cells. Furthermore, the lead compound 15a could also antagonize the activation of STAT3 induced by HDACs inhibition in some breast cancer cells, which further reduced the level of pro-survive proteins in tumor cells and enhanced anti-tumor activity regulated by STAT3 signaling in vivo. Overall, our findings demonstrated that the novel compound 15a might be a HDACs inhibitor candidate, which could be
组蛋白脱乙酰基酶(HDACs)抑制剂已在血液系统恶性肿瘤中显示出巨大的临床成就。然而,由于复杂的肿瘤微环境,HDACs抑制剂治疗实体瘤的功效仍然受到限制。在这项研究中,我们基于黄酮和异黄酮的结构设计并合成了一类新型的HDACs抑制剂,然后进行生物学评估。具体而言,发现了一种铅化合物15a,其对多种实体瘤细胞具有强烈的抗增殖作用,特别是对于具有SAHA抗性的乳腺癌细胞。研究表明15a可以显着抑制HDAC 1,2,3(I类)和6(IIB类)的活性,导致乙酰化组蛋白和α-肾上腺素的剂量依赖性积累,细胞周期阻滞(G1 / S期)和细胞凋亡。乳腺癌细胞。此外,铅化合物15a还可以拮抗HDACs抑制作用在某些乳腺癌细胞中诱导的STAT3激活,从而进一步降低肿瘤细胞中前生存蛋白的水平,并增强体内STAT3信号传导调节的抗肿瘤活性。总体而言,我们的发现表明,新型化合物15a可能是HDACs抑制剂的候选物,可以用作乳腺癌的有前途的化学治疗剂。
