Carbene Formation and Transfer at a Dinickel Active Site

The synthesis and reactivity of a dinickel bridging carbene is described. The previously reported [i-PrND]Ni-2(C6H6) complex (NDI = naphthyridine-diimine) reacts with Ph2CN2 to generate a metastable diazoalkane adduct, which eliminates N-2 at 60 degrees C to yield a paramagnetic Ni-2(mu-CPh2) complex. The Ni-2(mu-CPh2) complex undergoes carbene transfer to t-BuNC via an initial isonitrile adduct, which upon heating releases free t-BuNCCPh2. On the basis of this sequence of stoichiometric reactions, a catalytic carbene transfer reaction is demonstrated.

Note that a catalyst decreases the activation energy for both the forward and the reverse reactions and hence accelerates both the forward and the reverse reactions. you can also check out more blogs about 179324-87-9. Safety of (R)-BoroLeu-(+)-Pinanediol trifluoroacetate.

A Novel Colorimetric and Fluorescent Off-On Chemosensor for Cu2+ Based on a Rhodamine Derivative Bearing Naphthyridine Group

A new rhodamine-based derivative bearing a naphthyridine group (compound 1) was synthesized as a colorimetric and fluorescent off-on chemosensor for Cu2+ in aqueous solutions. The sensing behaviors of 1 toward various metal ions in neutral aqueous solutions were investigated by absorption and fluorescence spectroscopies. Compound 1 is found to exhibit a significant increase in absorbance at 561 nm and an amplified fluorescence at 590 nm toward Cu2+ in a selective, sensitive and rapid manner. The quantification of Cu2+ by 1 using an absorption spectroscopy method was satisfactory in the linear working range 0.9-10 mu M, with a detection limit of 5.4 x 10(-8) M for Cu2+ and good tolerance of other metal ions. Upon addition of Cu2+, the spirolactam ring (colorless and nonfluorescent) of 1 was opened to ring-opened amide (red color and fluorescent) and a 1:1 stoichiochemetry for the 1-Cu2+ complex was formed with an association constant of 1.57 x 10(4) M-1.

Discovery of a Novel FGFR4 Selective Inhibitor via Structure-Activity Relationship Studies of FGF401

A set of analogues of FRF401 were designed and synthesized, and their FGFR4 inhibition and antitumor activity as well as the structure-activity relationship (SAR) studies were screened. It was found that N-(5-cyano-4-((2-methoxyethyl)-amino)pyridin-2-yl)-7-formyl-6-((N-methyltetrahydro-2H-pyran-4-carboxamido)methyl)-1,2,3,4-tetrahydro-1,8-naphthyridine-1-carboxamide (8ac) not only showed superior FGFR4 inhibitory activity compared with FGF401 and excellent selectivity in enzymatic and cellular level, but also dramatically inhibited tumor growth and induced tumor regression in hepatocellular carcinoma xenograft model.

Ultrafast 2,7-Naphthyridine-Based fluorescent probe for detection of thiophenol with a remarkable Stokes shift and its application In vitro and in vivo

2,7-Naphthyridine derivatives were developed as fluorophores for the first time to design two fluorescence probes, AND-DNP and ND-DNP, which can be applied for detecting thiophenol in aqueous media. Comparing with ND-DNP, AND-DNP showed more favorable properties such as lower background, larger Stokes shift, and higher fluorescence quantum yield for detecting thiophenol. Moreover, the experimental results were verified by theoretical calculations. Hence, AND-DNP was selected as the superior fluorescence probe to detect thiophenol because of its high sensitivity and selectivity. Based on the experimental results, AND-DNP showed a remarkably larger Stokes shift (225 nm), faster response speed (30 s) and higher fluorescence enhancement (240-fold) than most other fluorescent probes for thiophenol reported in the literature. For an extended application, AND-DNP was applied to detect thiophenol quantitatively in real water samples. Meanwhile, AND-DNP also detected thiophenol via red emission in living A549 cells and zebrafish. All these results proved AND-DNP’s potential value as an accurate probe for imaging thiophenol in different environments.

