alpha-amino acid derivatives were prepared as glycine transport inhibitors and their ability to block the uptake of [(14)C]-glycine in COS7 cells transfected with human glycine transporter-2 (hGlyT-2) was evaluated. An array of substituents at the chiral center was studied and overall, L-phenylalanine was identified as the preferred amino acid residue. Compounds prepared from l-amino acids were more
selectivities for M3 receptor over M2 receptor, indicating that the biphenyl-2-yl group is a novel hydrophobic replacement for the benzhydryl group in the muscarinic antagonist field. In this series, quinuclidin-4-yl biphenyl-2-ylcarbamate monohydrochloride (8l, YM-46303) exhibited the highest affinities for M1 and M3 receptors, and selectivity for M3 over M2 receptor. Compared to oxybutynin, YM-46303 showed

The present dislcosure provides amide-based, non-nucleoside compounds having antiviral activity against Hepacivirus, such as hepatitis C virus (HCV), methods and intermediates for synthesizing such compounds, and methods of using the compounds in a variety of contexts, including in the treatment and prevention of viral infections. The present dislcosure also provides methods for identifying amide-based, non-nucleoside compounds having antiviral activity.

The present disclosure provides amide-based, non-nucleoside compounds having an inhibitory activity against endogenous polymerases, such as polymerase alpha and polymerase gamma. This disclosure further provides uses of treating hyperproliferative diseases or disorders, such as benign or malignant neoplasms, and more specifically cancers that are sensitive to inhibition of polymerase alpha and polymerase gamma.
Starting from Fendiline and R-568, we identified a novel series of urea compounds as positive allosteric modulators of the calcium sensing receptor (CaSR), as part of a program to identify novel therapeutics for secondary hyperparathyroidism. Initially identified disubstituted ureas were converted to trisubstituted urea lead 20e, which was further modified to increase in vivo potency. Replacing a carbomethoxy
