Verfahren zur Identifizierung von Verbindungen zur Hemmung von neoplastischen Veränderungen

摘要

There is disclosed a pharmaceutical composition for the treatment of neoplasia, comprising a pharmaceutically acceptable carrier and a compound selected by: determining the cyclooxyegenase (COX) inhibitory activity of the compound; determining the PDE inhibition activity of the compound wherein the PDE is characterized by: (a) cGMP specificity over cAMP; (b) positive cooperative kinetic behaviour in the presence of cGMP substrate; (c) submicromolar affinity for cGMP; and (d) insensitivity to incubation with purified cGMP-dependent protein kinase; and selecting the compound that has COX inhibitory activity lower than said PDE activity for treating neoplasia. Also provided by the invention is a method for selecting a compound the treatment of neoplasia, comprising determining the cyclooxygenase (COX) inhibitory activity of the compound; determining the PDE2 inhibition activity of the compound; and selecting the compound that has COX inhibitory activity lower than said PDE activity for treating neoplasia.