Highly efficient construction of pentacyclic benzo[b]indeno-[1,2,3-de][1,8]naphthyridine derivatives via four-component domino reaction

A series of new octahydrobenzo[b]indeno[1,2,3-de][1,8]naphthyridine and decahydropyrido[2,3,4-gh]phenanthridine derivatives were synthesized via a four-component domino reaction under microwave irradiation. This one-pot transformation, which involved multiple steps and did not require the use of a catalyst, constructed four new C-C bonds, two new C-N bonds, and three new rings, with efficient use of all reactants.

New polynuclear 1,5-naphthyridine-silver(I) complexes as potential antimicrobial agents: The key role of the nature of donor coordinated to the metal center

New polynuclear silver(I) complexes with 1,5-naphthyridine (1,5-naph), [Ag(NO3)(1,5-naph)](n) (Ag1), [Ag (CF3COO)(1,5-naph)]n (Ag2) and [Ag(CF3SO3)(1,5-naph)](n) (Ag3) were synthesized by the reaction of the corresponding silver(I) salt and 1,5-naph in ethanol at room temperature. These complexes were characterized by NMR, IR and UV Vis spectroscopy, while their crystal structures were determined by single-crystal X-ray diffraction analysis. In all these complexes, 1,5-naph acts as a bridging ligand between two Ag(I) ions, while the remaining coordination sites are occupied by oxygen atom(s) of the corresponding anion. The antimicrobial efficiency of these silver(I) complexes was evaluated against the broad panel of Gram-positive and Gram-negative bacteria and fungi. The complexes showed good to moderate antibacterial activity with the minimal inhibitory concentration (MIC) values being in the range 2.5-100 mu g/mL (6.5-333.3 mu M), while their antifungal activity against the investigated Candida spp. was significantly higher (MIC = 0.78-6.25 mu g/mL; 2.6-20.8 mu M). Moreover, complexes Ag1 and Ag2 effectively inhibited C. albicans biofilms formation, while Ag1 was also shown to inhibit the formation of mixed C. albicans/Pseudomonas aeruginosa biofilms. Toxicological evaluations on zebrafish (Dario rerio) embryos revealed that all silver(I) complexes could be applied as antifungal agents, whereas Ag3 had the best therapeutic potential showing both the lowest MIC values against the tested Candida strains and the non-toxic in vivo response in the zebrafish embryos at these doses.

Cyanido-Bridged Fe-II-M-I Dimetallic Hofmann-Like Spin-Crossover Coordination Polymers Based on 2,6-Naphthyridine

Two new 3D spin-crossover (SCO) Hofmann-type coordination polymers {Fe(2,6-naphthy)[Ag(CN)(2)][Ag-2(CN)(3)]} (1; 2,6-naphthy = 2,6-naphthyridine) and {Fe(2,6-naphthy)-[Au(CN)(2)](2)}center dot 0.5PhNO(2) (2) were synthesized and characterized. Both derivatives are made up of infinite stacks of {Fe[Ag(CN) (2)](2)-[Ag-2(CN)(3)]}(n) and {Fe[Au(CN)(2)](2)}(n) layered grids connected by pillars of 2,6-naphthy ligands coordinated to the axial positions of the FeII centers of alternate layers. The in situ generated [Ag-2(CN)(3)](-) linkers define wide rectangular windows that favor the interpenetration of three identical 3D networks, strong argentophilic interactions between them, and the generation of a densely packed structure without accessible void spaces. In contrast, the smaller rhombus-shaped window in 2 affords a structure made up of doubly interpenetrated 3D networks with strong aurophilic interactions between them and accessible voids partially occupied by nitrobenzene molecules. Compound 1 displays a relatively abrupt two-step SCO in the temperature interval 150-215 K, whereas 2 features an incomplete one-step SCO behavior (T-1/2 = 166 K) that extends over 150 K.
