Product Description
Information
Aminoglutethimide Aminoglutethimide (BA-16038, NSC-330915) is an aromatase inhibitor with IC50 of 10 μM. In vitro
Aminoglutethimide displays aromatase inhibition in vitro assay with human placental aromatase, which is an enzyme involved in the conversion of androgens into estrogens, and an important target for the endocrine treatment of breast cancer. Aminoglutethimide inhibits ACTH receptor (ACTH-R) mRNA expression in ovine adrenocortical cells in a time-dependent fashion. Aminoglutethimide significantly suppresses steroid secretion and the baseline ACTH-R mRNA expression in a dose-dependent fashion (300 μM AG, 5±1%; 30 μM AG, 64±1%; 3 μM AG, 108±19% compared with control cells, 100±11%) by affecting the gene expression or by decreasing transcript accumulation via an effect on RNA stability, in the human NCI-h295 adrenocortical carcinoma cell line, which expresses functional ACTH receptors and produces steroids of the glucocorticoid, mineralocorticoid and androgen pathway. Aminoglutethimide inhibits aromatase in a dose-dependent fashion with IC50 of 13 μM in 6 breast tumor homogenates, placental aromatase with IC50 of 6 μM and hypothalamic aromatase with IC50 of 8 μM.
In vivo
Aminoglutethimide accelerates its own metabolism from a basal value of 2.6±0.3 (S.E.) liters/24 hours to 5.3±1.4 liters/24 hours after 1 to 2 weeks of Aminoglutethimide administration, and markedly accelerates the metabolism of the synthetic glucocorticoid and dexamethasone, from basal values of 145±26.6 liters/24 hours to 568±127 liters/24 hours (p < 0.02) after 2 weeks of Aminoglutethimide administration. Aminoglutethimide (150 mg/kg) abolishes the induction of ornithine decarboxylase (ODC) and almost depletes the gonads and plasma of progesterone or testosterone elicited by human chorionic gonadotropin (hCG) in the ovary of adult female mice and the testis of immature male mice, which is related to an inhibition of cAMP-dependent protein kinase (IC50 287 μM) rather than blockade of the steroidogenic pathway.
