  • Patent number: 10029023
    Abstract: The present invention provides targeted nanoplex molecules which carry multimodality imaging reporters together with target enzyme inhibitors such as siRNAs and target prodrug enzymes, that are useful for theranostic imaging of cells and diseases, including, for example, various cancers, and including metastatic prostate cancer. The nanoplex molecules of the present invention provide a platform technology toward many cancer subtypes and alternative therapeutic targets. Downregulation of specific pathways using targeted enzyme inhibitors further provides unique opportunities to target cancer cells selectively while sparing normal tissue. The nanoplex molecule platform described herein has the ability to deliver multiple siRNA enzyme inhibitors. Methods of diagnosis and treatment of various diseases are also included.

  • Patent number: 7888330
    Abstract: The present invention provides phosphoramidate derivatives of a furanosyluracil analog, FAU, that can effectively deliver FAU monophosphate, or a derivative thereof, intracellularly. FAU-Phosphoramidate diesters can bypass the first step of phosphorylation and be activated intracellularly so as to be converted to nucleoside monophosphates. This results in improved formation of nucleoside triphosphates, and higher incorporation into DNA. The compounds of the invention can be used to treat cancer.
    Type: Grant
