  • Patent number: 5858694
    Abstract: This invention provides a method to identify compounds potentially useful for the treatment of neoplasia in mammals. The phosphodiesterase inhibitory activity of a compound is determined along with COX inhibitory activity. Growth inhibitory and apoptosis inducing effects on cultured tumor cells are also determined. Compounds that exhibit phosphodiesterase inhibiton, growth inhibition and apoptosis induction, but not substantial prostaglandin inhibitory activity, are desirable for the treatment of neoplasia.
