New Advances in Chemical Research in 2021. Chemo-enzymatic cascade processes are invaluable due to their ability to rapidly construct high-value products from available feedstock chemicals in a one-pot relay manner. 709-63-7, Name is 4-(Trifluoromethyl)acetophenone, molecular formula is , belongs to naphthyridine compound.

A novel fluorescent probe 1 has been synthesized by a microwave reaction, and its ion-binding and fluorescence-sensing properties have been investigated under different solvent conditions. The analysis results indicated that probe 1 can act as a multiple analysis probe by simply tuning the solvent. Probe 1 exhibited high selectively toward Hg2+ through fluorescence quenching in H2O/DMF. In H2O/1,4-dioxane solution, probe 1 selectively recognized and discriminated between Ag+ and Hg2+ displaying ratiometric behaviour. Moreover, probe 1 readily recognized the anion F- via the ratiometric fluorescent mode in CH3CN. Furthermore, distinct colour changes were observed under UV light, which can be seen by the naked eye and thus used for distinguishing Hg2+, Ag+ and F- from the other ions screened herein using probe 1. Interestingly, almost pure white light emission was evident by simply tuning the F- anion-concentration, which makes this system a potential candidate for smart and tunable luminescent materials.

A number of case studies have been specifically discussed, such as the case of the naphthyridine scaffold, discovered through a structure-based virtual screening (SBVS) and proposed as the starting point for further lead optimization process, to enhance its telomeric RNA selectivity. Another example is the case of Liphagal, a tetracyclic meroterpenoid extracted from Aka coralliphaga, known as PI3K alpha inhibitor, provide an evidence for the design of new active congeners against PI3K alpha using molecular dynamics (MD) simulations. These are only two of the numerous examples of the computational techniques’ powerful in drug design and drug discovery fields.

Chemical Research Letters, May 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. , Application In Synthesis of 3-Hydroxy-2-naphthoic acid, 92-70-6, Name is 3-Hydroxy-2-naphthoic acid, molecular formula is C11H8O3, belongs to naphthyridine compound. In a document, author is Guo, Ying, introduce the new discover.

In this work, a detailed study of the structural, electronic and absorption properties of crystalline 1-ethyl-1,4-dihydro-7-methyl-4-oxo-1,8-naphthyridine-3-carboxylic acid (nalidixic acid) in the pressure range 0-300 GPa is performed by density functional theory (DFT) calculations. The detail analysis of the variation tendencies of the lattice constants, bond lengths and bond angles with increasing pressures shows that complex transformations occur in nalidixic acid under compression. In addition, it can be see that the a-and c-axes are much stiffder than the b-direction in the structure of nalidixic acid, suggesting the crystal is anisotropic. In the pressure range 90-250 GPa, repeated formations and disconnections of covalent bonds between C6 (P1 or P4) and O1 (P4 or P1) occur several times, and a new eight-atom ring forms at 90, 160, 190 and 230 GPa, respectively. Then, the analysis of the bandgap and density of states (DOS) of nalidixic acid indicates that its electronic character changes at 230 GPa into an excellent insulator, but the electron transition is much easier at several pressure regions for the bandgap closing to 0eV. Moreover, as the pressure increases relatively high optical activity of nalidixic acid is seen from the absorption spectra, and two obvious structural transformations are also observed at 200 and 230 GPa, respectively.

The blue light-emitting pyrazolo[3,4-h][1,6]naphthyridines has been synthesized by Friedlander condensation of 4-amino-3-(4-phenyl)-1-phenyl-1H-pyrazolo[3,4-b]pyridine-5-carbaldehyde (o-aminoaldehyde) 1 with different cyclic ketones and 1,3-diketones.
