《A lysosome-targeted ruthenium(II) polypyridyl complex as photodynamic anticancer agent》 was written by Chen, Jun; Tao, Qin; Wu, Jian; Wang, Mengmeng; Su, Zhi; Qian, Yong; Yu, Tao; Wang, Yan; Xue, Xuling; Liu, Hong-Ke. SDS of cas: 1134-35-6 And the article was included in Journal of Inorganic Biochemistry in 2020. The article conveys some information:

Polypyridyl ruthenium complexes as novel photosensitizers had drawn attention due to its high selectivity towards cancer cells and low toxicity to normal cells. Herein, we synthesized a lysosome-targeted polypyridyl ruthenium complex Rhein-Ru(bpy)3 (bpy = 2,2′-bipyridine, rhein = 4,5-dihydroxy-9,10-dioxoanthracene-2-carboxylic acid), tethering with the Chinese medicine herb rhein. Rhein-Ru(bpy)3 exhibited high phototoxicity with short time of irradiation against tumor cell lines with the IC50 value of 2.4- 8.7 μM, and higher cytotoxicity against cisplatin-resistant A2780 cell lines, suggesting that Rhein-Ru(bpy)3 could overcome the cisplatin resistance. Moreover, Rhein-Ru(bpy)3 displayed low cytotoxicity towards cell lines in dark incubation, which was beneficial to reduce the toxic side effects towards normal cell lines. Besides, the confocal imaging and western blotting assay results suggested that Rhein-Ru(bpy)3 could induce cancer cell death through the autophagy pathway. These results inspired us that lysosome-targeted photosensitizers based on ruthenium complexes showed great potential for photodynamic therapy (PDT) application in cancer treatment.

《Proton-Coupled Electron Transfer for Photoinduced Generation of Two-Electron Reduced Species of Quinone》 was written by Dey, Ananta; Ghorai, Nandan; Das, Amitava; Ghosh, Hirendra N.. Computed Properties of C12H12N2 And the article was included in Journal of Physical Chemistry B in 2020. The article conveys some information:

Purpose-built mols. that follow the fundamental process of photosynthesis have significance in developing better insight into the natural photosynthesis process. Quinones have a significant role as electron acceptors in natural photosynthesis, and their reduction is assisted through H-bond donation or protonation. The major challenge in such studies is to couple the multielectron and proton-transfer process and to achieve a reasonably stable charge-separated state for the elucidation of the mechanistic pathway. We have tried to address this issue through the design of a donor-acceptor-donor mol. triad (2RuAQ) derived from two equivalent [Ru(bpy)3]2+ derivatives and a bridging anthraquinone moiety (AQ). Photoinduced proton-coupled electron transfer (PCET) for this mol. triad was systematically investigated in the absence and presence of hexafluoroisopropanol and p-toluenesulfonic acid (PTSA) using time-resolved absorption spectroscopy in the ultrafast time domain. Results reveal the generation of a relatively long-lived charge-separated state in this multi-electron transfer reaction, and we could confirm the generation of AQ2- and RuIII as the transient intermediates. We could rationalize the mechanistic pathway and the dynamics associated with photoinduced processes and the role of H-bonding in stabilizing charge-separated states. Transient absorption spectroscopic studies reveal that the rates of intramol. electron transfer and the mechanistic pathways associated with the PCET process are significantly different in different solvent compositions having different polarities. In acetonitrile, a concerted PCET mechanism prevails, whereas the stepwise PCET reaction process is observed in the presence of PTSA. The results of the present study represent a unique model for the mechanistic diversity of PCET reactions.4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Computed Properties of C12H12N2) was used in this study.

