摘要:
A compound of Formula (I), a pharmaceutically acceptable salt, or solvate thereof, complexes with metals such as rhenium, technetium, and others to provide a complex for imaging tissues or treating disease, particularly where the metal is radioactive. Such complexes are specific to PSMA protein and can therefore be used in imaging or treating cancer of the prostate and other tissue where the protein is expressed.

The invention provides methods for labeling vitamin B 12 with 14 C, 13 C tritium, and deuterium. When radioisotopes are used, the invention provides for methods of labeling B 12 with high specific activity. The invention also provides labeled vitamin B 12 compositions made in accordance with the invention.
摘要:
The invention relates to cobalamin derivatives (a) having no binding affinity or low binding affinity to the transport protein transcobalamin II TCII) and (b) retaining activity as a vitamin B12 substitute, optionally carrying a therapeutic and/or diagnostic agent, such as a radioactive metal. These compounds have a much reduced accumulation rate in blood and benign organs, such as kidney and liver, compared to the accumulation rate in neoplastic tissues, and are more rapidly eliminated from blood. The invention further relates to a method of diagnosis and a method of treatment of a neoplastic disease or an infection by microorganisms in a mammal comprising (a) exposing the mammal to a period of a vitamin B12 - free diet, and (b) subsequently applying a cobalamin derivative of the invention carrying a diagnostic and/or therapeutic agent. By selecting cobalamin derivatives acting as vitamin B12 substitutes, the risk of the formation of resistant offspring in neoplastic tissue is much reduced.
摘要:
The present invention relates to systems, compositions, and methods for the synthesis and use of imaging agents, or precursors thereof. An imaging agent precursor may be converted to an imaging agent using the methods described herein. In some cases, the imaging agent is enriched in 18 F. In some cases, an imaging agent may be used to image an area of interest in a subject, including, but not limited to, the heart, cardiovascular system, cardiac vessels, brain, and other organs. In some embodiments, methods and compositions for assessing perfusion and innervation mismatch in a portion of a subject are provided.
摘要:
The present invention relates to novel heteroaryl substituted imidazopyridine derivatives, precursors thereof, and therapeutic uses of such compounds, having the structural formula (Ia) and to their pharmaceutically acceptable salt, compositions and methods of use. Furthermore, the invention relates to novel heteroaryl substituted imidazopyridine derivatives that are suitable for imaging amyloid deposits in living patients, their compositions, methods of use and processes to make such compounds. More specifically, the present invention relates to a method of imaging amyloid deposits in brain in vivo to allow antemortem diagnosis of Alzheimer's disease as well as measureing clinical efficacy of Alzheimer's disease therapeutic agents.

摘要:
The present disclosure is directed to modulators of opiate- and/or NMDA receptors and pharmaceutically acceptable salts and prodrugs thereof, the chemical synthesis thereof, and the use of such compounds for the treatment and/or management of pain, anxiety, neurodegeneration, drug dependence, coughing, muscular tension, and/or glaucoma and any other condition in which it is beneficial to modulate an opiate- and/or NMDA receptor.
摘要:
On peut ajouter aux dérivés d'alcaloïdes des isotopes radioactifs, des substances fluorescentes ou des substances absorbant les rayons X. Les alcaloïdes peuvent être utilisés aussi comme analgésiques, pour le traitement de polyarthrite et comme substance anti-inflammatoire postopératoire. Les nouveaux dérivés de formule $(6,)$où Y : O, S, N; X : N, O; n : 1-3; et (III) représentent un alcaloïde comprenant de l'isoquinoline, peuvent être préparés en faisant réagir un ou plusieurs alcaloïdes de formule (III) avec des agents d'alkylation.
