Synthesis, biological evaluation and molecular docking studies of novel thiopyrimidine analogue as apoptotic agent with potential anticancer activity

This study synthesizes novel 6-amino-5-cyano-4-aryl-2-mercapto pyrimidines and condensed pyrimidines analogues in order to investigate their potential activity as anticancer agents. The compounds were synthesized via one-pot condensation of p-nitrobenzaldehyde or p-anisaldehyde with malononitrile and thiourea to prepare 6amino-5-cyano-4-aryl-2-mercaptopyrimidines series (1-9a,b). The pyrimidine analogues were biologically screened In-vitro in HepG2 and MCF-7 compared to normal WI-38. Compound 8a showed higher anti proliferative activity to MCF-7 cells with sensitivity and minimal cytotoxic effect (IC50 53.3 mu MHepG2, 12.9 mu MMCF-7 and > 100 mu MWI-38). Compound 8a was able to induce 40% of total antioxidants and 60% following treatment with 50 mu M of H2O2 for 3hrs as external source of oxidative stress in MCF-7. 8a was able to significantly induce early stage apoptosis of 74.37% MCF-7 and cell cycle arrest with cells accumulation in subG0-G1 phase to 69.42% and reduction of cells in G2M phase to 3.6% and high apoptotic index. Compound 8a induced over-expression of Fas receptor and Cyto C genes. Molecular docking studies suggested that 8a can bind to both phosphodiesterase 4B and 4D binding pockets and inhibit their action through network of hydrophobic interactions in Q-P pockets with preferential selectivity to PDE4B through invariant Glu443. The chemical profile and the biological results suggest that 8a can be a promising anticancer agent.

The multienzymatic protein CAD leading the de novo biosynthesis of pyrimidines localizes exclusively in the cytoplasm and does not translocate to the nucleus

CAD, the multienzymatic protein that initiates and controls the de novo biosynthesis of pyrimidines, plays a major role in nucleotide homeostasis, cell growth and proliferation. Despite its interest as a potential antitumoral target, there is a lack of understanding on CAD’s structure and functioning mechanisms. Although mainly identified as a cytosolic complex, different studies support the translocation of CAD into the nucleus, where it could have a yet undefined function. Here, we track the subcellular localization of CAD by using fluorescent chimeras, cell fractionation and immunoblotting with specific antibodies. Contradicting previous studies, we demonstrate that CAD is exclusively localized at the cytosol and discard a possible translocation to the nucleus.

Time-course transcriptomics reveals that amino acids catabolism plays a key role in toxinogenesis and morphology in Clostridium tetani

Tetanus is a fatal disease caused by Clostridium tetani infections. To prevent infections, a toxoid vaccine, developed almost a century ago, is routinely used in humans and animals. The vaccine is listed in the World Health Organisation list of Essential Medicines and can be produced and administered very cheaply in the developing world for less than one US Dollar per dose. Recent developments in both analytical tools and frameworks for systems biology provide industry with an opportunity to gain a deeper understanding of the parameters that determine C. tetani virulence and physiological behaviour in bioreactors. Here, we compared a traditional fermentation process with a fermentation medium supplemented with five heavily consumed amino acids. The experiment demonstrated that amino acid catabolism plays a key role in the virulence of C. tetani. The addition of the five amino acids favoured growth, decreased toxin production and changed C. tetani morphology. Using time-course transcriptomics, we created a fermentation map, which shows that the tetanus toxin transcriptional regulator BotR, P21 and the tetanus toxin gene was downregulated. Moreover, this in-depth analysis revealed potential genes that might be involved in C. tetani virulence regulation. We observed differential expression of genes related to cell separation, surface/cell adhesion, pyrimidine biosynthesis and salvage, flagellar motility, and prophage genes. Overall, the fermentation map shows that, mediated by free amino acid concentrations, virulence in C. tetani is regulated at the transcriptional level and affects a plethora of metabolic functions.

Diagnostic and prognostic value of FOXD1 expression in head and neck squamous cell carcinoma

