Vimentin-IN-1 是 FiVe1 衍生物,是一种口服有效的选择性抗癌剂。FiVe1 能够结合 III 型中间丝蛋白 vimentin (VIM),诱导 Ser56 过度磷酸化,导致有丝分裂的选择性中断和转化表达 VIM 的间充质癌细胞的多核化。Vimentin-IN-1 比 FiVe1 表现出更好的口服利用度和药代动力学特征。
生物活性
Vimentin-IN-1 is a FiVe1 derivative, an orally active and selective anticancer agent. FiVe1 binds type III intermediate filament protein vimentin (VIM), to induce hyperphosphorylation of Ser56, resulting selective disruption of mitosis and multinucleation in transformed VIM-expressing mesenchymal cancer cells. Vimentin-IN-1 shows better oral bioavailability and pharmacokinetic profiles than FiVe1.

体外研究(In Vitro)
Vimentin-IN-1 (compound 4e) (0-10 mM; 72 h) inhibits a marked improvement in potency with an IC50 value of 44 nM against HT-1080 fibrosarcoma, better than than FiVe1 (IC50=1.6 μM, HT-1080).Vimentin-IN-1 (0.1 μM; 24 h) induces phosphorylation of VIM at Ser56.Vimentin-IN-1 (100 μM; sampled at 0, 5, 15, 30, 45, and 60 min) exhibits poor stability with 0.0% remaining after 60 min of incubation in mouse liver microsome. has not independently confirmed the accuracy of these methods. They are for reference only.
体内研究(In Vivo)
Vimentin-IN-1 (compound 4e) (10 mg/kg; p.o.; single dose) shows better oral pharmacokinetic properties than Five1.
