In a document, author is Tan, Zhenda, introduce the new discover.

Selective linkage of renewable alcohols and ammonia into functional products would not only eliminate the prepreparation steps to generate active amino agents but also help in the conservation of our finite fossil carbon resources and contribute to the reduction of CO2 emission. Herein the development of a novel 2-(4-methoxyphenyl)-1,8-naphthyridine-based iridium (III) complex is reported, which exhibits excellent catalytic performance toward a new hydrogen transfer-mediated annulation reaction of 2-nitrobenzylic alcohols with alcohols and ammonia. The catalytic transformation proceeds with the striking features of good substrate and functional group compatibility, high step and atom efficiency, no need for additional reductants, and liberation of H2O as the sole by-product, which endows a new platform for direct access to valuable quinazolines. Mechanistic investigations suggest that the non-coordinated N-atom in the ligand serves as a side arm to significantly promote the condensation process by hydrogen bonding.

The prevalence of solvent effects in heterogeneous catalysis in condensed media has motivated developing quantitative kinetic, their interactions with reaction intermediates and transition states.

In a document, author is Ohkawa, Haruki, introduce the new discover.

Supramolecular graft copolymers containing a quadruple hydrogen bond motif in the main chain have been prepared by acyclic diene metathesis (ADMET) polymerization of an alpha,omega-diene monomer containing a 2,7-diamido-1,8-naphthyridine (Napy) unit. During the ADMET polymerization, a supramolecular protection strategy was applied in order to prevent naphthyridine coordination to the ruthenium catalyst. The 2-ureido-4[1H]-pyrimidinone (UPy) derivatives used as protecting groups also allowed for detection of the supramolecular graft copolymer with size exclusion chromatography. Deprotection by simple treatment with a polar solvent afforded free Napy binding sites on the main chain. Reversible grafting of UPy derivatives of various sizes onto the free poly-Napy was demonstrated by diffusion-ordered NMR experiments.

The rat fat cell beta-adrenoceptors were investigated by studying the effects of new 1,8-naphthyridine derivatives synthesized starting from 7-amino-2-chloro-3-phenyl-1,8- naphthyridine on lipolysis induced by isoprenaline, and alprenolol. Lipolysis induced by isoprenaline agonist was competitively antagonized by the 1,8-naphthyridine analogue with a 7-hydroxy-2-(4′-methoxybenzylamine)-6-nitro-3-phenyl substituent designated as 3. In contrast, 10, 50, and 100 mu m of 7-methoxy and 7-ethoxy derivatives did not modify the concentration- response curve of isoprenaline. A rightward shift of the curve was, however, observed with 50 mu m of a 7-methoxy-2-(4 methoxybenzylamine)-6-amino-3-phenyl substituent designated as 10. The selective beta 1-AR antagonist, 7-hydroxy-4-morpholinomethyl-2-piperazino-1,8-naphthyrid ine slightly reduced isoprenaline- induced lipolysis only at high doses. Alprenolol-mediated lipolytic effect was antagonized by derivative 3, 10 and the selective beta 3-AR antagonist SR 59,230A, but resistant to the selective beta 1-AR antagonist 7-hydroxy-4-morpholinomethyl- -2-piperazino-1,8-naphthyridine. The results provide preliminary pharmacological evidence for the antilipolytic effect of the newly synthesized 1,8-naphthyridine derivatives on rat fat cells. The analogues designated as 3 and 10 were the most potent antagonists of this series.

Defective metal string complex with one nickel(II) metal absent in center [Ni-8(mu(8)-N-9-2pz)(4)Cl-2](PF6)(2) (2) was obtained on the basis a pyrazine and naphthyridine-containing triamino ligand N-2-(pyrazin-2-yl)-N-7-(7-(pyrazin-2-ylamino)-1, 8-naphthyridin-2-yl)-1, 8-naphthyridine-2, 7-diamine (H3N9-2pz) (1). The small J value (J = -2.96 cm(-1)) suggests quite a weak magnetic interaction throughout the molecule of complex 2. The weak magnetic interaction in defective complex indicates that the spin exchange in metal string occurs through the metal core rather than the bridging ligands.

Novel (non-fluoroquinolone) inhibitors of bacterial type II topoisomerases (NBTIs) are an emerging class of antibacterial agents. We report an optimized series of cyclobutylaryl-substituted NBTIs. Compound 14 demonstrated excellent activity both in vitro (S. aureus MIC90 = 0.125 mu g/ mL) and in vivo (systemic and tissue infections). Enhanced inhibition of Topoisomerase IV correlated with improved activity in S. aureus strains with mutations conferring resistance to NBTIs.
