A scalable cyanation of gem-difluoroalkenes to (hetero)arylacetonitrile derivatives was developed. This strategy features mild reaction conditions, excellent yields, wide substrate scope, and broad functional group tolerance. Significantly, in this reacti

The protein-protein interaction between the NMDA receptor and its intracellular scaffolding protein, PSD-95, is a potential target for treating ischemic brain diseases, neuropathic pain, and Alzheimer's disease. We have previously demonstrated that N-alkylated tetrapeptides are potent inhibitors of this interaction, and here, this template is exploited for the development of blood plasma-stable and cell-permeable inhibitors. Initially, we explored both the amino acid sequence of the tetrapeptide and the nature of the N-alkyl groups, which consolidated N-cyclohexylethyl-ETAV (1) as the most potent and selective compound. Next, the amide moieties of N-methylated ETAV were systematically replaced with thioamides, demonstrating that one of three amide bonds could be replaced without compromising the affinity. Subsequent optimization of the N-alkyl groups and evaluation of cell permeability led to identification of N-cyclohexylethyl-ETASV (54) as the most potent, plasma-stable and cell-permeable inhibitor, which is a promising tool in unraveling the therapeutic potential of the PSD-95/NMDA receptor interaction.

Histamine H1 and serotonin 5-HT2A receptors present in the CNS have been implicated in various neuropsychiatric disorders. 9-Aminomethyl-9,10-dihydroanthracene (AMDA), a conformationally constrained diarylalkyl amine derivative, has affinity for both of these receptors. A structure-affinity relationship (SAFIR) study was carried out studying the effects of N-methylation, varying the linker chain length and constraint of the aromatic rings on the binding affinities of the compounds with the 5-HT2A and H1 receptors. Homology modeling of the 5-HT2A and H1 receptors suggests that AMDA and its analogs, the parent of which is a 5-HT2A antagonist, can bind in a fashion analogous to that of classical H1 antagonists whose ring systems are oriented toward the fifth and sixth transmembrane helices. The modeled orientation of the ligands are consistent with the reported site-directed mutagenesis data for 5-HT2A and H1 receptors and provide a potential explanation for the selectivity of ligands acting at both receptors.
