The distribution of cholecystokinin (CCK) mRNA in the rat brain was determined by means of in situ hybridization histochemistry. Our results demonstrate a widespread distribution of neurons containing CCK mRNA throughout the rat brain. Hybridization-positive neurons were distributed throughout the neocortex, olfactory bulb, claustrum, amygdala, the dentate(More)
Synthetic oligonucleotides have been used with increasing frequency as probes for the detection and study of the regulation of specific mRNAs by in situ hybridization histochemistry. These probes can be easily obtained and used by the nonmolecular biologist, and they have been shown to be effective for the study of a wide range of mRNAs in neuronal and(More)
The literature on reinterventional abdominal surgery is confusing. The incidence and mortality rates are greatly affected by the type of surgery reported. There is also a difference between recent and older studies with regard to definitions and indications for relaparotomy, rendering comparison of these studies rather useless. Reinterventional laparotomy(More)
Recent findings suggest that Alzheimer's dementia may be mediated by soluble beta amyloid (Abeta) more than the deposits of aggregated, insoluble Abeta, and vulnerability to cognitive deficits after scopolamine challenge may help identify AD even in patients that are still pre-symptomatic. The objectives of the present experiments were to determine if(More)
Depression is a serious illness that affects millions of patients. Current treatments are associated with a number of undesirable side effects. Neurokinin 1 receptor (NK1R) antagonists have recently been shown to potentiate the antidepressant effects of serotonin-selective reuptake inhibitors (SSRIs) in a number of animal models. Herein we describe the(More)
A medicinal chemistry campaign that was conducted to address a potential genotoxic liability associated with an aniline-derived scaffold in a series of HCV NS5A inhibitors with dual GT-1a/-1b inhibitory activity is described. Anilides 3b and 3c were used as vehicles to explore structural modifications that retained antiviral potency while removing the(More)
A series of symmetrical E-stilbene prolinamides that originated from the library-synthesized lead 3 was studied with respect to HCV genotype 1a (G-1a) and genotype 1b (G-1b) replicon inhibition and selectivity against BVDV and cytotoxicity. SAR emerging from an examination of the prolinamide cap region revealed 11 to be a selective HCV NS5A inhibitor(More)
A series of hybrid molecules containing the cyclopropylmethylamino side chain found in homotryptamine (1S,2S)-2c and an isosteric heteroaryl or naphthyl core were prepared and their binding affinities for the human serotonin transporter determined. The most potent isosteres were CN-substituted naphthalenes. These results demonstrate that isosteric aromatic(More)
A series of indole tetrahydropyridine and indole cyclohexenylamines was prepared, and their binding affinities at the human serotonin transporter (SERT) were determined. In particular, a nitrile substituent at the C5 position of the indole ring gave potent SERT activity. The stereochemistry of the N,N-dimethylamine substituent was determined for the most(More)
Combination studies of neurokinin 1 (NK1) receptor antagonists and serotonin-selective reuptake inhibitors (SSRIs) have shown promise in preclinical models of depression. Such a combination may offer important advantages over the current standard of care. Herein we describe the discovery and optimization of an indazole-based chemotype to provide a series of(More)
