Synthesis of new betulinic acid–peptide conjugates and in vivo and in silico studies of the influence of peptide moieties on the triterpenoid core activity
Several novel betulin derivates were prepared using Mannichreactions as a key step. Starting from 3‐ethynyl‐3‐hydroxy‐lup‐20(29)‐ene derivatives, copper‐catalyzed Mannichreactions yielded hydroxypropargyl ammonium hydrochlorides or their corresponding methiodides. All compounds were screened in a sulforhodamine B assay for their antitumor activity using a panel of 9 human cancer cell lines. Some
使用曼尼希反应作为关键步骤制备了几种新型桦木脑衍生物。从 3-乙炔基-3-羟基-lup-20(29)-烯衍生物开始,铜催化的曼尼希反应生成羟基炔丙基铵盐酸盐或其相应的甲硫醚。使用一组 9 个人类癌细胞系,在磺基罗丹明 B 试验中筛选所有化合物的抗肿瘤活性。其中一些化合物显示出显着的细胞毒性;它们通过触发细胞凋亡起作用,如额外的吖啶橙/碘化丙啶测定、台盼蓝测试、DNA 阶梯实验和细胞周期研究所示。
