Biochem/physiol Actions
Fadrozole is a nonsteroidal aromatase inhibitor. Fadrozole is a very potent and highly selective inhibitor of the aromatase enzyme system in vitro and estrogen biosynthesis in vivo. It inhibited the conversion of [4-14C]androstenedione to [4-14C]estrone by human placental microsomes in a competitive manner (Ki = 1.6 nM). At a substrate concentration 3-fold the Km, Fadrozole was 180 times more potent, as an inhibitor, than aminoglutethimide (Cat. No. A9657), exhibiting half-maximal inhibition at 1.7 nM as compared to 0.3 μM. In vivo, Fadrozole lowered ovarian estrogen synthesis by gonadotropin-primed, androstenedione treated, immature rats by 90% at a dose of 260 μg/kg (PO). In vivo, Fadrozole leads to sequelae of estrogen deprivation (e.g. regression of DMBA-induced mammary tumors) without causing adrenal hypertrophy in adult rats. It blocked aromatase by 50% in human breast cancer homogenates, live breast cancer cells, human placental microsomes, and porcine ovarian microsomes at concentrations of 0.008 to 0.02 μM.

Across vertebrate species, 17β-estradiol (E(2)) acts on the brain via both genomic and nongenomic mechanisms to influence neuronal physiology and behavior. Nongenomic E(2) signaling is typically initiated by membrane-associated estrogen receptors that modulate intracellular signaling cascades, including rapid phosphorylation of

Induction of all-male population in Siamese fighting fish, Betta splendens, has potential application in ornamental fish trade. In addition, the sexually dimorphic nature of aggressive behavior exhibited by this species has made it into an emerging model for behavioral studies.

Aldosterone is known to be involved in atherosclerosis and cardiovascular disease and blockade of its receptor was shown to improve cardiovascular function. It was, therefore, hypothesized that inhibition of aldosterone synthesis would also reduce atherosclerosis development. To test this hypothesis

A majority of birds are socially monogamous, providing exceptional opportunities to discover neuroendocrine mechanisms underlying preferences for opposite-sex partners where the sexes form extended affiliative relationships. Zebra finches have been the focus of the most systematic program of research to

Local aromatization of testosterone into 17beta-estradiol (E(2)) is often required for the physiological and behavioral actions of testosterone. In most vertebrates, aromatase is expressed in a few discrete brain regions. While many studies have measured brain aromatase mRNA or activity
