A new series of Vinpocetine derivatives were synthesized and evaluated for their inhibitory activity on PDE1A in vitro. Seven compounds with higher inhibitory activity were selected for surface plasmon resonance (SPR) binding experiments. Compared with Vinpocetine, these high potency compounds presented a higher binding affinity with PDE1A, which was consistent with inhibitory activity. After further
合成了一系列新的长春西汀衍生物,并对其在体外对PDE1A的抑制活性进行了评估。选择了七种具有较高抑制活性的化合物进行表面等离振子共振(SPR)结合实验。与长春西汀相比,这些高效化合物与PDE1A的结合亲和力更高,这与抑制活性是一致的。经过进一步筛选后,选择化合物5、7、21、34和长春西汀来检查血管舒张剂对内皮完好的大鼠胸主动脉环的作用。研究表明,在浓度为100μM时,化合物7和21的影响最为显着,最大值分别为93.46±0.77%和92.90±0.78%(n = 5)。基于这些研究,化合物7和21被认为可以进一步发展为命中化合物。
