Abstract:
The present invention is directed towards new 18F-folate radiopharmaceuticals, wherein fluorine-18 is covalently linked through a triazole- or tetrazole linker to a folate or derivative thereof, a method of their preparation, as well as their use in diagnosis and monitoring of therapy of cancer and inflammatory and autoimmune diseases.
Abstract:
An optical assembly, which is in particular in the form of a splitter component with a so-called splitter forming a passive optical component, is produced particularly inexpensively. In a first step a plurality of splitters are produced on a common wafer by forming a corresponding conductor track pattern. In a second step optical fibers are coupled simultaneously to the connection sides of the individual splitters with the aid of a connection carrier. Then, in a third step the individual splitters with the connection carriers connected thereto are separated form one another. Only one common coupling operation for a large number of splitters is required. The splitters may then be connected to form a splitter cascade.
Abstract:
The present invention is directed towards new 18F-folate radio-pharmaceuticals, wherein the fluorine-18 is covalently linked to the aminobenzoyl moiety, which connects the condensed pyrimidine heterocycle to the amino acid portion within folate structures, as well as their precursors and their non-radioactive references, a method of their preparation, as well as their use in diagnosis of a cell or population of cells expressing a folate-receptor and monitoring of cancer and inflammatory and autoimmune diseases and therapy thereof.
