The synthesis and characterization of a series of organometallic half-sandwich N,N-chelated iridium(III) complexes bearing a range of electron-donating and withdrawing substituents were described. The X-ray crystal structures of complexes 1, 3 and 5 have been determined. This work demonstrated how the aqueous chemistry, catalytic activity in converting coenzyme NADH to NAD+ and anticancer activity

coefficient: ∼0.7), damaged the integrity of the lysosomes, and induced apoptosis. The compounds could also decrease the mitochondrial membrane potential, catalyze the oxidation of the coenzyme (nicotinamide-adenine dinucleotide) and improve the levels of the intracellular reactive oxygen species, following an antitumormechanism of oxidation. Additionally, these compounds could block the metastasis of tumor

addition, the self-luminescence of the complex 1C was also successfully used in confocal microscopy images for elucidating the subcellularlocalization. Complex 1C specifically targeted to lysosomes in A549 cancer cells and caused lysosomal damages and promote cathepsin B released. Flow cytometry studies confirmed that the biological effects of this type of complexes induced apoptosis, especially late
achieved success in the development of anticancercomplexes. In this contribution, a series of organometallic half-sandwich iridium(III) complexes with various corresponding counteranions have been prepared and characterized. The size and coordination ability of the counteranions exert a great influence on the chemical reactivity and anticanceractivity of these complexes. The influence of the counteranions

F6 (Cpx = Cp*, tetramethyl(phenyl)cyclopentadienyl (Cpxph) or tetramethyl(biphenyl)cyclopentadienyl (Cpxbiph); N^N = diamine) have been synthesized and characterized. The molecular structure of 1A was determined using single‐crystal X‐ray diffraction analysis. The hydrolysis of 1A–5C was monitored using UV–visible spectra. Complexes 3A–3C showed catalytic activity for the oxidation of NADH to NAD+
十五有机金属铱(III)半夹心络合物(1A - 5C)具有通式[(η 5 -Cp X)IR(N ^ N)CL] PF 6(CP X =的Cp *,四甲基(苯基)环戊二烯基(已经合成并表征了Cp xph)或四甲基(联苯)环戊二烯基(Cp xbiph; N ^ N =二胺)。1A的分子结构使用单晶X射线衍射分析确定。1A – 5C的水解使用紫外可见光谱进行监测。配合物3A – 3C显示出将NADH氧化为NAD的催化活性+,其中3C在450分钟内显示最高的29.9营业额。在药物治疗24或48小时后,针对两种人类癌细胞系(HeLa和A549)进行了MTT分析的细胞毒性检查。该复合物显示出高效能,其中最有效的复合物(3C; IC 50 = 3.4μM)在暴露24小时后对A549细胞的活性是顺铂的六倍。随着Cp环上的苯基取代,对A549细胞的细胞毒性作用增强:Cp xbiph > Cp xph > Cp
