hVEGF-IN-1  纯度: 98.56%

hVEGF-IN-1，一种喹唑啉衍生物，可以特异性结合内部核糖体进入位点 A (IRES-A) 中富含 G 的序列，并会使 G-四链体结构不稳定。在 SPR 实验中，hVEGF-IN-1 以 0.928 μM 的 Kd 值与 IRES-A (WT) 结合。hVEGF-IN-1 可通过降低 VEGF-A 蛋白表达来阻止肿瘤细胞迁移并抑制肿瘤生长。

生物活性

hVEGF-IN-1, a quinazoline derivative, could specifically bind to the G-rich sequence in the internal ribosome entry site A (IRES-A) and destabilize the G-quadruplex structure. hVEGF-IN-1 binds to the IRES-A (WT) with a Kd of 0.928 μM in SPR experiments. hVEGF-IN-1 could hinder tumor cells migration and repress tumor growth by decreasing VEGF-A protein expression[1].

体外研究
(In Vitro)

hVEGF-IN-1 (compound 1) (1 nM-100 μM; 5 min) binds to IRES-A (WT) and IRES-A mutant RNA oligomer (IRES-MU1) with Kds of 1.29 and 13.4 μM by microscale thermophoresis (MST) measurements, respectively[1].
hVEGF-IN-1 (0.375-3 μM; 0-24 h) reduces MDA-MB-231 cell migration approximately 25% at the concentration of 3 μM[1].
hVEGF-IN-1 (0.1875-3 μM; 48 h) reduces the level of VEGF-A protein in MCF-7 cells[1].
hVEGF-IN-1 (0.375-3 μM; 48 h) decreases the relative wound closure of migrated MCF-7 cells by ∼35% at the concentration of 3 μM[1].
hVEGF-IN-1 (1.25-10 μM) reduces the stability of the IRES-A G-Quadruplex in a dose-dependent manner[1].
