摘要: 目的

为降低5-氟尿嘧啶(5-FU)毒性,设计并合成了5-FU乳糖苷衍生物,并初步探究其抗肿瘤活性。

方法

采用Vorbrüggen法合成5-FU乳糖苷衍生物,通过高分辨质谱(HRMS)、核磁共振氢谱(1HNMR)、核磁共振碳谱(13CNMR)、异核多量子相干谱(HMQC)及异核多键相关谱(HMBC)表征其结构,并用细胞计数试剂盒8(CCK-8)研究其体外毒性及抗肿瘤活性。

结果

用简单高效的方法合成了目标化合物ⅠaⅠb,并通过HRMS、1HNMR、13CNMR、HMQC及HMBC证实了ⅠaⅠb分别为N-1位及N-3位乳糖基取代的5-FU核苷衍生物;经CCK-8法验证较高浓度(0.7 μmol·mL-1ⅠaⅠb处理24 h对正常口腔角质形成细胞NOK生长的抑制率分别为30.28%及50.68%,均较5-FU的抑制作用弱(68.22%,P<0.05),其中Ⅰb对2种口腔鳞状细胞癌细胞的生长均有较显著的抑制作用,0.7 μmol·mL-1浓度下处理Cal-27细胞及UM SCC-47细胞24 h后抑制率分别为81.20%、80.19%。

结论

目标化合物ⅠaⅠb较5-FU具有较低毒性,且ⅠbⅠa具有更明显的抗口腔鳞状细胞癌细胞增殖活性。

Abstract: Objective

To reduce the toxicity of 5-fluorouracil (5-FU), design and synthesize 5-FU-lactoside derivatives, and preliminarily study their antitumor activities.

Methods

Target compounds were prepared with Vorbrüggenglycation procedures, the structures were characterized through high resolution mass spectrometry (HRMS), 1H nuclear magnetic resonance (1HNMR), carbon-13 nuclear magnetic resonance (13CNMR), heteronuclear multiple quantum correlation (HMQC), and heteronuclear multiple bond correlation (HMBC). A cell counting kit (CCK)-8 test was performed to examine their in vitro toxicity and antitumor activity. Experimental data were tested by χ2, and statistically significant differences were denoted by P<0.05.

Results

The target compounds were synthesized through a simple and efficient method. 1HNMR, 13CNMR, HMQC, HMBC, and HRMS confirmed that Ⅰa and Ⅰb were 5-FU nucleoside derivatives substituted with lactoside groups at N-1 and N-3, respectively. The CCK-8 test verified that high concentrations (0.7 μmol·mL-1) of Ⅰa and Ⅰb inhibited the growth of normal oral keratinocytes (NOK) by 30.28% and 50.68% after 24 h of treatment. Both values were lower than the inhibitory effect of 5-FU (68.22%; P<0.05). Ⅰb had a significant inhibitory effect on the growth of two oral squamous cell carcinoma cell lines. The inhibition rates of Cal-27 cells and UM SCC-47 cells treated with 0.7 μmol·mL-1 for 24 h were 81.20% and 80.19%, respectively.

Conclusion

Ⅰa and Ⅰb are less toxic than 5-FU. The antitumor activity of Ⅰb against oral squamous cell carcinoma cells is more obvious than that of Ⅰa.
