Patent number: 12453731Abstract: 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.Type: GrantFiled: March 22, 2019Date of Patent: October 28, 2025Assignee: China Pharmaceutical UniversityInventors: Qidong You, Xiaoke Guo, Weilin Chen, Dongdong Li, Jing Gu, Jun Xu, Xin Chen, Zhengyu Jiang, Xiaoli Xu

Patent number: 12383535Abstract: 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 H2O2-responsive thiazolidinone moiety, a novel ROS-responsive antioxidant prodrug pro2 is synthesized. The H2O2 activated 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 H2O2-responsive prodrug suitable for oral administration, and is expected to be used clinically by virtue of the characteristics of druggability and high targeting ability.Type: GrantFiled: November 16, 2020Date of Patent: August 12, 2025Assignee: CHINA PHARMACEUTICAL UNIVERSITYInventors: Qidong You, Zhengyu Jiang, Mengchen Lu, Xian Zhang, Jing Zhao, Xiaoke Guo, Xiaoli Xu, Lei Wang
