[体外研究]

当将5-氯-2'-脱氧尿苷(ClDU)置于组织培养基中时,哺乳动物细胞将类似物掺入DNA中。观察到培养基中10μM浓度的5-氯-2'-脱氧尿苷不改变细胞分裂动力学。以前已经表明,5-氯-2'-脱氧尿苷被代谢并使用选择性结合含有卤化碱基的DNA的抗体掺入DNA中。在这里报道的研究中,5-氯-2'-脱氧尿苷在作为T类似物时与BrdU更相似。 5-氯-2'-脱氧尿苷的毒性可部分归因于胸苷酸合成酶的抑制[1]。

[细胞实验]

在整个研究中使用人红白血病K-562细胞。首先以1.0×10 5个细胞/ mL接种细胞，并用10μM5-氯-2'-脱氧尿苷或10μM胸苷（阴性对照）处理63小时，或两次细胞倍增。通过台盼蓝排除计数细胞，通过离心沉淀（500×g）并用10mL无菌PBS [1]洗涤。

[动物实验]

大鼠[2]使用体重200-250g的成年雄性Wistar大鼠。首先，允许动物以0.05mg / kg /注射剂量自行给予甲基苯丙胺，以固定比例1（FR1）为基线时段。之后，将大鼠分成四组。两组大鼠（长期进入; LgA-4天（d），LgA-13d;每组n = 7）允许自身给予0.05mg / kg /注射甲基苯丙胺每天6小时，而其他组（短途访问; ShA-4 d，ShA-13 d;每组n = 7）允许每天1小时。所有程序都在黑暗循环期间执行。在第5天，ShA-4d和LgA-4d大鼠接受一次注射50mg / kg 5-氯-2'-脱氧尿苷并存活30分钟。在第14天，ShA-13d和LgA-13d在2小时后接受一次注射50mg / kg的5-碘-2'-脱氧尿苷，然后注射50mg / kg的5-氯-2'-脱氧尿苷。在注射5-氯-2'-脱氧尿苷后，这些大鼠也存活30分钟。平行组的药物初始大鼠（n = 6）接受一次注射50mg / kg IdU，然后在2小时后接受50mg / kg 5-氯-2'-脱氧尿苷。这些大鼠在注射5-氯-2'-脱氧尿苷后也能存活30分钟[2]。
