Application

Resiquimod has been used in the stimulation of bone marrow-derived dendritic cells (BMDCs) stimulation( and B cells. It has also been used as a ligand for toll-like receptors (TLR7) in malignant melanoma cell line B16F10.
Resiquimod may be used in immunological and cancer-related cell signaling studies.

Biochem/physiol Actions

Resiquimod (R-848) is a potent synthetic agonist of TLR7/TLR8 that possesses antiviral and antitumoral activities.
Resiquimod belongs to the class of imidazoquinolinamines compounds with immunomodulatory effects. Resiquimod increases the levels of cytokines such as TNF-α, IL-6 and IFN-α.
Resiquimod is 314.4 Da molecule which elicits immune function during visceral infection with L. infantum Sp. It mediates the trafficking of granulocytes, macrophages, leukocytes and dendritic cells. It is a recommended topical drug for treating skin tumors like actinic keratosis (AK) and superficial basal cell carcinoma.
Resiquimod is an agonist of toll-like receptor 7 and 8 (TLR- and TLR-8).

Toll-like receptors (TLRs) are pattern-recognition receptors related to the Drosophila Toll protein. TLR activation alerts the immune system to microbial products and initiates innate and adaptive immune responses.
