| 背景说明 | K858是一种 ATP 非竞争性的驱动蛋白 Eg5 抑制剂。 |
| 生物活性 | K858 Racemic is an ATP-uncompetitive inhibitor of kinesin Eg5 with an IC50 of 1.3 μM.[1-2] |
| In Vitro | K858 Racemic is an ATP-uncompetitive inhibitor of Eg5 with an IC50 of 1.3 μM. K858 does not inhibit the ATPase activity of the mitotic kinesins CENP-E and MKLP1， or the conventional kinesin heavy chain even at 200 μM. K858 induces mitotic arrest and growth inhibition via the activation of the Mad2-mediated spindle checkpoint. K858 (5 μM) induces mitotic cell death in cancer cells but not in normal cells[1]. K858 (1， 10， 100 μM) inhibits the MCF7， BT474 and SKBR3 cell lines， and only at 10 and 100 μM suppresses MDA-MB231 cell line after treatment for 24 h. K858 incereases Bax/Bcl2 RNA ratio and survivin in the four cell lines. Furthermore， the up-regulation of survivin is totally reversed by wortmannin (phosphoinositide 3-kinase AKT) in MCF7 cells[2]. |
| In Vivo | K858 (50， 150 mg/kg， p.o.) shows antitumor activity in an A2780 ovarian cancer xenograft model， also inhibits tumor grwoth in a HCT116 colon cancer xenograft model via 100 mg/kg twice a day orally for 5 days. K858 (100 mg/kg， p.o.， qd ×5) displays no neurotoxic side effects in mice[1]. |
| 细胞实验 | To determine cytotoxicity， sulforhodamine B colorimetric assay is performed: 1.5 × 104 cells are plated on 96 well plates， grown for 24 h (h) and treated with different concentrations of K858 (1 μM， 10 μM， 100 μM) for 24 and 48 h. Cells are then fixed with 50 % trichloroacetic acid for 1 h at 4°C and stained for 30 min at room temperature (RT) with 0.4 % sulforhodamine B in 1 % acetic acid. Excess dye is removed by washing four times with 1 % acetic acid. Protein bound dye is dissolved in 10 mM TRIS pH 10， and optical density (OD) is determined at 510 nm using a microplate reader[2]. |
| 动物实验 | A2780 cells (5 × 106 cells) are inoculated s.c. into BALB/cAJcl-nu mice. K858 is administered orally twice daily on days 0 to 4， and 7 to 11 at 150 and 50 mg/kg. Doses and schedules are determined by the tolerability studies performed in advance. Vehicle (0.5% methylcellulose 400) is administered orally as a control twice daily on days 0 to 4， and 7 to 11. Paclitaxel is administered i.v. on day 0 at 25 mg/kg. Carboplatin is administered i.v. on day 0 at 60 mg/kg. Drug efficacy is expressed as the ratio of the mean experimental V/V0 value to that of the control group [treated versus control (T/C) ratio]， where V is the tumor volume at the day of evaluation and V0 is the tumor volume at the day of the initial treatment with the drug. Statistical analysis is performed using the nonparametric rank-sum test[1]. |

污染的细菌。 “无变化”系指微生物数不增减例如冷冻食品或干燥食品。 “增加”系指将食品保存在不良环境中使微生物易于繁殖和产毒。 根据上表15种情况的举例，1-3可用三级法，4-5可用二级法来判定是否合格。 考虑到以上15种情况，分别设定不同的取检样数及检样污染数，在1-9例种检样需采5个（n=5），而污染检样数设定为c=3,2,1。在10-15例用二级法则不得检出该致病菌c=0.例如冷冻食品，细菌数按例2,大肠菌按例5,金黄色葡萄球菌按例8，沙门氏菌按例11的二级法判定。 对食品处理应酌情
