DI-1859 is a DCN1 and cullin 3 inhibitor with a K_i of <1 nM against human DCN1. DI-1859 forms a covalent bond with Cys115 of DCN1, cleaves its dimethylamino group, disrupts the DCN1-UBC12 interaction, and selectively inhibits the neddylation modification of cullin 3 relative to other cullins. DI-1859 inactivates CRL3, promotes the accumulation of NRF2 and SLC7A11, upregulates the expression of HO-1 and NQO1, reduces reactive oxygen species (ROS) levels, enhances insulin signaling, promotes insulin secretion, activates RhoA, regulates the phosphorylation of AKT, without completely blocking the neddylation modification of cullin 3 or restoring the expression of IRS-1. DI-1859 can be used in the research of Acetaminophen (HY-66005)-induced hepatotoxicity, hyperglycemia, metabolic dysfunction-associated steatotic liver disease, insulin resistance, breast cancer and lung cancer.

Help & FAQs

How should lyophilized recombinant proteins be reconstituted and stored?

1. Before opening the cap, centrifuge the vial at 13000 rpm for 20-30 seconds. This step will ensure that any lyophilized powder that may have adhered to the cap or walls is collected at the bottom of the vial, minimizing the risk of product loss.
