- 產(chǎn)品描述: Idarubicin HCl (4-demethoxydaunorubicin (NSC256439, 4-DMDR) HCl,Idamycin, Zavedos) 是蒽環(huán)類抗生素Idarubicin的鹽酸鹽形式,抑制MCF-7細(xì)胞中的 DNA拓?fù)洚悩?gòu)酶II (topo II),無(wú)細(xì)胞試驗(yàn)中IC50為3.3 ng/mL。Idarubicin 可誘導(dǎo)mTOR依賴的細(xì)胞毒素的自噬
- 靶點(diǎn): Topo II (MCF-7 cells)(Cell-free assay):3.3 ng/mL; Multicellular spheroids(Cell-free assay):7.9 ng/mL
- 體外研究:
Idarubicin對(duì)多細(xì)胞球體具有顯著的細(xì)胞毒性,比得上對(duì)單層細(xì)胞的抗增殖作用。Idarubicin抑制CYP450 2D6。[2] Idarubicin分別比doxorubicin和epirubicin有效57.5倍和25倍。Idarubicin能夠克服P-糖蛋白介導(dǎo)的多藥耐藥性。Idarubicin抑制PMN超氧游離基的形成。Idarubicin能夠耦合到單克隆抗體(抗-Ly-2.1,抗-L3T4,或抗-Thy-1),并且保留蛋白質(zhì)溶解度和抗體活性。Idarubicin抑制NALM-6細(xì)胞的增殖,IC50為12 nM
- 體內(nèi)研究:
Idarubicin的還原取決于酮還原酶,產(chǎn)生比大多數(shù)酮更高的立體選擇性,引起幾乎完全的(13S)-差向異構(gòu)。Idarubicin還原的高立體選擇性可能是由于Idarubicin結(jié)構(gòu)中靠近羰基的不對(duì)稱中心存在下,手性誘導(dǎo)導(dǎo)致的
- 細(xì)胞實(shí)驗(yàn): Cell lines: NALM-6細(xì)胞 Concentrations: 0.1 nM-10 μM Incubation Time: 24小時(shí) Method: 復(fù)合物中的Idarubicin相比于游離藥物的抗增殖活性通過(guò)[3H]胸苷攝取的抑制測(cè)量。簡(jiǎn)而言之,NALM-6細(xì)胞(1.5 ×106/mL)加入平底微量滴定板(100 μL/well),在37℃下培養(yǎng)1小時(shí)。游離Idarubicin和Idarubicin-mAb復(fù)合物過(guò)濾滅菌并在無(wú)菌PBS中稀釋,以不同濃度重復(fù)3份加入孔中(100 μL/well),板在37oC,7% CO2下培養(yǎng)24小時(shí)。培育后,50 μL包含1 μCi [3H]胸苷的培養(yǎng)基加入每孔中,板進(jìn)一步培養(yǎng)4小時(shí)。將細(xì)胞采集到玻璃纖維濾紙上,干燥,并在閃爍計(jì)數(shù)器上計(jì)數(shù)。特異性研究使用相同的技術(shù)進(jìn)行,比較Idarubicin-抗-CD19偶聯(lián)物殺死CD19 +細(xì)胞的能力與不相關(guān)的Idarubicin-JGT偶聯(lián)物的細(xì)胞毒性。NALM-6細(xì)胞 (1.5×106/mL,300 μL 試管) 與不同濃度的Idarubicin-抗-CD 19或Idarubicin-JGT偶聯(lián)物在冰浴中培育30分鐘。然后在冰預(yù)冷的RPMI-1640 培養(yǎng)基(4 mL/wash)中洗滌3次,細(xì)胞重懸浮在新鮮培養(yǎng)基中,并轉(zhuǎn)移到96孔板(100 μL/well)。每個(gè)試管重復(fù)兩份建立,并且每管采集兩孔(每個(gè)藥物濃度一共4孔)。細(xì)胞用[3H]胸苷脈沖處理24小時(shí),然后采集
- 動(dòng)物實(shí)驗(yàn): Animal Models: 大鼠,兔子,小鼠,狗 Dosages: 2 mg/kg,0 mg/kg -75 mg/kg,3 mg/kg 和 0 mg/kg -75 mg/kg Administration: 靜脈注射給藥
