摘要:
A method for the manufacture of compounds containing an α-oxy phosphorus group is disclosed. A P-O component having at least one P-O-P moiety, whereby at least one phosphorus has the +3 oxidation state, is added in specific proportions to a compound containing an α-oxy carboxylic acid group, followed by conducting the reaction and adding water subsequently. The compounds containing an α-oxy phosphorus group formed can then be recovered.

摘要:
Amphiphilic derivatives composed of at least one fatty acid chain are derived from natural vegetable oils such as vernonia oil, lesquerella oil and castor oil, in which the several reactive groups such as epoxy, hydroxy and double bonds can be modified to polar and ionic groups. The head group of the amphiphilic derivative may be in the main fatty acid chain or in a side chain. The amphiphiles are useful for the formation of vesicles and micelles and for use as complexants and surfactants.

摘要:
The invention relates to novel biologically active compounds of fungi of the species Ganoderma pfeifferi DMS 13239, to methods of preparing same and to their use. From the fruit-body and mycelium of Ganoderma pfeifferi DMS 13239 extracts having an antimicrobial action and suitable as preservatives, for pharmaceutical and cosmetic preparations, as antiinfective agents and in fish-farming can be obtained. Antimicrobial active substances called ganomycines which are effective against multi-resistant germs are isolated from the extracts. The total synthesis of the ganomycines and their derivatization permits their use as antibiotics.
