Aiming to control neurite formation and navigate the axonal growth by an extrinsic guidance, we report on the design, synthesis and biological evaluation of caged retinoids. Agonists of RARβ have been temporarily blocked either by the [(α-methyl-2-nitropiperonyl)oxy]carbonyl (MeNPOC) group or by immobilization using nitrocatechol linkers on TiO2 particles. Release on demand has been achieved by release under UV irradiation, leading to the biologically active compounds, which have been shown to induce neuronal differentiation and neurite outgrowth.
为了通过外在指导控制神经突形成并引导轴突生长,我们报告了笼状视黄醇的设计、合成和生物学评价。 RARβ 激动剂已被 [(α-甲基-2-硝基胡椒基) 氧基]羰基 (MeNPOC) 基团或通过使用 TiO2 颗粒上的硝基儿茶酚连接体固定而暂时阻断。通过在紫外线照射下释放来实现按需释放,从而产生生物活性化合物,这些化合物已被证明可以诱导神经元分化和神经突生长。
