CU-CPT17e shows strong NF-κB activation in TLR3, TLR8 and TLR9 HEK293 cells with EC50 values of 4.80±0.73, 13.5±0.58 and 5.66±0.17 μM, respectively. CU-CPT17e significantly improves the activity with 13.9±0.9 fold of NF-κB activation and an EC50 value of 4.8±0.7 μM. CU-CPT17e inhibits the proliferation of HeLa cancer cells by triggering apoptosis and arresting the cell cycle at the S phase. The induction of apoptosis by CU-CPT17e in HeLa cells is investigated. HeLa cells are cultured with increasing concentrations of CU-CPT17e or poly I:C or blank control (DMSO) for 24 h. Treatment with CU-CPT17e for 24 h at different concentrations (10 to 40 μM) results in an elevation of apoptotic cell population ranging from 10% to 17%, which is more effective than poly I:C at 5 μg/mL. These results suggest that the antiproliferative activity of CU-CPT17e against HeLa cells might result from its ability to directly induce apoptosis[1].

CU-CPD107 is a TLR8-specific small molecule with unique synergistic agonist activities in the presence of ssRNA, but inactive without the aid of ssRNA.CU-CPD107 significantly inhibited of R848-induced signaling in HEK-Blue hTLR8 cells with an IC50 of 13.7 uM.CU-CPD107 only inhibited synthesized small-molecule agonist-induced TLR8 signaling without affecting other TLRs.CU-CPD107 synergistically increased IFN-β, TNF-α, IL-1β, IL-6, and IL-8 mRNA expression levels in the presence of 5 μg/ml ssRNA40 in HEK-Blue hTLR8 cells, whereas CU-CPD107 alone did not. CU-CPD107 only activated TLR8-mediated signaling in the presence of ssRNA.CU-CPD107 showed no pure agonistic activity, addressing a major challenge that has existed for previous TLR7 and TLR8 agonists as vaccine adjuvants or antiviral drugs.
