Cas no 84088-42-6 (Roquinimex)

Roquinimex is a synthetic immunomodulatory compound with potential applications in the treatment of autoimmune diseases and certain cancers. Its mechanism of action involves the modulation of cytokine production, particularly suppressing pro-inflammatory cytokines such as TNF-α and IL-1β, while enhancing anti-inflammatory responses. Roquinimex has demonstrated efficacy in preclinical studies for its ability to inhibit excessive immune activation, making it a candidate for conditions like rheumatoid arthritis and multiple sclerosis. Its well-characterized pharmacokinetic profile and oral bioavailability further support its therapeutic potential. Research continues to explore its broader immunoregulatory effects and clinical applicability in oncology and chronic inflammatory disorders.
