上海华东师范大学易正芳团队近日的一项新研究报告称,抗疟化合物可抑制小鼠前列腺癌和肿瘤转移。相关成果12月14日凌晨发表于《自然—通讯》

前列腺癌的生长依赖雄性激素及其受体。临床试验表明,可阻断雄激素受体的药物是治疗前列腺癌的有效策略。但前列腺癌可能对这些药物表现出抵抗性,因为雄激素受体有替代表达形式,而目前的药物无法抑制它们。

为了寻找新型雄激素受体阻断剂,研究人员对自然化合物库进行了筛选,发现抗疟剂臭椿酮是可以阻断所有不同形式雄激素受体的有力抑制剂。在细胞和小鼠中,该药可抑制肿瘤细胞生长和肿瘤转移形成。事实上,该药与影响雄激素受体稳定性的蛋白质相互作用,导致肿瘤细胞内的受体降解。

研究者认为,可考虑使用该药治疗对现有疗法具有抵抗力的前列腺癌,而且它有助于推动未来进一步的研究和探索。

Nature:科学家筛选出一类新的抗疟疾药物二环吖丁啶

图片来自:www.sharenator.com 尽管根据世界卫生组织的数据,疟疾每年导致的死亡从2000年的84万到2015年已经降低到了44万,但是在热带地区(尤其是非洲地区),疟疾仍然给人们带来了无尽的苦难。因而开发出新的、廉价的抗疟疾药物对人类健康有着重大意义。 近期发表在Nature上的一篇文章,通过活体筛选的方法,发现了一类二环吖丁啶类小分子,对疟疾有着显著的效果,可能成为未
