product name: exemestane
cas number: 107868-30-4
superlist name: exemestane
molecular structure: molecular structure of 107868-30-4 (6-methyleneandrosta-1,4-diene-3,17-dione)
formula: c20h24o2
aromasin (exemestane acetate) is one of those weird compounds that nobody really knows what to do with. it's a third generation aromatase inhibitor (ai) just like arimidex and femera. the third generation aromatase inhibitors, used in the treatment of metastatic breast cancer and used as aid in the treatment of early breast cancer.
|
1. aromasin is one of the most powerful estrogen suppressing compounds. |
|
2. aromasin is one of the best compounds to lower the aromatizing effect of steroids. |
|
3. aromasin is available for body builders taking anabolic steroids. |
|
4. it acts by blocking the enzyme aromatase, subsequently blocking the production of estrogen. |
|
5. aromasin is also a kind of .antineoplastic (hormonal) raw materials. |
Function
exemestane (trade name aromasin) is a drug used to treat breast cancer. it is a member of the class of drugs known as aromatase inhibitors. some breast cancers require estrogen to grow. those cancers have estrogen receptors (ers), and are called er-positive. they may also be called estrogen-responsive,hormonally-responsive, hormone-receptor-positive. aromatase is an enzyme that synthesizes estrogen. aromatase inhibitors block the synthesis of estrogen. this lowers the estrogen level, and slows the growth of cancers.
Application
1. exemestane is an oral steroidal aromatase inhibitor that is used in er-positive breast cancer in addition to surgery and/or radiation in post-menopausal women.
2. it acts as a false substrate for the aromatase enzyme, and is processed to an intermediate that binds irreversibly to the active site of the enzyme causing its inactivation, an effect also known as "suicide inhibition."
3. by being structurally similar to enzyme targets, exemestane permanently binds to the enzymes, preventing them from converting androgen into estrogen
