General description

CL264 is a hydrophilic molecule. CL264,an adenine analog, is a potent and selective toll-like receptor 7 (TLR7) agonist with no TLR8-stimulating potency. This bioactive small molecule belongs to the category of 9-benzyl-8-hydroxyadenine derivatives. It contains a glycine molecule attached to the benzyl group. Studies show that CL264 is capable of activating NF-κB and stimulating the secretion of IFN-α in cells that express TLR7. CL264 is commonly used at a concentration range from 2 ng/mL to 10 μg/mL for stimulating cells in cultures.

A well-controlled innate immune response is characterized by a rapid yet self-limiting inflammatory response. Although much is known about the range of inflammatory stimuli capable of triggering an innate immune response, the mechanisms which govern the degree of inflammation induced

TLR7 ligation in plasmacytoid dendritic cells is promising for the treatment of cancer, allergy, and infectious diseases; however, high doses of ligands are required. We hypothesized that the combination of structurally different TLR7 ligands exponentiates the resulting immune response. CAL-1

The detection of microorganisms and danger signals by pattern recognition receptors on dendritic cells (DCs) and the consequent formation of inflammasomes are pivotal for initiating protective immune responses. Although the activation of inflammasomes leading to secretion of the cytokine IL-1β
