  • Patent number: 11773057
    Abstract: Disclosed in the present invention are a naphthalenesulfonamide compound, a preparation method, and an application. The naphthalenesulfonamide compound provided by the present invention can interfere with Keap1-Nrf2 binding and activate Nrf2 to relieve inflammatory damage and improve an inflammatory microenvironment, has a potential anti-inflammatory activity, and can be used for preparing an anti-inflammatory drug for inflammatory damage of various inflammation-related diseases, including chronic obstructive pulmonary disease (COPD), Alzheimer's disease, Parkinson's disease, atherosclerosis, chronic kidney disease (CKD), diabetes, intestinal Inflammations, rheumatoid arthritis, etc.

  • Publication number: 20220401419
    Abstract: 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.

  • Patent number: 11504385
    Abstract: It discloses a proteolysis targeting chimeric molecule, a preparation method and an application thereof. The proteolysis targeting chimeric molecule provided by the disclosure can inhibit the expression of BCR-ABL and/or CRBN protein in BCR-ABL and/or CRBN positive leukemia K562 cells to varying degrees, and thus can be used to prepare drugs for treating BCR-ABL and/or CRBN positive leukemia, wherein the proteolysis targeting chimeric molecule with n=3 has excellent photo-isomerization activity, and can be used in preparation of the reagents or drugs for light-regulated degradation of BCR-ABL and/or CRBN protein. The disclosure also provides a method for synthesizing the series of proteolysis targeting chimeric molecules.
