Abstract : The rice species Oryza sativa is considered to be a model plant because of its small genome size, extensive genetic map, relative ease of transformation and synteny with other cereal crops. Here we report the essentially complete sequence of chromosome 1, the longest chromosome in the rice genome. We summarize characteristics of the chromosome structure and the biological insight gained from the sequence. The analysis of 43.3 megabases (Mb) of non-overlapping sequence reveals 6,756 protein coding genes, of which 3,161 show homology to proteins of Arabidopsis thaliana, another model plant. About 30% (2,073) of the genes have been functionally categorized. Rice chromosome 1 is (G + C)-rich, especially in its coding regions, and is characterized by several gene families that are dispersed or arranged in tandem repeats. Comparison with a draft sequence indicates the importance of a high-quality finished sequence.

Abstract : The two mono-hydroxylated metabolites of 9-amino-2,3,5,6,7,8-hexahydro-1H-cyclopenta[b]quinoline monohydrochloride monohydrate (NIK-247), which is a new drug for the treatment of dementia, were synthesized to determine their chemical structures. Reduction of two tricyclic ketones, 9-amino-1,2,3,5,6,7-hexahydro-8H-cyclopenta[b]quinolin-8-one and 9-amino-2,3,5,6,7,8-hexahydro-1H-cyclopenta[b]-quinolin-1-one, with NaBH4 afforded the corresponding racemic alcohols. The optically active mono-hydroxylated metabolites, (+)-9-amino-2,3,5,6,7,8-hexahydro-1H-cyclopenta[b]quinolin-8-ol and (+)-9-amino-2,3,5,6,7,8-hexahydro-1H-cyclopenta[b]quinolin-1-ol, were obtained by optical resolution of each racemic alcohol using (+)-di-p-toluoyl-D-tartaric acid.

Abstract : The two dihydroxylated metabolites of 9-amino-2,3,5,6,7,8-hexahydro-1H-cyclopenta[b]quinoline monohydrochloride monohydrate (NIK-247), which is a new drug for the treatment of dementia, were synthesized to determine their chemical structures.

(+)-9-Amino-2,3,5,6,7,8-hexahydro-8-hydroxy-1H-cyclopenta[b]quinolin+ ++-1-one was obtained by optical resolution of the corresponding racemic hydroxyketone using (-)-di-p-toluoyl-L-tartaric acid. The optically active dihydroxylated metabolites were obtained by reduction of the (+)-8-hydroxy-1-one with NaBH4.

Title : A novel ligand, [125I]BQ-3020, reveals the localization of endothelin ETB receptors - Kobayashi_1993_Eur.J.Pharmacol_235_95

Abstract : The precise localization of an endothelin (ET) receptor subtype, the ETB receptor, in porcine lung was elucidated by in vitro microautoradiography using a novel ETB-selective radioligand, [125I]BQ-3020 ([125I-Tyr]-N-acetyl-Leu-Met-Asp-Lys-Glu-Ala-Val-Tyr-Phe-Ala-His-Leu-Asp -Ile-Ile-Trp). Of the labeled native ET isopeptides, [125I]ET-3 is selective for ETB receptors. However, [125I]ET-3 was not suitable for autoradiography due to its high degree of non-specific binding. On the other hand, [125I]BQ-3020 showed extremely low non-specific binding on autoradiography. The distribution of [125I]BQ-3020 binding in porcine lung was clearly different from that of [125I]ET-1, which showed more widespread binding than [125I]BQ-3020 due to a high affinity to both ETA and ETB receptors. [125I]BQ-3020 was found to bind to parenchyma, parasympathetic ganglia, pulmonary and submucosal plexuses, but bound only slightly to circular smooth muscle layers and the epithelium of airway tracts. Although [125I]ET-1 bound to the smooth muscle layer of all blood vessels, the binding of [125I]BQ-3020 differed among blood vessels. [125I]BQ-3020 binding in blood vessels paralleled acetylcholinesterase activity, suggesting that ETB receptors in blood vessels are located on parasympathetic nerves. Thus, the radioligand [125I]BQ-3020 is very useful for studying the precise localization of ETB receptors.
