抑制剂描述: 产品名称:IPA-3 产品别名:见爱必信官网 英文别名:IPA-3 靶点:PAK CAS:42521-82-4 纯度:>98% 外观:见爱必信官网 保存方法:Store at -20℃ for one year(Powder);Store at 2-4℃ for two weeks;Store at -20℃ for six months after dissolution. 描述: IPA-3是非ATP竞争的PAK1选择性抑制剂,IC50为2.5 μM,对于II型 PAKs (PAKs 4-6)无抑制活性。 溶解性:DMSO : 65 mg/mL (185.5 mM) 体外研究: IPA-3 inhibits Pak1 activation in part by binding covalently to the regulatory domain of Pak1. IPA-3 binds Pak1 covalently in a time- and temperature-dependent manner. IPA-3 prevents binding of the Pak1 activator Cdc42. IPA-3 binds directly to the Pak1 autoregulatory domain. IPA-3 reversibly inhibits PMA-induced membrane ruffling in cells. IPA-3 (2 µM, 5 µM or 20 µM) reduces cell spreading in human primary Schwann and schwannoma cells. IPA-3 treatment significantly reduces the number of adherent Schwann and schwannoma cells in a dose-dependent manner. IPA-3 is a non ATP-competitive, allosteric inhibitor of p21-activated kinase 1 (Pak1). PIR3.5 is the control compound of IPA-3. IPA-3 prevents Cdc42-stimulated Pak1 autophosphorylation on Thr423. IPA-3 also prevents sphingosine-dependent Pak1 autophosphorylation. IPA-3 does not target exposed cysteine residues on Pak1. The disulfide bond of IPA-3 is critical for inhibition of Pak1 and in vitro reduction by the reducing agent dithiothreitol (DTT) abolishes Pak1 inhibition by IPA-3. IPA-3 inhibits activation of Pak1 by diverse activators, but does not inhibit preactivated Pak1. IPA-3 inhibits PDGF-stimulated Pak activation in mouse embryonic fibroblasts. 体内研究:

使细胞中8-OXO-dGTP浓度增高,A→C的突变几率增大,有利于利用点突变进行基因改造。dut (dUTPase)Map position: 82 min功能:dut基因表达脱氧尿嘧啶三磷酸核苷酸水解酶(dUTPase),它能水解dUTP成为dUMP,使细胞体内dUTP的浓度维持在较低的水平,尿嘧啶(U)就不易掺入到DNA中,避免了基因发生A→U的突变。dut基因发生突变使dUTPase活性缺失,导致dUTP浓度升高,碱基U(尿嘧啶)极易掺入到DNA中,使其发生A→U的基因突变,有利于利用点突变
