Neutral and cationic ruthenium carbonyl complexes [Ru(CO) (2,2?-dipyridylamine)(PR3)Cl2] and [Ru(CO)(N-N)(PPh3)2(H)]Cl: Synthesis, structural characterization and transfer-hydrogenation

The neutral complexes [Ru(CO)(dpa)(PR3)Cl2] (R = Ph (1) or p-tol (2); dpa = 2,2?-dipyridylamine) were synthesized by the reaction of [Ru(CO)(dmf)(PR3)2Cl2] (dmf = N,N-dimethylformamide) and the dpa ligand, while the cationic carbonyl hydride complexes [Ru(CO) (N-N)(PPh3)2(H)]Cl were synthesized by reaction of [Ru(CO)(PPh3)3Cl(H)] and the appropriate N-N ligand [N-N = 2,2?-bipyridine = bipy (3), 2,2?-4,4?dimethyl-bipyridine = dmb (4) and 2,2?-dipyridylamine = dpa (5)]. The complexes were characterized by NMR (31P, 1H and HMBC 1H-31P), FTIR, elemental analysis and X-ray diffraction. The molecular structure of [Ru(CO)(dpa)(PPh3) Cl2] (1) was determined by X-ray crystallography. The crystal packing is stabilized by strong (CH3)O-H…Cl and N-H…OH(CH3) hydrogen bonds between symmetry-related molecules leading to the formation of dimers. Complexes 1-6 were evaluated as pre-catalysts for the reduction of acetophenone under transfer-hydrogenation conditions using isopropanol as hydrogen source, and conversions up to 86 % in 4 h were achieved.

A planar 2,2?-dipyridylammonium salt : Synthesis and structure

Reaction of 2,2?-dipyridylamine (DPA) with hexafluorophosphoric acid (HPF6) in methanol generates white rod-shaped crystals of HDPA.PF6,H2O. The salt is characterised by C, H and N analyses, FT-IR, 1H NMR, mass spectroscopy and molar conductance measurement. The X-ray crystal structure of the salt has been determined. The structure shows that the salt is monomeric. The amine nitrogen is strongly hydrogen bonded with oxygen atom of water. Two pyridyl rings are almost planar which is a rarity in the coordination chemistry of DPA. Semi-empirical AM1 calculation was also performed to delve into the novel situation.

Identification of GSK3186899/DDD853651 as a Preclinical Development Candidate for the Treatment of Visceral Leishmaniasis

The leishmaniases are diseases that affect millions of people across the world, in particular visceral leishmaniasis (VL) which is fatal unless treated. Current standard of care for VL suffers from multiple issues and there is a limited pipeline of new candidate drugs. As such, there is a clear unmet medical need to identify new treatments. This paper describes the optimization of a phenotypic hit against Leishmania donovani, the major causative organism of VL. The key challenges were to balance solubility and metabolic stability while maintaining potency. Herein, strategies to address these shortcomings and enhance efficacy are discussed, culminating in the discovery of preclinical development candidate GSK3186899/DDD853651 (1) for VL.

Synergistic effect of green tea polyphenols with trolox on free radical-induced oxidative DNA damage

The antioxidant effect of the principal polyphenolic components extracted from green tea leaves, namely (-)-epicatechin (EC), (-)-epigallocatechin (EGC), (-)-epicatechin gallate (ECG) and (-)-epigallocatechin gallate (EGCG), and their synergistic antioxidant effects with trolox against oxidative DNA damage were studied. The oxidative DNA damage was initiated by a water-soluble azo initiator, 2,2?-azobis (2-amidinopropane hydrochloride) (AAPH) and the ability of green tea polyphenols and/or trolox (a water-soluble analogue of alpha-tocopherol) to inhibit the oxidative damage of DNA was assessed, in vitro, by measuring the conversion of supercoiled pBR322 plasmid DNA to the open circular and linear forms. It was found that these green tea polyphenols could significantly inhibit the oxidative damage of DNA synergistically with trolox, with an activity sequence of EC = ECG > EGCG > EGC.

Synthesis and evaluation of various heteroaromatic benzamides as analogues of ?ylidene-benzamide cannabinoid type 2 receptor agonists

The CB2 receptor is an attractive target for the treatment of a wide range of diseases and pathological conditions. Compounds that selectively activate the CB2 receptor are desirable as this avoids CB1-mediated psychoactive effects. Heteroarylidene-benzamides have demonstrated efficacy as selective CB2 receptor agonists. We aimed to expand the structure-activity relationship studies of this series of compounds by investigating the heteroaromatic core via the synthesis and in vitro evaluation of a small library of various heteroaromatic benzamide analogues. As heteroaromatic amides are privileged scaffolds in drug design, methods to synthesise them are of interest. Concise and reliable synthetic strategies were developed to access these novel analogues. The ?ylidene-benzamide moiety is shown to be essential for CB activity as all amide derivatives exhibit no functional activity at either CB2 or CB1 receptors.

N-Heterocyclic Carbene Ligand-Enabled C(sp3)-H Arylation of Piperidine and Tetrahydropyran Derivatives

PdII-catalyzed C(sp3)-H arylation of saturated heterocycles with a wide range of aryl iodides is enabled by an N-heterocyclic carbene (NHC) ligand. A C(sp3)-H insertion step by the PdII/NHC complex in the absence of ArI is demonstrated experimentally for the first time. Experimental data suggests that the previously established NHC-mediated Pd0/PdII catalytic manifold does not operate in this reaction. This transformation provides a new approach for diversifying pharmaceutically relevant piperidine and tetrahydropyran ring systems.
