Summary for Patent: 7,767,689
Title:Carboline derivatives useful in the treatment of cancer
Abstract: In accordance with the present invention, compounds that inhibit the expression of VEGF post-transcriptionally have been identified, and methods for their use provided. In one aspect of the invention, compounds useful in the inhibition of VEGF production, in the treatment of solid tumor cancer, and in reducing plasma and/or tumor VEGF levels, are provided. In another aspect of the invention, methods are provided for the inhibition of VEGF production, the treatment of cancer, and the reduction of plasma and/or tumor VEGF levels, using the compounds of the invention.
