Reaction of cis-[Mo-2(OAc)(2)(CH3CN)(6)][BF4](2) with NP-Et, Me (2-ethyl-3-methyl-1,8-naphthyridine) in acetonitrile provides trans-[Mo-2(NP-Et, Me)(2)(OAc)(2)(CH3CN)][BF4](2) (1). Partial protonation of 1 by HBF4 center dot Et2O in acetonitrile leads to trans-[Mo-2(NP-Et, Me)(2)(OAc)(CH3CN)(3)][BF4](3) (2). In both compounds, NP-R ligands are arranged in a head-to-head (HH) fashion leaving one of the axial sites vacant. Substitution of acetonitriles by NP-Me (3-methyl-1,8-naphthyridine) in trans-[Mo-2(NP-tz)(2)(OAc)(CH3CN)(2)][BF4](3) provides trans-[Mo2(NP-tz) 2(OAc)(NP-Me)][BF4] 3 (3) with retention of configuration. Fully solvated dimolybdenum( II) compound reacts with NP-NH2 to provide [Mo-2(NP-NH2)(2)(NP-NH)(CH3CN)(2)][BF4](3) (4) in which the NP-NH2 ligands are trans and arranged in a HH fashion. The deprotonated ligand (NP-NH ) binds the dimetal unit utilizing naphthyridine nitrogen and amido nitrogen.

Chemical Research Letters, May 2021. Chemistry is a science major with cience and engineering. The main research directions are chemical synthesis, and research on the structure and performance of functional materials. In an article, author is Oyama, Dai, once mentioned the application of 496-72-0, Name is 3,4-Diaminotoluene. Now introduce a scientific discovery about this category, Recommanded Product: 496-72-0.

Both stereoisomers of the novel ruthenium complex [Ru(tpy)(pynp)(CO)](2+) containing 2,2′:6′,2 ”-terpyridine (tpy), a terminal carbonyl, and the unsymmetrical bidentate naphthyridine ligand 2-(2-pyridyl)-1,8-naphthyridine (pynp) were selectively synthesized. In addition, two more ruthenium complexes [Ru(ptpy)(pynp)(CO)](2+) containing 4′-phenyl-2,2′:6′,2 ”-terpyridine (ptpy) instead of tpy were also prepared. These complexes were fully characterized and their molecular structures were determined by X-ray crystallography. Some obvious differences between the isomers were revealed by the structural, computational, and spectroscopic results. Furthermore, redox properties and carbonyl ligand-based reactions of these four complexes were examined to evaluate the steric and electronic effects of the other ligands on the carbonyl reactivity. Both effects, based on the structural differences, exerted a large influence on the reactivity.

New Advances in Chemical Research in 2021. As an important bridge between the micro and macro material world, chemistry is one of the main methods and means for humans to understand and transform the material world. In an article, author is Madak, Joseph T., once mentioned the application of 496-72-0, Name is 3,4-Diaminotoluene, molecular formula is C7H10N2. Now introduce a scientific discovery about this category, Recommanded Product: 3,4-Diaminotoluene.

We pursued a structure-guided approach toward the development of improved dihydroorotate dehydrogenase (DHODH) inhibitors with the goal of forming new interactions between DHODH and the brequinar class of inhibitors. Two potential residues, T63 and Y356, suitable for novel H-bonding interactions, were identified in the brequinar-binding pocket. Analogues were designed to maintain the essential pharmacophore and form new electrostatic interactions through strategically positioned H-bond accepting groups. This effort led to the discovery of potent quinoline-based analogues 41 (DHODH IC50 = 9.71 +/- 1.4 nM) and 43 (DHODH IC50 = 26.2 +/- 1.8 nM). A cocrystal structure between 43 and DHODH depicts a novel water mediated H-bond interaction with T63. Additional optimization led to the 1,7-naphthyridine 46 (DHODH IC50 = 28.3 +/- 3.3 nM) that forms a novel H-bond with Y356. Importantly, compound 41 possesses significant oral bioavailability (F = 56%) and an elimination t(1/2) = 2.78 h (PO dosing). In conclusion, the data supports further preclinical studies of our lead compounds toward selection of a candidate for early-stage clinical development.

