Diversity-Oriented Synthesis of Thiazolidine-2-imines via Microwave-Assisted One-Pot, Telescopic Approach and Its Interaction with Biomacromolecules

In this work, a one-pot, telescopic approach is described for the combinatorial library of thiazolidine-2-imines. The synthetic manipulation proceeds smoothly via the reaction of 2-aminopyridine/pyrazine/pyrimidine with substituted isothiocyanates followed by base catalyzed ring closure with 1,2-dibromoethane to obtain thiazolidine-2-imines with broad substrate scope and high functional group tolerance. The synthetic strategy merges well with the thiourea formation followed by base catalyzed ring closure reaction for the thiazolidine-2-imine synthesis in a more modular and straightforward approach. The synthetic procedure reported herein represents a cleaner route toward thiazolidine-2-imines as compared to traditional methodologies. Moreover, the biological significance of combinatorially synthesized thiazolidin-2-imines has been investigated for their use as possible inhibitors for acetyl cholinesterase through molecular docking studies.

2 ‘-fluoro-modified pyrimidines enhance affinity of RNA oligonucleotides to HIV-1 reverse transcriptase

Nucleic acid aptamers can be chemically modified to enhance function, but modifying previously selected aptamers can have nontrivial structural and functional consequences. Wepresent a reselection strategy to evaluate the impact of several modifications on preexisting aptamer pools. RNA aptamer libraries with affinity to HIV-1 reverse transcriptase (RT) were retranscribed with 2′-F, 2′-OMe, or 2′-NH2 pyrimidines and subjected to three additional selection cycles. RT inhibition was observed for representative aptamers from several structural families identified by high-throughput sequencing when transcribed with their corresponding modifications. Thus, reselection identified specialized subsets of aptamers that tolerated chemical modifications fromunmodified preenriched libraries. Inhibition was the strongest with the 2′-F-pyrimidine (2′-FY) RNAs, as compared to inhibition by the 2’-OMeY and 2 ‘-NH2Y RNAs. Unexpectedly, a diverse panel of retroviral RTs were strongly inhibited by all 2 ‘-FY-modified transcripts, including sequences that do not inhibit those RTs as unmodified RNA. The magnitude of promiscuous RT inhibition was proportional to mole fraction 2’-FY in the transcript. RT binding affinity by 2 ‘-FY transcripts was more sensitive to salt concentration than binding by unmodified transcripts, indicating that interaction with retroviral RTs is more ionic in character for 2′-FY RNA than for unmodified 2’-OH RNA. These surprising features of 2 ‘-FY-modified RNA may have general implications for applied aptamer technologies.

Functional impacts of the ubiquitin-proteasome system on DNA damage recognition in global genome nucleotide excision repair

The ubiquitin-proteasome system (UPS) plays crucial roles in regulation of various biological processes, including DNA repair. In mammalian global genome nucleotide excision repair (GG-NER), activation of the DDB2-associated ubiquitin ligase upon UV-induced DNA damage is necessary for efficient recognition of lesions. To date, however, the precise roles of UPS in GG-NER remain incompletely understood. Here, we show that the proteasome subunit PSMD14 and the UPS shuttle factor RAD23B can be recruited to sites with UV-induced photolesions even in the absence of XPC, suggesting that proteolysis occurs at DNA damage sites. Unexpectedly, sustained inhibition of proteasome activity results in aggregation of PSMD14 (presumably with other proteasome components) at the periphery of nucleoli, by which DDB2 is immobilized and sequestered from its lesion recognition functions. Although depletion of PSMD14 alleviates such DDB2 immobilization induced by proteasome inhibitors, recruitment of DDB2 to DNA damage sites is then severely compromised in the absence of PSMD14. Because all of these proteasome dysfunctions selectively impair removal of cyclobutane pyrimidine dimers, but not (6-4) photoproducts, our results indicate that the functional integrity of the proteasome is essential for the DDB2-mediated lesion recognition sub-pathway, but not for GG-NER initiated through direct lesion recognition by XPC.

Inner shell photofragmentation of 2Cl-pyrimidine studied by mass spectrometry and electron-ion coincidence experiments

Photoelectron spectroscopy, mass spectrometry and electron-ion coincidence experiments combined with tunable synchrotron radiation have been used to study the decay and fragmentation of 2Cl-pyrimidine after Cl(2p), C(1s) and N(1s) excitations. The goal is to investigate how the state- and site-selected excitation and the chemical environment affect the fragmentation paths of the molecule and to make a comparison with fragmentation induced by direct valence ionization. It has been found that the site-selective inner shell excitation affects the branching ratio of the fragments, while the particular fragmentation channels of the cation are determined by the final state populated in the resonant decay of the core excited states. Effects of nuclear motion in the core excited states and the possible ultrafast molecular dissociation following the Cl(2p -> sigma*) core excitation are discussed.

