Evaluation of electron or charge transfer processes between chromenylium-based fluorophores and protonated-deprotonated aniline

Three functional dyes based on a chromenylium skeleton were prepared. The chromenylium-based fluorophores were regarded as acceptor parts and the aniline served as donor parts; their pH-dependent fluorescent responses were used to evaluate the photoinduce

Preparation method of tetraethyl michler's ketone

The invention relates to a preparation method of tetraethyl Michler's ketone, which comprises the following steps: carrying out acylating chlorination reaction on N, N-diethylaniline and triphosgene as raw materials in a solvent to obtain a reaction intermediate product, then taking a supported catalyst containing Lewis acid as a catalyst, and carrying out reaction on the reaction intermediate product and the N, N-diethylaniline to obtain a target reaction product, namely tetraethyl michler's ketone. Side reactions can be effectively reduced, so that the yield of the target product is increased. After the reaction is finished, the catalyst is collected through solid-liquid separation, so that the separation efficiency is high, and subsequent cyclic utilization is facilitated.

Synthesis, Identification, and Structure-Activity Relationship Analysis of GATA4 and NKX2-5 Protein-Protein Interaction Modulators

Transcription factors GATA4 and NKX2-5 directly interact and synergistically activate several cardiac genes and stretch-induced cardiomyocyte hypertrophy. Previously, we identified phenylisoxazole carboxamide 1 as a hit compound, which inhibited the GATA4-NKX2-5 transcriptional synergy. Here, the chemical space around the molecular structure of 1 was explored by synthesizing and characterizing 220 derivatives and structurally related compounds. In addition to the synergistic transcriptional activation, selected compounds were evaluated for their effects on transcriptional activities of GATA4 and NKX2-5 individually as well as potential cytotoxicity. The structure-activity relationship (SAR) analysis revealed that the aromatic isoxazole substituent in the southern part regulates the inhibition of GATA4-NKX2-5 transcriptional synergy. Moreover, inhibition of GATA4 transcriptional activity correlated with the reduced cell viability. In summary, comprehensive SAR analysis accompanied by data analysis successfully identified potent and selective inhibitors of GATA4-NKX2-5 transcriptional synergy and revealed structural features important for it.

Dimer-type triarylmethane dye compounds, blue resin composition comprising the same for color filter and color filter using the same

The present invention relates to a blue dye compound for a color filter, and more particularly, to a novel dimer-type triarylmethane dye compound having enhanced solubility, high heat resistance, high light resistance and high brightness compared to a conventional dye, and to a blue resin composition for a color filter comprising the same and a color filter using the same. When the dimer type triarylmethane dye compound according to the present invention is used in the blue resin composition for a color filter, a dye compound which has excellent solubility in propylene glycol monomethyl ether acetate (PGMEA) used as a solvent in a process and which has high heat resistance and high brightness can be provided. Therefore, a color filter with high brightness and a high contrast ratio compared to the conventional pigment type color filter can be manufactured through the manufacture of color filters using the same.(AA) Compound 6(BB) Compound 7(CC) Compound 8(DD) Compound 9(EE) Compound 10(FF) Compound 11(GG) Compound 12COPYRIGHT KIPO 2018
