A-674563 is a potent and selective Akt1 inhibitor with IC50 value of 14 nM. A-67453 also inhibited PKA and Cdk2 with IC50 value of 16 nM and 46 nM.
Akt, also known as protein kinase B, is a serine/threonine-specific protein kinase that plays a key role in multiple cellular processes such as glucose metabolism, apoptosis, cell proliferation, transcription and cell migration.
In MiaPaCa-2 cells treated with A-674563 for 48 hour, it slowed the tumor cell proliferation (EC50 = 0.4 μm). In STS cells, phosphorylation of GSK3 and MDM2 was prominently reduced by A-674563 treatment. [1] Akt inhibition-induced G2 cells cycle arrest and apoptosis were also observed in A563-treated STS cells. [2]
In scid mice carrying established PC-3 tumors, administration of A-674563 at 40 mg/kg per day for 21 days, combined with administration of paclitaxel at 15 mg/kg per day on days 20.24.28, increased the efficacy of paclitaxel compared with paclitaxel monotherapy. [1] A563 also significantly blocked HT1080 xenograft growth in nude mice. [2]

碳酸氢钠溶液是一种co2缓冲液,当瓶内二氧化碳量减少时,碳酸氢钠溶液释放co2,反之吸收co2.因此它能保持瓶内二氧化碳量大致不变.
求采纳为满意回答。
1、 缓冲溶液对反应物的测定没有干扰
2、缓冲组分的浓度为1:1
3、有足够的缓冲容量
4、缓冲溶液的PH应在所需范围内
5、组成缓冲溶液的弱碱PKB和弱酸PKA应接近或等于所需的POH值或PH值（PH+POH=14）
配制
只要知道缓冲对的PH值，和要配制的缓冲液的pH值（及要求的缓冲液总浓度），就能按公式计算[盐]和[酸]的量。这个算法涉及对数换算，较麻烦，前人为减少后人的计算麻烦，已为我们总结出pH值与缓冲液对离子用量的关系并列出了表格。只要我们知道要配制的缓冲液的pH，经查表便可计算出所用缓冲剂的比例和用量。例如配制500nmpH5.8浓度为0.1M磷酸缓冲液。
经查表知pH5.8浓度为0.2M Na2HPO48.0毫升，而0.2M Na2HPO492.0毫升。依此可推论出配制100ml0.1M的磷酸缓冲液需要0.1M Na2HPO48.0毫升，而0.1M Na2HPO4需要92.0毫升。
计算好后，按计算结果准确称好固态化学成分，放于烧杯中，加少量蒸馏水溶解，转移入50ml容量瓶，加蒸馏水至刻度，摇匀，就能得到所需的缓冲液。
各种缓冲溶液的配制，均按表格按比例混合，某些试剂，必须标定配成准确浓度才能进行，如醋酸、氢氧化钠等。另外，所有缓冲溶剂的配制计量都能从以上的算式准确获得。
