Dichloro[2-(A,A-dimethylaminomethyl)phenyl-C1,A]gold(iii), [Au(damp-C,A)Cl2] (1), reacts with salicylaldchyde thiosemicarbazone (H2saltsc), vanilline thiosemicarbaezone (Hvantsc), N-methylpyrrole aldehyde thiosemicarbazone (Hmepyrtsc), pyridoxal methylthiosemicarbazone (H2pydoxmetsc), 2-diphenylphosphinobenzaldehyde thiosemicarbazone (HPtsc) or variously substituted acetylpyridine thiosemicarbazones (HapRtsc; R = H, Me, Ph) with cleavage of the Au-N bond and protonation of the dimethylamino group. Compounds of general formulae [Au(Hdamp-C1)CI(L)f (L = Hsaltsc-, vantsc-, mepyrtsc1), [Au(Hdamp-C1)Cl(L)]2+ (L = H2pydoxmetsc) or [Au(Hdamp-C1)(L)]2+ (L = Ptsc-, apRtsc-, R = H, Me, Ph) have been isolated and characterized. The presence of the (T-bonded 2-(dimethylaminomethyl)phenyl ligand is mandatory to prevent reduction of the gold(in) centre. The crystal structures of [Au(Hdanip-C1)CI(HsaItsc)](PF6) (3a), [Au(Hdamp-C’)Cl(mepyrtsc)]Cl (3c), [Au(Hdamp-C1)-CI(H2pydo.xtnetsc)]Cl2-MeOH (4), [Au(Hdamp-C1)(apPhtsc)]Cl2-2 MeOH (5c) and [Au(Hdamp-C’)(Ptsc)]Cl2-1.5MeOH (6) have been elucidated, showing the gold atoms in distorted square-planar co-ordination environments. The potentially O,N,S-tridentate ligands H2saltsc and H2pydoxmetsc co-ordinate in a bidentate fashion and do not incorporate the OH groups in the chelating framework, whereas HapRtsc or HPtsc co-ordinate in a tridentate manner. Generally, one or more hydrogen atoms of the heterocyclic ligands and/or the NMe2H+ group form hydrogen bridges in the solid state structures. The preliminary results of antiproliferation tests on tumor cells demonstrate the considerable cytotoxicity of these new gold complexes. The Royal Society of Chemistry 2000.

Phosphonium salt (p-OCH3-Ph)2P(CH2OH)2Cl (MPOHC), derived phosphine ligands without and with SarGly (Sarcosine-Glycine) peptide carrier P(p-OCH3-Ph)2CH2OH (MPOH) and P(p-OCH3-Ph)2CH2SarGly (MPSG), respectively, and two copper(I) complexes [Cu(I)(dmp)(MPOH)] (1-MPOH; dmp = (2,9-dimethyl-1,10-phenanthroline)) and [Cu(I)(dmp)(MPSG)] (1-MPSG) were synthesized. The resulting compounds were characterized by elemental analysis, 1D and 2D NMR and UV?Vis absorption spectroscopies, mass spectrometry, cyclic voltammetry and by X-ray diffraction analysis. Cytotoxicity of all compounds was evaluated in vitro against colon, lung, breast, pancreatic, prostate tumor cell lines, as well as towards non-tumor cell lines: lung, kidney and keratinocyte. Stable in biological medium in the presence of atmospheric oxygen, Cu(I) complexes exerted a cytotoxic effect higher than that elicited by cisplatin against tested cancer cell lines. The introduction of methoxy group onto the phenyl rings of the phosphine ligand coordinated to the copper(I) ion resulted in a relevant increase of cytotoxicity in the case of breast, pancreatic and prostate tumor cell lines in vitro. Attachment of a peptide carrier significantly increased the selectivity towards cancer cells. Fluorescence spectroscopic data (calf thymus DNA: CT-DNA) titration), together with analysis of DNA fragmentation (gel electrophoresis) and molecular docking provided evidence for the multimodal interaction of copper compounds with DNA and showed their unusual low genotoxicity. Additionally, copper complexes were able to generate reactive oxygen species as a result of redox processes, proved by fluorescence spectroscopy and cyclic voltamperometry.

Condensation of ortho-diphenylphosphinobenzaldehyde with 2,4,6-tri-t-butyl-phenylphosphine yields the lambda2,lambda3-diphosphorus chelating agent 2a with an E-configurated phosphaalkene unit as indicated by the analysis of the NMR data. On irradiation with UV light 2a is transformed to the Z-isomer (2b). E-2a forms stable Mo(0), Pd(II) and Pt(II) chelate complexes (3-5). The X-ray structure of the molybdenum complex 3·C7H16 (space group P212121) has been determined showing the phosphaalkene moiety to be coordinated in a eta1-mode to molybdenum within a distorted six-membered chelate ring.

The reaction rate of a catalyzed reaction is faster than the reaction rate of the uncatalyzed reaction at the same temperature.50777-76-9, Name is 2-(Diphenylphosphino)benzaldehyde, molecular formula is C19H15OP. In a Article，once mentioned of 50777-76-9, name: 2-(Diphenylphosphino)benzaldehyde

An efficient and green procedure for the synthesis of Markovnikov i.e. branched vinyl sulfides in aqueous media was developed by employing the dinuclear Rh(i) complexes of hydrophilic phosphines as catalysts in the alkyne hydrothiolation with aliphatic thiols. Deuterium-labeling studies provide evidence for the aptness of these dinuclear catalysts to form selectively the Markovnikov syn-addition products. Catalyst order experiments disclose that the order with respect to the concentration of the catalyst is one, i.e. in solution the active catalyst is dinuclear with one active metal center and the second metal center contribute the cooperative effects to influence the Markovnikov selectivity in hydrothiolation. Further, the possibility of catalyst recovery and recycling experiments were also demonstrated.

With their mechanistic novelty and various modalities of reactivity, transition metal unsaturated carbene (alkenylidene) complexes have emerged as versatile intermediates for new reaction discovery. In particular, the past decade has witnessed remarkable advances in the chemistry of metal vinylidenes and allenylidenes, leading to the evolution of a diverse array of new catalytic transformations that are mechanistically distinct from those developed in the previous two decades. This review aims to provide a survey of the recent achievements in the development of organic reactions that make use of transition metal alkenylidenes as catalytic intermediates and their applications to organic synthesis.

Though much progress has been made in the inhibition of HIV-1 integrase catalysis, clinical resistance mutations have limited the promise of long-term drug prescription. Consequently, allosteric inhibition of integrase activity has emerged as a promising approach to antiretroviral discovery and development. Specifically, inhibitors of the interaction between HIV-1 integrase and cellular cofactor LEDGF/p75 have been validated to diminish proviral integration in cells and deliver a potent reduction in viral replicative capacity. Here, we have contributed to the development of novel allosteric integrase inhibitors with a high-throughput AlphaScreen-based random screening approach, with which we have identified novel 5-carbonyl-1H-imidazole-4-carboxamides capable of inhibiting the HIV-1 integrase-LEDGF/p75 interaction in vitro. Following a structure-activity relationship analysis of the initial 1H-imidazole-4,5- dicarbonyl core, we optimized the compound’s structure through an industrial database search, and we went further to synthesize a selective and non-cytotoxic panel of inhibitors with enhanced potency.
