Et-743类似物的合成：由于化合物14 C-1位的保护基没能脱除，所以我们决定调整合成路线，采用了先将化合物13的C-1位的保护基脱除，再将C-21位羰基还原氰基化的策略。

UCK is able to catalyze phosphorylation of its physiological substrate uridine and cytidine, and it also plays important roles for the phosphorylation of nucleoside analogs that are being investigated for possible use in chemotherapy of cancer, such as 6-azauridine, 5-fluorouridine and so on.

将表达UCK不同丰度的肝癌细胞进行6-氮尿苷的敏感试验显示，6-氮尿苷对UCK表达量较高的HepG2细胞的毒性作用强于对UCK表达量较低的L02细胞，提示UCK有可能成为临床用药的一个参考指标，克隆人类尿苷胞苷激酶对寻找新的嘧啶核苷类似物并研究它们的药理活性有着重要的意义。

Thymidine analogs, including bromodeoxyuridine, chlorodeoxyuridine, iododeoxyuridine, and tritiated thymidine, label diiding cells by incorporating into DNA during S phase of cell diision and are widely employed to identify cells transplanted into the central nerous system.

中文摘要：胸苷类似物包括溴脱氧尿苷、氯脱氧尿苷、碘苷和氚标记的胸苷，它们可以在细胞分裂的S期整合入待标记的分裂细胞，因此，被广泛地用于鉴定中枢神经系统细胞移植。

The results showed that the insulin-induced oocyte maturation was accompanied by the decreases in membrane potential, K+ transference number and intracellular K+ and H+ activities, and the increases in intracellular Na+ and Cl- activities.

Malle：等(198们的实验也证实了胰岛素及其类似物的这种作用。Lessman等〔1984)曾报道，胰岛素在促进卵母细胞成熟同时，膜的某些特性发生了变化，如膜阻抗增加，膜电容减少和膜电位降低去极化〕等。

Membrane potential, intracellular Na+, K+, Cl, H+ activities and Na+, K+ transference number in toad oocytes were measured in vitro by using conventional and ion-sensitive microelectrodes during the insulin-induced oocyte maturation.

近年来，胰岛素及胰岛素样肤类物质在卵母细胞成熟中的作用越来越引起人们的关注。EI一Etr等(1979)用非洲爪蟾卵母细胞作实验，发现胰岛素及其类似物具有促进卵母细胞成熟分裂的作用。

Adefovir, which was recently approved has a comparable efficacy with a very low frequency of resistance.

阿德福韦是近来批准上市的一个新的具有相似疗效且发生药物抵抗率较低的核苷类似物。

But it in 10"8mol/L-10"mol/L inhibited gastrin secretion .whereas it promoted somatostatin secretion of duodenum in vitro. GnRH-A did not effect significantly gastrin and somatostatin secretion of stomach in vitro.These results suggested that GnRH-A may integrate with GnRH receptor and restrain directely gastric acid secretion in parietal cell.

综上所述，我们认为胃腔内的Gn尺H类似物可能首先和壁细胞上GnRE受体结合，直接抑制壁细胞胃酸的分泌，由于胃酸分泌减少反馈性地刺激胃泌素细胞，促进其合成及分泌胃泌素，胃酸分泌减少同时也反馈性的抑制生长抑素的释放，反馈性地抑制胃肠壁内EC细胞分泌5一HT。
