生物活性:Gemcitabine (LY 188011) 是一種嘧啶核苷類似物抗代謝物和抗腫瘤藥。吉西他濱抑制DNA合成和修復(fù),導(dǎo)致自噬和細(xì)胞凋亡[1][2]< /sup>。 IC50 和目標(biāo):DNA 合成[1]
體外:Gemcitabine(購(gòu)自 MedChem Express,0.003-1 μM;3 天)有效且有效地殺死小鼠和人類衰老細(xì)胞[4]。
Gemcitabine 抑制 BxPC-3、Mia Paca-2、PANC-1、PL-45 和 AsPC-1 細(xì)胞的生長(zhǎng),IC50分別為 37.6、42.9、92.7、89.3 和分別為 131.4 nM[1]。
體內(nèi):吉西他濱可通過(guò)氣管內(nèi)噴霧給大鼠給藥,無(wú)明顯毒性,最大耐受劑量為 4 mg/kg,每周一次,持續(xù) 9 周。在 2、4 和 6 mg/kg 劑量下,吉西他濱通過(guò)肺部給藥的毒性低于口服給藥[2]。
LSL-Kras 的治療G12D/+ ; LSL-Trp53R172H;與安慰劑組相比,使用吉西他濱(50 mg/kg,ip)或 DMAPT/吉西他濱組合的 Pdx-1-Cre 小鼠的中位生存時(shí)間顯著增加超過(guò) 30 天(分別為 254.5 或 255 天與 217.5 天) )[3].
