Novel insights into the roles of RNA N-6-methyladenosine modification in regulating gene expression during environmental exposures

N-6-methyladenosine (m(6)A) is one of the most common RNA modifications in eukaryotes involved in the regulation of post-transcriptional gene expression, as well as the occurrence and development of diseases related to environmental exposures. Adverse factors produced by environmental exposures, such as reactive oxygen species, inflammation, and cyclobutane pyrimidine dimers, mediate m(6)A modification, thereby regulating downstream gene and protein expression, and signaling pathways, such as FTO/m(6)A RNA/p53 axis, PI3K/AKT/mTOR pathway, and PARP/METTL3/m(6)A RNA/Pol kappa pathway. Moreover, an imbalance in m(6)A methylation levels directly mediates disease pathogenesis. To date, some studies have detailed the mechanisms underlying environmental exposure-mediated global changes in RNA m(6)A methylation. Based on our current understanding, we aimed to elaborate on the molecular mechanisms through which RNA m(6)A methylation regulates gene expression under environmental exposures. In this review, we outline the biogenesis and functions of RNA m(6)A modification. Furthermore, we focus on the effects of environmental exposures on m(6)A levels and highlight the relationships between environmental exposures (doses and time) and m(6)A levels. Although the molecular mechanisms regulating gene expression remains to be elucidated, m(6)A has potential applications as a disease biomarker. (C) 2020 Elsevier Ltd. All rights reserved.

Ultrafast excited-state dynamics of promising nucleobase ancestor 2,4,6-triaminopyrimidine

The ultrafast excited-state dynamics of 2,4,6-triaminopyrimidine – thought to be a promising candidate for a proto-RNA nucleobase – have been investigated via static multireference quantum-chemical calculations and mixed-quantum-classical/trajectory surface-hopping dynamics with a focus on the lowest-lying electronic states of the singlet manifold and with a view towards understanding the UV(C)/UV(B) photostability of the molecule. Ultrafast internal conversion channels have been identified that connect the lowest-lying pi pi* electronically-excited state of 2,4,6-triaminopyrimidine with the ground electronic state, and non-radiative decay has been observed to take place on the picosecond timescale via a pi pi* out-of-plane NH2 (oop-NH2) minimum-energy crossing point. The short excited-state lifetime is competitive with the excited-state lifetimes of the canonical pyrimidine nucleobases, affirming the promise of 2,4,6-triaminopyrimidine as an ancestor. Evidence for energy-dependent excited-state dynamics is presented, and the open question of intersystem crossing is discussed speculatively.

[1,2,4]Triazolo[1,5-a]pyrimidine Phosphodiesterase 2A Inhibitors: Structure and Free-Energy Perturbation-Guided Exploration

We describe the hit-to-lead exploration of a [1,2,4]triazolo[1,5-a]pyrimidine phosphodiesterase 2A (PDE2A) inhibitor arising from high-throughput screening. X-ray crystallography enabled structure-guided design, leading to the identification of preferred substructural components. Further rounds of optimization used relative binding free-energy calculations to prioritize different substituents from the large accessible chemical space. The free-energy perturbation (FEP) calculations were performed for 265 putative PDE2A inhibitors, and 100 compounds were synthesized representing a relatively large prospective application providing unexpectedly active molecules with IC50’s from 2340 to 0.89 nM. Lead compound 46 originating from the FEP calculations showed PDE2A inhibition IC50 of 1.3 +/- 0.39 nM, similar to 100-fold selectivity versus other PDE enzymes, clean cytochrome P450 profile, in vivo target occupancy, and promise for further lead optimization.

A study on the interaction of nile blue with Uracils: A spectroscopic and computational approach

The present work focuses the investigation on fluorescence quenching of nile blue (NB) in presence of various substituted uracil molecules. UV-Visible absorption studies signify the possibility of ground state complex forma-tion between NB and uracil molecules. The increase in concentration of quencher molecules greatly influences the emission spectra of NB. The bimolecular quenching rate constant (k(q)) were calculated and found to depend on the position and electronic properties of substituent in quencher molecules. Fluorescence quenching experiments were performed at different temperature to calculate the thermodynamic parameters. The fluorescence lifetime measurements show that the quenching process proceeds through static quenching. The mechanism of fluorescence quenching includes the possibility of proton transfer. The bond dissociation enthalpy (BDE) reveals the release of H center dot from the quencher molecules. The quencher molecules possess antioxidant activity and identified using deoxyribose degradation assay. The position of substituent and its electronic property are key features to address the antioxidant activity of uracil molecules. (c) 2020 Elsevier B.V. All rights reserved.

