Nature & NCB:新型药物样化合物或可有效抑制癌症发展

近日,发表在国际杂志Nature和Nature Chemical Biology上的两项研究论文中,来自加拿大安大略省癌症研究所(Ontario Institute for Cancer Research)等机构的研究人员通过研究开发了一种名为OICR-9429的新型原型药,其或可促进研究者的相关研究;目前有研究者利用该药物研究研究表明,OICR-9429可以有效阻断乳腺癌细胞系的生长以及特殊白血病亚型细胞的生长。

通过制造药物样化合物,比如OICR-9429,就可以帮助研究者快速检测新型疗法的有效性以及相关研究结果的可用性,来自费城和维也纳的独立研究表明,OICR-9429的细胞靶点或许和新型药物发现有关。研究者Cheryl Arrowsmith教授指出,目前我们通常会采用协商的法律协议来向其他研究团体提供OICR-9429,而相关研究结果也表明该药物可以杀灭两种不同类型的癌细胞;研究者希望看到更多的利用OICR-9429进行的研究,而目前的方法对于进行早期药物开发也具有一定帮助。

OICR-9429会抑制一种名为WDR5的蛋白质,而最近有两项研究评估了OICR-9429对乳腺癌及白血病细胞系的效应,文章中研究者利用OICR-9429成功阻断了由p53基因突变驱动的乳腺癌细胞系的生长,然而在正常情况下p53是一种肿瘤抑制子,一旦其突变就会引发细胞功能失衡,尽管其会刺激WDR5的功能,但仍然会引发癌症发生。

由研究者Florian Grebien带领的研究小组研究中利用OICR-9429研究阐明了WDR5或许可以作为白血病的潜在治疗靶点,而OICR-9429可以阻断一系列白血病细胞的生长。最后研究者表示,OICR-9429仅仅是由研究者开发出了一种药物样化合物,其可以为科学家们提供一种进行早期药物开发的新途径,后期研究者还将继续进行深入研究来鉴别出其它的药物样特殊分子以加速癌症药物的开发。
