Background
Trapoxin A is a cyclotetrapeptide histone deacetylase (HDAC) inhibitor. It inhibits HDAC activity in a concentration-dependent and irreversible manner. Trapoxin A inhibits proliferation of NIH3T3 cells transformed by the oncogene v-sis (sis/NIH3T3; IC50 = ~200 ng/ml) and has detransformation activity, flattening sis/NIH3T3 cells when used at a concentration of 1 ng/ml. It also halts the cell cycle at the G2 phase in 3Y1 fibroblasts when used at a concentration of 10 nM and inhibits growth of TR303 cells resistant to trichostatin A at a concentration of 50 ng/ml.
