摘要:
Novel compounds that find use as imaging agents within nuclear medicine applications (PET imaging) for imaging of cardiac innervation are disclosed. These PET based radiotracers may exhibit increased stability, decreased NE release (thereby reducing side effects), improved quantitative data, and/or high affinity for VMAT over prior radiotracers. Methods of using the compounds to image cardiac innervation are also provided. In some instances the compounds are developed by derivatizing certain compounds with 18 F in a variety of positions: aryl, alkyl, a keto, benzylic, beta-alkylethers, gamma-propylalkylethers and beta-proplylalkylethers. Alternatively or additionally, a methyl group a is added to the amine, and/or the catechol functionality is either eliminated or masked as a way of making these compounds more stable.
摘要:
The present disclosure is directed to compounds, diagnostic agents, and related methods. In some cases, methods for treating patients are provided. More specifically, the disclosure provides compounds, diagnostic agents, and kits for detecting and/or imaging and/or monitoring elastin rich tissues. In addition, the disclosure provides methods of detecting and/or imaging and/or monitoring the presence of coronary plaque, carotid plaque, iliac/femoral plaque, aortic plaque, renal artery plaque, plaque of any arterial vessel, aneurism, vasculitis, other diseases of the arterial wall, and/or damage or structural changes in ligaments, uterus, lungs or skin, as indicated by changes in total vessel wall area, internal lumen size, and exterior arterial perimeter.
摘要:
The present invention is directed, in part, to compounds and methods for diagnostic imaging, comprising administering to a patient a contrast agent which has an overall negative charge.
摘要:
The present disclosure relates to a solid-phase process for the production of radiolabeled tracers, in particular for the production of 18 F-labeled compounds which may be used as Positron Emission Tomography (PET) radiolabeled tracers. The disclosure also relates to radiopharmaceutical kits comprising precursors to the radiolabeled tracers, which can be converted to the radiolabeled tracers using the processes described herein.
摘要:
The present disclosure is directed, in part, to compounds and methods for imaging myocardial perfusion, comprising administering to a patient a contrast agent which comprises a compound that binds MC-1, and an imaging moiety, and scanning the patient using diagnostic imaging.
摘要:
Novel ß1 adrenoreceptor ligands that find use as imaging agents within nuclear medicine applications (e.g., PET imaging and SPECT imaging) are provided. Methods of imaging, including methods of imaging congestive heart failure, are also provided. The novel compounds may exhibit high affinity and selectivity, minimal metabolism, minimal non-specific binding and have a favorable log P value (1-AR selective ligands are conjugated to an imaging moiety in such a way that it does not impact the antagonist affinity and their use. In other instances, the conjugation may be directly to the antagonist at several sites that will not impact affinity. In further instances, the conjugation may be by means of a linking group, which can be used to alter the pharmacokinetics and clearance of the complex.
摘要:
The present invention is directed, in part, to compounds and methods for imaging the central nervous system or cancer, comprising administering to a subject a contrast agent which comprises a compound that binds MC-I, and an imaging moiety, and scanning the subject using diagnostic imaging.
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.
