Abstract: The present invention relates to a novel class of substituted spirocyclic compounds, represented by the following structural Formula: I Wherein A, B and D are independently selected from CR12, NR1a, C(O) and O; E is selected from a bond, CR12, NR1a, C(O) and O; wherein at least one of A, B, D or E is CR12; and provided that when A is O, then E is not O; G is CR12; R is selected from NH2 and OH; These compounds can inhibit histone deacetylase and are suitable for use in selectively inducing termin differentiation, and arresting cell growth and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells. Thus, the compounds of the present invention are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells.

Abstract: The present invention relates to a novel class of benzothiophene amide derivatives. The hydroxamic acid compounds can be used to treat cancer. The benzothiophene amide compounds can also inhibit histone deacetylase and are suitable for use in selectively inducing terminal differentiation, and arresting cell growth and/or apoptosis of neoplastic cells, thereby inhibiting proliferation of such cells. Thus, the compounds of the present invention are useful in treating a patient having a tumor characterized by proliferation of neoplastic cells.
