Pyrazolo[1,5-a]pyridine antiherpetics: Effects of the C3 substituent on antiviral activity
摘要:
A recently disclosed series of pyrazolo[1,5-a]pyridine inhibitors of herpes virus replication has been closely examined herein for effects of the C3 substituent on antiviral activity. Significant changes in activity are observed by alterations of the hetero-atom basicity and orientation of the group at C3. These results in combination with previous studies have served to further elaborate the minimal pharmacophore required for potency of this novel series of antiviral agents. During the course of these studies, several novel synthetic approaches were developed and are described. (c) 2007 Elsevier Ltd. All rights reserved.

of small molecule aminoimidazoles as potent and selective humanβ-secretaseinhibitors is reported. These analogues demonstrate low nannomolar potency for BACE1 in a FRET assay, exhibit comparable activity in a cell-based (ELISA) assay, and show >100× selectivity for the other structurally related aspartyl proteases BACE2, cathepsin D, renin, and pepsin. Our design strategy was supported by molecular
Palladium catalysis was used in Stille-type carbonylative cross-couplings employing Mo(CO)6 as the carbon monoxide source. Robust and convenient transformations were carried out in closed vessels at 100 °C, providing a set of diarylketones in good yields. Aryl triflates and bromides were used as coupling partners with aryl stannanes. Inclusion of the Mo(CO)6 destabilizing agent DBU made this protocol
The present invention is directed to 5-substituted 1,3-dihydro-2H-imidazo[4,5-b]pyridine-2-one derivatives which are positive allosteric modulators of the mGluR2 receptor, useful in the treatment or prevention of neurological and psychiatric disorders associated with glutamate dysfunction and diseases in which the mGluR2 receptor is involved. The invention is also directed to pharmaceutical compositions comprising these compounds and the use of these compounds and compositions in the prevention or treatment of such diseases in which metabotropic glutamate receptors are involved, such as schizophrenia.
