Vorozole is an imidazole based competitive inhibitor of the aromatase enzyme. It underwent clinical testing for evaluation for use as an antineoplastic agent; however it was withdrawn from testing when no difference was detected in the duration of median survival as compared to the progestational agent megestrol acetate and research instead focused on the other third generation aromatase inhibitors anastrozole, letrozole and exemestane.
It is selective.
There's a monster name of Frazzle
Who's a good friend of mine
He looks ferocious, but he's really fine
Go up and ask him for his autograph
He'd be so happy that he'd start to laugh
He goes Argh! That's how he laughs
He goes Argh! That means he's glad
He goes Argh! That means he's having
The greatest time that he ever had
Now you know my buddy Frazzle
He's got fangs on his jaws
His fur is orange, and he's got these claws
He looks so mean that he could scare a crowd
But if you tickle him he laughs out loud
He goes Argh! That's how he laughs
He goes Argh! That means he's glad
He goes Argh! That means he's having
The greatest time that he ever had
Mr. Frazzle has emotions like the rest of us do
Sometimes he feels low down and ugly, too
And then the tears begin to fill his eyes
It's so pathetic when a monster cries
He goes Argh! That's how he cries
He goes Argh! That means he's sad
He goes Argh! That means he's having
The lowest time that he ever had
Argh! That means he's hungry
Argh! That means he's hot
Argh! That means he's sleepy
Argh! That means he's not
Argh! That means yes
Argh! That means no
Argh! Means thank you for the dinner
But, it's getting very late and I really must go
Argh!
