Photophysics of 9,9-Dimethylacridan-Substituted Phenylstyrylpyrimidines Exhibiting Long-Lived Intramolecular Charge-Transfer Fluorescence and Aggregation-Induced Emission Characteristics

Six pyrimidine-based push-pull systems substituted at positions C2 and C4/6 with phenylacridan and styryl moieties, employing methoxy or N,N-diphenylamino donors, have been designed and synthesized through cross-coupling and Knoevenagel reactions. X-ray analysis confirmed that the molecular structure featured the acridan moiety arranged perpendicularly to the residual pi system. Photophysical studies revealed significant differences between the methoxy and N,N-diphenylamino chromophores. Solvatochromic studies revealed that the methoxy derivatives showed dual emission in polar solvents. Time-resolved spectroscopy revealed that the higher energy band involved very fast (<80 ps) fluorescence, whereas the lower energy one included long components (approximate to 30 ns) due to long-lived intramolecular charge-transfer fluorescence. In contrast to N,N-diphenylamino chromophores, the methoxy derivatives also showed aggregation-induced emission in mixtures of THF/water, as well as dual emission in thin films, covering almost the whole visible spectrum with corresponding chromaticity coordinates not far from that of pure white light. These properties render the methoxy derivatives as very promising organic materials for white organic light-emitting diodes.

Fluorescent molecular rotors as sensors for the detection of thymidine phosphorylase

Three new fluorescent molecular rotors were synthesized with the aim of using them as sensors to dose thymidine phosphorylase, one of the target enzymes of 5-fluorouracil, a potent chemotherapic drug largely used in the treatment of many solid tumors, that acts by hindering the metabolism of pyrimidines. 5-Fluorouracil has a very narrow therapeutic window, in fact, its optimal dosage is strictly related to the level of its target enzymes that vary significantly among patients, and it would be of the utmost importance to have an easy and fast method to detect and quantify them. The three molecular rotors developed as TP sensors differ in the length of the alkylic spacer joining the ligand unit, a thymine moiety, and the fluorescent molecular rotor, a [4-(1-dimethylamino)phenyl]-pyridinium bromide. Their ability to trigger an optical signal upon the interaction with thymidine phosphorylase was investigated by fluorescent measurements.

Synthesis of New Polyheterocyclic Ring Systems Derived from 3-Amino-5-bromo-4,6-dimethyl-1H-pyrazolo[3,4-b]pyridine

3-Amino-5-bromo-4,6-dimethyl-1H-pyrazolo[3,4-b]pyridine (2) was utilized as a precursor for the construction of new polyheterocyclic ring systems. It reacted with 4-substituted arylidene malononitriles and/or ethyl acetoacetate to furnish the corresponding pyrido[2′,3′:3,4]pyrazolo[1,5-a]pyrimidine derivatives 4a-c and 6, respectively. Diazotization of the precursor 2 followed by coupling with ethyl cyanoacetate was the route for the formation of pyrido[2′,3′:3,4]pyrazolo[5,1-c]triazine derivative 8. The synthesized N-(5-bromo-4,6-dimethyl-1H-pyrazolo[3,4-b]pyridin-3-yl)-2-cyanoacetamide (10) was utilized for the synthesis of 6-amino-4-aryl-1-(pyrazolo[3,4-b]-pyridin-3-yl)-1,2-dihydropyridines derivatives 12a-c via its treatment with three types of arylidene malononitrile. N-(5-Bromopyrazolo[3,4-b]pyridinyl)-2-(4-oxothiazolidin-2-ylidene)acetamide 13 and N-(5-bromopyrazolo[3,4-b]pyridinyl)-2-cyano-2-(4-oxo-3-phenylthiazolidin-2-ylidene)acetamide 15 were picked up through the reactions of 10 with 2-mercaptoacetic acid and/or Ph-N = C = S with BrCH2COOEt. The tricyclic ring system, 9-bromo-3-cyano-2-oxo-pyrido[2′,3′:3,4]pyrazolo[1,5-a]-pyrimidine derivative 18, was used as building block for the construction of new tetra- and penta-heterocyclic compounds 19, 20, and 21 through its reaction with some bis-nucleophilic reagents; hydrazine hydrate, malononitrile and 4-(4-anisylazo)-1H-pyrazole-3,5-diamine. The newly synthesized pyrazolo[3,4-b]pyridine-based heterocycles were characterized by the IR and H-1 NMR spectral techniques and their in vitro antibacterial properties were evaluated.

Synthesis of C-nucleoside analogues based on the pyrimidine skeleton for the formation of anti-parallel-type triplex DNA with a CG mismatch site

The triplex DNA forming method is an attractive tool as a gene-targeting agent. Using artificial nucleoside analogues based on C-nucleoside, stable and selective triplex DNA can be formed in a specific region of duplex DNA, and its biotechnology applications will greatly expand. In this study, we designed and synthesized novel C-nucleoside analogues based on the pyrimidine skeleton, (3Me)AP-d(Y-Cl) and (3Me)AP-d(Y-H), capable of recognizing a CG mismatch site that is not recognized by natural nucleosides. After incorporating them into the oligonucleotides, their triplex forming abilities were evaluated by gel-shift assay. Although it was only one sequence, the 3′-GZG-5′ sequence, the stability of the CG mismatch site recognition was greatly improved compared with previous nucleoside analogues.

