Electronic Properties of Short Polynucleotides Studied Using Schottky Junctions

Deoxyribonucleic acid (DNA), the blueprint of life, has attracted recent attention concerning its potential applications in electronics. In order to realize these applications, charge transfer through the molecule has been subjected to numerous experimental and theoretical studies in the last few decades. As a result of varying experimental conditions, different electrical behaviors have been observed. The sensitive structure of DNA is influenced by extreme environmental conditions as shown in common characterization techniques. Finding a simple yet quantitative accurate method is more efficient for understanding the electronic properties of DNA. In this work, we have employed DNA-specific Schottky junctions integrated within a printed circuit board (PCB) to investigate the properties of the four nitrogenous bases of guanine (G), thymine (T), cytosine (C) and adenine (A) in short polynucleotide form. Acquisition and analysis of the current-voltage (I-V) profiles allowed measurement of selected solid-state parameters corresponding to each of the DNA polynucleotide base. While observing characteristic I-V profiles and parameters, significantly closer and higher conductive profiles were demonstrated for the purines (A and G) as compared to the highly similar profiles of the pyrimidines (T and C) which is in agreement with previous observations. The observations obtained from this work may, therefore, provide a clear conceptualization of the role of each nitrogenous base in charge transfer process through the DNA molecule and allow better understanding of the fingerprinting electronic properties of each base.

RNA Metabolism Guided by RNA Modifications: The Role of SMUG1 in rRNA Quality Control

RNA modifications are essential for proper RNA processing, quality control, and maturation steps. In the last decade, some eukaryotic DNA repair enzymes have been shown to have an ability to recognize and process modified RNA substrates and thereby contribute to RNA surveillance. Single-strand-selective monofunctional uracil-DNA glycosylase 1 (SMUG1) is a base excision repair enzyme that not only recognizes and removes uracil and oxidized pyrimidines from DNA but is also able to process modified RNA substrates. SMUG1 interacts with the pseudouridine synthase dyskerin (DKC1), an enzyme essential for the correct assembly of small nucleolar ribonucleoproteins (snRNPs) and ribosomal RNA (rRNA) processing. Here, we review rRNA modifications and RNA quality control mechanisms in general and discuss the specific function of SMUG1 in rRNA metabolism. Cells lacking SMUG1 have elevated levels of immature rRNA molecules and accumulation of 5-hydroxymethyluridine (5hmU) in mature rRNA. SMUG1 may be required for post-transcriptional regulation and quality control of rRNAs, partly by regulating rRNA and stability.

O-4-Acetylamino-benzenesulfonylated pyrimidine derivatives: synthesis, SC-XRD, DFT analysis and electronic behaviour investigation

Beginning with 2-amino-6-methyl-pyrimidin-4-ol and 2,6-diamino-pyrimidin-4-ol, 2-amino-6-methylpyrimidin-4-yl 4-acetamidobenzenesulfonate (APABS) and 2,6-diaminopyrimidin-4-yl 4-acetamidobenzenesulfonate (DPACS) were synthesized respectively through O-4-acetylaminobenzenesulfonylation reaction. The structures of the (APABS) and (DPACS) were verified unambiguously by the single crystal X-ray diffraction technique. The X-ray diffraction inspection inferred that these chemical architectures are stabilized by intermolecular attractive forces. The quantum chemical examination of optimized geometry, vibraional analysis and natural bond orbitals (NBOs) properties for APABS and DPACS were attained by adopting B3LYP/6-311G(d,p) level. Moreover, the frontier molecular orbitals (FMOs) analysis was determined by TD-DFT/B3LYP/6-311G(d,p) level. The simulated structural parameters and XRD results of APABS and DPACS were found in close agreement to that of concerned experimental findings. The molecular stability owing to strongest hyperconjugative interactions in APABS and DPACS was evaluated through NBO investigation. The transfer of charge phenonmenon in the entitled compounds was evaluated by FMOs. The increasing order of energy gap for compounds is APABSElectric Literature of 20980-22-7, Each elementary reaction can be described in terms of its molecularity, the number of molecules that collide in that step.

