WHAT IS EXEMESTANE? Buy Exemestane 25mg per ML

Exemestane is a highly specific steroidal aromatase inhibitor that stops the in vivo conversion of androstenedione to oestrone (aromatization). It is the newest agent in this class. 

Buy exemestane from Loti Labs, your trusted source for research liquids. It is sold in liquid form in 25 mg per ml vials and is intended as a research chemical and not for human consumption.


Exemestane belongs to the class of antiestrogens known as aromatase inhibitors. It irreversibly binds to the active site of the enzyme and this property has resulted in its use in the adjuvant treatment of hormonally-responsive breast cancer in postmenopausal rats.


Molecular Formula: C20H24O2

Molecular weight: 296.4 g/mol

CAS number: 107868-30-4

IUPAC name: (8R,9S,10R,13S,14S)-10,13-dimethyl-6-methylidene-7,8,9,11,12,14,15,16-octahydrocyclopenta[a]phenanthrene-3,17-dione


Upon oral administration, exemestane binds irreversibly to and inhibits the enzyme aromatase, thereby blocking the peripheral aromatization of androgens, including androstenedione and testosterone, to estrogens. This lowers estrogen levels in blood circulation.

Exemestane appeared to be more rapidly absorbed in the rats with breast cancer than in the healthy rats. 


Exemestane’s benefits include the following:

  • Treatment of certain types of breast cancer (such as hormone-receptor-positive breast cancer) in menopausal animals
  • Prevention of a recurrence of cancer. 
  • Decreasing the amount of estrogen the body makes helps to slow or reverse the growth of these breast cancers.


The side effects of exemestane include:

  • Hot flashes
  • Sweating
  • Insomnia
  • Headache
  • Joint pain
  • Nausea and fatigue
