butanolide Nitro-C12-GBL, were cytotoxic at the micromolar scale, with higher activity on tumor HeLa cells than on HEK-293T of non-tumor origin. The structure of these molecules is simple but different from reported bioactive nitro compounds. Nitro-C12-GBL was generally more cytotoxic, but after short-term (2 h) exposure both compounds reached maximum cytotoxicity. At 72 h post-treatments of HeLa cells
合成了一系列生物活性对康酸 (PA) 的前体,并在体外对人体细胞进行了细胞毒性评估。两种两亲性含硝基前体 Nitro-C15-EED 和丁内酯 Nitro-C12-GBL 在微摩尔级具有细胞毒性,对肿瘤 HeLa 细胞的活性高于非肿瘤来源的 HEK-293T。这些分子的结构很简单,但与报道的生物活性硝基化合物不同。Nitro-C12-GBL 通常更具细胞毒性,但在短期(2 小时)暴露后,两种化合物均达到最大细胞毒性。在 HeLa 细胞处理 72 小时后,Nitro-C12-GBL (LC 50 = 21.9 µmol L -1 )的最终剂量反应接近于 Nitro-C15-EED (LC 50 = 25.3 µmol L -1),对应的 LC比 HEK-293T 低50 s ~ 3-3.6 倍。50 µmol L -1的短期处理这些化合物中的一种促进了可比的结果,将肿瘤细胞活力降低了 27-36%
