  • Publication number: 20230226092
    Abstract: Disclosed is NUC-1031 (gemcitabine-[phenyl-benzoxy-L-alaninyl)]-phosphate), a ProTide derivative of gemcitabine, for use in targeting cancer stem cells. This targeting of cancer stem cells may be employed in the prevention or treatment of cancer. NUC-1031 may be used in treatment of relapsed or refractory cancer in a human patient. Without wishing to be bound by any hypothesis, it is believed that the ability of NUC-1031 to target cancer stem cells contributes to its utility in the treatment of relapsed or refractory cancers.

  • Patent number: 11629164
    Abstract: This invention relates to a prodrug of the monophosphate nucleotide of the well-known oncology drug gemcitabine. Specifically, it relates to gemcitabine-[phenyl-benzoxy-L-alaninyl)]-phosphate when present as a single phosphate diastereoisomer and, in particular, it relates to the (S)-phosphate diastereoisomer which offers a remarkable and unexpected increase in solubility relative to the (R)-diastereoisomer. The (S)-phosphate epimer is also preferentially taken up into cyclodextrin solutions over the (R)-diastereoisomer.