Evaluation of the Structure-Activity Relationship of Microtubule-Targeting 1,2,4-Triazolo[1,5-a]pyrimidines Identifies New Candidates for Neurodegenerative Tauopathies

Studies in tau and A beta plaque transgenic mouse models demonstrated that brain-penetrant microtubule (MT)-stabilizing compounds, including the 1,2,4-triazolo[1,5-a]-pyrimidines, hold promise as candidate treatments for Alzheimer’s disease and related neurodegenerative tauopathies. Triazolopyr-imidines have already been investigated as anticancer agents; however, the antimitotic activity of these compounds does not a always correlate with stabilization of MTs in cells. Indeed, previous studies from our laboratories identified a critical role for the fragment linked at C6 in determining whether triazolopyrimidines promote MT stabilization or, conversely, disrupt MT integrity in cells. To further elucidate the structure-activity relationship (SAR) and to identify potentially improved MT stabilizing candidates for neurodegenerative disease, a comprehensive set of 68 triazolopyrimidine congeners bearing structural modifications at C6 and/or C7 was designed, synthesized, and evaluated. These studies expand upon prior understanding of triazolopyrimidine SAR and enabled the identification of novel analogues that, relative to the existing lead, exhibit improved physicochemical properties, MT-stabilizing activity, and pharmacokinetics.

Cyclobutane pyrimidine dimers from UVB exposure induce a hypermetabolic state in keratinocytes via mitochondrial oxidative stress

Ultraviolet B radiation (UVB) is an environmental complete carcinogen, which induces and promotes keratinocyte carcinomas, the most common human malignancies. UVB induces the formation of cyclobutane pyrimidine dimers (CPDs). Repairing CPDs through nucleotide excision repair is slow and error-prone in placental mammals. In addition to the mutagenic and malignancy-inducing effects, UVB also elicits poorly understood complex metabolic changes in keratinocytes, possibly through CPDs. To determine the effects of CPDs, CPD-photolyase was overexpressed in keratinocytes using an N1-methyl pseudouridine-containing in vitro-transcribed mRNA. CPD-photolyase, which is normally not present in placental mammals, can efficiently and rapidly repair CPDs to block signaling pathways elicited by CPDs. Keratinocytes surviving UVB irradiation turn hypermetabolic. We show that CPD-evoked mitochondrial reactive oxygen species production, followed by the activation of several energy sensor enzymes, including sirtuins, AMPK, mTORC1, mTORC2, p53, and ATM, is responsible for the compensatory metabolic adaptations in keratinocytes surviving UVB irradiation. Compensatory metabolic changes consist of enhanced glycolytic flux, Szent-GyOrgyi-Krebs cycle, and terminal oxidation. Furthermore, mitochondrial fusion, mitochondrial biogenesis, and lipophagy characterize compensatory hypermetabolism in UVB-exposed keratinocytes. These properties not only support the survival of keratinocytes, but also contribute to UVB-induced differentiation of keratinocytes. Our results indicate that CPD-dependent signaling acutely maintains skin integrity by supporting cellular energy metabolism.

Design, Synthesis and Biological Evaluation of New Pyrimidine Derivatives as Anticancer Agents

Background: Anticancer drug resistance is a challenging phenomenon of growing concern which arises from alteration in drug targets. Despite the fast speed of new chemotherapeutic agent design, the increasing prevalence of this phenomenon requires further research and treatment development. Recently, we reported a new aminopyrimidine compound-namely RDS 344-as a potential innovative anticancer agent. Methods: Herein, we report the design, synthesis, and anti-proliferative activity of new aminopyrimidine derivatives structurally related to RDS 3442 obtained by carrying out substitutions at position 6 of the pyrimidine core and/or on the 2-aniline ring of our hit. The ability to inhibit cell proliferation was evaluated on different types of tumors, glioblastoma, triple-negative breast cancer, oral squamous cell carcinomas and colon cancer plus on human dermal fibroblasts chosen as control of normal cells. Results: The most interesting compound was the N-benzyl counterpart of RDS 3442, namely 2a, that induced a significant decrease in cell viability in all the tested tumor cell lines, with EC(50)s ranging from 4 and 8 mu M, 4-13 times more active of hit. Conclusions: These data suggest a potential role for this class of molecules as promising tool for new approaches in treating cancers of different histotype.

Chemically functionalized of 8-hydroxyquinoline derivatives as efficient corrosion inhibition for steel in 1.0 M HCl solution: Experimental and theoretical studies

The challenge of this work is the functionalization of new 8-hydroxyquinoline derivatives by a simple method achieving a very good yield (80-90%).The corrosion inhibition performance of two neworganic compounds derived from quinolin-8-ol, namely, BMQ and DEMQ for mild steel in 1.0 M HCl solution was studied usingPotentiodynamic polarization (PDP)and electrochemical impedance spectroscopy (EIS).Scanning electron microscopy (SEM) coupled with the energy dispersive spectroscopy (EDX) were used to characterize and analyze the surface of steel.The theoretical study wasalso carried out by DFT calculations (structure-reactivity) and Monte Carlo, MC (inhibitor-surface) simulations. The electrochemical results showed that both studied molecules provide high resistance and that the inhibition efficiency (eta%) reaches 94% at 10(-3) M for BMQ. PDP measurements revealed that these compounds function as mixed type corrosion inhibitors. In addition, they can be adsorbed on the steel surface by chemical bonds following Langmuir adsorption isotherm. Also, both inhibitors remain effective at high temperatures (86% at 328 K for the concentration 10(-3) M).DFT calculations show that the free heteroatom doublets of oxygen (O), nitrogen (N) and the methyl groups (-CH3) favor the sharing of electrons between the studiedmolecules and the surface of the steel. The data of theoretical methods (DFT and MC) supported the experimental findings.
