Experimental and theoretical studies on thymine photodimerization mediated by oxidatively generated DNA lesions and epigenetic intermediates

Interaction of nucleic acids with light is a scientific question of paramount relevance not only in the understanding of life functioning and evolution, but also in the insurgence of diseases such as malignant skin cancer and in the development of biomarkers and novel light-assisted therapeutic tools. This work shows that the UVA portion of sunlight, not absorbed by canonical DNA nucleobases, can be absorbed by 5-formyluracil (ForU) and 5-formylcytosine (ForC), two ubiquitous oxidatively generated lesions and epigenetic intermediates present in living beings in natural conditions. We measure the strong propensity of these molecules to populate triplet excited states able to transfer the excitation energy to thymine-thymine dyads, inducing the formation of cyclobutane pyrimidine dimers (CPDs). By using steady-state and transient absorption spectroscopy, NMR, HPLC, and theoretical calculations, we quantify the differences in the triplet-triplet energy transfer mediated by ForU and ForC, revealing that the former is much more efficient in delivering the excitation energy and producing the CPD photoproduct. Although significantly slower than ForU, ForC is also able to harm DNA nucleobases and therefore this process has to be taken into account as a viable photosensitization mechanism. The present findings evidence a rich photochemistry crucial to understand DNA damage photobehavior.

Photocaged 5-(Hydroxymethyl)pyrimidine Nucleoside Phosphoramidites for Specific Photoactivatable Epigenetic Labeling of DNA

5-Hydroxymethylcytosine and uracil are epigenetic nucleobases, but their biological roles are still unclear. We present the synthesis of 2-nitrobenzyl photocaged 5-hydroxymethyl-2′-deoxycytidine and uridine 3′-O-phosphoramidites and their use in automated solid-phase synthesis of oligonucleotides (ONs) modified at specific positions. The ONs were used as primers for PCR to construct DNA templates modified in the promoter region that allowed switching of transcription through photochemical uncaging.

Two white collar proteins protect fungal cells from solar UV damage by their interactions with two photolyases in Metarhizium robertsii

The photolyases PHR1 and PHR2 enable photorepair of fungal DNA lesions in the forms of UV-induced cyclobutane pyrimidine dimer (CPD) and (6-4)-pyrimidine-pyrimidone (6-4PP) photoproducts, but their regulation remains mechanistically elusive. Here, we report that the white collar proteins WC1 and WC2 mutually interacting to form a light-responsive transcription factor regulate photolyase expression required for fungal UV resistance in the insect-pathogenic fungus Metharhizum robertsii. Conidial UVB resistance decreased by 54% in Delta wc1 and 67% in Delta wc2. Five-hour exposure of UVB-inactivated conidia to visible light resulted in photoreactivation rates of 30% and 9% for the Delta wc1 and Delta wc2 mutants, contrasting to 79%-82% for wild-type and complemented strains. Importantly, abolished transcription of phr1 in Delta wc-2 and of phr2 in Delta wc1 resulted in incapable photorepair of CDP and 6-4PP DNA lesions in UVB-impaired Delta wc2 and Delta wc1 cells respectively. Yeast two-hybrid assays revealed interactions of either WC protein with both PHR1 and PHR2. Therefore, the essential roles for WC1 and WC2 in both photorepair of UVB-induced DNA lesions and photoreactivation of UVB-inactivated conidia rely upon their interactions with, and hence transcriptional activation of, PHR1 and PHR2. These findings uncover a novel WC-cored pathway that mediates filamentous fungal response and adaptation to solar UV irradiation.

Temperature-modulated selective C(sp(3))-H or C(sp(2))-H arylation through palladium catalysis

