Effect of Methylation on the Photodynamical Behavior of Arylazoimidazoles: New Insight from Theoretical ab Initio Potential Energy Calculations and Molecular Dynamics Simulations.

Arylazoimidazoles are a series of azobenzene derivatives possessing the ability to undergo photoinduced trans-cis isomerization. Their isomerization quantum yields are found to be dependent on the excitation wavelength and chemical substituents. The current work investigated the ultrafast nonadiabatic decay behaviors of three arylazoimidazoles (Pai-H, Tai-H, and Tai-Me) after being photoexcited to the S and S states by means of high-level ab initio potential energy calculations and on-the-fly surface hopping dynamical simulations in gas phase to explore the effect of the methylation.

Six generations of epidermolytic palmoplantar keratoderma, associated with a KRT9 R163W mutation.

Epidermolytic palmoplantar keratoderma (EPPK) is a rare autosomal dominant skin disorder characterized by diffuse hyperkeratosis on the palms and soles. Whole-exome sequencing (WES) has become a powerful tool for the detection of rare causal variants of Mendelian disorders. However, no causal gene for EPPK in the Uygur population has been identified until now, and no treatment exists than can address the underlying pathology.

New Insight into the Photoisomerization Process of the Salicylidene Methylamine under Vacuum.

The deactivation process of salicylidene methylamine in the gas phase has been explored using static calculations (CASSCF, CASPT2, and CC2) and on-the-fly surface hopping dynamics simulations (CASSCF).

Simultaneous quantitative determination of 5-aza-2'-deoxycytidine genomic incorporation and DNA demethylation by liquid chromatography tandem mass spectrometry as exposure-response measures of nucleoside analog DNA methyltransferase inhibitors.

The epigenetic and anti-cancer activities of the nucleoside analog DNA methyltransferase (DNMT) inhibitors decitabine (5-aza-2'-deoxycytidine, DAC), azacitidine, and guadecitabine are thought to require cellular uptake, metabolism to 5-aza-2'-deoxycytidine triphosphate, and incorporation into DNA. This genomic incorporation can then lead to trapping and degradation of DNMT enzymes, and ultimately, passive loss of DNA methylation. To facilitate measurement of critical exposure-response relationships of nucleoside analog DNMT inhibitors, a sensitive and reliable method was developed to simultaneously quantitate 5-aza-2'-deoxycytidine genomic incorporation and genomic 5-methylcytosine content using LC-MS/MS.

An artificial photosynthetic model based on a molecular triad of boron dipyrromethene and phthalocyanine.

A boron dipyrromethene (BDP) unit and its monostyryl derivative (MSBDP) were introduced at the axial positions of a silicon(iv) phthalocyanine (SiPc) core. The absorption spectrum of this compound virtually covered the entire visible region (300-700 nm) and could be interpreted as a superposition of the spectra of individual components. The intramolecular photoinduced energy and charge transfer processes of this triad were studied using steady-state and time-resolved spectroscopic methods in polar and nonpolar solvents.
