Background

Gardiquimod is an agonist of human toll-like receptor 7 (TLR7) [1][2].

Toll-like receptors (TLRs) are a family of highly conserved pattern recognition receptors involved in innate immune responses to pathogen infection. TLR7 is highly expressed by plasmacytoid dendritic cells, and is also found on other leukocyte subpopulations. TLR7 and TLR8 recognize single-stranded RNA from viruses [4].

Gardiquimod is an agonist of human toll-like receptor 7 (TLR7), but not human TLR8, although it activates both porcine TLR7 and TLR8. In transfected 293T cells, Gardiquimod preferentially activated porcine TLR8 (pTLR8) [1]. Gardiquimod is a member of imidazoquinoline family. When codelivered intranasally with plant-derived Norwalk virus virus-like particles (NV VLPs), gardiquimod (GARD) induced NV VLP-specific serum IgG and IgG isotype responses and mucosal IgA responses in the gastrointestinal, respiratory, and reproductive tracts [3]. In macrophages and activated peripheral blood mononuclear cells (PBMCs) infected with X4, R5 or dual-tropic (R5/X4) strains of HIV-1, Gardiquimod inhibited HIV-1 reverse transcriptase and significantly reduced infection. Gardiquimod also induced interferon-alpha (IFN-a) transcription and sustained IFN-a protein secretion [4]. In BxPC-3 cells, Gardiquimod inhibited cell proliferation and migration, and induced apoptosis [5].

In C57BL/6 mice, Gardiquimod enhanced the ability of Treg cell to suppress the proliferation of Tresp cells. The CD4+CD25+Treg cells from mice that had received gardiquimod exhibited an increased inhibitory effect on anti-CD3/anti-CD28 mAb-coated bead-stimulated Tresp cells [2].

Working concentration: mg/ml;

Method for preparing DMSO master liquid: mg drug pre-dissolved in μL DMSO ( Master liquid concentration mg/mL, Please contact us first if the concentration exceeds the DMSO solubility of the batch of drug. )

Method for preparing in vivo formulation: Take μL DMSO master liquid, next addμL PEG300, mix and clarify, next addμL Tween 80, mix and clarify, next add μL ddH2O, mix and clarify.

Method for preparing in vivo formulation: Take μL DMSO master liquid, next add μL Corn oil, mix and clarify.

Note: 1. Please make sure the liquid is clear before adding the next solvent.
2. Be sure to add the solvent(s) in order. You must ensure that the solution obtained, in the previous addition, is a clear solution before proceeding to add the next solvent. Physical methods such as vortex, ultrasound or hot water bath can be used to aid dissolving.
3. All of the above co-solvents are available for purchase on the GlpBio website.
