Hyperpolarization-activated cyclic nucleotide-gated (HCN) channels underlie the pacemaker currents in neurons (I(h)) and cardiac (I(f)) cells. As such, the identification and characterization of novel blockers of HCN channels is important to enable the dissection of their function in vivo. Using a new IonWorks HT electrophysiology assay with human HCN1 and… (More)
Alzheimer's disease (AD) is a debilitating disease widely thought to be associated with the accumulation of beta amyloid (Abeta) in the brain. Inhibition of gamma-secretase, one of the enzymes responsible for Abeta production, may be a useful strategy for the treatment of AD. Described below is a series of gamma-secretase inhibitors designed from a scaffold… (More)
