New series of thiazolyl-pyrazoline derivatives (, and ) have been synthesised and assessed for their potential EGFR and VEGFR-2 inhibitory activities. Compounds and exerted potent and selective inhibitory activity towards the two receptor tyrosine kinases; EGFR (IC = 40.7 ± 1.0 and 32.5 ± 2.2 nM, respectively) and VEGFR-2 (IC = 78.4 ± 1.5 and 43.0 ± 2.4 nM, respectively). The best anti-proliferative activity for the examined thiazolyl-pyrazolines was observed against the non-small lung cancer cells (NSCLC). Compounds and displayed pronounced efficacy against A549 (IC = 4.2 and 2.9 µM, respectively) and H441 cell lines (IC = 4.8 and 3.8 µM, respectively). Moreover, our results indicated that and were much more effective towards EGFR-mutated NSCLC cell lines (NCI-H1650 and NCI-H1975 cells) than gefitinib. Finally, compounds and induce G2/M cell cycle arrest and apoptosis and inhibit migration in A549 cancerous cells.
新系列的噻唑基-吡唑啉衍生物(、和)已经被合成,并评估了它们对 EGFR 和 VEGFR-2 的潜在抑制活性。化合物和对两种受体酪氨酸激酶具有强大而选择性的抑制活性;EGFR(IC = 40.7 ± 1.0 和 32.5 ± 2.2 nM,分别)和 VEGFR-2(IC = 78.4 ± 1.5 和 43.0 ± 2.4 nM,分别)。在所检查的噻唑基-吡唑啉中,对非小细胞肺癌细胞(NSCLC)的抗增殖活性最好。化合物和对 A549(IC = 4.2 和 2.9 μM,分别)和 H441 细胞系(IC = 4.8 和 3.8 μM,分别)表现出明显的疗效。此外,我们的结果表明,和对 EGFR 突变型 NSCLC 细胞系(NCI-H1650 和 NCI-H1975 细胞)的疗效比吉非替尼更显著。最后,化合物和诱导 A549 癌细胞的 G2/M 细胞周期停滞和凋亡,并抑制迁移。
