CHAETOMIN Usage And Synthesis

Uses

Chetomin is an antibacterial agent and inhibitor of HIF.

Definition

ChEBI: An organic heteropentacyclic compound of the class of epipolythiodioxopiperazine. Isolated from Chaetomium globosum and Farrowia seminuda, it exhibits immunosuppressive activity.

Biochem/physiol Actions

Chetomin is a natural metabolite produced by several species of the genus Chaetomium. Chetomin is an epidithiodioxopiperazine known to disrupt the hypoxia-inducible factor (HIF) pathway. Chetomin blocks the interaction of HIF1α and HIF2α with transcriptional co-activators p300 and cAMP response element binding (CREB) binding protein (CBP), thereby attenuating hypoxia-inducible transcription. Disrupting the ability of tumors to adapt to hypoxia leads to decreased tumor growth and can serve as an antitumor stratagy. Chetomin also suppresses the proliferation of LPS-induced mouse spleen lymphocytes.
