AT791 是一种有效的口服生物利用TLR7和TLR9抑制剂。AT791 抑制多种人类和小鼠细胞类型的 TLR7 和 TLR9 信号传导,并在体外抑制 DNA-TLR9 相互作用。
生物活性 | AT791 is a potent and orally bioavailableTLR7andTLR9inhibitor. AT791 inhibitsTLR7and 9 signaling in a variety of human and mouse cell types and inhibits DNA-TLR9 interaction in vitro[1]. |
IC50& Target[1] | TLR7 3.33 μM (IC50) | TLR9 0.04 μM (IC50) |

体外研究 (In Vitro) | AT791 potently suppresses DNA stimulation of HEK:TLR9 cells, with IC50of 0.04 μM and is significantly less effective at suppressing R848 stimulation of HEK:TLR7 cells (IC50= 3.33 μM)[1]. AT7916 suppresses TLR9-DNA interaction in vitro, with an IC50in the 1 to10 μM range[1]. AT791 and E6446 are typical of “lysosomotropic”compounds in that they are lipophilic and contain weak base amines. At neutral pH, such compounds are nonpolar and can penetrate lipid membranes, but within low pH vesicles they become protonated and are trapped (de Duve et al., 1974). Capillary electrophoresis showed that AT791 has pKas of 7.9 and 6.1, and E6446 has pKas of 8.6 and 6.5, indicating they would be more highly protonated in endolysosomal compartments compared with cytoplasm[1].
