Interferon inducers are generally most effective as antiviral agents when used prophylactically. One possible explanation for this is that animals develop a state of hyporeactivity during the course of a virus infection. Such a progressive loss of capacity to produce interferon was observed with a representative group of interferon-inducing agents (polyinosinic-cytidylic acid, Tilorone hydrochloride, New-castle disease virus, or a strain of encephalomyocarditis virus) during the course of a model picornavirus infection in mice.
干扰素诱导剂在预防性使用时通常作为抗病毒剂最为有效。对此的一种可能解释是,动物在病毒感染过程中会出现反应性降低的状态。在小鼠的一种典型小核糖核酸病毒感染过程中,用一组具有代表性的干扰素诱导剂(聚肌苷酸 - 胞苷酸、盐酸泰洛龙、新城疫病毒或脑心肌炎病毒株)观察到了这种产生干扰素能力的逐渐丧失。
