鹽酸吉西他濱是一種DNA合成抑制劑，其IC50值為240.4±29.0微米(CCRF-CEM/dCK/細胞)、14.7±2.8納米(TC-1細胞)、36.7±5.1微米(TC-1-GR細胞)和50納米(PANC1細胞)[1]。 DNA合成是DNA分子的自然或人工創(chuàng)造，可以定義為DNA復(fù)制、聚合酶鏈式反應(yīng)和基因合成。據(jù)報道，DNA合成過程在多種癌癥中起著重要作用，許多藥物已被制成針對這一過程來抑制腫瘤生長或轉(zhuǎn)移[2] [3]。

鹽酸吉西他濱是一種DNA合成抑制劑。當(dāng)用胰腺癌細胞系COLO 357和L3.6pl進行測試時，繼染料木黃酮(其使細胞對鹽酸吉西他濱敏感)之后的鹽酸吉西他濱治療顯著抑制了細胞生長并增加了細胞凋亡[4]。在MIA PaCa-2細胞中，鹽酸吉西他濱通過抑制dDNA的活性對細胞表現(xiàn)出顯著的細胞毒性，IC50值為49.7±17.7nM[1]。 在原位植入COLO 357細胞的SCID小鼠中，與對照組相比，經(jīng)染料木黃酮和吉西他濱治療的小鼠顯著降低(75%，P < 0.01)腫瘤生長和體重[4]。
