DI-591 是一种有效，高亲和力和细胞渗透性的 DCN1-UBC12 相互作用的抑制剂。DI-591 分别以 K_i 值为 12 nM 和 10.4 nM 与 DCN1 和 DCN2 结合，并且几乎不与 DCN3，DCN4 和 DCN5 蛋白结合。DI-591 选择性抑制 cullin 3 的二烯化，但对其他 cullin 家族成员的二烯化没有影响或影响很小。

DI-591 is a potent, high-affinity and cell-permeable inhibitor of the DCN1-UBC12 interaction. DI-591 binds to DCN1 and DCN2 with K i values of 12?nM and 10.4 nM, respectively and has no appreciable binding to DCN3, DCN4, and DCN5 proteins. DI-591 selectively inhibits neddylation of cullin 3 but has no or minimal effect on neddylation of other cullin family members.

Solid

DCN1-UBC12

DI-591 (Compound 44) binds to DCN1 and DCN2 with Ki values of 12?nM and 10.4 nM, respectively and has no appreciable binding to DCN3, DCN4, and DCN5 proteins. Hence, DI-591 displays a very-high binding affinity to recombinant human DCN1 and DCN2 proteins and >1000-fold selectivity over recombinant human DCN3-5 proteins.
DI-591 (Compound 44; 0-10 μM; 1 hour; KYSE70 cells) binds to both cellular DCN1 and DCN2 proteins and disrupts the association of cellular DCN1 and UBC12 proteins.
DI-591 (Compound 44; 10 μM; 24 hours; THLE2 cells) treatment robustly increases the mRNA levels of NQO1 and HO1, leading to upregulation of HO1 protein in the cells. Significantly, DI-591 has no effect on the mRNA level of NRF2.
The selective inhibition of neddylation of cullin 3 by DI-591 leads to accumulation NRF2 protein and its transcriptional activation.
