  • Publication number: 20230033291
    Abstract: Excessive deposition of extracellular matrix is a hallmark of Idiopathic pulmonary fibrosis (IPF), it is advantageous to target the cells and the mechanisms associated with this process. By targeting myofibroblasts (specialized contractile fibroblasts) that are key for the development of IPF with drugs conjugated with fibroblast activation protein (FAP). this technology helps minimize the production of extracellular matrix in the lungs and provides a new treatment option for patients diagnosed with IPF.

  • Publication number: 20230018687
    Abstract: The present disclosure generally relates to methods of treating hemolytic diseases such as sickle cell anemia using kinase inhibitors, for example, compounds that inhibit the spleen tyrosine kinase (SYK). In some embodiments a method is presented to prevent thrombosis in blood vessels of patients with a hemolytic disease comprising the step of: administrating to a patient having at least one hemolytic disease a therapeutically effective amount of at least one SYK inhibitor. In some embodiments the method includes repeatedly administering the SYK kinase inhibitor to a patient.

  • Publication number: 20220331434
    Abstract: Compounds, pharmaceutical compositions and methods are provided for reprogramming M2-like macrophages to M1-like macrophages, which reverses the antifibrotic to profibrotic shift observed during the course of fibrotic diseases and certain cancers. The compounds comprise an immune modulator that targets a pattern recognition receptor of a cell and are specific to the cells of interest through the incorporation of a targeting moiety (e.g., folate or a functional fragment or analog thereof). Releasable and/or non-releasable linkers can be included and engineered to facilitate the optimal delivery of the immune modulator. The compounds and compositions can be employed in one or more methods of treatment for fibrotic diseases and/or cancers.
