NG 52 是一种有效的,选择性的 ATP 兼容且具有口服活性的Cdc28p和Pho85p激酶抑制剂,IC50分别为 7 μM 和 2 μM。NG 52 还以IC50值为 2.5 μM 来抑制磷酸甘油酸激酶 1 (PGK1) 的活性。NG 52 对酵母激酶 Kin28p,Srb10 和 Cak1p 无活性。
生物活性 | NG 52 is a potent, cell-permeable, selective, ATP-compatible and orally activeCdc28pandPho85p kinaseinhibitor withIC50s of 7 μM and 2 μM, respectively. NG 52 also inhibits the activity ofphosphoglycerate kinase 1 (PGK1)with anIC50of 2.5 μM. NG 52 is inactive against yeast kinases Kin28p, Srb10, and Cak1p[1][2]. |

体外研究 (In Vitro) | NG 52 (Compound 52) inhibits growth in a drug-sensitized yeast strain (S. cerevisiae) with a GI50of 30 μM. NG 52 is active against cdc2-cyclin B with an IC50value of 340 nM[1]. NG 52 dose-dependently inhibits the proliferation of glioma U87 and U251 cell lines with GI50values of 7.8 μM and 5.2 μM, respectively, meanwhile it potently inhibits the proliferation of primary glioma cells[2]. NG 52 (12.5-50 μM) effectively inhibits the phosphorylation of PDHK1 at Thr338 site and the phosphorylation of PDH at Ser293 site in U87 and U251 cells, resulting in more pyruvic acid entering the Krebs cycle with increased production of ATP and ROS[2]. NG 52 can reverse the Warburg effect by enhancing the activity of pyruvate dehydrogenase (PDH) through inhibiting the activity of PGK1, and switched cellular glucose metabolism from anaerobic mode to aerobic mode[2].
