycoproteins and proteins from cultures of archaebacteria, comprising culturing archaebacteria, isolating glycoprotein and/or protein from the archaebacteria or their cell walls, enzymatically degrading the glycoprotein and/or protein, purifying and isolating the degradation products, and separating those fractions in the individual purification steps based on the biological activity of the fraction. The products increase the body's defenses against infection.

Preparation of immunologically active cell wall components from

The invention relates to new N-glycosylamides of the general formula I ##STR1## in which R.sup.1 denotes a saturated alkyl radical or a singly, doubly or triply unsaturated alkenyl radical having up to 50 carbon atoms,

Substituted N-glycosylamides, process for their preparation, and their

A method for decontaminating cell cultures comprising contacting cell cultures with quinolone- and 1,8-naphthyridonecarboxylic acids of the formula (I) ##STR1## in which R.sup.1 represents methyl, ethyl, propyl, isopropyl, cyclopropyl, vinyl, 2-hydroxyethyl, 2-fluorethyl, methoxy, amino, methylamino, dimethylamino, ethylamino, phenyl, 4-fluorophenyl or 2,4-difluorophenyl,

Method for decontamination of mycoplasma-infected cell cultures

A N-glycosylamide derivative of the formula (I) ##STR1## in which R.sup.1 denotes hydrogen or a saturated or mono- or polyunsaturated alkyl radical with one to 50 carbon atoms,

N-glycosylamide derivatives, processes for their preparation and their

Compounds of the formula ##STR1## in which R.sup.1 denotes hydrogen or a saturated or singly or multiply unsaturated alkyl radical having up to 50 carbon atoms,
