Ruthenium catalysts

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.15746-57-3, Name is Cis-Dichlorobis(2,2′-bipyridine)ruthenium(II), molecular formula is C20H16Cl2N4Ru.

Ru(II)-complex-based DNA photocleavers have been extensively studied for their potential application in photodynamic therapy (PDT) and photodynamic antimicrobial chemotherapy (PACT). However, their MLCT absorption maxima are generally shorter than 600 nm, limiting PDT/PACT application severely. In this work, by incorporating a 5-chloro-8-oxyquinolate-based noninnocent ligand into a merocyanine scaffold Cl-7-IVQ, we obtained a new Ru complex of this ligand, [Ru(bpy)2(Cl-7-IVQ)]2+, which has intense absorption in the window 600-700 nm and enables an efficient ?OH-mediated DNA photocleavage. This long-wavelength absorption band has a character of MLLCT transition from the hybrid Ru(dpi)-Cl-7-IVQ(pi) orbital to the pi*(Cl-7-IVQ) orbital and thus a contribution from the pipi* transition of the merocyanine framework, which endows the complex with a molar extinction coefficient as high as 1.73 × 104 M-1 cm-1 at 649 nm and allows for an efficient DNA photocleavage under an irradiation of low intensity. [Ru(bpy)2(Cl-7-IVQ)]2+ represents the first Ru(II)-complex-based DNA photocleaver that has an MLCT absorption maximum above 600 nm and can selectively inactivate E. coli bacterial cells over HeLa cells upon red light irradiation.

Pyrazin-2-yl 2-pyridyl sulfide (pzpys) has been prepared by reaction of 2-sulfanylpyridine with chloropyrazine. As shown by 1H NMR spectroscopy, its major isomer has two binding sites which are inequivalent, one chelating through the N1-pyrazine and N-pyridine atoms, the other monodentate through the N4 atom of the pyrazine ring. By reaction of pzpys with [RuL2(NO)(NO2)][PF6]2 [(L = 2,2?-bipyridine (bipy) or di-2-pyridyl sulfide (dps)] the mononuclear complexes [RuL2(pzpys)(NO2)][PF6] have been obtained in which pzpys is the monodentate. The reactions of pzpys with cis-[RuL2Cl2] complexes [L = bipy, 1,10-phenanthroline (phen) or dps] have been studied. The dps derivative reacts with a large excess of pzpys affording [Ru(dps)2(pzpys)Cl]-[PF6] in which pzpys is monodentate. On the contrary the bipy and phen (L) derivatives, under the same experimental conditions, undergo substitution of both chloride ligands giving, as major products, [RuL2(pzpys)][PF6]2 in which pzpys is chelated. When the reactions were carried out in the presence of a stoichiometric amount of pzpys the binuclear complexes [L2Ru(pzpys)RuL2Cl][PF6]3 (L = bipy or phen) were slowly formed. The mononuclear complexes have been used as ligands in the reactions with [Ru-(bipy)2Cl2] giving the new binuclear species [L2Ru(pzpys)RuL2(NO2)][PF6] 3 (L = bipy or phen). The compounds have been fully characterized by infrared, UV/VIS, 1H and 13C NMR spectroscopies. In acetonitrile solution [Ru(bipy)2(pzpys)Cl][PF6] undergoes a reversible RuII ? RuIII electron transfer. In contrast, the one-electron oxidation of [Ru(dps)2(pzpys)Cl][PF6], [Ru(bipy)2(pzpys)(NO2)][PF6] and [Ru(bipy)2(pzpys)][PF6]2 is complicated by subsequent chemical reactions. The binuclear complex [(bipy)2Ru(pzpys)Ru(bipy)2Cl][PF6]3 undergoes two consecutive one-electron oxidations (DeltaE?? = 0.55 V), which allow the corresponding RuIIRuIII species to be classified as a completely delocalized (Class III) mixed-valence compound.

To access high-quality small-molecule libraries to screen lead candidates for neglected diseases exemplified by human African trypanosomiasis, we sought to develop a synthetic process that would produce collections of cyclic scaffolds relevant to an assortment of natural products exhibiting desirable biological activities. By extracting the common structural features among several sesquiterpenes, including artemisinin, anthecularin, and transtaganolides, we designed six types of scaffolds with systematic structural variations consisting of three types of stereochemical relationships on the sp3 ring-junctions and two distinct arrays of tricyclic frameworks. A modular and stereodivergent assembly of dienynes exploiting a versatile manifold produced a series of cyclization precursors. Divergent cyclizations of the dienynes employing tandem ring-closing metathesis reactions overrode variant reactivities of the cyclization precursors, leading to the six canonical sets of the tricyclic scaffolds incorporating a diene group. Screenings of trypanosomal activities of the canonical sets, as well as regio- and stereoisomers of the tricyclic dienes, allowed generation of several antitrypanosomal agents defining the three-dimensional shape of the pharmacophore. The candidate tricyclic dienes were selected by primary screenings and further subjected to installation of a peroxide bridge, which generated artemisinin analogues that exhibited potent in vitro anti-trypanosomal activities comparable or even superior to those of artemisinin and the approved drugs, suramin and eflornithine.

The reactions of 2-(pyridine-2-ylmethylsulfanyl)benzoic acid (L) with [(5-Cp/6-benzene)MCl(-Cl)]2, (benzene, M = Ru; Cp, M = Rh, Ir) at room temperature followed by treatment with NH 4PF6 result in a new class of water-soluble half-sandwich complexes [(5Cp/6-benzene)M(L)Cl][PF6] (13, respectively, for M = Ru, Rh, Ir). Their characteristic HR-MS and 1H and 13C{1H} NMR spectra have been found. The single-crystal structures of 13 have been established with X-ray crystallography. The Ru S, Rh S, and Ir S bond lengths are 2.4079(6), 2.3989(10), and 2.3637(14), respectively. Complexes 13 have been found to be efficient for catalytic transfer hydrogenation (TH) of carbonyl compounds in water with glycerol as a hydrogen donor. Glycerol has been explored for TH in water for the first time. The efficiency in water of other hydrogen sources, viz. HCOOH, citric acid, ascorbic acid, and 2-propanol, is less and/or is pH dependent. Catalysis with glycerol as a hydrogen source is pH independent and appears to be homogeneous. Higher reactivity for the Rh complex in comparison to the Ru and Ir species has been observed. DFT calculations are generally consistent with the experimental values of bond lengths and angles and catalytic reactivity order.

The manzamine alkaloids are absolutely one of the most fascinating marine natural products. The representative manzamine alkaloids, manzamines A?C, were isolated from a marine sponge Haliclona sp. collected off Cape Manzamo, Okinawa, Japan. The manzamine alkaloids are a unique class of alkaloids possessing a characteristic heterocyclic system, and exhibit a diverse range of bioactivities including cytotoxicity, antimicrobial activity, antimalarial activity, antiviral and antiinflammatory activities, antiinsecticidal activity, and proteasome inhibitory activity. About 100 manzamine alkaloids have been isolated from more than 16 species of marine sponges belonging to 5 families. The unusual ring systems, an intriguing suggested biogenetic pathway, and promising biological activities of manzamine alkaloids have attracted great interest as challenging targets for the total synthesis. This review is the continuation of the previous review published in volume 60 of The Alkaloids and covers isolation, structure elucidation, biosynthesis and biogenesis, chemical synthesis, and biological activity of manzamine alkaloids reported from 2003 to 2018.
