DSR-6434

Research use only, not for human use.

DSR-6434 has a strong antitumor effect. 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 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.(In Vitro):To assess the specificity of DSR-6434 toward TLR7, an NF-κB-driven reporter assay is performed in HEK293 cells engineered to express either hTLR7, TLR8 or TLR9. In this assay, successful binding of DSR-6434 to the specific receptor leads to NF-κB activation. DSR-6434 is capable of stimulating reporter gene activity only in HEK293 cells expressing hTLR7 and not in HEK293 cells expressing the structurally similar hTLR8 or hTLR9.(In Vivo):In B6C3F1 mice, DSR-6434 (0.1-1 mg/kg; i.v.) significantly suppresses lung metastasis.

DSR-6434 treatment (Compound 20; 0.1-1 mg/kg; intravenous injection; biweekly; for 4 weeks; B6C3F1 mice) suppresses the lung metastasis significantly, 78% inhibition at 0.1 mg/kg dosing (with no tumor metastasis at the 1 mg/kg group). Animal Model:B6C3F1 mice injected with HM-1 ovarian cancer cells Dosage:0.1 mg/kg, 1 mg/kg Administration:Intravenous injection; biweekly; for 4 weeks Result:Suppressed the lung metastasis significantly, 78% inhibition was seen at 0.1 mg/kg dosing (with no tumor metastasis at the 1 mg/kg group).
