How to use

In Vitro:

TAS4464 selectively inhibits NAE relative to the other E1s UAE and SAE. TAS4464 treatment inhibits cullin neddylation and subsequently induces the accumulation of CRL substrates such as CDT1, p27, and phosphorylated IkBa in human cancer cell lines. Cytotoxicity profiling reveals that TAS4464 is highly potent with widespread antiproliferative activity not only for cancer cell lines, but also patient-derived tumor cells.

In Vivo:

TAS4464 shows prolonged target inhibition in human tumor xenograft mouse models; weekly or twice a week TAS4464 administration led to prominent antitumor activity in multiple human tumor xenograft mouse models including both hematologic and solid tumors without marked weight loss.
