metastases development in vivo. Until now, very few specific blockers of Orai1 and/or SK3 have been developed as potential anti-metastatic compounds. In this study, we illustrated the synthesis of new families of lipophilic pyridine and tetrahydropyridine derivatives designed as potential modulators of SK3 channel. The toxicity of the newly synthesized compounds and their migration effects were evaluated
现在证明小电导钙 (Ca2+) 激活钾 (K+) 通道 (SKCa) 参与许多癌细胞行为,例如增殖或迁移。 SK3 通道亚型在乳腺癌中得到了特别描述,它可以与 Orai1 Ca2+ 通道结合形成复合物,在肿瘤发育过程中调节 Ca2+ 稳态,并充当体内骨转移发展的有效介质。到目前为止,很少有 Orai1 和/或 SK3 的特异性阻断剂被开发为潜在的抗转移化合物。在这项研究中,我们阐述了亲脂性吡啶和四氢吡啶衍生物新家族的合成,这些衍生物被设计为 SK3 通道的潜在调节剂。在乳腺癌细胞系 MDA-MB-435s 上评估了新合成化合物的毒性及其迁移效应。两种分子(7a 和 10c)显示 SK3 通道依赖性迁移以及 SK3/Orai1 相关的 Ca2+ 进入显着减少。目前的测量表明,这些化合物更有可能具有 SK3 选择性。总而言之,这些结果表明此类分子可被视为有前途的乳腺癌抗转移药物。
