12、，本品对人微血管内皮细胞株HHEC的迁移、Tube 形成有抑制作用，并能明显抑制鸡胚尿囊膜血管生成，提示本品具有一定的体外抗血管生成作用。此外，本品对人肺腺癌细胞SPC-A4有一定的生长抑制作用。体内实验结果显示，本品对鼠肿瘤模型（S180肉瘤、H22肝癌），人异种移植肿瘤（SPC-A4肺腺癌、SGC7901胃癌、Hela宫颈癌、SMMC-7721 和Bel7402肝癌）有抑瘤作用。 毒理作用安全药理学：静脉注射本品高、中、低剂量组1.5、3、6 mgkg（2.4×104、4.8×104、9.6×104 U/kg），麻醉犬的血压、呼吸及心电图指标在给药前、后无明显

13、改变，小鼠自主活动次数未受影响。动物溶血性、刺激性和过敏反应：本品0.08 mgml在观察时间内无溶血及红细胞凝集现象；豚鼠间日腹腔注射本品0.5 ml只（0.036 mgml），连续3次，第一次给药后14天及21天静脉注射本品1 ml只（0.036 mgml），均未发生过敏反应；家兔静脉刺激性试验未见明显的血管扩张、红肿等刺激反应，未见管壁增厚等形态学改变。急性毒性：本品小鼠静脉或腹腔给药的LD50大于450.5 mg（7.2×106U）/kg。长期毒性：大鼠的长期毒性试验显示，连续腹腔注射3、6、12 mg/kg/day（4.8×104 、9.6×104 、1

14、9.2×104 U/kg/day）三个剂量组共45天，给药结束后及停药21天，各组动物的脏器如心、肝、脾、肺、脑、胃、小肠、子宫、睾丸等脏器与对照组比较均未见明显病理形态学改变。Beagle犬的长期毒性试验显示，连续静脉注射2、10、25 mg/kg/day（3.2×104 、16.0×104 、40.0×104 U/kg/day）三个剂量组共13周，对Beagle犬无明显毒性靶器官，不良反应为血液网织红细胞增高，但停药后可恢复，并无延迟性毒性反应。猕猴的长期毒性试验显示，连续静脉注射3 mg（4.8×104 U）/kg/day (50.4 m

15、g/m2)，10 mg（1.6×105 U）/kg/day (167.9 mg/m2)，30 mg（4.8×105 U）/kg/day (503.7 mg/m2)三个剂量组共9个月，各组猕猴体征、外观行为、活动等均未见明显异常反应。体重与进食量、血液学、血液生化学、心电图和尿液检查结果均在正常值范围内波动，提示对肝、肾功能无明显损伤。此外，蛋白质、脂肪、糖代谢基本正常。病理组织学结果显示，连续9个月静脉给药，32只猕猴脏器系数各组无明显差异，未见与药物剂量相关的异常变化，提示本品在小于30 mg（4.8×105 U）/kg/day (503.7 mg/m2)的剂量

16、范围内连续静脉注射给药9个月，未见明显毒性反应，为安全剂量。【药代动力学】健康志愿者单次30 min内静脉滴注本品30 mg（4.8×105 U）和60 mg（9.6×105 U）/m2，及120 min内静脉滴注120 mg（19.2×105 U）和210 mg（33.6×105 U）/m2（滴注速率分别为1、2及1和1.75 mg/m2/min），其末端消除半衰期（t1/2）为10小时左右，全身清除率(CLs)为2.8 L/h/m2左右。本品在30120 mg/m2（4.8×105 19.2×105 U/m2）剂量范围于正常人体内

17、呈近似线性药代动力学，可以用线性模型预测不同剂量、滴注速率和时间的血药浓度。滴注速率、时间和总剂量均可影响AUC和峰浓度水平。肿瘤患者每日2小时内静脉滴注本品，连续28天，个体间药时曲线差异性很大。谷浓度随给药次数增加有持续增高的趋势，总剂量和滴注次数可影响峰浓度和谷浓度水平。正常小鼠静脉给药后泌尿排泄系统的浓度最高，肾、尿、肺和肝高于血浆，其它组织均低于血浆，肌肉、脂肪、和脑浓度最低。荷瘤小鼠静脉注射本品后全身分布与正常小鼠相近，肿瘤组织中分布不高，与肌肉和脂肪组织浓度相近。【抗体产生】用酶联免疫吸附试验间接ELISA法检测猕猴连续9个月静脉注射重组人血管内皮抑制素血清中抗体IgG。给药后产

18、生的抗体与剂量、时间有关，剂量越高产生抗体的猕猴数量越多，且产生抗体的滴度也越高。抗体在给药1个月后就能检测到抗体、抗体滴度随时间发生变化，一般给药前3个月抗体滴度较稳定，而5、7、9、10个月抗体滴度下降，甚至抗体消失。通过采用细胞测活方法分析血清中本品的活性，结果活性没有变化，表明产生的抗体为非中和抗体。人的抗体测定方法同上，检测患者血清中抗本品的IgA、IgG、IgM、IgE及抗His-tag抗体。在接受检测的31例受试患者中，治疗组20例，对照组11例，结果治疗组2例出现显示抗本品抗体IgA阳性，产生时间分别是第32 天、24月，1例出现抗His-tag抗体IgA阳性，对照组2例显示I

19、gG阳性，滴度均为110，其余患者治疗后均检测不出抗体反应。低滴度（110）的抗血清抗体体外试验未见中和本品生物活性的作用。【贮藏】于28避光保存和运输。【包装】3.0 ml预灌封注射器包装，PVC吸塑泡罩密封包装，每盒 1 支，14 支/中盒，8 中盒/箱。【有效期】暂定18个月【执行标准】试行标准 YBS【批准文号】国药准字S【生产企业】企业名称：山东先声麦得津生物制药有限公司生产地址：山东省烟台经济技术开发区荣昌路1号邮政编码：电话：0535-， 免费电话：800-传真：0535-网址： E-mail：Approved on September 12, 2005 Revised on J

It inhibits the metastasis of angiogenesis endothelial cells, inhibits the formation of tumor new blood vessel, obstructs the nutrition supply of tumor cells, and thu

50、s inhibits the proliferation or metastasis of tumor. As shown by in vitro test results, ENDOSTAR inhibits the metastasis of HHEC and the formation of Tube, significantly inhibits the angiogenesis of chicken embryo allantoic membrane. Thus, ENDOSTAR suppresses angiogenesis in vitro to a certain exten

51、t. In addition, it inhibits the growth of human lung adenocarcinoma cells SPC-A4 to a certain extent. As shown by in vivo test results, ENDOSTAR has extensive effects of inhibiting the mouse tumor model (S180 sarcoma, H22 liver cancer) and human xenograft tumor (SPC-A4 lung adenocarcinoma, SGC7901 s

52、tomach cancer, Hela cervical carcinoma, SMMC-7721 and Bel7402 liver cancer). 2. Toxicological action General Pharmacology: After the intravenous injection of 1.5, 3 and 6mg/kg (2.4×104 - 4.8×104, and 9.6×104U/kg)( low, medium and high dose group) , such parameters as blood pressure, r
