Synthesis and biological evaluation of 99mTc(CO)3-OH-PP-CS2 for brain receptor imaging
Introduction: 5-HT1A receptor is related with a variety of neuropsychiatric disorders. . In this study a phenolic analogue derived from DWAY [Desmethyl WAY-100635 (N-(2-(1-(4-(2-methoxyphenyl)piperazinyl)-ethyl))-N-(2-pyridinyl) cyclohexanecarboxamide)] is used to design the desired structure of 5-HT1A receptor imaging agents after labeling with [99mTc (CO) 3(H2O) 3] + cor...
متن کاملSynthesis and biologic evaluation of a novel serotonin 5-HT1A receptor radioligand, 18F-labeled mefway, in rodents and imaging by PET in a nonhuman primate.
UNLABELLED Serotonin 5-HT1A receptors have been implicated in disorders of the central nervous system and, therefore, are being studied by PET. Efforts are under way to improve in vivo stability of 5-HT1A agents currently in human use (11C-labeled N-(2-[4-(2-methoxyphenyl)-1-piperazinyl]ethyl-N-(2-pyridinyl)cyclohexanecarboxamide [11C-WAY-100635], 4-(2'-methoxyphenyl)-1-[2'-(N-2''-pyridinyl)-p-...

The pharmacological properties of cyclohexanecarboxylic acid, {2-[4-(2-bromo-5-methoxybenzyl)piperazin-1-yl]ethyl}-(2-trifluoromethoxyphenyl)amide (Rec 27/0224), and cyclohexanecarboxylic acid, (2-methoxy-phenyl)-{2-[4-(2-methoxyphenyl)-piperazin-1-yl]ethyl}amide (Rec 27/0074), were characterized using radioligand displacement and guanosine 5'-O-(3-[35S]thiotriphosphate) ([35S]GTPgammaS) bindin...
متن کاملPharmacological properties of 3-amino-5,6,7,8-tetrahydro-2-[4-[4-(quinolin-2-yl)piperazin-1-yl]butyl]quinazolin-4(3H)-one (TZB-30878), a novel therapeutic agent for diarrhea-predominant irritable bowel syndrome (IBS) and its effects on an experimental IBS model.
3-Amino-5,6,7,8-tetrahydro-2-[4-[4-(quinolin-2-yl)piperazin-1-yl]butyl]quinazolin-4(3H)-one (TZB-30878) is a novel compound with both 5-hydroxytryptamine (5-HT)(1A) agonism and 5-HT(3) antagonism effects. We hypothesized that TZB-30878 might have benefits from these dual effects as a medication for diarrhea-predominant irritable bowel syndrome (d-IBS), and these studies were designed to confirm...
