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.

Introduction: Acute myeloid leukemia (AML) represents a disease with a very poor outcome and remains an area of significant unmet need necessitating novel therapeutic strategies. Among novel therapeutic agents, vosaroxin is a first-in-class anticancer quinolone derivative that targets topoisomerase II and induces site-selective double-strand breaks in DNA, leading to tumor cell apoptosis. Areas covered: Herein, the authors provide a comprehensive review of the preclinical development of vosaroxin. This includes coverage of vosaroxin’s mechanism of action in addition to its pharmacology and of the main studies reported over the past few years with vosaroxin when used to treat adult AML. Expert opinion: Given that vosaroxin is associated with fewer potential side effects, it may be of benefit to elderly patients with relapsed/refractory AML and to those with additional comorbidities who have previously received an anthracycline and cytarabine combination. Furthermore, vosaroxin also was seen to be active in multidrug-resistant preclinical models. However, further studies have to be performed to better evaluate its place in the armamentarium against AML.

A novel, efficient synthesis of a series of functionalized, benzo-annelated decahydrofuro[3,2-h][1,6]naphthyridine derivatives 3 has been achieved. The protocol is based on the intramolecular hetero-Diels-Alder (IMHDA) reaction of in situ formed imines derived from an N-prenylated sugar aldehyde 1 and different aromatic amines 2 in the presence of bismuth(III) chloride as catalyst. The reactions could be run under very mild conditions at room temperature, and were complete within 30 min, affording exclusively and stereoselectively the corresponding trans-fused products 3 in good-to-excellent yields (Table).

Treatment of [Rh(COD)(mu-Cl)](2) with excess (BuOK)-Bu-t and subsequent addition of 2 equiv of PIN center dot HBr in THF afforded [Rh(COD)(kappa C-2-PIN)Br] (1) (PIN = 1-isopropyl-3-(5,7-dimethyl-1,8-naphthyrid-2-yl)imidazol-2-ylidene, COD = 1,5-cyclooctadiene). The X-ray structure of 1 confirms ligand coordination to Rh(COD)Br through the carbene carbon featuring an unbound naphthyridine. Compound 1 is shown to be an excellent catalyst for the hydration of a wide variety of organonitriles at ambient temperature, providing the corresponding organoamides. In general, smaller substrates gave higher yields compared with sterically bulky nitriles. A turnover frequency of 20 000 h(-1) was achieved for the acrylonitrile. A similar Rh(I) catalyst without the naphthyridine appendage turned out to be inactive. DFT studies are undertaken to gain insight on the hydration mechanism. A 1:1 catalyst-water adduct was identified, which indicates that the naphthyridine group steers the catalytically relevant water molecule to the active metal site via double hydrogen-bonding interactions, providing significant entropic advantage to the hydration process. The calculated transition state (TS) reveals multicomponent cooperativity involving proton movement from the water to the naphthyridine nitrogen and a complementary interaction between the hydroxide and the nitrile carbon. Bifunctional water activation and cooperative proton migration are recognized as the key steps in the catalytic cycle.

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.

Synthesis and investigation of antimicrobial activity of 6 novel 1,8-naphthyridine-3-carboxylic acid derivatives are presented. Among the derivatives, compounds 4a-5b2 showed a broad-spectrum antimicrobial activity against all reference Gram-positive, Gram-negative bacteria and fungi. These compounds exhibited remarkable bactericidal activity against Staphylococcus and Bacillus sps. The tested substances 4a-5b2 were found also found to be active against Escherichia coli, Salmonella and Shigella sps. The chlorine substituted compounds 4a and 5a2 were found to be the most active towards the tested microorganisms. Compounds 4a-5b2 were found to be fungicidal against Candida sp. with a MIC values in the range of 400-2000 mu g/ml. Docking studies of these compounds with Salmonella typhi OmpF complexed with ciprofloxacin using PDB-4KRA revealed that the compounds acted as covalent crosslinker on the DNA gyrase B of the former and intercalate the latter both with higher C score values. Thus, the antibacterial activity against tested strains suggested 1,8-naphthyridine-3-carboxylic acid derivatives warrant further evaluation as potential novel antiinfective agents. The antifungal activity of these compounds was comparable to that of griseofulvin. The drug-likeness data of synthesized compounds made them promising leads for the future development as antifungal agents.

We describe herein the comprehensive theoretical and experimental studies on the transistor mobility of organic semiconductors by correlating a two-dimensional (2D) intermolecular interaction with thin-film morphology and the electronic coupling structure. We developed a novel bis-lactam-based small molecule, 1,5-dioctyl-3,7-di(thiophen-2-yl)-1,5-naphthyridine-2,6-dione (C8-NTDT), with a 2D-type C-H center dot center dot center dot O=C intermolecular interaction along the in-plane directions of the crystal packing structure, which is characteristically different from the one-dimensional-type intermolecular interaction shown in the typical bis-lactam molecule of 2,5-dioctyl-3,6-di(thiophen-2-yl)pyrrolo[3,4-c]pyrrole-1,4-dione (C8-DPPT). Experimentally and theoretically, C8-NTDT exhibited more favorable thin-film morphology and an electronic coupling structure for charge transport because of its unique 2D intermolecular interactions compared with C8-DPPT. In fact, C8-NTDT exhibited a hole mobility of up to 1.29 cm(2) V-1 s(-1) and an on/off ratio of 10(7) in a vacuum-processed device. Moreover, the high solubility with the 2D electronic coupling structure of C8-NTDT enables versatile solution processing for device fabrication without performance degradation compared to the vacuum-processed device. As an example, we could demonstrate a hole mobility of up to 1.10 cm(2) V-1 s(-1) for the spin-coated devices, which is one of the best performances among the solution-processed organic field-effect transistors based on bis-lactam-containing small molecules.

The performance of water oxidation catalysis by a Cu-based polypyridyl complex, [Cu-II(TPA)(OH2)](2+) (1H; TPA = tris-(pyridylmethyl)amine), has been investigated in neutral aqueous solution by electrochemical methods. Compared with our previously reported binuclear catalyst, [(BPMAN)(Cu-II)(2)(-OH)](3+) (2; BPMAN = 2,7-[bis(2-pyridylmethyl)aminomethyl]-1,8-naphthyridine), mononuclear catalyst 1 has a higher overpotential and lower catalytic activity toward water oxidation under the same conditions. Experimental results revealed that the O-O bond formation occurred via a water nucleophilic attack mechanism in which formal Cu-IV(O) is proposed as a key intermediate for the mononuclear catalyst 1H. In contrast, for the binuclear catalyst, O-O bond formation was facilitated by bimetallic cooperation between the two Cu-III centers.

Therefore, this conceptually novel strategy might open impressive avenues to establish green and sustainable chemistry platforms. If you like, you can also browse other articles about this kind. Thanks for taking the time to read the blog about 496-72-0, Quality Control of 3,4-Diaminotoluene.

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.

In conclusion, we affirm that quantitative kinetic descriptions of catalytic behavior continue to serve as an indispensable tool to navigate research efforts intended to model and predict the effects of solvation within porous materials, I hope to 496-72-0 help many people in the next few years.
