The present disclosure discloses a WDR5 protein-protein interaction inhibitor, including a compound having a structure represented by general formula (I). Experiments show that the inhibitor acts on a WDR5 protein and an interacting protein thereof including, but not limited to, MLL, selectively inhibits the proliferation of leukemia cells, and inhibits the methylation of H3K4 and the expression of downstream Hox/Meis-1 gene at the cellular level. The present disclosure also discloses a method for preparing the inhibitor and use thereof in the preparation of a drug for treating acute leukemia and other related diseases.

Aniline-based WDR5 protein-protein interaction inhibitor, and preparation method and use thereof

The present application relates to a hydrogen peroxide-responsive Keap1-Nrf2 PPI inhibitor prodrug, and a preparation method therefor. The hydrogen peroxide-responsive Keap1-Nrf2 PPI inhibitor prodrug pro2 has a chemical structure as shown below. By modifying a key carboxyl pharmacophore in a Keap1-Nrf2 inhibitor with a HO-responsive thiazolidinone moiety, a novel ROS-responsive antioxidant prodrug pro2 is synthesized. The HOactivated prodrug pro2 can simultaneously achieve targeted activation of Nrf2 and enhancement of therapeutic efficacy in the body. The prodrug is based on the concept of ROS activation-ROS clearance therapy, is the first example of a HO-responsive prodrug suitable for oral administration, and is expected to be used clinically by virtue of the characteristics of druggability and high targeting ability.
