GSK1795091 (CRX-601), an immunologic stimulator, is a synthetic TLR4 agonist. Antitumor activity. GSK1795091 can be used as a vaccine adjuvant to enhance both mucosal and systemic immunity to influenza virus vaccines.

Tri(TLR4-IN-C34-PEG2-amide-PEG1)-amide-C3-COOH is a linker that incorporates TLR4 inhibitor TLR4-IN-C34. TLR4-IN-C34 inhibits TLR4 in enterocytes and macrophages, and reduces systemic inflammation in mouse models of endotoxemia and necrotizing enterocolitis.

CU CPT 4a is a potent inhibitor of the toll-like receptor 3 (TLR3)/double-stranded RNA (dsRNA) complex. CU CPT 4a shows dose-dependent inhibitory effects blocking Poly (I:C)-induced TLR3 activation with an IC50 of 3.44 µM.

Afimetoran is a toll-like receptor antagonist, which can be used in the research of inflammatory and autoimmune diseases.

Guretolimod is a Toll-like receptor 7 (TLR7) agonist.

RS 09 TFA is a TLR4 agonist. RS 09 TFA promotes NF-κB nuclear translocation and induces inflammatory cytokine secretion in RAW264.7 macrophages in vitro. RS 09 TFA acts as an adjuvant in vivo; RS 09 TFA enhances X-15 specific antibody serum concentrations, when administered with X-15-KLH in mice.

Kdo2-Lipid A ammonium is a chemically defined lipopolysaccharide (LPS) with endotoxin activity equal to LPS. Kdo2-Lipid A ammonium is highly selective for TLR4. Kdo2-Lipid A ammonium stimulates the release of both TNF and PGE2.

Pepinh-TRIF (TFA) is a 30 aa peptide that blocks TIR-domain-containing adapter-inducing interferon-β (TRIF) signaling by interfering with TLR-TRIF interaction.

Stepharine, an natural alkaloid, directly interactes with TLR4 and binds to the TLR4/MD2 complex (TLR4 inhibitor). Stepharine possesses anti-aging, anti-viral and anti-hypertensive effects.

CAY10614 is a potent TLR4 antagonist. CAY10614 inhibits the lipid A-induced activation of TLR4, with an IC50 of 1.675 μM. CAY10614 can improve survival of mice in lethal endotoxin shock model.

AXC-715 hydrochloride is a TLR7/TLR8 dual agonist, extracted from patent WO2020168017 A1.

FSL-1 TFA, a bacterial-derived toll-like receptor 2/6 (TLR2/6) agonist, enhances resistance to experimental HSV-2 infection. FSL-1 TFA induces MMP-9 production through TLR2 and NF-κB/AP-1 signaling pathways in monocytic THP-1 cells.

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
