MS67 is primarily utilized in the field of medical research, particularly in the study of cancer therapies. It functions as a selective inhibitor of the protein kinase C-theta (PKC-θ), which plays a crucial role in T-cell activation and survival. By inhibiting PKC-θ, MS67 helps researchers understand the signaling pathways involved in immune responses and the development of autoimmune diseases. This compound is also investigated for its potential to enhance the efficacy of immunotherapies by modulating T-cell activity, offering a promising avenue for treating various cancers. Additionally, MS67 is used in preclinical studies to explore its effects on inflammatory conditions, providing insights into the development of novel anti-inflammatory drugs.
