acids bearing amide moiety were designed and synthesized by Doebner reaction. Human dihydroorotate dehydrogenase (hDHODH) was recognized as a biological target and all compounds were screened as potential hDHODH inhibitors in an enzyme inhibition assay. The prepared heterocycles were also evaluated for their cytotoxic effects on the healthy HaCaT cell line while lipophilic properties were considered
通过 Doebner 反应设计并合成了 20 种带有酰胺部分的新型 2-取代喹啉-4-羧酸。人类二氢乳清酸脱氢酶 ( h DHODH) 被认为是生物靶标,所有化合物都在酶抑制试验中被筛选为潜在的h DHODH 抑制剂。还评估了制备的杂环对健康 HaCaT 细胞系的细胞毒性作用,同时根据生理 pH 值下实验确定的 logD 值考虑了亲脂性。最有前途的化合物5j,在末端苯环的对位有氯,显示出良好的hDHODH 抑制活性、低细胞毒性和最佳亲脂性。通过分子对接确定的h DHODH上5j的生物活性构象揭示了该化合物的药理学,并为进一步优化先导化合物提供了指导。
