MC1568
MC1568, a derivative of (Aryloxopropenyl)pyrrolyl hydroxyamide, is a novel, potent and specific inhibitor of class II histone deacetylase (HDAC), including two subclasses IIa (HDAC4, HDAC5, HDAC6, HDAC7 and HDAC9) and IIb (HDAC6 and HDAC 10), that exhibits strong inhibition against maize class II HDAC with 50% inhibition concentration IC50 value of 22 μM. MC1568 has been found to tissue-selectively inhibits HDAC and arrest myogenesis in cultured muscle cells through three possible mechanisms, including decreasing the expression of myocyte enhancer factor 2D, stabilizing the HDAC-HDAC3-MEF2D complex and inhibiting the acetylation of differentiation-induced MEF2D. Moreover, MC1568 is able to interfere with RAR- and PPARγ-mediated differentiation-inducing signaling pathways.

Maize HD2, HD1-B, and HD1-A enzyme inhibition |
The enzyme liberated tritiated acetic acid from the substrate, which was quantified by scintillation counting. IC50 values are results of triple determinations. A 50 μL sample of maize enzyme (at 30 °C) was incubated (30 mins) with 10 μL of total [3H]acetate-prelabeled chicken reticulocyte histones (2 mg/mL). Reaction was stopped by addition of 50 μL of 1 M HCl/0.4 M acetate and 800 μL of ethyl acetate. After centrifugation (10000 g, 5 mins), an aliquot of 600 μL of the upper phase was counted for radioactivity in 3 mL of liquid scintillation cocktail. MC1568 was tested at a starting concentration of 40 μM, and active substances were diluted further. NaB, VPA, TSA, SAHA, 85TPX, HC-toxin, and tubacin were used as the reference compounds, and blank solvents were used as negative controls. |
