drugs, especially to treat multifactorial diseases such as cancer. The simultaneous regulation of multiple targets might represent an alternative synthetic approach to optimize patient compliance and tolerance, minimizing the risk of target-based drug resistance due to the modulation of a few targets. To this end, we conceived for the first time the design and synthesis of dual-ligands σR/HDACi to evaluate
设计和发现双靶点抑制剂化合物对于合成比单靶点药物更安全、更有效的新药物具有挑战性,特别是在治疗癌症等多因素疾病方面。同时调节多个靶点可能代表一种替代的合成方法,以优化患者的依从性和耐受性,最大限度地减少由于调节少数靶点而产生的基于靶点的耐药性的风险。为此,我们首次构想了双配体 σR/HDACi 的设计和合成,以评估作为解决这种复杂疾病的创新候选人的可能性。在针对几种肿瘤细胞系筛选的所有合成化合物中,化合物6(K i σ 1 R = 38 ± 3.7;K i σ 2 R = 2917 ± 769 和 HDAC IC 50 = 0.59 µM)是最有前途的抗增殖剂候选者。对 HCT116 细胞系的IC 50为 0.9 µM,对正常细胞无明显毒性。分子对接研究证实了 σ 1 R的亲和力和泛 HDAC 抑制行为,支持两个靶点之间可能存在平衡的亲和力和活性。
