毒理性
  • 在妊娠和哺乳期间的影响
◉ 母乳喂养期间的总结使用:大多数来源认为,在母体抗肿瘤药物治疗期间,母乳喂养是禁忌的。在间歇性去氧脱氧核苷治疗期间,如果有一个适当的禁乳期,可能可以安全地进行母乳喂养;制造商建议在最后一剂后的禁乳期为1周。化疗可能会不利地影响母乳的正常微生物组和化学成分。在怀孕期间接受化疗的妇女更有可能在哺乳婴儿时遇到困难。 ◉ 对母乳喂养婴儿的影响:截至修订日期,没有找到相关的已发布信息。 ◉ 对泌乳和母乳的影响:对74名在怀孕第二或第三季度在一家中心接受癌症化疗的妇女进行了电话随访研究,以确定她们产后是否成功进行母乳喂养。只有34%的妇女能够专门母乳喂养她们的婴儿,而66%的妇女报告遇到母乳喂养困难。这与其他22位在怀孕期间被诊断但未接受化疗的母亲91%的母乳喂养成功率形成了对比。其他具有统计学意义的相关性包括:1)有母乳喂养困难的母亲平均接受了5.5个周期的化疗,而没有困难的母亲平均接受了3.8个周期;2)有母乳喂养困难的母亲在怀孕期间平均提前3.4周接受了第一次化疗周期。在接受含氟尿嘧啶方案的9名妇女中,有8名遇到母乳喂养困难。
◉ Summary of Use during Lactation:Most sources consider breastfeeding to be contraindicated during maternal antineoplastic drug therapy. It might be possible to breastfeed safely during intermittent decitabine therapy with an appropriate period of breastfeeding abstinence; the manufacturer recommends an abstinence period of 1 week after the last dose. Chemotherapy may adversely affect the normal microbiome and chemical makeup of breastmilk. Women who receive chemotherapy during pregnancy are more likely to have difficulty nursing their infant. ◉ Effects in Breastfed Infants:Relevant published information was not found as of the revision date. ◉ Effects on Lactation and Breastmilk:A telephone follow-up study was conducted on 74 women who received cancer chemotherapy at one center during the second or third trimester of pregnancy to determine if they were successful at breastfeeding postpartum. Only 34% of the women were able to exclusively breastfeed their infants, and 66% of the women reported experiencing breastfeeding difficulties. This was in comparison to a 91% breastfeeding success rate in 22 other mothers diagnosed during pregnancy, but not treated with chemotherapy. Other statistically significant correlations included: 1) mothers with breastfeeding difficulties had an average of 5.5 cycles of chemotherapy compared with 3.8 cycles among mothers who had no difficulties; and 2) mothers with breastfeeding difficulties received their first cycle of chemotherapy on average 3.4 weeks earlier in pregnancy. Of the 9 women who received a fluorouracil-containing regimen, 8 had breastfeeding difficulties.

    一种地西他滨的合成与工业化生产方法
    摘要:
    本发明涉及一种地西他滨的合成与工业化生产方法,即以2-脱氧-D-核糖为原料,与甲醇反应得到甲苷,3,5-二羟基用9-芴甲氧羰基保护,然后与氯化氢反应得到1-氯芴糖,1-氯芴糖再与硅烷化的5-氮杂胞嘧啶反应,然后脱保护基,精制后得到地西他滨。本发明的特点是1-氯芴糖与硅烷化的5-氮杂胞嘧啶缩合反应中不需要四氯化锡,避免原料药中重金属超标的问题;同时控制三氟甲磺酸三甲基硅酯的量和反应条件,使产物中β体含量增加。
