order to obtain a better antidote, we used natural product sesamol as the dominant fragment to redevelop clofibrate, an old lipid-lowering drug, and obtained the target compound clofibrate-sesamol (CF-S) by molecular hybridization strategy. Biological studies showed that CF-S can not only significantly improve liver function indexes, but also obviously reduce liver tissue damage. Relevant mechanisms showed
对乙酰氨基酚(APAP)作为一线药物广泛用于治疗镇痛解热药,可引起广泛的肝损伤甚至急性肝功能衰竭。氧化应激和炎症被认为是肝毒性的主要机制。然而,目前可供临床应用的解毒剂只有N-乙酰半胱氨酸,但它有副作用,大剂量后可能无效。其他报道的化合物虽然具有解毒作用,但存在剂量较大、作用机制不明或正在评价中等问题。为了获得更好的解毒剂,我们以天然产物芝麻酚为优势片段,对降脂老药安妥明进行再开发,通过分子杂交策略获得了目标化合物安妥明-芝麻酚(CF-S)。生物学研究表明,CF-S不仅能显着改善肝功能指标,还能明显减轻肝组织损伤。相关机制表明,CF-S可显着增加肝组织中Nrf2的表达,显着降低NF-κB p65的磷酸化。CF-S 可能通过 Nrf2/NF-κB 信号通路降低 APAP 诱导的肝毒性。
