macbecin I
Sign in to saveAlso known as macbecin
Macbecins are a pair of chemical compounds in the ansamycin family of antibiotics. They are designated macbecin I and macbecin II and they were first isolated from actinomycete bacteria. Macbecin possesses antitumor properties. In vitro studies have shown that macbecins are effective in the eradication of Gram-positive bacteria, fungi, and protozoa including Tetrahymena pyriformis. ==Structure== Macbecins have an unusual macrocyclic lactam structure. The two variants, macbecin I and II, correspond to the oxidized 1,4-benzoquinone and reduced hydroquinone, respectively.

==Mechanism of action== Macbecins mechanism of action is in part due to heat shock protein Hsp90 protein inhibition.
