Tirbanibulin (KX2-391, KX-01), a dual non-ATP (substrate site) Src kinase and tubulin-polymerization inhibitor, demonstrated a universal anti-cancer activity for variety of cancer types. The notion that KX2-391 is a highly selective Src kinase inhibitor have been challenged by recent reports on the activities of this drug against FLT3-ITD mutations in some leukemic cell lines. Therefore, we hypothesized
Tirbanibulin (KX2-391, KX-01) 是一种双重非 ATP(底物位点)Src 激酶和微管蛋白聚合抑制剂,对多种癌症类型表现出普遍的抗癌活性。KX2-391 是一种高选择性 Src 激酶抑制剂的观点受到了最近关于该药物对某些白血病细胞系中 FLT3-ITD 突变的活性的报道的挑战。因此,我们假设 KX2-391 的类似物可能抑制 Src 以外的致癌激酶。一组 4-芳酰基氨基苯基-ñ合成了-苄基乙酰胺,发现与实体瘤细胞系相比,它对白血病细胞系更有效。ñ-(4-(2-(苄基氨基)-2-氧代乙基)苯基)-4-氯苯甲酰胺(4e) 在 IC 50 0.96 µM、1.62 µM、1.90 µM 和 4.23 µM 下分别对 NB4、HL60、MV4-11 和 K562 白血病细胞系表现出活性。我们发现了潜在的机制4e不包括微管蛋白聚合或 Src 抑制。这些结果有趣地表明,KX2-391
