MC1568 --- Class IIa HDAC Inhibitor

MC1568 is a potent and selective inhibitor of class IIa histone deacetylases (HDACs), with IC50 of 100 nM for maize HD1-A. It is 34-fold more selective for HD1-A than HD1-B, 176-fold more selective for class I HDACs. It exhibits tissue-selective inhibition between members of class II deacetylases in vivo; inhibits HDAC4 and HDAC5 in skeletal muscle and the heart without affecting HDAC3 activity. It arrests myogenesis through the stabilization of myocyte enhancer factor 2D (MEF2D)-HDAC3/4 complex. In a recent study of pancreatic explants, MC1568 enhances expression of Pax4, a key factor required for proper β-and δ-cell differentiation and amplifies endocrine β- and δ-cells.

How to use

In Vitro:

MC1568 was used at 5-10µM final concentration in vitro and cellular assays.

In Vivo:

MC1568 could be orally dosed to mice at 50 mg/kg once per day (formulation: 0.5% CMC, 5 mg/mL). It has an apparent tissue-selective HDAC inhibition. In skeletal muscle and heart, MC1568 inhibits the activity of HDAC4 and HDAC5 without affecting HDAC3 activity, thereby leaving MEF2-HDAC complexes in a repressed state.
