37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2, belongs to ruthenium-catalysts compound, is a common compound. In a patnet, once mentioned the new application about 37366-09-9, Recommanded Product: 37366-09-9

The DNA binding of cationic complexes of the type [(eta6-arene)Ru(Aa)(dppz)] (CF3SO3)n (arene = C6H6, Me3C6H3, C6Me6; dppz = dipyrido[3,2-a:2?,3?-c]phenazine; n = 1, Aa = AcH-1cysOH 4-6; n = 2, Aa = AcmetOH 7-9; n = 3, Aa = H2metOMe 10-12) containing S-coordinated amino acids (HcysOH = L-cysteine, HmetOH = L-methionine) has been studied by UV-vis titration and 2D-NOESY. Stable intercalative binding is indicated for these complexes by their steady decrease in absorbance at maxima between 350 and 390 nm on titration with CT DNA and the bathochromic shifts of these absorption maxima. Taking 4-12 and the analogous (eta6-C6Me6)RuII complexes of the tripeptides HglyglycysOH (n = 1, 13) and HglyglymetOH (n = 2, 15; HglyOH = glycine) into account, typical DNA binding constant (Kb) ranges can be established for (eta6-arene)RuII complexes: 5.3 × 104-1.6 × 105 M-1 for monocations, 6.3 × 105 9.9 × 105 M-1 for dications and 1.6 × 106-5.5 × 106 M-1 for trications. These Kb values clearly reflect a strengthening of electrostatic interactions with the negatively charged phosphodiester backbone of DNA as the total cation charge increases. A consistent trend to higher Kb values is also apparent for the coligand series C6H6 < Me3C6H3 < C6Me6 with the relative increase being, in general, more pronounced for C6H6/Me3C6H3 pairs. The strong electronic influence of the coligand on dppz intercalation is also reflected by marked increases DeltaTm of 18.2-18.5 C in the CT DNA thermal denaturation temperature for di- and tri-cationic (eta6-C6Me6)RuII complexes. Upfield 1H NMR chemical shifts and characteristic NOE cross peaks for the dppz protons of the 1 : 1 complex formed between 9 and d(GTCGAC)2 are consistent with a side-on intercalation adjacent to T2 from the major groove. Balanced chemical reaction does not necessarily reveal either the individual elementary reactions by which a reaction occurs or its rate law.Recommanded Product: 37366-09-9.

Application of 37366-09-9, Chemistry can be defined as the study of matter and the changes it undergoes. You’ll sometimes hear it called the central science because it is the connection between physics and all the other sciences, starting with biology.37366-09-9, Name is Dichloro(benzene)ruthenium(II) dimer, molecular formula is C12H12Cl4Ru2. In a patent, introducing its new discovery.

Ionic liquids comprised of cationic arene-ruthenium chelate complexes and the bis(trifluoromethanesulfonyl)amide anion (=Tf2N), [(arene)RuCl(L)](Tf2N), where L = MeS(CH2)nSR (R = Me, Bu; n = 1-3), Me2N(CH2)2NMe 2 and arene = p-cymene, C6H6, have been prepared, and their thermal properties, structures, and reactivities have been investigated. These liquids undergo direct ligand exchange reactions in line with their thermal stabilities. Thermogravimetric analysis revealed that the thermal stabilities of the complexes are higher as the bridging group of the chelate ligand becomes longer. The complexes with MeSCH2SMe transform thermally into dinuclear complexes. The coordination structures were determined crystallographically.

It is now well established that ruthenium complexes are attractive alternatives to platinum-based anticancer agents. Most of the ruthenium compounds currently under investigation contain a single metal center. The synthesis of multinuclear analogues may provide access to novel complexes with enhanced biological activity. In this work, we have synthesized a set of three trinuclear complexes containing organometallic ruthenium fragments?(arene)RuCl?coordinated to a 2,4,6-tris(di2-pyridylamino)-1,3,5-triazine core [(Arene=benzene (2), p-cymene (1), or hexamethylbenzene (3)]. The interaction of the complexes with DNA was extensively studied using a variety of biophysical probes as well as by molecular docking. The complexes bind strongly to DNA with apparent binding constants ranging from 2.20 to 4.79 ×104 M?1. The binding constants from electronic absorption titrations were an order of magnitude greater. The mode of binding to the nucleic acid was not definitively determined, but the evidence pointed to some kind of non-specific electrostatic interaction. None of the complexes displayed any significant antimicrobial activity against the organisms that were studied and exhibited anticancer activity only at high (>100 muM) concentration.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 37366-09-9 is helpful to your research., Application of 37366-09-9

