A new synthetic compound, 6-hydroxy-2-tosylisoquinolin-1(2H)-one (2-OH), was selected for immunopharmacological activity tests. The effects of 2-OH on human peripheral blood mononuclear cell (PBMC) proliferation were determined by tritiated thymidine uptake. Compared to phytohemagglutinin (PHA; 5 μg/mL) stimulation, 2-OH significantly enhanced PBMC proliferation in a dose-dependent manner. The 50% enhancement activity (EC50) for 2-OH was 4.4±0.1 μM. In addition, effects of 2-OH on interleukin-2 (IL-2) and interferon-γ (IFN-γ) production in PBMC were determined by enzyme immunoassay. Results demonstrated that 2-OH stimulated IL-2 and IFN-γ production in PBMC. Data from reverse transcription-polymerase chain reaction (RT-PCR) and real-time PCR indicated that IL-2 and IFN-γ mRNA expression in PBMC could be induced by 2-OH. Therefore, 2-OH enhanced IL-2 and IFN-γ production in PBMC by modulation their gene expression. We suggest that 2-OH may be an immunomodulatory agent.
选择一种新的合成化合物6-羟基-2-甲苯磺酰异喹啉-1(2H)-酮(2-OH)进行免疫药理活性测试。通过氚化胸苷摄取测定 2-OH 对人外周血单核细胞 (PBMC) 增殖的影响。与植物血凝素(PHA;5 μg/mL)刺激相比,2-OH 以剂量依赖性方式显着增强 PBMC 增殖。 2-OH 的 50% 增强活性 (EC50) 为 4.4±0.1 μM。此外,通过酶免疫测定法测定了 2-OH 对 PBMC 中白细胞介素 2 (IL-2) 和干扰素 γ (IFN-γ) 产生的影响。结果表明,2-OH 刺激 PBMC 中 IL-2 和 IFN-γ 的产生。逆转录聚合酶链反应(RT-PCR)和实时PCR的数据表明,2-OH可以诱导PBMC中IL-2和IFN-γ mRNA的表达。因此,2-OH 通过调节基因表达来增强 PBMC 中 IL-2 和 IFN-γ 的产生。我们认为 2-OH 可能是一种免疫调节剂。
