An interferon (IFN) inducer and immunomodulator, CL246,738 [3,6-bis(2-piperidinoethoxy)acridine trihydrochloride], protected mice from lethal infection with Semliki Forest (SFV) and Banzi (BZV) viruses. A single oral dose of CL246,738 (5-150 mg/kg) administered 24 h before intraperitoneal challenge with SFV or BZV fully protected mice from lethal infection. Dose-dependent levels of circulating IFN peaked at 24 h in the serum and peritoneal fluid of CL246,738-treated mice. The circulating IFN of CL246,738-treated mice consisted of IFN-alpha and was produced by spleen cells. Peritoneal exudate cells (PEC) obtained from CL246,738-treated mice produced IFN-beta. Treatment in vivo with anti-IFN-alpha/beta and anti-IFN-beta reversed the protective effect of CL246,738 against lethal SFV encephalitis.
一种干扰素(IFN)诱导剂和免疫调节剂CL246,738[3,6 - 双(2 - 哌啶基乙氧基)吖啶三盐酸盐]可保护小鼠免受塞姆利基森林病毒(SFV)和班齐病毒(BZV)的致死性感染。在腹腔注射SFV或BZV前24小时口服单次剂量的CL246,738(5 - 150毫克/千克)可完全保护小鼠免受致死性感染。在接受CL246,738治疗的小鼠的血清和腹腔液中,循环IFN的剂量依赖性水平在24小时达到峰值。接受CL246,738治疗的小鼠的循环IFN由IFN - α组成,由脾细胞产生。从接受CL246,738治疗的小鼠获得的腹腔渗出细胞(PEC)产生IFN - β。用抗IFN - α/β和抗IFN - β进行体内治疗可逆转CL246,738对致死性SFV脑炎的保护作用。
