SP6616 as a Kv2.1 inhibitor efficiently ameliorates peripheral neuropathy in diabetic mice

Background: Diabetic peripheral neuropathy (DPN) is a common complication of diabetes severely afflicting the patients, while there is yet no effective medication against this disease. As Kv2.1 channel functions potently in regulating neurological disorders, the present work was to investigate the regulation of Kv2.1 channel against DPN-like pathology of DPN model mice by using selective Kv2.1 inhibitor SP6616 (ethyl 5-(3-ethoxy-4-methoxyphenyl)-2-(4-hydroxy-3-methoxybenzylidene)-7-methyl-3-oxo-2,3-dihydro-5H-[1,3]thiazolo[3,2-a]pyrimidine-6-carboxylate) as a probe. Methods: STZ-induced type 1 diabetic mice with DPN (STZ mice) were defined at 12 weeks of age (4 weeks after STZ injection) through behavioral tests, and db/db (BKS Cg-m(+/+)Lepr(db)/J) type 2 diabetic mice with DPN (db/db mice) were at 18 weeks of age. SP6616 was administered daily via intraperitoneal injection for 4 weeks. The mechanisms underlying the amelioration of SP6616 on DPN-like pathology were investigated by RT-PCR, western blot and immunohistochemistry technical approaches against diabetic mice, and verified against the STZ mice with Kv2.1 knockdown in dorsal root ganglion (DRG) tissue by injection of adeno associated virus AAV9-Kv2.1-RNAi. Amelioration of SP6616 on the pathological behaviors of diabetic mice was assessed against tactile allodynia, thermal sensitivity and motor nerve conduction velocity (MNCV). Findings: SP6616 treatment effectively ameliorated the threshold of mechanical stimuli, thermal sensitivity and MNCV of diabetic mice. Mechanism research results indicated that SP6616 suppressed Kv2.1 expression, increased the number of intraepidermal nerve fibers (IENFs), improved peripheral nerve structure and vascular function in DRG tissue. In addition, SP6616 improved mitochondrial dysfunction through Kv2.1/CaMK kappa B/AMPK/PGC-1 alpha pathway, repressed inflammatory response by inhibiting Kv2.1/NF-kappa B signaling and alleviated apoptosis of DRG neuron through Kv2.1-mediated regulation of Bcl-2 family proteins and Caspase-3 in diabetic mice. Interpretation: Our work has highly supported the beneficial of Kv2.1 inhibition in ameliorating DPN-like pathology and highlighted the potential of SP6616 in the treatment of DPN.

Preparation and photocatalytic activity of pendant heteroaryl groups (pyrimidine and pyridine) grafted polyterthiophene/TiO2 composites

In this paper, new pi-conjugated heterocyclic systems with pyrimidine- and pyridine-grafted polyterthiophene were combined with TiO2 to obtain composite materials (PDTPrT/TiO2 and PDTPrmT/TiO2). The photocatalytic properties of the composites were tested by using them to degrade MB using UV-light and simulated solar irradiation. The structural analysis revealed that the pyrimidine and pyridine groups in the polyterthiophenes interacted with TiO2 via non-covalent interactions. The combination of the substituted polyterthiophene and TiO2 restrained the recombination rate of photogenerated e(-)-h(+) pairs and broadened the spectral response range of TiO2. The results indicated that PDTPrT/TiO2 and PDTPrmT/TiO2 with a TiO2-to-monomer molar ratio of 75 had the highest photodegradation rates under UV light (98.6% and 97.4%, respectively after 10 min) and simulated solar (95.4% and 92.7%, respectively after 300 min).

Intrastrand Photolesion Formation in Thio-Substituted DNA: A Case Study Including Single-Reference and Multireference Methods

The substitution of canonical nucleobases by thiated analogues in natural DNA has been exploited in pharmacology, photochemotherapy, and structural biology. Thionucleobases react with adjacent thymines leading to 6-4 pyrimidine-pyrimidone photoproducts (6-4PPs), which are a major source of DNA photodamage, in particular intrastrand cross-linked photolesions. Her; we study the mechanism responsible for the formation of 6-4PPs in thionucleobases by employing quantum-mechanical calculations. We use multiconfiguration pair-density functional theory, complete active space second-order perturbation theory, and Kohn-Sham density functional theory. Scrutinizing the photochemistry of thionucleobases can elucidate the reaction mechanism of these prodrugs and identify the role that triplet excited states play in the generation of photolesions in the natural biopolymer. Three different possible mechanisms to generate the 6-4PPs are presented, and we conclude that the use of multireference approaches is indispensable to capture important features of the potential energy surface.

