Product Introduction
Bioactivity
| 名称 | IPA-3 |
| 描述 | IPA-3 is a selective non-ATP competitive Pak1 inhibitor with IC50 of 2.5 μM, no inhibition to group II PAKs (PAKs 4-6). |
| 细胞实验 | Human primary schwannoma cells are grown on 96 well plates for 2 days. Cells are left untreated or treated with 5 μM IPA-3, 20 μM IPA-3 or 20 μM PIR-3.5 for 24 hours. The MTS-solution is left on the cells for 3 hours, before the absorbance at 490 nm is measured. The experiments are conducted three times and mean and standard error of the mean is calculated with Excel. |
| 激酶实验 | Pak1 (150 nM final) is pre-incubated with MBP (8.3 μM), indicated proteins, and IPA-3 or DMSO in Kinase buffer for 20 minutes at 4°C. Cdc42-GTPγS (3.2 μM) is then added and the reaction is pre-equilibrated 10 minutes at 30°C. Kinase reactions are started by the addition of ATP (to 30 μM) containing [32P]ATP and are incubated 10 min and analyzed by SDS-PAGE and autoradiography. |
| 体外活性 | IPA-3是一种非ATP竞争性的、异构体抑制剂,针对p21激活的蛋白激酶1 (Pak1)。PIR3.5作为IPA-3的对照化合物。IPA-3阻止由Cdc42刺激的Pak1在Thr423上的自磷酸化。同时,IPA-3也阻断了鞘氨醇依赖的Pak1自磷酸化,并且不针对Pak1上的裸露半胱氨酸残基。IPA-3的二硫键对于抑制Pak1至关重要,还原剂二硫苏糖醇(DTT)通过体外还原作用消除了IPA-3对Pak1的抑制。IPA-3能抑制多种激活剂引发的Pak1活化,但不影响已经激活的Pak1。在小鼠胚胎成纤维细胞中,IPA-3抑制了由PDGF触发的Pak激活。[1] IPA-3部分通过与Pak1调节域的共价结合来抑制Pak1的活化。IPA-3在特定时间和温度下与Pak1形成共价结合,阻断Pak1激活剂Cdc42的结合,并直接与Pak1自调节域结合。IPA-3可逆地抑制PMA诱导的细胞膜皱褶形成。[2] |

文献和实验网络 第十九章 杂环化合物和生物碱 杂环化合物在自然界分布很广,其数量几乎占已知有机化合物的三分之一,用途也很多。许多重要的物质如叶绿素、血红素、核酸以及临床应用的一些有显著疗效的天然药物和合成药物等,都含有杂环化合物的结构。生物碱多是中草药的有效成分,绝大多数是含氮的杂环化合物。本章内容与医学关系密切,具有重要意义。
分子中具有高能键的化合物。在生物体内主要有上式(Ⅰ)和(Ⅱ)两种结构的高能化合物。其作用为贮藏能量(例如 ATP、肌酸磷酸)和作为产生 ATP源的中间代谢产物(例如磷酸烯醇丙酮酸)以及合成反应的中间物质(例如酰基辅酶 A),在蛋白质的结构( conformation)变化周期的第一阶段上(例如钠钾 ATP酶的羧基磷酸中间体)也具有重要作用。多数高等化合物具有磷酸基,但也有例外。
由不同种元素组成的纯净物叫做化合物。化合物一般有固定的组成。化合物的组成一般可用化学式表示。化合物具有确定的物理性质和化学性质,不同于其组成元素的性质。化合物中的元素不能用简单的机械方法或物理方法分开,而必须用化学方法才能分离。
