摘要:
The invention relates to tumour therapy. In one aspect, the present invention relates to conjugates of a toxin and a target-binding moiety, e.g. an antibody, which are useful in the treatment of cancer. In particular, the toxin is an amatoxin, and the target-binding moiety is preferably directed against tumour-associated antigens. In particular, the amatoxin is conjugated to the antibody by linker moieties. In particular the linker moieties are covalently bound to functional groups located in positions of the amatoxin proved as preferred positions for the attachment of linkers with respect to optimum antitumor activity. In a further aspect the invention relates to pharmaceutical compositions comprising such target-binding moiety toxin conjugates and to the use of such target-binding moiety toxin conjugates for the preparation of such pharmaceutical compositions. The target-binding moiety toxin conjugates and pharmaceutical compositions of the invention are useful for the treatment of cancer.

摘要:
Astaxanthin derivatives of the general formula (I) wherein R is in each case group —NH—CH(R1)—COOR2, —OR3 or —(Y)n-Z and R1, R2, R3, Y, Z and n are significances given in detail in the description, are novel compounds with improved stability during extrusion at the elevated temperatures as required in feed manufacture and during the storage of the manufactured feed and which accordingly are useful as pigmenting carotinoids for feed for aquatic animals. The derivatives are produced by reacting astaxanthin with the pertinent acid RCOOH as such or as its acid chloride RCOC1 or acid anhydride (RCO)2O, or, in the cases where R signifies a group —NH—CH(R1)—COOR2, with the appropriate N-carbonyl-amino acid ester of the formula OCNCH(R1)COOR2. The invention also concerns a formulation containing such an astaxanthin derivative as the pigmenting carotenoid for use in a feed for aquatic animals, a process for producing such a formulation by dissolving the astaxanthin derivative in a plant or vegetable oil or fat, or in an organic solvent, or in a mixture of both a plant or vegetable oil or fat and an organic solvent, emulsifying the solution with an aqueous solution of a protective colloid, at least partially removing the solvent and water to afford a concentrated emulsion, and spray-drying the concentrated emulsion to finally produce a formulation suitable for incorporation in a feed for aquatic animals, and a feed for aquatic animals containing such a pigmenting carotenoid.
摘要:
A process for catalytically isomerizing Z-3-methylpent-2-en-4-yn-1-ol to E-3-methylpent-2-en-4-yn-1-ol is provided. This process includes contacting a stereoisomeric mixture containing Z-3-methylpent-2-en-4-yn-1-ol and E-3-methylpent-2-en-4-yn-1-ol with a source of bromine radicals in a two-phase reaction mixture having an aqueous phase and a stereoisomeric mixture phase, intermixing the reaction mixture, and heating the reaction mixture to a temperature from about −10° C. to about 100° C.
摘要:
The invention relates to a filter for brewed beverages, especially a coffee filter, and a process for producing such a filter, in which a fibrous material has pores with an average pore width (d) of at least about 0.1 mm measured at a fiber density of about 50% of the original fiber density of the material. The average pore width (d) is preferably in a range from 0.1 mm to 0.7 mm approximately and more preferably in a range from 0.1 mm to 0.4 mm approximately. The material is preferably paper. The pores are also preferably made by piercing with needles or by subjecting the fibrous material to water jets, providing an irregular pore edge.
