Twenty -substituted pyrrolo[3,4-]quinoline-1,3-diones were synthesized by a cyclization reaction of Pfitzinger's quinoline ester precursor with the selected aromatic, heteroaromatic and aliphatic amines. The structures of all derivatives were confirmed by IR, H NMR, C NMR and HRMS spectra, while their purity was determined using HPLC techniques. Almost all compounds were identified as a new class ofpotent
通过 Pfitzinger 喹啉酯前体与选定的芳香胺、杂芳香胺和脂肪胺的环化反应合成了二十个取代的吡咯并[3,4-]喹啉-1,3-二酮。所有衍生物的结构均通过IR、H NMR、C NMR 和HRMS 光谱进行确认,同时使用HPLC 技术测定其纯度。几乎所有化合物都被鉴定为一类新的hDHODH强效抑制剂,其中 和 是活性最强的化合物,其IC50值相同,为0.11 μM,比参考药物来氟米特好约7倍。这两种衍生物还对健康 HaCaT 细胞表现出非常低的细胞毒性作用,并在生理 pH 值下通过实验获得了最佳亲脂特性,logP 值分别为 1.12 和 2.07。我们进一步评估了三种最活跃的化合物和参考药物来氟米特的毒理学影响的比较差异。将大鼠分为5组,腹腔注射治疗,对照组(I组)单剂量来氟米特(20 mg/kg),II组,其余三组(III、IV、V)腹腔注射,(20毫克/千克体重)单独。通过检查血清生