Efficacy of Combination Chemotherapy Using a Novel Oral Chemotherapeutic Agent, FTD/TPI, with Ramucirumab Murine Version DC101 in a Mouse Syngeneic Cancer Transplantation Model

Trifluridine/tipiracil (FTD/TPI) (a.k.a. TAS-102) is a combination drug for metastatic colorectal cancer (CRC) and severely pretreated metastatic gastric/gastroesophageal junction (GEJ) cancers, comprising FTD, a thymidine-based antineoplastic nucleoside analog, and TPI, which enhances FTD bioavailability. Herein, in KRAS mutant murine colorectal cancer CT26 syngeneic models, we investigate whether combination therapy with DC101 (a surrogate ramucirumab antibody, rat antimouse vascular endothelial growth factor receptor (VEGFR)-2 monoclonal antibody (mAb)) improves FTD/TPI efficacy. Tumor growth inhibition (TGI) on day 15 was 38.0% and 30.6% upon DC101 monotherapy and FTD/TPI monotherapy respectively, and 60.3% upon combination therapy. Tumor volume was significantly lower (p < 0.001) upon combination treatment than upon FTD/TPI or DC101 monotherapy, indicating the additive effects of FTD/TPI and DC101. DNA-incorporated FTD levels on Day 8 were significantly higher in combination therapy with FTD/TPI (for 5 consecutive days) and DC101 (on alternate days for 7days) than in FTD/TPI monotherapy. Furthermore, vascular endothelial cell-specific marker CD31 was downregulated in DC101-treated tumors on day 8. These results indicate that combination therapy with FTD/TPI and DC101 is a promising treatment alternative regardless of KRAS mutations. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 20980-22-7 help many people in the next few years.

Bis(benzofuran-enaminone) hybrid possessing piperazine linker: Versatile precursor for microwave assisted synthesis of bis(pyrido[2 ‘,3 ‘:3,4]pyrazolo[1,5-a]pyrimidines)

We reported herein efficient procedures for the synthesis of new piperazine-linked bis(pyrido[2′,3’:3,4]pyrazolo[1,5-a]pyrimidines) using bis(benzofuran-enaminone) hybrid as a key intermediate. For this purpose, bis(enaminone) were reacted with a new series of 3-amino-4-(thiophen-2-yl)-1H-pyrazolo[3,4-b]pyridines in pyridine under microwave irradiation at 120 degrees C for 90 min to afford the target bis(pyrimidines). In a two-steps synthetic route, bis(enaminone) was used to prepare a novel bis(3-amino-1H-pyrazolo[3,4-b]pyridine). Next, the former hybrid was reacted with two equivalents of the appropriate enaminones as well as arylidinemalononitriles in pyridine under microwave irradiation at 120 degrees C for 2 h to afford the target bis(pyrimidines). Furthermore, a mixture of bis(pyrazolopyridine) reacted with two equivalents of 1,3-diketones and beta-ketoesters in glacial acetic acid was microwave irradiated at 130 degrees C for 90 min to give bis(2,4-disubstituted pyrimidines) and bis(2-substituted pyrimidin-4(1H)-ones), respectively. The structures of the new hybrids were confirmed via considering their elemental analyses as well as their spectral data. [GRAPHICS] .

Therapeutic potential of uracil and its derivatives in countering pathogenic and physiological disorders

Uracil is one of the most notable pharmacophores in medicinal chemistry as the pyrimidine nucleobase forms an integral part of many commercial drugs. Though the name uracil is usually associated with cancer drugs, there are many uracil-based compounds which can treat different diseases when they are employed. So far, there has been no in-depth review concerning uracil drugs in the market, or in the different stages of clinical trials, including those approved or discontinued. The current work focuses on the importance of uracil and its derivatives in treating different diseases. The use of uracil compounds in treating viral infections, cancer, diabetic, thyroid and autosomal recessive disorders are discussed in the review. The mechanism of action of each uracil drug with emphasis on their structure and properties are discussed in detail. The targeted action of these drugs on sites or on the different stages of a disorder/ pathogenic life cycle are also discussed. This review encompasses uracil drugs approved as well as those in development from the 1950’s onwards. The utility of uracil in drug discovery and its association with a wide range of diseases is brought forth within this review to demonstrate its potential to a wider audience.