The first mixed ligand Mn(II) and Cd(II) complexes containing 4-methoxy-pyridine-2-carboxylic acid (4-mpic) and 4,4′-dimethyl-2,2′-bipyridine (dmbpy) were synthesized. The geometric structures of [Mn(4-mpic)2(dmbpy)] (complex 1) and [Cd(4-mpic)2(dmbpy)] (complex 2) were determined by single crystal x-ray diffraction method. FTIR and UV-visible spectra were also recorded to study vibrational and electronic properties of complexes 1 and 2. D. functional theory (DFT) calculations were also carried out to provide a deep understanding in geometric, spectroscopic, electronic and nonlinear optical (NLO) properties of complexes 1 and 2. The first-order hyperpolarizability (β) parameter calculated as 332.9736 × 10-30 esu demonstrated that complex 1 is an extremely promising candidate to NLO materials. Natural bond orbital (NBO) anal. not only verified the distorted octahedral geometries of central metal ions, but also found out the high-energy interactions responsible for biol. activities for complexes 1 and 2. Anti-cancer activities of complexes 1 and 2 were tested on human breast carcinoma cell line MCF-7 (ER and PR pos., HER2 neg.) and the triple neg. breast carcinoma cell line MDA-MB 231 (ER, PR and HER2 neg.). Dose-response relation derived from MTT assays indicates that complexes 1 and 2 are showing concentration-dependent effects, which could suggest a potential use for these drug combinations in cancer cell lines.

In 2019,Chemistry – A European Journal included an article by Nihei, Masayuki; Yanai, Yuta; Natke, Dominik; Takayama, Ryo; Kato, Marina; Sekine, Yoshihiro; Renz, Franz; Oshio, Hiroki. Synthetic Route of C12H12N2. The article was titled 《Solid-State Hydrogen-Bond Alterations in a [Co2Fe2] Complex with Bifunctional Hydrogen-Bonding Donors》. The information in the text is summarized as follows:

A hydrogen-bonding donor-acceptor system, [Co2Fe2(bpy*)4(CN)6(tp*)2](PF6)2·2ABA·4BN·2PE (1Solv), was prepared by co-crystallization of an external stimuli-responsive cyanide-bridged tetranuclear [Co2Fe2] complex and bifunctional hydrogen-bonding donors, p-aminobenzoic acid. Compound 1Solv exhibited a gradual electron-transfer-coupled spin transition (ETCST), and the removal of solvent mols. led to an abrupt thermal ETCST behavior with increased transition temperature X-ray structural anal. revealed that the modification of ETCST was caused by a significant alteration of a hydrogen-bonding mode between the tetranuclear [Co2Fe2]2+ cations and ABA mols. Variable temperature IR measurements indicated that the desolvated form, 1desolv, showed dynamic alteration of hydrogen-bonding interactions coupled with thermal ETCST behavior. These results suggested that the tetranuclear [Co2Fe2] complex shows solid-state modulations of hydrogen-bond strengths by external stimuli. In the part of experimental materials, we found many familiar compounds, such as 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Synthetic Route of C12H12N2)

E.; Salmain, Michele; Bertrand, Benoit published their research in Chemistry – A European Journal in 2021. The article was titled 《[(C C)Au(N N)]+ Complexes as a New Family of Anticancer Candidates: Synthesis, Characterization and Exploration of the Antiproliferative Properties》.Reference of 4,4′-Dimethyl-2,2′-bipyridine The article contains the following contents:

A library of eleven cationic gold(III) complexes of the general formula [(C C)Au(N N)]+ when C C is either biphenyl or 4,4-ditertbutyldiphenyl and N N is a bipyridine, phenanthroline or dipyridylamine derivative have been synthesized and characterized. Contrasting effects on the viability of the triple neg. breast cancer cells MDA-MB-231 was observed from a preliminary screening. The antiproliferative activity of the seven most active complexes were further assayed on a larger panel of human cancer cells as well as on non-cancerous cells for comparison. Two complexes stood out for being either highly active or highly selective. Eventually, reactivity studies with biol. meaningful amino acids, glutathione, higher order DNA structures and thioredoxin reductase (TrxR) revealed a markedly different behavior from that of the well-known coordinatively isomeric [(C N C)Au(NHC)]+ structure. This makes the [(C C)Au(N N)]+ complexes a new class of organogold compounds with an original mode of action.

