研究人员发现佐料姜中一种天然存在的化合物:姜黄素与双特异性酪氨酸调节激酶2(DYRK2,生物通注)能在原子水平上结合。抑制癌症。

来自浙江大学生命科学研究院,北京大学,以及加州大学圣地亚哥分校的研究人员通过X射线晶体学和激酶抑制剂特异性分析,他们发现一种佐料姜中天然存在的化合物:姜黄素与双特异性酪氨酸调节激酶2(DYRK2,生物通注)能在原子水平上结合。

这种之前从未报道的姜黄素生物化学相互作用会抑制DYRK2,从而阻止细胞增殖并减轻癌症负担。这一研究发现公布在PNAS杂志上。

不过研究人员指出,单独使用姜黄素可能不是解决问题的办法。

因为一般来说,姜黄素很快被排出体外,如果姜黄素可以作为一种有效的药物,它需要进行修改才能进入血液,这样才能在体内停留足够长的时间,靶向癌症。而且由于姜黄素本身各种化学缺陷,可能不足以完全逆转癌症。

尽管姜黄素已经研究了250多年之久,之前也已经报道了其抗癌特性,但迄今为止还没有其它研究报道过姜黄素与蛋白激酶靶标结合的共晶结构。

激酶IKK和GSK3被认为是导致抗癌作用的主要姜黄素靶点,但最新研究中的姜黄素与DYRK2的共结晶结构,以及140-panel激酶抑制剂分析,表明姜黄素与DYRK2活性位点结合紧密,而后者的结合,其抑制水平比IKK或GSK3强500倍。

利用生化,小鼠癌症模型和细胞模型,研究小组发现姜黄素是DYRK2的选择性抑制剂,这种新型分子靶标不仅具有化学敏感性,而且具有蛋白酶体抑制剂抗性/适应性癌症的抗癌潜力。

“我们的结果揭示了姜黄素在DYRK2-蛋白酶体抑制中的意外作用,并提供了一个概念验证,即蛋白酶体调节剂的药理学操作可能为难以治疗的三阴性乳腺癌和多发性骨髓瘤治疗提供新的机会。我们的主要目标是开发一种能够在患有这些癌症的患者中靶向DYRK2的化合物”,文章通讯作者之一,浙江大学生命科学研究院郭行教授说。

DYRK2消化会影响蛋白酶体的活性,表现出较慢的癌症增殖速率,降低小鼠模型中的肿瘤大小。结合FDA批准的多发性骨髓瘤药物:carfilzomib,姜黄素能诱导了更高的癌细胞死亡率,而正常的非癌细胞受到的影响较小。

这表明将蛋白酶体调节剂(如DYRK2)与蛋白酶体抑制剂结合使用可能是一种有前景的抗癌治疗方法,副作用较小,但需要进一步研究。

Am J Geriatr Psychiatry:改善记忆力,调节情绪,多吃咖喱好处多多!

咖喱是一种原产于印度的香辛料,盛行于东南亚地区,主要由姜黄粉、胡椒、茴香等制成。冬天来一份热气腾腾的咖喱,不仅能增进食欲,还能促进血液循环,让手脚暖和。最近的一项研究显示,咖喱不光有这些好处,其中的姜黄素更有助于改善记忆力和调节情绪。

Interface Focus:姜黄素负载氧化石墨烯薄片可有效对抗耐甲氧西林金黄色葡萄球菌

耐甲氧西林金黄色葡萄球菌(MRSA)是全球造成严重医院感染的主要致病菌。姜黄素是姜黄的主要成分,可有效对抗MRSA,但仅在细胞毒素浓度下或与抗生素联合使用才可发挥此作用。基于姜黄素的治疗方法的所面临的主要问题是其溶解性差和高剂量时的细胞毒性大。 在本文中,我们描述了由姜黄素(Cu)和氧化石墨烯(GO)制成的复合纳米颗粒(GOCU)在MRSA感染治疗中的功效。GO是一种具有大表面积和高载药量的

Nanoscale:石墨烯负载姜黄素可有效对抗RSV感染

病毒引起的疾病仍然是一个全球性的负担。呼吸道合胞病毒(RSV)是婴幼儿下呼吸道疾病的主要病毒性病原体,与严重的肺部疾病的发生有关。在此基础上,我们开发了一种具有高效抗病毒活性的β-环糊精(CD)功能化氧化石墨烯(GO)复合材料,能有效地负载姜黄素。RSV是一种负性单链RNA病毒,以此为模型病毒研究多功能GO的抗病毒活性。经组织培养感染剂量试验和免疫荧光试验证实,负载姜黄素的功能化GO对RSV感染具

Disease Models Mech:被Nature泼冷水一年后,姜黄素研究又取得2项新成果

长期以来,姜黄素被认为具有疾病治疗潜能。虽然2017年1月,Nature杂志曾发文 “泼冷水”,但一些科学家似乎并没有放弃。时隔一年,两篇新论文于近期先后发表——科学家们不仅鉴定出了支持姜黄素发挥作用的关键基因,还证实了其能改善记忆力和情绪。

Int J Pharm Investig:姜黄素和奥硝唑凝胶治疗慢性牙周炎孰优孰劣

本研究旨在评估姜黄素和奥硝唑治疗慢性牙周炎的效果。 研究纳入了20名年龄在27至53岁之间的男性,诊断为慢性牙周炎,双侧均有探诊深度> 5mm的牙周袋。测量每名患者的菌斑指数、探诊深度和临床附着水平。患者接受完整的预防治疗,包括洁治和根面平整,之后将两种测试凝胶注射到两侧选定的两个实验位点,该位点探诊深度(PD)> 5mm,且对称。在第0天和第30天记录牙周袋PD,临床附着丧失和

Sci Rep:新型介孔支生物支架可明显改善骨组织再生

本研究中,研究人员制备了基于小麦醇溶蛋白(WG)/介孔硅酸镁(m-MCS)生物复合材料(WMC)的大孔介孔支架用于骨组织再生。实验分析显示,m-MCS用量的增加明显改善了WMC支架的介孔性和吸水性,同时稍微降低了其抗压强度。随着m-MCS含量的增加,WMC支架的降解能力明显增强,在Tris-HCl溶液中浸泡不同时间后,pH值的降低可以减缓。此外,随着m-MCS含量的增加,WMC支架在模拟体液(SB
