A series of RuII–arene complexes (1–6) of the general formula [(η6‐arene)Ru(L)Cl]PF6 (arene=benzene or p‐cymene; L=bidentate β‐carboline derivative, an indolealkaloid with potential cyclin‐dependent kinases (CDKs) inhibitory activities) is reported. All the complexes were fully characterized by classical analytical methods, and three were characterized by X‐ray crystallography. Hydrolytic studies
一系列的Ru II -arene复合物(1 - 6)通式[(η 6 -arene)的Ru(L)CL] PF 6(芳烃=苯或p -cymene; L =二齿β咔啉衍生物,吲哚生物碱具有潜在的细胞周期蛋白依赖性激酶(CDKs)抑制活性。所有配合物均已通过经典分析方法充分表征,其中三个已通过X射线晶体学表征。水解研究表明,β-咔啉配体在其水性行为中起着至关重要的作用。这些复合物在体外具有高活性,其中最活跃的复合物6与顺铂相比,对几种癌细胞的抗癌活性高3到12倍。有趣的是,该复合物能够克服对顺铂的交叉耐药性,并显示出对正常细胞的低得多的细胞毒性。配合物1 - 6可以直接靶向CDK1,因为它们可以在G2M期阻断细胞,下调CDK1和细胞周期蛋白B1的表达,并在体外抑制CDK1 /细胞周期蛋白B。进一步的机理研究表明,该复合物可通过线粒体相关途径和细胞内活性氧(ROS)升高有效诱导细胞凋亡。

This study demonstrates that the introduction of aromatic heterocyclic alkaloid ligands with a broad spectrum of biological activities and water-soluble aminoacidligands into copper
铜配合物长期以来被认为是一类有前途的抗癌或抗菌疗法。本文制备了两种含有β-咔啉衍生物和氨基酸的新型铜( II )配合物,即[Cu(1-Im-βc)( L -Val)]ClO 4 ·0.5H 2 O( Cu1 )和[Cu( 1-Im-βc)(L-Val)]ClO 4 ·0.5H 2 O(Cu1)。 (1-Im-βc)( L -Phe)]ClO 4 ·0.5H 2 O ( Cu2 ),其中 1-Im-βc = 1-(2-咪唑基)-β-咔啉,L -Val = L -缬氨酸,且L -Phe = L-苯丙氨酸,被设计和合成。通过元素分析、红外光谱、摩尔电导率测量和质谱分析对配合物进行表征,以确定其空间结构和组成。两种复合物均通过插入与 DNA 结合。该复合物还对人血清白蛋白 (HSA) 表现出良好的亲和力。此外,两种复合物对肺癌细胞(A549)、宫颈癌细胞(HeLa)和乳腺癌细胞(MBA-MD-23

Stimuli-activatable photosensitizers (PSs) are highly desirable for photodynamictherapy (PDT) to selectively demolish tumor cells. On the other hand, lysosomes are emerging as attractive anticancer targets. Herein, four cyclometalated iridium(III)–β-carboline complexes with pH-responsive singlet oxygen (1O2) production and lysosome-specific imaging properties have been designed and synthesized. Upon visible
对于光动力疗法(PDT)以选择性地破坏肿瘤细胞而言,刺激激活的光敏剂(PSs)是非常需要的。另一方面,溶酶体正在成为有吸引力的抗癌靶标。本文中,已设计并合成了四种具有pH响应单线态氧(1 O 2)产生和溶酶体特异性成像特性的环金属化铱(III)-β-咔啉配合物。在可见光(425 nm)照射下,它们显示出对癌细胞的高度选择性光毒性。值得注意的是,显示了络合物2([Ir(N ^ C)2(N ^ N)](PF 6),其中N ^ C = 2-苯基吡啶且N ^ N = 1-(2-苯并咪唑基)-β-咔啉)极高的光毒性指数(PI = IC50在黑暗/ IC 50的光)> 833抗人肺癌A549细胞。进一步的研究表明2介导的PDT通过溶酶体损伤诱导caspase依赖性凋亡。复合物2的pH响应磷光可用于监测PDT时的溶酶体完整性,这为就地监测治疗效果和实时评估治疗结果提供了可靠而方便的方法。我们的工作为通过
Synthesis and characterization of new fluorescent boro-β-carboline dyes
nominated this chemotype as a new fluorophore for the development of fluorescentprobes. As an example, diazaborinino-carbolines were used for the specific labeling of anti-Her2 antibody trastuzumab. The fluorescentconjugate showed a high fluorophore-antibody ratio and was confirmed as a useful tool for labeling and confocal microscopy imaging of tumour cells in vitro together with the ex vivo two-photon