The use of tissue-engineered skin to demonstrate the negative effect of CXCL5 on epidermal ultraviolet radiation-induced cyclobutane pyrimidine dimer repair efficiency

Background Ultraviolet radiation (UVR) is responsible for keratinocyte cancers through the induction of mutagenic cyclobutane pyrimidine dimers (CPDs). Many factors influence CPD repair in epidermal keratinocytes, and a better understanding of those factors might lead to prevention strategies against skin cancer. Objectives To evaluate the impact of dermal components on epidermal CPD repair efficiency and to investigate potential factors responsible for the dermal-epidermal crosstalk modulating UVR-induced DNA damage repair in keratinocytes. Methods A model of self-assembled tissue-engineered skin containing human primary keratinocytes and fibroblasts was used in this study. Results We showed that CPD repair in keratinocytes is positively influenced by the presence of a dermis. We investigated the secretome and found that the cytokine CXCL5 is virtually absent from the culture medium of reconstructed skin, compared with media from fibroblasts and keratinocytes alone. By modulating CXCL5 levels in culture media of keratinocytes, we have shown that CXCL5 is an inhibitor of CPD repair. Conclusions This work outlines the impact of the secreted dermal components on epidermal UVR-induced DNA damage repair and sheds light on a novel role of CXCL5 in CPD repair.

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.

Single-exponential solid-state delayed fluorescence decay in TADF compounds with minimized conformational disorder

Thermally activated delayed fluorescence (TADF) compounds with rapid triplet upconversion in solutions frequently yield drastically lowered upconversion rates in solid hosts due to the conformational disorder, resulting in prolonged multiexponential TADF decay profiles. The dispersion of singlet-triplet gaps was shown to be the nature of this unwanted effect, minimized in compounds with more sterically confined molecular structure, though the observation of low solid-state disorder still is scarce. Therefore, here we present the unambiguous realization of rapid single-exponential solid-state TADF decay in the optimized acridine-pyrimidine TADF compound ACRPyr. The compound was designed to have a rigid molecular structure with negligible conformational disorder along with small singlet-triplet energy gaps, leading to rapid solid-state TADF with a lifetime of about 1.76 mu s, a fluorescence quantum yield of about 0.67 and an exceptional rISC rate of 5.7 x 10(6) s(-1). Furthermore, the ACRPyr based sky-blue OLED device showed a peak EQE of 14.3% with minor roll-off.

Apoptosis, the only cell death pathway that can be measured in human diploid dermal fibroblasts following lethal UVB irradiation

Ultraviolet radiation (UVR) is a major environmental genotoxic agent. In skin, it can lead to the formation of mutagenic DNA damage. Several mechanisms are in place to prevent the conversion of these DNA damage into skin cancer-driver mutations. An important mutation prevention mechanism is the programmed cell death, which can safely dispose of the damaged cells. Apoptosis is the most studied and best characterised programmed cell death, but an increasing amount of new cell death pathways are emerging. Using different pharmacological cell death inhibitors and antioxidants, we have evaluated the implication of apoptosis, necroptosis, ferroptosis and parthanatos in UVB-induced cell death in human diploid dermal fibroblasts. Our results show that apoptosis is the only known cell death mechanism induced by UVB irradiation in fibroblasts. We also showed that lethal UVB irradiation induces a PARP-dependent drastic loss of cellular metabolic activity caused by an overused of NAD+.

Synthesis, Crystal Structure, and Photophysical Properties of 4-(4-(Dimethylamino)phenyl)-6-phenylpyrimidin-2-amine

The pyrimidine core is present in a wide variety of compounds that show interesting fluorescent properties and have been used as pigments and dyes. In this research, we synthesized 4-(4-(dimethylamino)phenyl)-6-phenylpyrimidin-2-amine (compound 9) from chalcone (8) with 45% yield. We obtained monocrystals of 9 by slow evaporation of dichloromethane as a solvent. Additionally, we measured the photophysical properties of compound 9, and its absorption wavelength (lambda(abs)), molar absorption coefficient (epsilon), excitation wavelength (lambda(exc)) and emission wavelength (lambda(em)), as well as Stokes shift (Delta lambda), increase with increasing solvent polarity. These properties are all related to the stabilization of the excited state by the solvent. On the other hand, the quantum yields (Phi values) in toluene and CH2Cl2 were notable greater than those in other solvents due to their high optical density (OD) and the decrease in the loss of fluorescence by non-radiative processes (C) 2020 Elsevier B.V.

Improving the efficiency of exciplex based OLEDs by controlling the different configurations of the donor

Two D-A-D type donor materials, 10,10 ‘-(pyridine-2,4-diyl)bis(9,9-dimethyl-9,10-dihydroacridine) (Pra-2DMAC) with vertical molecular conformation and 10,10 ‘-(pyrimidine-2,4-diyl)bis(9,9-dimethyl-9,10-dihydroacridine) (Prm-2DMAC) with near-planar molecular conformation, were designed and synthesized in order to develop the performance of exciplex based OLEDs. Pra-2DMAC shows a better performance than Prm-2DMAC, due to its vertical configuration, which has a beneficial effect on exciplex emission because the separated HOMO and LUMO in donor facilitates the intramolecular charge transfer (ICT) and reverse intersystem crossing (RISC) process at the excited state. An exciplex device with a simple structure based on Pra-2DMAC shows a high maximum external quantum efficiency (EQE) of 15.0% (13.9% at 1000 cd m(-2)), low turn-on voltage of 2.4 V, and stable electroluminescence spectrum of nearly constant CIE coordinate. The better performance of Pra-2DMAC demonstrates the superiority of the donor with vertical configurations in an exciplex system. To our knowledge, this is the first work to study exciplex based OLEDs using dual configuration donor materials.
