Chitohexaose hexahydrochloride is a chitosan oligosaccharide with anti-inflammatory effect. Chitohexaose hexahydrochloride binds to the active sites of TLR4 and inhibits LPS induced inflammation.

Sparstolonin B acts as a selective TLR2 and TLR4 antagonist and selectively blocks TLR2- and TLR4-mediated inflammatory signaling. Sparstolonin B has anti-HIV and anticancer activities.

Pam3CSK4-Biotin is biotinylated Pam3CSK4. Pam3CSK4-Biotin is a Toll-like receptor 1/2 (TLR1/2) agonist.

Pam3CSK4 is a toll-like receptor 1/2 (TLR1/2) agonist with an EC50 of 0.47 ng/mL for human TLR1/2.

CU-T12-9 is a specific TLR1/2 agonist with EC50 of 52.9 nM in HEK-Blue hTLR2 SEAP assay. CU-T12-9 activates both the innate and the adaptive immune systems. CU-T12-9 selectively activates the TLR1/2 heterodimer, not TLR2/6. CU-T12-9 signals through NF-κB and invokes an elevation of the downstream effectors TNF-α, IL-10, and iNOS.

DSR-6434 is a potent and selective Toll-like receptor 7 (TLR7) agonist, with EC50s of 7.2 nM and 4.6 nM for human and mice TLR7, respectively. DSR-6434 has a strong antitumor effect.

TLR7 and 8 modulator 31 is a potent, orally active, dual TLR7 and 8 agonist with LEC values of 0.15 and 0.16 uM, respectively.

Isatoribine is a selective agonist of TLR7

Chloroquine diphosphate is an antimalarial drug and autophagy/lysosome inhibitor; inhibits Toll-like receptor (TLR) signalling in plasmacytoid dendritic cells (pDCs).