ASARONE-DERIVED PHENYLPROPANOIDS AND ISOQUINOLINE-DERIVED ALKALOIDS FROM THE BARK OF Duguetia pycnastera (Annonaceae) AND THEIR CYTOTOXICITIES

The phytochemical investigation of the hexane and methanol extracts from the bark of Duguetia pycnastera Sandwith (Annonaceae) afforded seven known compounds, two asarone-derived phenylpropanoids and five isoquinoline-derived alkaloids. The asarones, gamma-asarone (1-allyl-2,4,5-trimethoxybenzene) and 2,4,5-trimethoxy-styrene were isolated of the hexane extract while the aporphine alkaloids, O-methylmoschatoline, lysicamine, nornuciferidine, and guatterine N-oxide, and the benzyltetrahydroisoquinoline alkaloid, (S)-reticuline were isolated of the alkaloid fraction of the methanol extract. This is the first report of these compounds in D. pycnastera. gamma-Asarone is being reported for the first time in the Annonaceae. Nornuciferidine is described for the second time in the Annonaceae while guatterine N-oxide is the third register. The structures of the isolated compounds were established by extensive analyses using 1D and 2D NMR spectroscopy in combination with MS. The cytotoxic activity of the isolated compounds (except for nornuciferidine) was evaluated against cancer and non-cancerous cell lines, in which lysicamine was the most active compound, mainly against HL-60, HepG2, and K562 with IC50 values of 24.40, 28.86 and 38.75 mu mol L-1, respectively.

Excellency of pyrimidinyl moieties containing alpha-aminophosphonates over benzthiazolyl moieties for thermal and structural stability of stem bromelain

An efficient approach has been made for the synthesis of a series of novel di alpha-aminophosphonates by the reaction of terephthalaldehyde with various pyrimidine/benzthiazole amines and diethyl phosphite using sulfonated graphitic carbon nitride – SA@g-C3N4 as catalyst under room temperature and solvent free conditions. Later, the different effects of these newly synthesized alpha-aminophosphonates as a function of concentration gradient has been scrutinized on the thermal and structural stability of stem bromelain (SBM) through combining the results of various spectroscopic techniques like UV-vis, steady state fluorescence and circular dichroism(CD). Lastly the competitive and distinctive behaviour of alpha-aminophosphonates towards the stability of SBM has been envisaged using molecular docking simulations which suggest that nature of alpha-aminophosphonates plays a crucial role for their interactions with SBM. Molecular docking results clearly show that alpha-aminophosphonates with pyrimidine ring are having more number of hydrogen bonding interaction with amino acid residues of SBM than alpha-aminophosphonates with benzthiazolyl ring. Sequentially for thermal and structure stability of SBM, concentration of alpha-aminophosphonates plays an inexorable role and through these results it must be concluded that most of the alpha-aminophosphonates are stabilizing the SBM upto the 0.1 mM concentration.

Synthesis of Novel 2-(Pyridin-2-yl) Pyrimidine Derivatives and Study of Their Anti-Fibrosis Activity

A pyrimidine moiety exhibiting a wide range of pharmacological activities has been employed in the design of privileged structures in medicinal chemistry. To prepare libraries of novel heterocyclic compounds with potential biological activities, a series of novel 2-(pyridin-2-yl) pyrimidine derivatives were designed, synthesized and their biological activities were evaluated against immortalized rat hepatic stellate cells (HSC-T6). Fourteen compounds were found to present better anti-fibrotic activities than Pirfenidone and Bipy55 ‘ DC. Among them, compounds ethyl 6-(5-(p-tolylcarbamoyl)pyrimidin-2-yl)nicotinate (12m) and ethyl 6-(5-((3,4-difluorophenyl)carbamoyl)pyrimidin-2-yl)nicotinate (12q) show the best activities with IC50 values of 45.69 mu M and 45.81 mu M, respectively. Furthermore, the study of anti-fibrosis activity was evaluated by Picro-Sirius red staining, hydroxyproline assay and ELISA detection of Collagen type I alpha 1 (COL1A1) protein expression. Our study showed that compounds 12m and 12q effectively inhibited the expression of collagen, and the content of hydroxyproline in cell culture medium in vitro, indicating that compounds 12m and 12q might be developed the novel anti-fibrotic drugs.