An efficient green protocol for the synthesis of complex hybrid heterocycles containing [1,6]-naphthyridine and coumarin/pyrazole moieties was established, involving an intramolecular [4 + 2] hetero Diels-Alder reaction as the key step. The biologically significant 12,13-dihydro-6H-benzo[h]chromeno[3,4-b][1,6]naphthyridin-6-ones and 6,10-dihydro-5H-benzo[h]pyrazolo[3,4-b][1,6]naphthyridines were synthesized starting from 2-(N-propargylamino)-arylaldehydes and 3-aminocoumarins or 3-methyl-1-aryl-1H-pyrazol-5-amines in the presence of an Amberlyst-15 catalyst in PEG-200 in good yields. The easy access to diverse complex molecules in a single operation from readily available starting materials, a commercially available, transition metal-free and recyclable catalyst, the use of a green solvent, a very high atom economy and the release of water as the only side product are the highlights of this protocol.

NIR-Absorbing Ru(II)Complexes Containing alpha-Oligothiophenes for Applications in Photodynamic Therapy

The design of near-infrared (NIR)-active photosensitizers (PSs) for light-based cancer treatments such as photodynamic therapy (PDT) has been a challenge. While several NIR-Ru(II)scaffolds have been reported, this approach has not been proven in cells. This is the first report of NIR-Ru(II)PSs that are phototoxic to cancer cells, including highly pigmented B16F10 melanoma cells. The PS family incorporated a bis(1,8-naphthyridine)-based ligand (tpbn), a bidentate thiophene-based ligand (nT;n=0-4), and a monodentate 4-picoline ligand (4-pic). All compounds absorbed light >800 nm with maxima near 730 nm. Transient absorption (TA) measurements indicated thatn=4 thiophene rings (4T) positioned the PDT-active triplet intraligand charge transfer ((ILCT)-I-3) excited state in energetic proximity to the lowest-lying triplet metal-to-ligand charge transfer ((MLCT)-M-3).4Thad low-micromolar phototoxicity with PI(vis)and PI(733nm)values as large as 90 and 12, respectively. Spectroscopic studies suggested that the longer-lived (tau(TA)=3-6 mu s)(ILCT)-I-3 state was accessible from the(3)MLCT state, but energetically uphill in the overall photophysics. The study highlights that phototoxic effects can be achieved with NIR-absorbing Ru(II)PSs as long as the reactive(3)ILCT states are energetically accessible from the low-energy(3)MLCT states. It also demonstrates that tissue-penetrating NIR light can be used to activate the PSs in highly pigmented cells where melanin attenuates shorter wavelengths of light.

1,8-Naphthyridinecarbaldehydes and Their Methyl-Substituted Precursors: Synthesis, Molecular Structures, Supramolecular Motifs and Trapped Water Clusters

1,8-Naphthyridinecarbaldehydes bearing chlorine, pyrrolidinyl, piperidinyl or morpholinyl groups, were synthesised by oxidation of their methyl-substituted precursors. The prepared carbaldehydes represent valuable starting materials for the construction of systems that are useful for supramolecular and medicinal chemistry. Single-crystal X-ray diffraction studies of four carbaldehydes and six methyl derivatives provided interesting information about the supramolecular motifs in the crystal structures of solvent-free and solvated naphthyridines. The formation of interesting water clusters, for example, T4(2) water tape, was observed in the case of 7-methyl-2-(piperidin-1-yl)-1,8-naphthyridine as well as in the crystal structure of a by-product 7-(morpholin-1-yl)-1,8-naphthyridine-2-carboxylic acid. Knowledge of the detailed structural properties of water clusters is of great research interest to a broad range of scientific disciplines.