Transition metal-catalysed C-H bond functionalisations have been extensively developed in organic and medicinal chemistry. Among these catalytic approaches, the selective activation of C(sp(3))-H and C(sp(2))-H bonds is particularly appealing for its remarkable synthetic versatility, yet it remains highly challenging. Herein, we demonstrate the first example of temperature-dependent selective C-H functionalisation of unactivated C(sp(3))-H or C(sp(2))-H bonds at remote positions through palladium catalysis using 7-pyridyl-pyrazolo[1,5-a]pyrimidine as a new directing group. At 120 degrees C, C(sp(3))-H arylation was triggered by the chelation of a rare [6,5]-fused palladacycle, whereas at 140 degrees C, C(sp(2))-H arylation proceeded instead through the formation of a 16-membered tetramer containing four 7-pyridyl-pyrazolo[1,5-a]pyrimidine-palladium chelation units. The subsequent mechanistic study revealed that both C-H activations shared a common 6-membered palladacycle intermediate, which was then directly transformed to either the [6,5]-fused palladacycle for C(sp(3))-H activation at 120 degrees C or the tetramer for C(sp(2))-H arylation at 140 degrees C with catalytic amounts of Pd(OAc)(2) and AcOH. Raising the temperature from 120 degrees C to 140 degrees C can also convert the [6,5]-fused palladacycle to the tetramer with the above-mentioned catalysts, hence completing the C(sp(2))-H arylation ultimately.

Leishmanial aspartyl-tRNA synthetase: Biochemical, biophysical and structural insights

Aminoacyl tRNA synthetases (aaRSs) are integral components of protein biosynthesis along with several non-canonical cellular processes. Inhibition studies of aaRSs presented these enzymes as promising drug targets in many pathogens, however aspartyl tRNA synthetase has not been studied in trypanosomatids despite its essentiality. Hence, full-length ORF of Leishmania donovani aspartyl tRNA synthetase (LdaspRS) was cloned and purified to homogeneity followed by molecular mass determination. The aminoacylation assay established that the purified protein performs its function optimally at physiological pH and temperature. The kinetic parameters of LdaspRS revealed the affinity of L-aspartate towards the enzyme to be very much lower than the cofactor. Our study also highlights the moonlighting function of LdaspRS to stimulate the pro-inflammatory cytokines and nitric oxide generation by host macrophage. Furthermore, CD and intrinsic tryptophan fluorescence measurements showed the changes in structural conformation at varying pH, denaturants and ligands. The modelled LdaspRS structure presented all the specific characteristics of class II aaRSs, while in silico study suggested binding of pyrimidine-derived inhibitors in its cofactor binding site with high affinity followed by validation using MD simulation. Altogether, this study could provide a platform for exploring LdaspRS to develop potential therapeutics against leishmaniasis. (C) 2020 Elsevier B.V. All rights reserved.

Selective detection of fluoride and hydrogen sulfate anions by pyrimidine-based fluorescence chemosensor

The binding and sensing abilities of pyrimidine based fluorescence chemosensor L towards different anions such as F-, Cl-, Br-,I- (-), NO3-, ClO4-, H2PO4- and HSO4- have been examined by fluorescence spectroscopy in DMSO-H2O (7: 3, v/v). Upon successive addition of various anions to DMSO-H2O solutions of L; quenching in emission fluorescence is observed at 480 mu. Analysis of fluorescence emission changes suggested the formation of 1:1 complex of L with the anions. From the fluorescence binding constant data, it is found that L form strong complexes with F- and HSO4- ions through H-bonding interactions. The selective response of F- over other halides and HSO4- amongst other oxo-anions towards L may be explained on the basis of photo-induced electron transfer process.

Non-metabolic role of UCK2 links EGFR-AKT pathway activation to metastasis enhancement in hepatocellular carcinoma

Up-regulation of Uridine-cytidine kinase 2 (UCK2), a rate-limiting enzyme of the pyrimidine salvage pathway, has been suggested in HCC, but the detailed molecular mechanisms and therapic role of UCK2 remain elusive. Bioinformatic analyses revealed that UCK2 might be a key up-regulated metabolic gene in HCCs. The expressional pattern and prognostic value of UCK2 were further examined in a large number of clinical samples. Functional assays based on site-directed mutagenesis showed that UCK2 promoted cell proliferation in a metabolic manner, but non-catalytically facilitates HCC metastasis. Mechanistically, in response to EGF, UCK2 interacted with EGFR to block EGF-induced EGFR ubiquitination and degradation, which resulted in elevated EGFR-AKT pathway activation and metastasis enhancement in HCCs. Concurrent pharmacological targeting on UCK2 and EGFR showed synergistic effects on HCC treatment. This study disclosed the non-metabolic role of UCK2 and suggested the therapeutic potential of concurrent blocking the metabolic and non-metabolic roles of UCK2 in HCC treatment.
