RN-9893 in TRPV4 current inhibition rates (87.6 % and 83.2 % at 10 μM, against RN-9893′s 49.4 %). For the first time, these RN-9893 analogues were profiled in an mouse model, where intraperitoneal injections of or at 10 mg/kg notably mitigated symptoms of acute lung injury induced by lipopolysaccharide (LPS). These outcomes indicate that compounds and are promising candidates for acute lung injury treatment
RN-9893 是 Renovis Inc. 鉴定的一种 TRPV4 拮抗剂,表现出对 TRPV4 通道的显着抑制作用。这项研究涉及合成和评估三个系列的 RN-9893 类似物的 TRPV4 抑制功效。值得注意的是,与 RN-9893 (IC = 2.07 ± 0.90 μM) 相比,化合物和对 TRPV4 的抑制效力增加了 2.9 至 4.5 倍 (IC = 0.71 ± 0.21 μM 和 0.46 ± 0.08 μM)。两种化合物的 TRPV4 当前抑制率也显着优于 RN-9893(10 μM 时为 87.6 % 和 83.2 %,而 RN-9893 为 49.4 %)。首次在小鼠模型中对这些 RN-9893 类似物进行了分析,腹腔注射 10 mg/kg 或 10 mg/kg 可显着减轻脂多糖 (LPS) 诱导的急性肺损伤症状。这些结果表明化合物和化合物是治疗急性肺损伤的有希望的候选者。
