With the aim of finding a better kidney-type glutaminase (KGA) inhibitor with potential anti-cancer properties, 18 nor-oleanane triterpenoids from Stauntonia brachyanthera, including 2 new ones, were screened against KGA. The structure-based virtual ligand screening identified 8 compounds, which might have more chance to become inhibitors of KGA with low binding energy. Glutaminase inhibition experiments
为了找到一种更好的具有潜在抗癌特性的肾脏型谷氨酰胺酶(KGA)抑制剂,筛选了18种来自苦参(Stauntonia brachyanthera)的正戊烷三萜类化合物,其中包括2种新的抗萜烯类抗KGA。基于结构的虚拟配体筛选可鉴定出8种化合物,这些化合物可能更有机会成为具有低结合能的KGA抑制剂。谷氨酰胺酶抑制实验和一系列细胞水平的测定,包括细胞毒性,伤口愈合,穿透孔侵袭,蛋白质印迹和细胞凋亡,进一步证实了5(brachyantheraoside A 8)的抑制作用。这些提供了5成为抑制剂的可能性。
