Imidazoquinoline compound

Gardiquimod is an imidazoquinoline compound developed and manufactured by InvivoGen. This imidazoquinoline compound is a guanosine derivative and agonist for TLR7. Gardiquimod™ is an effective adjuvant by activating dendritic cells (DCs) and B cells to induce cytokines optimal for Th1 cell immunity, and antibody production.

Gardiquimod™ VacciGrade™ is suitable for preclinical studies. It is prepared under strict aseptic conditions. It is guaranteed sterile and thoroughly tested for the presence of endotoxins.

Gardiquimod™ VacciGrade™ is for research use only, not for use in humans.

Gardiquimod™ is a imidazoquinoline compound developed and manufactured by InvivoGen.

Similarly to Imiquimod, Gardiquimod™ induces the activation of NF-κB in HEK293 cells expressing human or mouse TLR7.

In vitro models of vaccination indicate that Gardiquimod™ is a strong immunostimulant inducing cytokine production and the generation of dendritic cells [1].

Experimental models demonstrated that Gardiquimod™ can induce strong cellular responses and has potential as an adjuvant for cancer therapy [2, 3].

Furthermore, Gardiquimod™ can induce mucosal responses that are superior to R848 and comparable to those induced by the established mucosal adjuvant cholera toxin [4].
