Definitions
- the invention relates to novel pharmaceutical compositions containing lipopeptides, to the use of such compositions, to processes for their preparation and to their use as medicaments.

- cyclodextrins in pharmaceutical compositions. Due to their circular structure, cyclodextrins have a hydrophilic outside and a hydrophobic inside pocket. By enveloping in particular hydrophobic regions of the molecules, cyclodextrins can achieve a "molecular encapsulation" or “masking" of active substances, which is used, for example, as a protective coating of sensitive molecules in cosmetic and pharmaceutical formulations. This allows improved solubilities of Substances, but also reduced toxicities, such as a reduction in the hemolytic properties of molecules (J. Pharmacobiodyn.

- SBE- / 3-CD was a molar ratio (SBE- / 3-CD: Friulimicin B) of 2.5: 1 before.
- the data for the Ca 2 Cl 2 -frulimicin B concentration (in mg / l) refer to the final concentrations of the free acid of friulimicin B in the reaction mixture.
- the details of the molar ratio relate in each case to the free acids of friulimicin B and SBE- ⁇ -CD.
- Ca 2 Cl 2 -friulimicin B serves as an example molecule for the antibiotics from the class of lipopeptides and sulfobutyl ether-J ⁇ -cyclodextrin (SBE-J ⁇ -CD) as examples of modified ⁇ -cyclodextrins.
- Ca 2 Cl 2 -frulimicin B was dissolved in 0.9% NaCl solution with and without the addition of SBE- / 3-CD.
- SBE-jß-CD was a molar ratio (SBE-jß-CD: Friulimicin B) of 2.5: 1 before.
- the data for the Ca 2 Cl 2 -frulimicin B concentration (in mg / l) refer to the final concentrations of the free acid of friulimicin B in the reaction mixture.
- the details of the molar ratio relate in each case to the free acids of friulimicin B and SBE- ⁇ -CD.
- the Ca 2 Cl 2 -frulimicin B solutions with and without SBE- / 3-CD were administered once to female mice (CFW-I (Harlan Winkelmann, Germany)) (iv).
- the mortality rate of the animals within 24 hours was determined. It is shown in Table 11.
- the example shows that the acute toxicity of Ca 2 Cl 2 -friulimicin B is reduced by the presence of SBE- ⁇ -CD in a molar ratio of 2.5: 1 (SBE- / 3-CD: friulimicin B).
