The present study describes the pharmacological profile of the putative antipsychotic drug Lu 35-138 ((+)-(S)-3-{1-[2-(1-acetyl-2,3-dihydro-1H-indol-3-yl)ethyl]-3,6-dihydro-2H-pyridin-4-yl}-6-chloro-1H-indole). The in vitro receptor profile of Lu 35-138 revealed high affinity (K(i)=5 nM) and
OBJECTIVE
To study the neuroprotective effect of experimental retinal detachment (RD) on photoreceptor degeneration in rd1 mice.
METHODS
RD was produced in the eyes of rd1 mice at postnatal day (P) 9. These eyes were collected and compared to controls without RD. The effects of RD on retinal
Our structure-activity relationship studies with N(6)-(2-(4-(1H-indol-5-yl)piperazin-1-yl)ethyl)-N(6)-propyl-4,5,6,7-tetrahydrobenzo[d]thiazole-2,6-diamine derivatives led to development of a lead compound (-)-21a which exhibited very high affinity (Ki, D2 = 16.4 nM, D3 = 1.15 nM) and full agonist
In nearly every species examined, administration of the persistent environmental pollutant, 2,3,7,8-tetrachlorodibenzo-p-dioxin (dioxin, TCDD) causes profound immune suppression and thymic atrophy in an aryl hydrocarbon receptor (AhR) dependent manner. Moreover, TCDD alters the development and
Glycogen synthase kinase (GSK)-3 modulates the production of inflammatory cytokines. Because bleomycin (BLM) causes lung injury, which is characterized by an inflammatory response followed by a fibrotic degeneration, we postulated that blocking GSK-3 activity with a specific inhibitor could affect
In our efforts to develop hybrid compounds of curcumin and melatonin as potential disease-modifying agents for Alzheimer's disease (AD), a potent lead hybrid compound, Z-CM-I-1, has been recently identified and biologically characterized in vitro. In this work, we report the in vivo effects of
The alternative pathway (AP) of the complement system is a key contributor to the pathogenesis of several human diseases including age-related macular degeneration, paroxysmal nocturnal hemoglobinuria (PNH), atypical hemolytic uremic syndrome (aHUS), and various glomerular diseases. The serine
Melatonin is a free radical scavenger and antioxidant. This indol is reported to efficiently scavenge both hydroxyl and peroxyl radicals and it also reduces both in vitro and in vivo tissue damage due to oxidants which generate oxygen toxic radicals. Lipopolysaccharide (LPS) administration induces
N-acetylserotonin (NAS) is synthesized from serotonin by arylalkylamine N-acetyltransferase (AANAT), which is predominantly expressed in the pineal gland and retina. NAS activates TrkB in a circadian manner and exhibits antidepressant effects in a TrkB-dependent manner. It also enhances neurogenesis
There is a great deal of interest in neurotrophin therapy to prevent neuronal degeneration. However, the blood-brain barrier presents a major hurdle in the use of peptide therapeutics. The goal of this study was to identify small molecule, cell-permeable nerve growth factor (NGF) activators.
Recently, the "discovery" of so called "rejuvenating" pills, has attracted much interest in the media and has raised irrational expectations among the elderly population. These so called "rejuvenating drugs" are dehydroepiandrosterone (DHEA), a steroid hormone secreted by the adrenal cortex, and
FK143 (4-[3-[3-[bis(4-isobutylphenyl)methylamino]benzoyl]-1H-indol-1-yl] - butyric acid) is a new non-steroidal inhibitor of steroid 5 alpha-reductase (5 alpha-reductase). The effects of FK143 on prostate size and histopathology of mature male beagle dogs were investigated and compared with those of
TrkB is the cognate receptor for brain-derived neurotrophic factor (BDNF), a member of the neurotrophin family involved in neuronal survival, neurogenesis and synaptic plasticity. BDNF has been shown to protect photoreceptors from light-induced retinal degeneration (LIRD) and to improve ganglion
Age-related changes in both morphological and neurochemical parameters of indol- and catecholaminergic system in the rat brain were examined. A qualitative histochemical survey of the occurrence of aberrant serotonergic fibers in the aged rat brain suggests region-specificity in the process of
Vascular endothelial growth factor (VEGF) is a key driver of the neovascularization and vascular permeability that leads to the loss of visual acuity in diabetic retinopathy and neovascular age-related macular degeneration. Our aim was to identify an orally active, selective small molecule kinase
