The title compound, [(2S,5R,6S,9R)-6-isopropyl-9-methyl-1,4-dioxaspiro-[4.5]dec-2-yl]methyl 3,5-dinitro-benzoate, C(20)H(26)N(2)O(8), was synthesized as part of a study of three-carbon stereochemical systems. The crystallographic assignment of the absolute stereochemistry is consistent with having started with (-)-menthone, the acetal carbon is R and the secondary alcohol is S. This brings the ...
Phthaloylimidoalkyl derivatives (1a, 1b) were treated with isopropylamine to give 3-benzamido-1-(4-(2-methoxyphenyl)piperazin-1-yl)]propyl-2-isopropyl carboxamide (3a) and 4-benzamido-1-(4-(2-methoxyphenyl)piperazin-1-yl)butyl-2-isopropyl carboxamide (3b). The compounds were unequivocally characterized by IR, NMR and MS spectra and elemental analysis. Carrageenan-induced rat paw assay was used ...
The present study demonstrates the utility of an in vitro-in vivo correlative approach in the selection of an optimum prodrug candidate of L-767,679 (N-([7-(piperazin-1-yl)-3,4-dihydro-1(1H)-isoquinolinone-2-yl]acetyl)-3(S)-(ethynyl)-beta-alanine), a potent fibrinogen receptor antagonist. As an initial screening step, a comparative in vitro hepatic metabolism study was conducted for L-767,679 a...
A series of N-azabicycloalkyl-1-alkyl-2-oxo-1,2-dihydro-3-quinolinecarboxamides were synthesized and tested for serotonin 5-HT4 receptor-stimulating effects in the regulation of electrically-evoked contraction in guinea pig muscle. Among them, N-azabicycloalkyl-1-isopropyl-2-oxo-1,2-dihydro-3-quinolinecarboxamide (8c, 9c, 10c, 11c, 12c) exhibited potent serotonin 5-HT4 receptor-stimulating acti...
