Used primarily in the pharmaceutical industry as an active pharmaceutical ingredient (API) in immunomodulatory drugs. It functions by modulating the immune system, inhibiting the production of pro-inflammatory cytokines, and promoting degradation of specific proteins involved in cell proliferation. Commonly applied in the treatment of multiple myeloma and other hematological cancers due to its ability to interfere with tumor cell growth and angiogenesis. Also investigated for use in inflammatory and autoimmune conditions owing to its immunosuppressive and anti-inflammatory properties. Its mechanism includes binding to cereblon, a component of the E3 ubiquitin ligase complex, leading to targeted degradation of disease-related proteins.
