产品描述:
Birinapant not only binds to the isolated BIR3 domains of cIAP1, cIAP2, XIAP but the single BIR domain of ML-IAP with high affinity and degrades TRAF2-bound cIAP1 and cIAP2 rapidly accordingly inhibiting the activation of TNF-mediated NF- kB. Additionally, birinapantcan promote the formation of caspase-8: RIPK1 complex in response to TNF stimulation, which result in downstream caspasesactivation [4].In the inorganic SUM149- and SUM190-derived cells, which with differential XIAP expression (SUM149 wtXIAP, SUM190 shXIAP) and other high cIAP1/2 but low XIAP binding affinity bivalent Smac mimetic GT13402, XIAP inhibition are needed for increasing TRAIL potency. Opposite, single agent efficacy of Birinapant is owing to pan-IAP antagonism. Rapid cIAP1 degradation was caused by birinapant, as well as NF-κB activation, PARP cleavage andcaspase activation. While combined withTNF-α, showing strong combination activity, the combination was more effective than individual. The response in spheroid models was conserved, whereas in vivo birinapant inhibited tumor growth without adding TNF-α in vitro to resistant cell lines. In a parental cell line, TNF-αcombined withbirinapantinhibited the growth of a melanoma cell line with acquired resistance to the same extent of BRAF inhibition [1, 2].Drug treatment increased the mean [18F]ICMT-11 tumor uptake with a peak at 24 hours for CPA (40 mg/kg; AUC40-60: 8.04 ± 1.33 and 16.05 ± 3.35 %ID/mL × min at baseline and 24 hours, respectively) and 6 hours for birinapant (15 mg/kg; AUC40-60: 20.29 ± 0.82 and 31.07 ± 5.66 %ID/mL × min, at baseline and 6 hours, respectively). Voxel-based spatiotemporal analysis of tumor-intrinsic heterogeneity showed that [18F] ICMT-11 could detect the discrete pockets of caspase-3 activation. Caspase-3 activation that measured ex vivo associated with the increased tumor [18F] ICMT-11, and early radiotracer uptake predicted apoptosis, distinct from the glucose metabolism with [18F] fluorodeoxyglucose-PET, which depicted the continuous loss of cell viability [3].References:1.Allensworth JL, Sauer S, Lyerly HK, et al.

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。
