Parthenolide is a natural product that exhibits anti-leukaemic activity, however, its clinical use is limited by its poor bioavailability. It may be extracted from feverfew and protocols for growing, extracting and derivatising it are reported. A novel parthenolide derivative with good bioavailability and pharmacological properties was identified through a screening cascade based on in vitro anti-leukaemic
小白菊内酯是一种具有抗白血病活性的天然产物,但其临床应用受限于其较差的生物利用度。它可以从小白菊中提取,并报告了生长、提取和衍生它的协议。通过基于体外抗白血病活性和计算的“药物相似性”特性、体外和体内药代动力学研究和 hERG 敏感性测试的筛选级联,鉴定了一种具有良好生物利用度和药理学特性的新型小白菊内酯衍生物。体外研究表明,最有希望的衍生物具有与先前描述的小白菊内酯衍生物 DMAPT 相当的抗白血病活性。新发现的化合物被证明具有促氧化活性,并且计算机分子对接研究表明了一种前药作用模式。提出了用于生产5f的胺7的合成方案。
