Bz 423 is primarily studied for its potential therapeutic applications in autoimmune diseases and cancer. It functions by selectively inducing apoptosis in pathogenic lymphocytes, making it a promising candidate for treating conditions like lupus and rheumatoid arthritis. In cancer research, Bz 423 has shown efficacy in targeting and killing cancer cells while sparing healthy cells, particularly in hematologic malignancies. Its ability to modulate the mitochondrial pathway and induce cell death has garnered significant interest in preclinical studies. Researchers are also exploring its use in combination therapies to enhance its effectiveness and reduce drug resistance.
