Biological Activity for Chaetocin

Chaetocin is a histone methyltransferase SUV39H1 inhibitor (IC50 values are 0.8, 2.5 and 3 μM for dSU(VAR)3-9, mouse G9a and Neurospora crassa DIM5, respectively). Induces apoptosis in myeloma cell lines in vitro; exhibits antiproliferative activity in a mouse myeloma model in vivo.

Chaetocin potently inhibits cell proliferation and colony formation in a wide range of cancer cell lines (IC50 of 2-10 nM) and inhibits tumor growth by deregulating HIF-1α-mediated angiogenesis. Sensitizes glioblastoma multiforme cells to pro-apoptotic agents.

Chaetocin is also an inhibitor of the oxidative stress remediation enzyme thioredoxin reductase (TrxR), and so induces oxidative stress.

In addition, Chaetocin promotes osteogenic differentiation through modulating Wnt/Beta-catenin signaling in mesenchymal stem cells. Chaetocin treatment increased osteogenic ability and reduced adipogenic ability.
