Abstract:
The effects in vitro of DDT, DDE and genistein on rat uterine purified aromatase activity were studied. It was established that all these compounds were competitive aromatase inhibitor. In the studies in vivo DDT and genistein decrease the rat ovarian and rat uterine aromatase activity. They were identified to decrease the quantity of the aromatase in these organs by inhibiting the expression of corresponding genes.

Adrenergic Agonists: Chemistry and Structure-Activity Relationship
Aromatic ring substitutions: Substituting the aromatic ring with –OH groups at positions 3 and 4 yields catecholamines (e.g., epinephrine), which have a high affinity for adrenoceptors. Hydrogen bonding between –OH groups and receptors enhances adrenergic activity.
