  摘要：

  The (E)-2-(4-pyridylmethylene)-1-indanones (E)-1-(E)-5[(E)-1, H; (E);2, 4-OCH3; (E)-3, 5-OCH3; (E)-4, 4-OH; (E)-5,5-OH] were obtained by aldol condensation of the corresponding 1-indanones with 4-pyridinecarboxaldehyde, and in case of the OH compound (E)-4 subsequent ether cleavage of (E)-2. The synthesis of the (Z)-isomers (Z)-1-(Z)-3 [(Z)-1, H; (Z)-2, 4-OCH3; (Z)-3, 5-OCH3] was accomplished by UV irradiation of the corresponding (E)-isomers. Catalytic hydrogenation of (E)-1-(E)-3 gave the 2-(4-pyridylmethyl)-1-indanones 6-8 (6, H; 7, 4-OCH3; 8, 5-OCH3). The 2-(4-pyridylmethyl)-substituted indans 11-13 (11, H; 12, 4-OCH3; 13, 5-OCH3) and the tetralins 16-19 (16, H; 17, 5-OCH3; 18, 6-OCH3; 19, 7-OCH3) were obtained by reduction of the corresponding ketones using N2H4/KOH. The 2-(4-pyridylmethyl)-substituted indanones 9 (4-OH) and 10 (5-OH), indans 14 (4-OH) and 15 (5-OH), and tetralins 20-22 (20, 5-OH; 21, 6-OH; 22, 7-OH) were synthesized by ether cleavage of the corresponding OCH3 compounds. All compounds showed inhibition of human placental aromatase exhibiting relative potencies from 0.9 [(E)-4] to 163 [18; aminoglutethimide (AC) potency E 1]. Compounds 13 and 18 showed competitive type of inhibition and a type II difference spectrum, indicating the interaction of the pyridyl-N with the central Fe(III) ion of the cytochrome P450 heme component. Only the OH-substituted indans and tetralins inhibited bovine adrenal desmolase with maximum activity shown by 20 and 22 (12% inhibition, 25 mu M; AG, 53 % inhibition, 25 mu M). In vivo, however, all tested aromatase inhibitors (6, 8, 10, 14, 15, 18 and 20) were less active than AG concerning the inhibition of the uterotrophic activity of androstenedione (6, 8, 10, 15), the reduction of the plasma estradiol concentration (14, 20), and the mammary carcinoma (MC) inhibiting properties (18, 20; androstenedione-stimulated juvenile rats, pregnant mares' serum gonadotropin-primed rats as well as dimethylbenzanthracene-induced MC of the Sprague-Dawley rat, postmenopausal experiment). Since no affinity to the estrogen receptor was demonstrated (20), estrogenic effects as a cause for the poor tumor inhibiting activity have to be excluded.

  (EN) The present invention provides a novel industrially or economically preferable process for production of a hydrogen halogenide salt of a Donepezil derivative having an excellent pharmacological action as medicament, namely, reaction of 1-indanone derivative with carbonate ester to obtain 2-alkoxycarbonyl-1-indanone derivative, followed by reaction with halogenated (4-pyridyl)methyl or a salt thereof and decarboxylation successively to obtain 2-(4-pyridyl)methyl-1-indanone derivative, then reaction with halogenated benzyl to obtain quaternary ammonium salt, then reduction, and synthetic intermediate thereof. In the formulae step 1, step 2, step 3 and step 5 R1 represents a hydrogen atom or lower alkoxy; n represents an integer of 1 to 4; R2 represents lower alkyl group; and X represents a halogen atom.(FR) Cette invention a trait à un nouveau procédé, préférable au plan industriel ou économique, de production d'un sel d'halogénure d'hydrogène d'un dérivé de Donépézil doué d'une remarquable activité médicamenteuse. Ce procédé consiste à faire réagir un dérivé de 1-indanone avec un ester de carbonate pour obtenir un dérivé de 2-alcoxycarbonyl-1-indanone, ensuite à faire réagir avec un (4-pyridyl)méthyle halogéné ou un sel de celui-ci et à procéder à une décarboxylation pour obtenir un dérivé de 2-(4-pyridyl)méthyl-1-indanone. On fait ensuite réagir avec un benzyle halogéné pour obtenir un sel d'ammonium quaternaire et l'on procède enfin à une réduction. L'invention concerne également des intermédiaires de synthèse de ce sel. Etape 1 Etape 2 Etape 3 Etape 4 Dans ces formules R1 représente un atome d'hydrogène ou un alcoxy de faible poids moléculaire, n représente un nombre entier d'une valeur comprise entre 1 et 4, R2 représente un groupe alkyle de faible poids moléculaire et X représente un atome d'halogène.
