摘要:
The present invention is directed toward radiolabeled farnesyl-protein transferase inhibitor compounds which are useful to label FPTase in assays, whether cell-based, tissue-based or in whole animal. The tracers can also be used in competitive binding assays to obtain information on the interaction of unlabeled FTIs with FPTase.

摘要:
Novel radiolabeled cholecystokinin-A (CCK-A) antagonists have been developed which, after intravenous injection, localize in the pancreas as a result of specific binding to CCK-A receptors. These tracers, when labeled with appropriate radiohalogens, are useful as commercial diagnostic imaging radiopharmaceuticals and radiotherapeutic drugs.
摘要:
The present invention relates to antagonists of muscarinic acetylcholine receptors. More specifically, this invention contemplates highly selective antimuscarinic agents which are characterized as esters of 3-quinuclidinol and unsymmetrical alpha-disubstituted glycolic acids.These highly selective antimuscarinic agents permit efficacy at particular sites designated m.sub.1 -AChR without affecting the muscarinic acetylcholine receptors of other tissues characterized by sites designated m.sub.2 -AChR. Such efficacy requires lower quantities of the antagonist thereby lowering toxicity and other undesirable side effects.
摘要:
The present invention relates to particular radiolabeled Cannabinoid-1 (CB1) receptor modulators, and methods of using these modulators for labeling and diagnostic imaging of Cannabinoid-1 receptors in mammals, particularly humans. In addition, intermediates useful for the synthesis of the radiolabeled Cannabinoid-1 receptor modulators are also disclosed, as well as the processes for synthesizing the radiolabeled Cannabinoid-1 receptor modulators. Still further, formulations of the radiolabeled Cannabinoid-1 receptor compounds are described.
