Adilipoline™ (CL413) - TLR2 & TLR7 Bispecific Agonist

HEK-Blue™ hTLR2 cells  which stably express an NF-κB-inducible SEAP reporter gene and human TLR2 were incubated in HEK-Blue™ Detection (a SEAP detection growth medium) and stimulated with increasing concentrations of the agonists indicated in the graph.
After 24h incubation, the levels of NF-κB-induced SEAP were determined by reading the OD at 655 nm.

HEK-Blue™ hTLR7 cells, which stably express an NF-κB-inducible SEAP reporter gene and human TLR7 were incubated in HEK-Blue™ Detection (a SEAP detection growth medium) and stimulated with increasing concentrations of the agonists indicated in the graph.
After 24h incubation, the levels of NF-κB-induced SEAP were determined by reading the OD at 655 nm.

RAW-Blue™ cells, which stably express an NF-κB-inducible SEAP reporter gene, were stimulated with 0.6 µg/ml of InvivoGen’s multi-PRR ligands complexed with 0.1 µg/ml HSV-60 (synthetic dsDNA).
After 24h incubation, the levels of NF-κB-induced SEAP were determined using QUANTI-Blue™, a SEAP detection reagent.

(A) Tumor growth after CL413 or CL401 treatment. C57BL/6 mice were inoculated subcutaneously with 5x10e5 B16-F1 mouse melanoma cells. After seven days, Adilipoline™ (CL413), CL401 or vehicle were injected intratumorally (50 µg/mouse/50 µl) on days 5, 15 and 20. (B) Survival curves for untreated as well as CL413- or CL401-treated mice.

Each group contained 8 mice. Black arrows represent the days of injection. Tumor growth was monitored and measured with calipers after day 5 of grafting tumor cells into mice and then every 2 days thereafter. Tumor volume in mm3 was determined according to the formula V = W2 x L/2, where L = length (mm) and W = width (mm).