FR901464 is a potent anticancer natural product that lowers the mRNA levels of oncogenes and tumor suppressor genes. In this article, we report a convergent enantioselective synthesis of FR901464, which was accomplished in 13 linear steps. Central to the synthetic approach was the diene-ene cross olefin metathesis reaction to generate the C6-C7 olefin without the use of protecting groups as the final step. Additional key reactions include a Zr/Ag-promoted alkynylation to set the C4 Stereocenter, a mild and chemoselective Red-Al reduction, a reagent-controlled stereoselective Mislow-Evans-type [2,3]-sigmatropic rearrangement to install the C5 Stereocenter, a Carreira asymmetric alkynylation to generate the C4? stereocenter, and a highly efficient ring-closing metathesis-allylic oxidation sequence to form an unsaturated lactone. The decomposition pathways of FR901464’s right fragment were studied under physiologically relevant conditions. Facile epoxide opening by beta-elimination gave two enones, one of which could undergo dehydration via its hemiketal to form a furan. To prevent this decomposition pathway, a right fragment was rationally designed and synthesized. This analogue was 12 times more stable than the right fragment of the natural product. Using this more stable right fragment analogue, an FR901464 analogue, meayamycin, was prepared in 13 linear steps. The inhibitions of human breast cancer MCF-7 cell proliferation by synthetic FR901464 and meayamycin were studied, and the GI50 values for these compounds were determined to be 1.1 nM and 10 pM, respectively. Thus, meayamycin is among the most potent anticancer small molecules that do not bind to either DNA or microtubule.

Natural retinoids and curcuminoids are known for their broad spectrum of biological properties, such as antioxidant, anti-inflammatory, antitumor, and so forth. In this work, a convenient synthesis of aromatic retinoids and curcuminoids from vinyl or allyl ketones, and the corresponding alcohols, using olefin metathesis as a key reaction, was elaborated. The best yields and diastereoselectivities were obtained from allylic or homoallylic alcohols by employing the two-step cross-metathesis/oxidation procedure. The synthesized analogues were tested for their antiproliferative activity on human cancer cell lines of various origin (leukemia CEM, adenocarcinoma MCF7, cervical carcinoma HeLa) as well as for their antioxidant and anti-inflammatory activity in vitro. All examined derivatives exhibited strong anti-inflammatory activity in vitro without affecting cell viability. They also showed strong cytotoxicity against leukemia cell line CEM, except for 18 and 35. The antioxidant activity of the tested compounds was rather weak.

The multijet oscillating disk (MJOD) flow reactor is a relatively new technology for continuous flow synthesis. This technology is still under investigation as an all-round platform for flow synthesis. In this article, findings are disclosed from a project where a MJOD flow reactor rig (reactor volume of ?50 mL) was investigated as the reaction platform for ring closing metathesis and cross (self) metathesis reaction, using reaction mixture volumes down to only ?5 mL. The Hoveyda-Grubbs second-generation catalyst was used without an inert atmosphere. The results of the flow synthesis provided excellent selectivity and high yield. For comparison purposes, the syntheses conducted in the MJOD reactor were compared with similar literature experiments performed with other flow technologies and batch conditions.

Two ruthenium(III) complexes bearing the thiazole ligand, namely, thiazolium (bisthiazole) tetrachlororuthenate (I, TzlCR) and thiazolium (thiazole, DMSO) tetrachlororuthenate (II, TzNAMI) were prepared and characterized. The crystal structures of both complexes were solved by X-ray diffraction methods and found to match closely those of the corresponding imidazole complexes. The behavior in aqueous solution of both TzlCR and TzNAMI was analyzed spectroscopically. The time-dependent spectrophotometric profiles resemble closely those of the related ICR and NAMI-A anticancer compounds, respectively. It is observed that replacement of imidazole with thiazole, a less basic ligand, produces a significant decrease of the ligand exchange rates in the case of the NAMI-like compound. The main electrochemical features of these ruthenium(III) thiazole complexes were determined and compared to those of ICR and NAMI-A. Moreover, some preliminary data were obtained on their biological properties. Notably, both complexes exhibit higher reactivity toward serum albumin than toward calf thymus DNA; cytotoxicity is negligible in line with expectations. A more extensive characterization of the pharmacological properties in vivo is presently in progress.
