- N′-3-(Trifluoromethyl)phenyl Derivatives of N-Aryl-N′-methylguanidines as Prospective PET Radioligands for the Open Channel of the N-Methyl- d -aspartate (NMDA) Receptor: Synthesis and Structure-Affinity Relationships
-
N-Methyl-d-aspartate (NMDA) receptor dysfunction has been linked to several neuropsychiatric disorders, including Alzheimer's disease, epilepsy, drug addiction, and schizophrenia. A radioligand that could be used with PET to image and quantify human brain NMDA receptors in the activated "open channel" state would be useful for research on such disorders and for the development of novel therapies. To date, no radioligands have shown well-validated efficacy for imaging NMDA receptors in human subjects. In order to discover improved radioligands for PET imaging, we explored structure-affinity relationships in N′-3-(trifluoromethyl)phenyl derivatives of N-aryl-N′-methylguanidines, seeking high affinity and moderate lipophilicity, plus necessary amenability for labeling with a positron-emitter, either carbon-11 or fluorine-18. Among a diverse set of 80 prepared N′-3-(trifluoromethyl)phenyl derivatives, four of these compounds (13, 19, 20, and 36) displayed desirable low nanomolar affinity for inhibition of [3H](+)-MK801 at the PCP binding site and are of interest for candidate PET radioligand development.

- Novel and selective 5-HT(2C/2B) receptor antagonists as potential anxiolytic agents: Synthesis, quantitative structure - Activity relationships, and molecular modeling of substituted 1-(3- pyridylcarbamoyl)indolines
-
The synthesis, biological activity, and molecular modeling of a novel series of substituted 1-(3-pyridylcarbamoyl)indolines are reported. These compounds are isosteres of the previously published indole urea 1 (SB- 206553) and illustrate the use of aromatic disubstitution as a replacement for fused five-membered rings in the context of 5-HT(2C/2B) receptor antagonists. By targeting a region of space previously identified as sterically allowed at the 5-HT(2C) receptor but disallowed at the 5-HT(2A) receptor, we have identified a number of compounds which are the most potent and selective 5-HT(2C/2B) receptor antagonists yet reported. 46 (SB-221284) was selected on the basis of its overall biological profile for further evaluation as a novel, potential nonsedating anxiolytic agent. A CoMFA analysis of these compounds produced a model with good predictive value and in addition good qualitative agreement with both our 5-HT(2C) receptor model and our proposed binding mode for this class of ligands within that model.
