Various 2'- and 3'-methylidene-substituted nucleoside analogues have been synthesized and evaluated as potential anticancer and/or antiviral agents. Among these compounds, 2'-deoxy-2'-methylidene-5-fluorocytidine (22) and 2'-deoxy-2'-methylidenecytidine (23) not only demonstrated potent anticancer activity in culture against murine L1210 and P388 leukemias, Sarcoma 180, and human CCRF-CEM lymphoblastic
已经合成了各种2'-和3'-亚甲基取代的核苷类似物,并将其评估为潜在的抗癌剂和/或抗病毒剂。在这些化合物中,2'-脱氧-2'-亚甲基-5-氟胞苷(22)和2'-脱氧-2'-亚甲基胞苷(23)不仅在培养中表现出对鼠L1210和P388白血病,肉瘤180的有效抗癌活性。 ,人CCRF-CEM淋巴母细胞性白血病,其ED50值分别为1.2和0.3 microM,0.6和0.4 microM,1.5和1.5 microM,0.05和0.03 microM,但在小鼠L1210白血病中也有活性。在所有测试的药物剂量水平(分别为25、50和75 mg / kg)中,化合物23没有毒性死亡,而化合物22在最高剂量水平下仅产生一个毒性死亡。相反,在同一项研究中,1-β-D-阿拉伯呋喃糖基胞嘧啶(ara-C)分别导致2 / 5、5 / 5和5/5毒性死亡。化合物22和23均显示出比ara-C更好的抗癌活性,产生更高的T
