Description: Motolimod is a selective Toll-like receptor 8 (TLR8) agonist, with an EC50 of approximately 100 nM.
In Vivo: Monkeys receive a subcutaneous injection of Motolimod (1 or 10 mg/kg), and plasma is collected predose, 6, 12, 24, and 96 h post-injection. For the 10 mg/kg dose, mean plasma levels of IL-1β increase from baseline levels of 0.5 pg/mL, up to 9.12±2.7 ng/mL (p<0.05, t-test) at 6 h post-administration of Motolimod (10 mg/kg). Circulating levels of IL-18 also increase from a baseline of ~ 1 pg/mL to 68.7±4.4 pg/mL (p<0.05, t-test) at 6 h in response to the Motolimod (VTX-2337) treatment (10 mg/kg). Levels of IL-6 are monitored, as this mediator is induced in response to TLR8 activation, but the release is independent of NLRP3 inflammasome activation. In addition, plasma levels of IFNγ are assessed as a measure of NK cell activation in response to Motolimod treatment[2].
In Vitro: Among the TLRs tested (TLR2, 3, 4, 5, 7, 8, and 9), Motolimod (VTX-2337) selectively activates TLR8. Motolimod stimulates the production of both TNFα (EC50=140±30 nM based on 10 donors) and IL-12 (EC50=120±30 nM based on 10 donors) in PBMCs. The EC50 value for MIP-1β induction is 60 nM for Motolimod[1].

DC50032 CU-CPT17e 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].
