靶点活性

Microtubule:4 nM

体内活性

方法:为研究低剂量 Paclitaxel 对肿瘤侵袭的影响,将 Paclitaxel (2.6 mg/kg) 腹腔注射给药给携带胆管癌肿瘤 EGI-1 的 SCID 小鼠,每天一次,持续两周。 结果:低剂量 Paclitaxel 治疗减少了 EGI-1 细胞的肺扩散,而不显著影响其局部肿瘤生长。[4] 方法:开发 Paclitaxel 醇诱导的负面情感症状的临床前模型,将 Paclitaxel (2-8 mg/kg in 1 volume ethanol+1 volume Emulphor-620 +18 volumes distilled water) 腹腔注射给 C57BL/6J 小鼠,每两天一次,共注射四次。 结果:8 mg/kg Paclitaxel 处理导致机械性和冷性异常性疼痛的发展和维持。Paclitaxel 也诱导了焦虑样行为和抑郁样行为。Paclitaxel 在小鼠情感状态建模试验中产生了行为改变,而伤害性反应的增加持续时间更长。[5]

体外活性

方法:人 T 细胞淋巴细胞白血病细胞 CCRF-HSB-2 用 Paclitaxel (0.01-1 μM) 处理 48 h,使用 MTT 方法检测细胞生长抑制情况。 结果:Paclitaxel 剂量依赖性地抑制 CCRF-HSB-2 细胞生长,IC50 为 0.25 μM。[1] 方法:人胃癌细胞 AGS 用 Paclitaxel (10-160 nM) 处理 24-48 h,使用 Western Blot 方法检测靶点蛋白表达水平。 结果:Paclitaxel 诱导凋亡相关蛋白 cleaved caspase-3 和 cleaved PARP 表达上调。[2] 方法:犬乳腺肿瘤细胞 CHMm 用 Paclitaxel (0.01-1 μM) 处理 24 h,使用 Flow Cytometry 方法检测细胞凋亡情况。 结果:Paclitaxel 剂量依赖性诱导 CHMm 细胞凋亡。[3]

溶解度

DMSO:41.66 mg/mL (48.79 mM); Ethanol:21.4 mg/mL (25.06 mM);

细胞实验

1×10^4 cells are plated in 100 μL of the growth medium in the presence or absence of increasing concentrations (0.1-1 μM) of taxol in 96-well plates and cultured at 37°C in 5% CO2 for 12-48 h. The cells are then incubated with 25 μL of MTT (5 mg/mL) at 37°C for 4 h. After dissolving the crystals with 0.04 N HCl in isopropanol, the plates are read in a microplate reader at 570 nm [1].

动物实验

Adult (250-320 g) male Sprague-Dawley rats are used for all experiments. One week following the DiI injection, rats are anesthetized with isofluorane and injected into the tail vein with 2 mg/kg paclitaxel or its vehicle (1:1:23, cremophor EL:ethanol:0.9% saline). The tail vein injection is repeated three more times every other day for a total of four injections [4].
