  New aromatase inhibitors. Synthesis and biological activity of pyridyl-substituted tetralone derivatives

  摘要：

  The (E)-2-(4-pyridylmethylene)-1-tetralones 1-7 (1, H; 2, 5-OCH3; 3, 6-OCH3; 4, 7-OCH3; 5, 5-OH; 6, 6-OH; 7, 7-OH) were obtained by aldol condensation of the corresponding 1-tetralones with 4-pyridinecarboxaldehyde, and in the case of the OH compounds 5 and 7 subsequent ether cleavage of the OCH3-substituted 2-(4-pyridylmethylene)-1-tetralones. Catalytic hydrogenation of 1-4 gave the 2-(4-pyridylmethyl)-1-tetralones 8-11 (8, H; 9, 5-OCH3; 10, 6-OCH3; 11, 7-OCH3). Subsequent ether cleavage of 9-11 led to the corresponding OH compounds 12-14 (12, 5-OH; 13, 6-OH; 14, 7-OH). The enantiomers of 11 and 12 were separated semipreparatively by HPLC on triacetylcellulose. All compounds (1-14) showed an inhibition of human placental aromatase exhibiting relative potencies from 2.2 to 213 [compounds 6 and (+)-12, respectively; aromatase inhibitory potency of aminoglutethimide (AG) = 1]. The compounds exhibited no or only a weak inhibition of desmolase [cholesterol side chain cleavage enzyme; maximum activity shown by 12, 23 % inhibition (25-mu-M); AG, 53 % inhibition (25-mu-M)]. In vivo, however, the compounds were not superior to AG as far as the reduction of the plasma estradiol concentration and the mammary carcinoma (MC) inhibiting properties are concerned (PMSG-primed SD rats as well as DMBA-induced MC of the SD rat, pre- and postmenopausal experiments, and the transplantable MXT-MC of the BD2F1 mouse). This is due to a fast decrease of the plasma E2 concentration inhibiting effect as could be shown by a kinetic experiment. In addition, select compounds inhibited rat ovarian aromatase much less than human placental aromatase (12, factor of 10). Estrogenic effects as a cause for the poor in vivo activity of the test compounds could be excluded, since they did not show affinity for the estrogen receptor.

  N-Oxide formation causes loss of aromatase inhibitory activity of pyridyl-substituted tetrahydronaphthalenes

  摘要：

  N-Oxidation plays a role in the metabolism of numerous pyridine-substituted drugs. In order to examine the effect of a possible N-oxidation on the activity of nonsteroidal aromatase inhibitors, three potent pyridine-substituted tetrahydronaphthalenes were converted to their corresponding N-oxides. Using human placental aromatase, it was shown that N-oxidation causes a nearly complete loss of aromatase inhibitory activity.

  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.