Luteolin alleviates inflammation and modulates gut microbiota in ulcerative colitis rats

Ulcerative colitis (UC) is a chronic inflammatory bowel disease related to intestinal dysbiosis. Luteolin has been reported to reduce inflammation. However, it remains unclear whether luteolin ameliorates UC and regulates gut microbiota. In this study, we investigated the effects of luteolin on colonic structure and inflammation of dextran sulfate sodium (DSS)-induced rats using hematoxylin-eosin staining, immunohistochemistry and enzyme-linked immunosorbent assay and evaluated the effects of luteolin on gut microbiota using 16S rDNA sequencing. We found that luteolin treatment significantly reduced colonic damage, and inhibited colonic inflammation in UC rats, evidenced by the decreased levels of NF-kappa B, IL-17 and IL-23 in UC rats and the increased level of PPAR-gamma. In addition, the 16S rDNA sequencing analysis revealed that luteolin treatment could alter diversity and composition of gut microbiota in UC rats. Lactobacillus, Bacteroides, Roseburia and Butyricicoccus were dominant genera in the luteolin group. Luteolin treatment reduced DSS-induced increased ratios of Lactobacillus and Prevotella_9. Furthermore, KEGG analysis revealed that gut microbiota was mainly related to DNA repair and recombination proteins, ribosome, purine metabolism, peptidases, and pyrimidine metabolism. In conclusion, our results revealed that luteolin could alleviate DSS-induced colitis in rats, and gut microbiota had the potential to serve as promising biomarkers for uncovering the mechanism by which luteolin improved UC.

Development of a rapid electrophoretic assay for genomic DNA damage quantification

Accuracy, sensitivity, simplicity, reproducibility, and low-cost are desirable requirements for genotoxicity assessment techniques. Here we describe a simple electrophoretic assay for genomic DNA lesions quantification (EAsy-GeL) based on subjecting DNA samples to rapid unwinding/renaturation treatments and neutral agarose gel electrophoresis. The experiments performed in this work involved different biological samples exposed to increasing environmental-simulated doses of ultraviolet-B (UVB) radiation, such as Escherichia coli, human leukocytes, and isolated human genomic DNA. DNA extraction was carried out using a universal and low-cost protocol, which takes about 4 h. Before electrophoresis migration, DNA samples were kept into a neutral buffer to detect double-strand breaks (DSBs) or subjected to a 5-min step of alkaline unwinding and neutral renaturation to detect single-strand breaks (SSBs) or incubated with the DNA repair enzyme T4-endonuclease V for the detection of cyclobutane pyrimidine dimers (CPDs) before the 5-min step of DNA unwinding/renaturation. Then, all DNA samples were separated by neutral agarose gel electrophoresis, the DNA average length of each lane was calculated through the use of free software, and the frequency of DNA breaks per kbp was determined by a simple rule of three. Dose-response experiments allowed the quantification of different levels of DNA damage per electrophoretic run, varying from a constant and low amount of DSBs/SSBs to high and dose-dependent levels of CPDs. Compared with other assays based on alkaline unwinding and gel electrophoresis, EAsy-GeL has important advantages for both environmental monitoring and laboratory testing purposes. The simplicity and applicability of this protocol to other types of DNA lesions, biological models, and agents make it ideal for genotoxicity, DNA repair studies, as well as for assessing exposure risks to ecosystems and human health.

Rigorous Computational Study Reveals What Docking Overlooks: Double Trouble from Membrane Association in Protein Kinase C Modulators

Increasing protein kinase C (PKC) activity is of potential therapeutic value. Its activation involves an interaction between the C1 domain and diacylglycerol (DAG) at intracellular membrane surfaces; DAG mimetics hold promise as new drugs. We previously developed the isophthalate derivative HMI-1a3, an effective but highly lipophilic (clogP = 6.46) DAG mimetic. Although a less lipophilic pyrimidine analog, PYR-IgP (clogP = 3.30), gave positive results in computational docking, it unexpectedly presented greatly diminished binding to PKC in vitro. Through more rigorous computational molecular modeling, we reveal that, unlike HMI-1a3, PYR-1gP forms an intramolecular hydrogen bond, which both obstructs binding and reorients PYR-1gP in the membrane in a fashion that prevents it from correctly accessing the PKC C1 domain. Our results highlight the great value of molecular dynamics simulations as a key component for the drug design process of ligands targeting weakly membrane-associated proteins, where simulation in the relevant membrane environment is crucial for obtaining biologically applicable results.
