Description
Gardiquimod is a imidazoquinoline compound. Gardiquimod is a Toll-like receptor (TLR)-7 agonist and, like other TLR7 agonists, such as Imiquimod (R837), is an immune response modifier with potent antitumor activity. Gardiquimod has been shown to activate antigen-presenting cells, including dendritic cells (DC) and promote activation of T and natural killer (NK) cells making it a good vaccine adjuvant candidate.
A recent study suggests that Gardiquimod may serve as a vaccine adjuvant to potentiate the efficiency of DC-based tumor immunotherapy. In another study, a tuberculosis vaccine formulated with Gardiquimod was found to protect mice against Mycobacterium tuberculosis when administred intradermally. Furthermore, Velasquez et al. have reported the potential use of Gardiquimod as a mucosal adjuvant for viruslike particles-based vaccines.
