145 Citations | This arrangement of aryl rings with respect to the porphyrin macrocycle underscores the fact that the steric barrier to rotation between the porphyrin and arylethynyl-phenyl aromatic systems has been removed and highlights the enha... |
13 Citations | The results are discussed and it is suggested that the reactive intermediate in the arylations is the phenyl diradical cation. |
| Since there is no spectral evidence for a second species, phenyl nitrene is thought the chain propagator in the autocatalytic chain decomposition that occurs for phenyl azide and for phenyl isocyanate. | |
64 Citations | The difference is ascribed to the presence in PET of a phenyl ring, which protects the ester group by various mechanisms. |
| The results reveal that the phenyl group significantly affects the molecular and electronic structures, charge distribution and phosphorescent properties. | |
54 Citations | These results demonstrate that arginine weakens hydrophobic interactions between IL-6 and the phenyl-sepharose. |
12 Citations | A direct intramolecular crosslink between neighbouring phenyl rings is shown to be the most probable modification. |
23 Citations | However, an additional phenyl moiety in position A is able to compensate at least partially the unfavorable effects of the phenyl moiety in position C. |
83 Citations | It is suggested that this is due to the basic properties of the phenyl groups. |

What is the state of art of the aryl hydrocarbon receptor chemical research?5 answersThe aryl hydrocarbon receptor (AhR) is a transcription factor that plays a crucial role in health and diseases. It is involved in the metabolism of xenobiotic ligands and has been found to be a potential target in various cancers, autoimmune disorders, and inflammatory diseases. AhR has been shown to be directly involved in biochemical pathways that influence host homeostasis, chronic disease development, and responses to toxic insults. Recent studies have also highlighted the contribution of AhR to the proper functioning of the immune, hepatic, cardiovascular, vascular, and reproductive systems. AhR regulates the expression of many genes and is closely related to epigenetics, making it a valuable tool as a diagnostic marker and therapeutic target in human pathologies. The activation of AhR can be initiated by binding to various ligands, both endogenous and exogenous, which modulate its functions. Understanding the mode of action of AhR agonists/antagonists is essential for developing therapeutic agents targeting AhR.
What is the state of art of the aryl hydrocarbon receptor research?5 answersThe state of art of aryl hydrocarbon receptor (AhR) research is focused on understanding its structure, regulation, physiological role, and ligands. AhR is a transcription factor belonging to the bHLH-PAS family and is involved in various diseases and health conditions. It has been traditionally associated with xenobiotic metabolism, but recent studies have identified diverse ligands including amino acid metabolites, polyphenols, and polychlorinated biphenyls. AhR has emerged as a promising target in cancer, autoimmune disorders, and inflammatory diseases. Research has also explored the therapeutic potential of AhR agonists and antagonists in cancer treatment. Computational models have been used to study the interaction of AhR with different ligands, providing insights into its binding process. AhR has been found to regulate gene expression through transcription-dependent mechanisms and epigenetic processes. Overall, AhR research aims to uncover its role in cell physiology, organ homeostasis, and human diseases.
What are phenylpropanoids?5 answersPhenylpropanoids are a class of plant secondary metabolites that are widely present in various plant sources such as fruits, vegetables, cereal grains, beverages, spices, and herbs. They have diverse biological activities including antimicrobial, antioxidant, anti-inflammatory, antidiabetic, anticancer, renoprotective, neuroprotective, cardioprotective, and hepatoprotective effects. Phenylpropanoids consist of a six-carbon aromatic phenyl group and a three-carbon propane side chain, and they can be categorized into three main groups: flavonoids, monolignols, and phenolic acids. These compounds play important roles in plants as antibiotics, natural pesticides, signal molecules, attractants for pollinators, protective agents against UV light, and structural materials. In addition, phenylpropanoids possess potent antioxidant properties and can act as reducing agents, hydrogen donors, radical scavengers, singlet oxygen quenchers, and metal chelators. Due to their antioxidant properties, phenylpropanoids have potential applications in various industries such as food, pharmaceutical, cosmetic, textile, biofuel, and sensors.
What are the different classifications of aromatic compounds?5 answersAromatic compounds can be classified into three groups: alkyl-, aryl-, and alicyclic-substituted benzene derivatives, di- and polyphenyls, and polycyclic compounds composed of two or more fused benzene ring systems. Another classification includes monosubstituted benzenes named as derivatives of benzene, disubstituted benzenes using the ortho/meta/para system and the numerical system, and more highly substituted benzenes named using numbers. The chemistry of aromatic compounds has also evolved to include novel classes such as charged species, nonclassical aromatics, and fullerenes. Compounds with specific structures, such as those containing perylene, fluoranthene, chrysene, pyrene, or triphenylene, are also classified as aromatic. Additionally, compounds with the structure mentioned in the abstract are considered aromatic.
What is mechanism of acid hydrolysis of benzyl phenyl ether?5 answersThe acid-catalyzed hydrolysis of benzyl phenyl ether occurs through a bimolecular nucleophilic substitution reaction in mixtures of water and aprotic solvents. In aqueous acetic acid solutions, the hydrolysis mechanism can be either bimolecular or unimolecular, depending on the structure of the ether and the solvent composition. The hydrolysis of benzyl phenyl ether in neutral to moderate alkaline solutions follows a dissociative (E1cB) route, involving ionization of the amino group and unimolecular expulsion of the leaving group from the ionized ester. In more alkaline solutions, further ionization of the conjugate base of the ester occurs, leading to the formation of a dianionic species that expels the aryloxide leaving group. The acid-catalyzed hydrolysis of benzyl phenyl ether is generally acid-catalyzed in acidic media, while a different mechanism operates in neutral solutions.
