- 產(chǎn)品描述: Niraparib tosylate (MK-4827, ZEJULA) 是PARP1/PARP2的選擇性抑制劑,IC50分別為3.8 nM和2.1 nM。Niraparib可增加PARP-DNA復(fù)合體的形成,并導(dǎo)致DNA損傷、凋亡和細(xì)胞死亡
- 靶點(diǎn): PARP2(Cell-free assay):2.1 nM; PARP1(Cell-free assay):3.8 nM;Apoptosis;?PARP
- 體外研究:
微摩爾級(jí)濃度的niraparib使來(lái)自于肺癌、乳腺癌以及前列腺癌的腫瘤細(xì)胞對(duì)放射線敏感(不依賴于它們的p53狀態(tài)),而對(duì)來(lái)自于正常組織的細(xì)胞沒(méi)有此作用。Niraparib同樣還可以使腫瘤細(xì)胞對(duì)過(guò)氧化氫敏感、在DNA復(fù)制時(shí),將過(guò)氧化氫誘導(dǎo)的單鏈斷裂轉(zhuǎn)變?yōu)殡p鏈斷裂
- 體內(nèi)研究:
MK-4827可以增強(qiáng)放射線對(duì)多種人類腫瘤異種移植的作用,無(wú)論是在p53野生型或是p53突變體。MK-4827在給藥后1小時(shí)降低腫瘤中PAR水平并持續(xù)效果24小時(shí)。MK-4827體內(nèi)給藥能延長(zhǎng)放射線處理后的動(dòng)物壽命。MK-4827和放射治療結(jié)合,顯著提高腫瘤中裂解的caspase-3和γ-H2AX的水平
- 細(xì)胞實(shí)驗(yàn): Cell lines: V-C8細(xì)胞 Concentrations: 50 nM Incubation Time: 24 h Method: 用PARP抑制劑MK-4827對(duì)中國(guó)倉(cāng)鼠細(xì)胞V-C8(BRCA2-negative)進(jìn)行處理,24小時(shí)后,洗滌并將細(xì)胞孵育在不含此化合物的培養(yǎng)基中5-7天,直到形成克隆
- 動(dòng)物實(shí)驗(yàn): Animal Models: 雌性裸鼠(Ncr Nu/Nu) Dosages: 25或50 mg/kg Administration: 口服
