low toxicity and effective inhibitory activity against cisplatin-resistant oral cancer. The naturally produced pterostilbene was selected as the lead compound for design and synthesis of a series of bis(hydroxymethyl)propionate-based prodrugs. All derivatives were screened for antiproliferative effects against the cisplatin-resistant oral squamous (CAR) cell line and the results indicated that several
这项研究的目的是开发一种低毒且对顺铂耐药的口腔癌具有有效抑制活性的新药。选择天然生成的萜烯为主要化合物,用于设计和合成一系列基于双(羟甲基)丙酸酯的前药。筛选了所有衍生物对顺铂耐药的口腔鳞状细胞(CAR)细胞的抗增殖作用,结果表明,几种化合物均表现出优于蝶呤和白藜芦醇的抑制活性。其中,在CAR异种移植裸鼠模型中评估了最有前途的化合物12的体内抗肿瘤活性。在最低口服剂量(25 mg / kg /天)下观察到明显的抗肿瘤活性。增加剂量12至100 mg / kg / day可使肿瘤缩小至对照组的22%。基于这些发现以及在体内研究中观察到的极低毒性,我们认为化合物12可以作为进一步开发的新途径。