Computed Properties of C12H12N2In 2020 ,《A paramagnetic oxalato-bridged binuclear copper(II) complex as an effective catalase inhibitor. Spectroscopic and molecular docking studies》 appeared in Journal of Molecular Structure. The author of the article were Shahraki, Somaye; Razmara, Zohreh; Shiri, Fereshteh. The article conveys some information:

A binuclear oxalato-bridged Cu complex formulated as [μ-(ox){Cu(Mebpy) (NO3) (H2O)} 2] (Mebpy is 5,5′-dimethyl-2,2′-dipyridyl and ox is oxalate) was synthesized through an environment-friendly reaction under ultrasound irradiation This complex was selected to study its mol. interactions with bovine liver catalase (BLC) using exptl. and mol. modeling methods. The enzymic activity of BLC decreased to 34.6% when the concentration of the above complex is 9.0 × 10-5 M. The fluorescence results showed that Cu complex could bind with BLC with a relatively strong affinity (Kb = 2.61 and 2.67 × 107 M-1 at 300 and 310 K, resp.). Due to Cu complex interactions, the intrinsic fluorescence of the BLC was quenched by a static quenching mechanism and hydrogen bonds and van der Waals forces were the main active forces in the interaction process. The results of mol. modeling were in good agreement with the exptl. data and showed that there is one binding site for Cu complex on BLC. Also, the in vitro antioxidant activity of the Cu complex was evaluated against 1,1-diphenyl-2-picrylhydrazyl radicals (DPPH.). Cu complex presented moderate antioxidant activity (IC50 = 25 mg L-1) in comparison with ascorbic acid. In addition to this study using 4,4′-Dimethyl-2,2′-bipyridine, there are many other studies that have used 4,4′-Dimethyl-2,2′-bipyridine(cas: 1134-35-6Computed Properties of C12H12N2) was used in this study.

《Coordination polymers driven by 2,5-dibromoterephthalic acid and chelating co-ligands: Syntheses, structures and luminescent properties》 was written by Zhang, Xinghao; Zhang, Yaowen; Jiao, Shaoshao; Song, Xiuyan; Li, Shaoxiang; Liu, Kang; Wang, Lei. Recommanded Product: 4,4′-Dimethyl-2,2′-bipyridineThis research focused onzinc cobalt dibromoterephthalato bipyridine complex photoelectron crystal structure fluorescence. The article conveys some information:

Four coordination polymers, namely, [Zn(DBT)(4,4′-dmbpy)(H2O)]n (1), [Co(DBT)(2,2′-bpy)(H2O)]n (2), [Zn(DBT)(2,2′-bpy)]n (3), [Zn(DBT)0.5(2,2′-bpy)2·(HDBT-)]n (4) (H2DBT = 2,5-dibromoterephthalic acid, 4,4′-dmbpy = 4,4′-dimethyl-2,2′-bipyridyl and 2,2′-bpy = 2,2′-bipyridyl) were synthesized under solvothermal conditions and characterized by single crystal x-ray diffraction, powder x-ray diffraction, elemental anal., IR and thermogravimetric (TG) anal. These four compounds remained stable until 150°, and the major quality loss (83-90%) occurred between 150 and 700°. In mixed ligands system, the main ligand H2DBT exhibits monodentate or bidentate bridging coordination modes and the auxiliary ligands 4,4′-dmbpy and 2,2′-bpy both possess bidentate chelate coordination modes. An objective of this study was to investigate the pivotal role of chelating ligands in the formation of low dimensional structures. As the bipyridyl ligands occupy the coordination site, compounds 1-3 all display two dimensional structures and 4 shows 1-dimensional chains, of which compounds 1 and 2 are isomorphic. The hydrogen bonds and π-π stacking work together in the formation of 3-dimensional supramol. structure of these four compounds Besides, the authors investigated their photoluminescence properties in the solid state at room temperature 1, 3 And 4 exhibited good fluorescence performance, and their strong emission peaks were located at 447 nm (λex = 285 nm) for 1, 427 nm (λex = 330 nm) for 3, and 412 nm (λex = 310 nm) for 4.
