TLR7 agonist 17 (compound 20) functions as a highly effective TLR7 agonist, exhibiting EC 50 values of 12 nM for hTLR7 and 17 nM for mTLR7. Additionally, this compound has demonstrated anticancer activity [1].
D18 is an immune modulator that acts as a dual agonist for TLR7 8 (with EC50 values of 24 nM for hTLR7 and 10 nM for hTLR8, respectively). It enhances the expression of PD-L1 through epigenetic regulation, thereby increasing the sensitivity of tumors to PD-1 PD-L1 blockade. Additionally, D18 functions as a cytotoxin for ADC synthesis, specifically for the ADC HE-S2 [1].
GSK2245035 is a highly selective intranasal TLR7 agonist with preferential Type-1 interferon (IFN)-stimulating properties (pEC50s: 9.3 and 6.5 for IFNα and TFNα). It effectively suppresses allergen-induced Th2 cytokine production in human peripheral blood
3M-011, a potent dual toll-like receptor TLR7 8 agonist and cytokine inducer, serves as a powerful adjuvant to radiotherapy, eliciting significant local and systemic immune responses. Additionally, it effectively inhibits H3N2 influenza viral replication in the nasal cavity and exhibits strong antitumor activity[1][2][3].
AXC-715 hydrochloride is a TLR7/TLR8 dual agonist, can be used for synthesis of antibody-adjuvant immunoconjugates, comprising an antibody construct that binds programmed death-ligand 1 (PD-L1) linked to one or more adjuvants.
