Abstract

APO866 inhibits nicotinamide phosphoribosyltransferase (NMPRTase), a key enzyme involved in nicotinamide adenine dinucleotide (NAD) biosynthesis from the natural precursor nicotinamide. Intracellular NAD is essential for cell survival, and NAD depletion resulting from APO866 treatment elicits tumor cell death. Here, we determine the in vitro and in vivo sensitivities of hematologic cancer cells to APO866 using a panel of cell lines (n = 45) and primary cells (n = 32). Most cancer cells (acute myeloid leukemia [AML], acute lymphoblastic leukemia [ALL], mantle cell lymphoma [MCL], chronic lymphocytic leukemia [CLL], and T-cell lymphoma), but not normal hematopoietic progenitor cells, were sensitive to low concentrations of APO866 as measured in cytotoxicity and clonogenic assays. Treatment with APO866 decreased intracellular NAD and adenosine triphosphate (ATP) at 24 hours and 48 to72 hours, respectively. The NAD depletion led to cell death. At 96 hours, APO866-mediated cell death occurred in a caspase-independent mode, and was associated with mitochondrial dysfunction and autophagy. Further, in vivo administration of APO866 as a single agent prevented and abrogated tumor growth in animal models of human AML, lymphoblastic lymphoma, and leukemia without significant toxicity to the animals. The results support the potential of APO866 for treating hematologic malignancies.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
