Chloroquine-d5 is intended for use as an internal standard for the quantification of chloroquine by GC- or LC-MS. Chloroquine is an aminoquinoline that is an inhibitor of autophagy and has antimalarial and anticancer activities.1,2,3 Chloroquine inhibits autophagosome-lysosome fusion in HeLa cells when used at a concentration of 100 μM.1 It is active against the chloroquine-sensitive GC03 strain of P. falciparum (IC50 = 29.2 nM) but has decreased activity against mutant pfcrt P. falciparum (IC50s = 100-150 nM).2 Chloroquine inhibits the growth of human SSC25 and CAL27 oral squamous cell carcinoma cells (IC50s = 29.9 and 17.3 μM, respectively), as well as A498, SN12C, RXF393, and 769-P renal cancer cells (IC50s = 16, 62, 81, and 25 μM, respectively).3,4 It reduces tumor growth in a CAL27 mouse xenograft model and a 4T1 mouse allograft model when administered at a dose of 50 mg/kg.3,5|1.

注意事项:
抗逆滴加序列
每次向板内滴加抗原时,移液器滴头要与平面45度悬空,不要触碰到孔内的液体,由后向前依次滴加(即浓度由低往高滴加)。
抗感染反应期
抗原抗体在室温20~25℃下,必须反应30min以上,若环境温度低于室温,可将微量反应板置于恒温培养箱中,使二者充分反应。
旅游温度
磷酸盐缓冲液的pH值要在高压灭菌后进行滴定,往往在高压后pH值会有所改变,所以高压后再调一次pH值更为准确。磷酸盐缓冲液一经使用保存期不要超过3周。当pH<5.8时,红细胞会产生自凝现象;当pH>7.8时,图形洗脱加快,易造成肉眼观察产生误差;p H=7.2时,红细胞沉降最充分,图形最清晰。
当滴注 1%红细胞悬液时,应经常摇晃红细胞悬液,使红细胞均匀地分布在磷酸缓冲液中,以防止红细胞下降。
反应时间及温度
加入鸡红血球之后,反应板在室温(20~25℃)静置30~40min,对照孔血球下沉于孔底,即可判定结果。若室温达不到实验要求,需相应调整反应时间。当环境温度低于4℃时,红细胞发生自凝;高于37℃时,会发生反应物分离和红细胞溶血。
使用方法:
1.本蛋白酶抑制剂混合物为100×的储存液,使用时按照1:100的比例加入到裂解液中(例如,1ml裂解液中加入10μl蛋白酶抑制剂混合物),混匀后即可使用。根据需要,0.5M的EDTA也按照1:100的比例加入到裂解液中(如用于检测金属蛋白酶活性,则不宜添加EDTA)。含有蛋白酶抑制剂混合物的裂解液宜现用现配,不宜配制后冻存待后续使用。
2. 待所需的抑制剂添加完毕混匀后,就可以开始进行哺乳动物组织的裂解和蛋白提取。

文献和实验亦称为三碳糖磷酸,是 3-磷酸甘油醛和二羟丙酮( dihydroxyacetone)磷酸的平衡混合物。 磷酸丙糖异构酶参与此平衡反应。在糖酵解的过程中,由 1, 6- 二磷酸果糖经醛缩酶( aldolase)的作用解裂生成,通过 3- 磷酸甘油醛 - 脱氢酶( dehyd- rogenase)能可逆的被磷酸化和氧化而产生 1, 3-二磷酸甘油酸。也可以作为光合成过程(还原型戊糖磷酸循环)的中间产物而生成。
磷酸原之一。是 P. Eggle- ton和 G. P. Eggleton( 1927) 首先从猫的肌肉中发现的,它广泛地存在于脊椎动物的肌肉中。为无色水溶性,其钠盐、钙盐也可溶于水。具有高能磷酸键(Δ G°′ = - 10.3千卡)在酸性溶液中,易分解成肌酸与正磷酸,在中性溶液中,比较稳定。在生物体内由肌酸和 ATP经酶的作用合成,但反应是可逆的,呈如下的平衡(称为肌酸激酶反应,过去称为 Lohmann反应):
Antibody-Bearing Liposomes as Chloroquine Vehicles in Treatment of Murine Malaria
because the malarial parasites are rapidly developing resistance to the existing antimalarial drugs, like chloroquine (2 ), when given in classical pharmaceutical forms. Studies on the molecular basis of chloroquine resistance suggest that enhanced active efflux
