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

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。
