Our research group showed that E-salignone inhibited the invasion of human breast cancer MDA-MB-231 cells induced by the chemokine epidermal growth factor (EGF). Due to the limited natural resources, we had to prepare sizable quantities of E-salignone for the antimetastasis investigation. E-Salignone was synthesized by methylation of the corresponding amine by reductive amination with paraformaldehyde in the presence of sodium triacetoxyhydroborate. The synthesized E-salignone exhibited significant inhibitory effects on the invasion of human MDA-MB-231 breast cancer cells and non-small cell lung cancer cells (A549) induced by the chemokine EGF with IC50 values of 0.36 μM and 5.77 μM, respectively. Since angiogenesis is required for tumor metastasis, anti-angiogenesis is consider a promising approach for tumor therapy. In our investigation of antimetastatic activity, E-salignone potently inhibited the migration of HUVEC and MDA-MB-231 in the wound healing assay.
我们的研究小组显示,E-salignone抑制了由
趋化因子表皮生长因子(
EGF)诱导的人乳腺癌
MDA-MB-231细胞的侵袭。由于自然资源有限,我们不得不为抗转移研究制备大量E-salignone。E-salignone是通过在
三乙酸钠氢
硼酸钠存在下,采用还原胺化法对相应胺进行甲基化合成的。合成的E-salignone对由
趋化因子EGF诱导的人
MDA-MB-231乳腺癌细胞和非小细胞肺癌细胞(A549)的侵袭表现出显著的抑制作用,IC50值分别为0.36 μM和5.77 μM。由于肿瘤转移需要血管生成,抗血管生成被认为是肿瘤治疗的一种有前景的方法。在我们对抗转移活性的研究中,E-salignone在伤口愈合实验中强效抑制了HU
VEC和
MDA-MB-231的迁移。
