Pharmacological suppression of leukotriene biosynthesis by inhibitors of 5-lipoxygenase (5-LO) is a strategy to intervene with inflammatory and allergic disorders. We recently presented 2-amino-5-hydroxy-1H-indoles as efficient 5-LO inhibitors in cell-based and cell-free assays. Structural optimization led to novel benzo[g]indole-3-carboxylates exemplified

One approach for the identification of therapeutic agents for Alzheimer's disease has focused on the research of alpha7 nAChR-selective agonists such as the partial agonists 3-(4-hydroxy,2-methoxybenzylidene)anabaseine (4OH-GTS-21) and, more recently, 2-[2-(4-bromophenyl)-2-oxoethyl]-1-methyl pyridinium (S 24795). An alternative approach for targeting alpha7

Allosteric modulation of ligand-gated ion channels can play important roles in shaping synaptic transmission. The function of the 5-hydroxytryptamine (serotonin) type 3 (5-HT(3)) receptor, a member of the Cys-loop ligand-gated ion channel superfamily, is modulated by a variety of compounds

We have investigated the absorption and emission spectrum of 5-hydroxyindole in the gas phase and in various solvents. 5-Hydroxyindole is the fluorophore of the non-natural amino acid 5-hydroxytryptophan, which has attracted recent interest as a novel intrinsic probe for protein
