Used primarily as an immune response modifier, this compound exhibits potent antiviral and antitumor activity. It functions by activating the innate immune system through stimulation of Toll-like receptor 7 (TLR7) and TLR8, leading to the production of cytokines such as interferon-alpha and other pro-inflammatory mediators. Due to this mechanism, it is employed in topical formulations for the treatment of external genital warts caused by human papillomavirus (HPV). Its ability to induce local immune activation makes it effective in clearing warts and reducing recurrence rates. Additionally, it has been investigated for use in other dermatological conditions and in cancer immunotherapy due to its capacity to enhance immune surveillance.
