产品描述:
Cidofovir is an anti-CMV drug which can suppress CMV replication by selective inhibition of viral DNA polymerase and therefore prevention of viral replication and transcription.IC50 Value:Target: CMV DNA polymerasein vitro: The minimum concentrations of (S)-HPMPC required to inhibit CMV plaque formation by 50% was microgram/ml. The selectivity indices of (S)-HPMPC, as determined by the ratio of the 50% inhibitory concentration for cell growth to the 50% inhibitory concentration for plaque formation for CMV (AD-169 strain), was 1,500 [1]. The time course of uptake of HPMPC into Vero cells was linear between 10 and 75 min and proportional to the concentration in the medium from 10(-6) to 10(-2) M. HPMPC uptake was temperature sensitive and the rate of uptake was considerably lower at 27 degrees than at 37 degrees and almost totally inhibited at 4 degrees [2]. in vivo: Levels of cidofovirin serum following intravenous infusion were dose proportional over the dose range of 1.0 to 10.0 mg/kg of body weight and declined biexponentially with an overall mean +/- standard deviation terminal half-life of 2.6 +/- 1.2 h (n = 25). Approximately 90% of the intravenous dose was recovered unchanged in the urine in 24 h. The overall mean +/- standard deviation total clearance of the drug from serum (148 +/- 25 ml/h/kg; n = 25) approximated renal clearance (129 +/- 42 ml/h/kg; n = 25), which was significantly higher (P < 0.001) than the baseline creatinine clearance in the same patients (83 +/- 21 ml/h/kg; n = 12) [3]. Positive CMV urine cultures reverted to negative in 2 of 8 patients receiving doses of < or = 1.5 mg/kg twice weekly and 11 of 13 patients receiving higher doses. Cidofovir has in vivo anti-CMV activity demonstrated by prolonged clearing of CMV viruria, although this orvation is tempered by the fact that clearance of viremia could not be demonstrated [4].Toxicity: Patients receiving 0.5 or 1.5 mg/kg twice weekly experienced no serious toxicity. The first two patients who received 5 mg/kg twice weekly developed glycosuria and 2+ proteinuria. Suquent patients received concomitant probenecid to attempt to ameliorate renal toxicity [4].Clinical trial: FDA approved drug
使用方法:
1. 常用筛选浓度
注意：用来筛选稳转株的工作浓度需要根据细胞类型，培养基，生长条件和细胞代谢率而变化，推荐使用浓度为50-1000μg/mL。对于第一次使用的实验体系建议通过建立杀灭曲线(kill curve)，即剂量反应性曲线，来确定最佳筛选浓度。
一般而言，哺乳动物细胞50-500μg/mL;细菌/植物细胞20-200μg/mL;真菌300-1000μg/mL。
2. 杀灭曲线的建立
注意：为了筛选得到稳定表达目的蛋白的细胞株，需要确定能够杀死未转染宿主细胞的抗生素浓度，可通过建立杀灭曲线(剂量反应曲线)来实现，至少选择5个浓度。
1) 第一天：未转化的细胞按照20-25%的细胞密度铺在合适的培养板上，37℃，CO2培养过夜;注：对于需要更高密度来检测活力的细胞，可增加接种量。
2) 根据细胞类型，设定合适范围内的浓度梯度。以哺乳动物细胞为例，可设定50，100，250，500，750，1000μg/mL。先用去离子水或者PBS buffer按照1:10的比例将母液稀释到5 mg/ml，然后按照下表稀释到相应浓度的工作液。
3) 第二天：替换旧的培养基，换用新鲜配制的含有相应浓度药物的培养基。每个浓度做三个平行孔。
4) 接下来每3-4天更换新的含药物培养基。
5) 按照固定的周期(如每2天)进行活细胞计数来确定阻止未转染细胞生长的恰当浓度。选择在理想的天数(通常是7-10天)内能够杀死绝大多数细胞的浓度为稳定转染细胞筛选用的工作浓度。
3. 稳定转染细胞的筛选
1) 转染48h后，用含有适当浓度的潮霉素B筛选培养基来传代细胞(直接传代或者稀释后传代)。
注意：细胞处于活跃分裂状态时抗生素的杀伤。则当细胞过于稠密，其效率会降低。为了得到较好的筛选效果，最好将细胞稀释至丰度不超过25%
2) 每隔3-4天更换含有药物的筛选培养液。
3) 筛选7天后观察并评估细胞克隆(集落)的形成情况。集落的形成可能还需要一周或者更多的时间，这取决于宿主细胞类型，转染，以及筛选效果。
4) 挑取并转移5-10个抗性克隆于35mm细胞培养板，继续用含药物的筛选培养液维持培养7天。
5) 之后更换正常培养基培养即可。
