Near-Total Polyamine Depletion In Tumors
Attempts to retard tumor growth by depleting intracellularpolyamines aimed, with partial efficacy, at blocking enzymes inpolyamine biosynthesis. Invention discloses analogues that bindDNA, but do not function as natural polyamines, and cause almosttotal depletion of intracellular stores of these molecules. Thesynthetic polyamines also sensitize tumors to conventionalchemotherapeutics.

Screening For Apoptosis-Causing Compounds
Certain cancers arise from loss of ability to invoke programmed celldeath. One pathway for detecting malignant transformation andinducing apoptosis involves p53 gene product. Invention describesdiagnostic assays based on this tumor suppressor's interactions withXeroderma pigmentum proteins, and triggering of p53-mediatedapoptosis.
