草酸钠作为 PDK1 和 LDHA 抑制剂，IC50 值 (μg/mL) 为 15.60。
Cas No.:565-73-1
Sample solution is provided at 25 µL, 10mM.
Sodium oxamate as PDK1 and LDHA inhibitor with IC50 values (μg/mL) of 15.60[1]. Sodium oxamate can specifically inhibit LDH-A. Sodium oxamate by down-regulating CDK1/cyclin B1 Pathway induces G2/M cell cycle arrest and promotes apoptotic targets by increasing ROS production in mitochondria[4,5].
Sodium oxamate enhances the suppressive effects of PARP inhibitors on ovarian cancer without BRCA mutations, remarkably promoting the inhibitory effects of PARP inhibitors on wild-type BRCA ovarian cancer cells[3]. In the human PC cell line, Sodium oxamate caused cell inhibition, resulting in increased sensitivity of CRPC cells to DOC, and the combination of DOC and Sodium oxamate promoted apoptosis compared with DOC or Sodium oxamate alone[2].
Sodium oxamate reduces the growth of colorectal cancer in CRC mice, by restoring the down-regulated MMR functional proteins and attenuating chemotherapy resistance to oxaliplatin caused by C. tropicalis[6]. NETosis and lactate accumulation during LPS induced sepsis in mice was inhibited by sodium oxamate [7].

草酸钠作为 PDK1 和 LDHA 抑制剂,IC50 值 (μg/mL) 为 15.60[1]。草酸钠可以特异性抑制LDH-A。草酸钠通过下调 CDK1/cyclin B1 通路诱导 G2/M 细胞周期停滞,并通过增加线粒体中 ROS 的产生促进凋亡靶点[4,5]。
草酸钠增强PARP抑制剂对无BRCA突变卵巢癌的抑制作用,显着促进PARP抑制剂对野生型BRCA卵巢癌细胞的抑制作用[3]。在人 PC 细胞系中,草酸钠引起细胞抑制,导致 CRPC 细胞对 DOC 的敏感性增加,与单独使用 DOC 或草酸钠相比,DOC 和草酸钠联合促进细胞凋亡[2] .
草酸钠通过恢复下调的 MMR 功能蛋白和减弱由热带念珠菌引起的对奥沙利铂的化疗耐药性来减少 CRC 小鼠结直肠癌的生长[6]。草胺酸钠可抑制 LPS 诱导小鼠脓毒症期间的 NETosis 和乳酸积累[7]。
