of the indoleamine 2,3-dioxygenase (IDO), a promising therapeutic target for anticancer immunotherapy, a series of 32 phenylthiosemicarbazide derivatives was prepared and their IDO inhibition evaluated. Our study demonstrated that among these derivatives, compound 14 characterized with a 4-cyanophenyl group on the thiosemicarbazide was the more potent IDO inhibitor in this series being endowed with an
为了探索硫代氨基脲化合物对抑制吲哚胺2,3-二加氧酶(IDO)的兴趣,IDA是抗癌免疫疗法的有希望的治疗靶标,制备了一系列32种苯基硫代氨基脲衍生物并评估了它们对IDO的抑制作用。我们的研究表明,在这些衍生物中,在硫代氨基脲上具有4-氰基苯基特征的化合物14是该系列中最有效的IDO抑制剂,具有IC 50为1.2μM。所描绘的SAR显示,相对于苯硫代氨基脲而言,在3-位和4-位的取代非常有前景,而在2-位的取代总是导致效力较低或无活性的衍生物。实际上,该研究突出了一种新颖有趣的IDO抑制支架,以进一步发展。
