IC50 & Target[1]

Topoisomerase I

 

体外研究
(In Vitro)

(±)-10-Hydroxycamptothecin (10-OH-camptothecin) is an inhibitor of topo I[1]. (±)-10-Hydroxycamptothecin (10-HCPT, 5-20 nM) markedly inhibits the proliferation of Colo 205 cells in a dose-dependent manner. (±)-10-Hydroxycamptothecin (5-20 nM) arrests Colo 205 cells in the G2 phase of the cell cycle and triggers apoptosis through a caspase-3-dependent pathway[2]. (±)-10-Hydroxycamptothecin (HPT, 0.01-10 μg/mL) causes cell shrinage, nuclear fragmentation and condensed chromosomes and induces apoptosis of human urinary bladder cancer cell line (T24)[3].

体内研究
(In Vivo)

(±)-10-Hydroxycamptothecin (10-HCPT, 2.5-7.5 mg/kg/2 days, p.o.) significantly suppresss tumor growth in mouse xenografts. (±)-10-Hydroxycamptothecin (1-7.5 mg/kg, p.o., once per 2 or 4 days) causes no obvious acute toxicity in nude mice[2].

请根据您的 实验动物和给药方式 选择适当的溶解方案。

以下溶解方案都请先按照 In Vitro 方式配制澄清的储备液，再依次添加助溶剂：
——为保证实验结果的可靠性，澄清的储备液可以根据储存条件，适当保存；体内实验的工作液，建议您现用现配，当天使用；
以下溶剂前显示的百分比是指该溶剂在您配制终溶液中的体积占比；如在配制过程中出现沉淀、析出现象，可以通过加热和/或超声的方式助溶

  • 方案 一

    请依序添加每种溶剂： 10% DMSO    90% (20% SBE-β-CD in Saline)

    Solubility: 2.5 mg/mL (6.86 mM); 悬浊液; 超声助溶

    此方案可获得 2.5 mg/mL的均匀悬浊液，悬浊液可用于口服和腹腔注射。

    以 1 mL 工作液为例，取 100 μL 25.0 mg/mL 的澄清 DMSO 储备液加到 900 μL 20% 的 SBE-β-CD 生理盐水水溶液 中，混合均匀。

    20% SBE-β-CD in Saline 的配制（4°C，储存一周）：2 g SBE-β-CD（磺丁基醚 β-环糊精）粉末定容于 10 mL 的生理盐水中，完全溶解至澄清透明。

Cell Assay
[2]

Colo 205 cells (5 × 105) (ATCC: CCL-222) are seeded in 25T flasks overnight and then treated without (control) and with 5, 10, 15 or 20 nM of (±)-10-Hydroxycamptothecin, respectively. After treatment for 24-120 h, cells are harvested by trypsin-EDTA and then centrifuged at 1,500 rpm for 5 min at 4˚C. The cell pellet is resuspended in culture medium containing 0.04% trypan blue and the viable cells are enumerated by a hemocytometer[2].

Animal Administration
[2]

BALB/c-nu mice are housed in a laminar flow room under sterilized conditions with a maintained temperature of 25 ± 2˚C and a controlled 12-h light and 12-h dark cycle. The Colo 205 cells are harvested and resuspended in serum-free RPMI-1640 medium. Cells are adjusted to 1 × 107 cells/mL, and transplanted 0.1 mL subcutaneously to the flank regions of the mice. Each experimental group included six to seven mice bearing tumors. (±)-10-Hydroxycamptothecin is dissolved in propylene glycol and treatment begins when the tumor size reach 3-5 mm. (±)-10-Hydroxycamptothecin is administered via p.o. once per two or four days at doses of 1, 2.5, 5, 7.5 mg/kg (volume of injection: 0.1 mL/20 g of body weight), respectively. The control group receives propylene glycol vehicle once per two days. Tumor size and body weight are monitored twice a week throughout the experiment. The tumor size is measured using a vernier caliper. Tumor volume (V) is calculated according to the formula: V (mm3) = 0.4AB2, where A and B are the longest diameter and the shortest diameter, respectively. At the end of the experiment, all mice are sacrificed by CO2 gas. Tumors, livers, kidneys and lungs are collected, fixed, embedded and stained with hematoxylin and eosin for pathological analysis[2].

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.
