A family of 1,4-benzodiazepine-2,5-diones (BZDs) has been synthesized and evaluated against transformed B- and T-cells for lymphotoxic members. A large aromatic group on the C3 position is critical for cytotoxicity. When the C3 moiety contains an electron-rich heterocycle, the resulting BZDs have sub-micromolar potency and are selective for T-cells. Cell death is consistent with apoptosis and does not result from inhibition of the mitochondrial F(o)F1-ATPase, which is the molecular target of recently reported cytotoxic 1,4-benzodiazepines. Collectively, these studies begin to characterize some of the structural elements required for the activity of a novel family of T-cell-selective lymphotoxic agents.

D013329 Structure-Activity Relationship The relationship between the chemical structure of a compound and its biological or pharmacological activity. Compounds are often classed together because they have structural characteristics in common including shape, size, stereochemical arrangement, and distribution of functional groups.

D013601 T-Lymphocytes Lymphocytes responsible for cell-mediated immunity. Two types have been identified - cytotoxic (T-LYMPHOCYTES, CYTOTOXIC) and helper T-lymphocytes (T-LYMPHOCYTES, HELPER-INDUCER). They are formed when lymphocytes circulate through the THYMUS GLAND and differentiate to thymocytes. When exposed to an antigen, they divide rapidly and produce large numbers of new T cells sensitized to that antigen.