Substitutional effects on the reactivity and thermal stability of dihydropyrimidinones

One of the advantages of dihydropyrimidinones (DHPMs) is the molecular diversity that could be achieved through their synthesis from a three-component reaction by varying the starting reaction materials. Differences in substituted functional groups could lead to varying reactivities and thermal stability amongst the analogues. In this study, two different classes of DHPMs were synthesized and the effects of the various substituents on the DHPM ring were investigated. The compounds were structurally characterized using single-crystal X-ray diffractometry, H-1, C-13, COSY, HSQC and HMBC NMR techniques, FT-IR and High Resolution Mass Spectrometry (HRMS). N1 methylation of the DHPM was found to increase the thermal stability of the series of DHPMs investigated, which is an added advantage in thermal reactions. The nature of the alkyl substituent of the ester group at position 5 of the DHPM was also found to affect the ease of the nucleophilic substitution reaction during the functionalization of the DHPMs. A complementary DFT study aided in understanding the above results as well as to compare the general stability of the range of compounds.

Substituted 2,4-Di(pyridin-2-yl)pyrimidine-Based Ruthenium Photosensitizers for Hydrogen Photoevolution under Red Light

The photocatalytic reduction of water to form hydrogen gas (H-2) is a promising approach to collect, convert, and store solar energy. Typically, ruthenium tris(bipyridine) and its many derivatives are used as photosensitizers (PSs) in a variety of photocatalytic conditions. The bis(terpyridine) analogues, however, have only recently gained attention for this application because of their poor photophysical properties. Yet, by the introduction of electron-donating or -withdrawing groups on the terpyridine ligands, the photophysical and electrochemical properties can be considerably improved. In this study, we report a series of nonsymmetric 2,6-di(pyridin-2-yl)pyrimidine ligands with peripheral pyridine substituents in different positions and their corresponding ruthenium(II) complexes. The presence of the pyrimidine ring stabilizes the lowest unoccupied molecular orbital, leading to a red-shifted emission and prolonged excited-state lifetimes as well as higher luminescence quantum yields compared to analogous terpyridine complexes. Furthermore, all complexes are easier to reduce than the previously reported bis(terpyridine) complexes used as PSs. Interestingly, the pyridine substituent in the 4-pyrimidine position has a greater impact on both the photophysical and electrochemical properties. This correlation between the substitution pattern and properties of the complexes is further investigated by using time-dependent density functional theory. In hydrogen evolution experiments under blue- and red-light irradiation, all investigated complexes exhibit much higher activity compared to the previously reported ruthenium(II) bis(terpyridine) complexes, but none of the complexes are as stable as the literature compounds, presumably because of an additional decomposition pathway of the reduced PS competing with electron transfer from the reduced PS to the catalyst.

Monomeric or dimeric? A theoretical and vibrational spectroscopic approach to the structural stability of 5-(4-metoxy benzoyl)-6-(4-metoxyphenyl)-3-methyl-2-thioxo-2,3-dihydropyrimidine-4(1H)-on

The structural and the spectral characteristics of a pyrimidine derivative, 5-(4-metoxybenzoyl)-6-(4-metoxyphenyl)-3-methyl-2-thioxo-2,3-dihydropyrimidine-4(1H)-on (BPOP) was studied using density functional theory methods (DFT/B3LYP) employing 6-31G(d), 6-31G(d,p), 6-311G(d) and 6-311G(d,p) basis sets. Two BPOP molecules form a dimeric structure linked over two mutual N-H center dot center dot center dot S=C hydrogen bonds on each of the pyrimidine rings. The quantum chemical calculations of the optimized molecular structures, the energies and IR & Raman spectra of the monomeric and the dimeric forms of BPOP have been performed. The HOMO-LUMO and the molecular electrostatic potential surface (MEP) have also been plotted. The thermodynamic functions including enthalpy, entropy and heat capacity values and Mulliken charges of both structures have been calculated. The detailed assignments of vibrational modes have been made on the basis of potential energy distribution (PED). More accurate new scaling factors were obtained for the four basis sets. It was concluded that the experimental wavenumbers are in better agreement with the results of the dimeric structures calculated by all the methods. B3LYP/6-311G(d) method regenerated the best calculated values among the others. (C) 2020 Elsevier B.V. All rights reserved.
