With several notable exceptions, interest in the area of multiple molecular forms of phosphodiesterase remained relatively dormant during the decade following Thompson's discovery of more than one phosphodiesterase in brain in 1971. Within the last several years, however, over 20 novel agents have been identified that exert selective inhibitory effects on(More)
Several beta-carbolines, isoquinolines, imidazopyridines , and canthin -6-ones prepared in biomimetic fashion were tested for their ability to bind to the benzodiazepine receptor. Methyl isoquinoline-3-carboxylate, methyl 6,7- dimethoxyisoquinoline -3-carboxylate (3b) 1-phenyl-3- carbomethoxyimidazopyridine , (6B,) and canthin -6- one ( 13a ) bound with(More)
The benzodiazepine receptor antagonist 3-hydroxymethyl-beta-carboline, which blocks several of the pharmacological actions of benzodiazepines, induces a dose-dependent increase in sleep latency in the rat. Furthermore, at a low dose that by itself does not affect sleep, 3-hydroxymethyl-beta-carboline blocks sleep induction by a large dose of flurazepam. The(More)
We have prepared a series of tetrahydro-beta-carbolines (TH beta C), beta-carbolines (beta-C), and other nitrogen heterocycles and evaluated them in vitro with respect to their ability to bind to benzodiazepine receptors. The fully aromatic beta-C's were more potent than their corresponding TH beta C derivatives. When substituents possessing a carbonyl(More)
As peripheral blood has surpassed bone marrow as a predominant source of stem cells for transplantation, use of the cytokine granulocyte colony-stimulating factor (G-CSF) to mobilize peripheral blood stem cells (PBSCs) is increasing. Issues regarding potential genotoxic effects of even short-term, low-dose G-CSF treatment for the healthy donors have been(More)
