TLR7 agonist 22

TLR7 agonist22 (Compound 11a) is a selective TLR7 agonist with an IC50 value of 25.86 μM. It inhibits the secretion of cell HBsAg and effectively activates TLR7, inducing the release of TLR7-regulated cytokines IL-12, TNF-α, and IFN-α in human PBMC cells. TLR7 agonist22 shows promise for developing novel immunomodulatory drugs in HBV research.