FOXD1 has been reported to function as an oncogene in several types of cancer. This study evaluated the expression of FOXD1 and its role in head and neck squamous cell carcinoma (HNSCC). We mined the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO) databases for expression profiles, clinical significance, and potential mechanisms of FOXD1 in HNSCC. Our validation cohort consisted of FOXD1 mRNA expression in 162 paired HNSCC and adjacent normal tissues, as determined using quantitative real-time polymerase chain reaction. FOXD1 expression was upregulated in HNSCC in the public databases and in the validation cohort. The expression level of FOXD1 was associated with DNA amplification and methylation level. The areas under the curves (AUC) of TCGA cohort and the validation cohort were 0.855 and 0.843, respectively. Furthermore, higher FOXD1 expression was significantly associated with worse overall survival (hazard ratio [HR]: 1.849, 95% confidence interval [CI]: 1.280-2.670, P = 0.001) and a lower rate of recurrence-free survival (HR: 1.650, 95% CI: 1.058-2.575, P = 0.027) in patients with HNSCC. Moreover, gene set enrichment analysis showed that cases of HNSCC with FOXD1 overexpression were enriched in bladder cancer, cell cycle, DNA replication, glycosaminoglycan biosynthesis chondroitin sulfate, homologous recombination, glycan biosynthesis, nucleotide excision repair, p53 signaling pathway, pyrimidine metabolism, and spliceosome pathways. In summary, FOXD1 was significantly upregulated in HNSCC and was a good diagnostic biomarker and an independent predictor of poor survival and low rate of recurrence-free survival in patients with HNSCC.

Interrogating the Interplay between Hydrogen and Halogen Bonding in Graphitic Carbon Nitride Building Blocks

Two graphitic carbon nitride (g-C3N4) molecular building blocks designed for halogen bond driven assembly are evaluated through computational quantum chemistry. Unlike those typically reported in the literature, these g-C3N4-based acceptors each offer three unique sites for halogen bond formation, which when introduced to their donor counterparts, lead to 1:1, 2:1, and 3:1 donor-acceptor complexes. Although halogen bonding interactions are present in all donor-acceptor complexes considered in the work, intermolecular hydrogen bonding emerges in complexes in which an iodine-based donor is directly involved. The halogen bond complexes identified herein feature linear halogen bonds and supportive intermolecular hydrogen bonds that lead to nearly additive electronic binding energies of up to -9.7 (dimers), -18.6 (trimers), and -26.5 kcal mol 71 (tetramers). Select vibrational stretching frequencies (vC-x and v(C C)), and the perturbative shifts they incur upon halogen bond formation, are interrogated and compared to those observed in pyridine- and pyrimidine-based halogen-bonded complexes reported in the literature.

SYNTHESIS AND BIOLOGICAL EVALUATION OF SOME NOVEL METHYLPYRIMIDINE DERIVATIVES AS AN ANTIDIABETIC AND ANTIHYPERLIPIDEMIC AGENTS

Diabetes and hyperlipidemia become a major risk factor for cardiovascular diseases in the world. Hyperlipidemia is a relatively common problem in patients with poorly controlled diabetes. In searching for a new class of antidiabetic and antihyperlipidemic agents, many compounds with pyridine moiety have been found to possess good activity against diabetes and hyperlipidemia. The present study was carried out to synthesize, characterize, and screening of methyl pyrimidine derivatives for antidiabetic and antihyperlipidemic activity. A novel series of 2-amino-4-(substituted phenylamino)-6-methylpyrimidine derivatives have been synthesized from Guanidine hydrochloride. Synthesized compounds were characterized by IR, MASS, H-1-NMR, and C NMR spectroscopy. Synthesized compounds were screened for antidiabetic and antihyperlipidemic activity in Swiss albino mice. The blood sample was collected and used to determine serum glucose, triglyceride, LDL (low-density lipoprotein), HDL (high-density lipoprotein), and total cholesterol level in mice. Among the synthesized derivatives, 2-amino-4-(4-methoxyphenylamino)-6-methylpyrimidine and 2-amino-4-(4-bromophenylamino)6-methylpyrimidine shows good antidiabetic and antihyperlipidemic activity which was comparable to the standard drug, and it can be useful for the further clinical studies.

Effects of carbon nanomaterials on the migration and fate of organic pollutants in the ecological environment

The purpose of this study was to investigate the mechanism of adsorption reaction between heterocyclic organic compounds with different number of ring atoms and different atoms replacing carbon atoms and carbon nanotubes with different surface functional groups. Based on the current situation of research on adsorption of carbon nanomaterials adsorbing organic pollutants, the existing problems and limitations were analyzed by studying the properties and characterization of single-walled carbon nanotubes, oxidized single-walled carbon nanotubes and non-porous graphite powder, such as elemental analysis, transmission electron micrograph, zero charge point, etc. The three adsorption materials were investigated by batch experiment. Six compounds of thiophene, pyrimidine, benzene, aniline, 2-aminopyrimidine and 4,6-diaminopyrimidine were selected as the adsorbate for detecting adsorption capacity. The results showed that the affinity of different adsorbents on different adsorbents varied greatly. The adsorption capacity of heterocyclic compounds containing N and S was greatly enhanced by non-hydrophobic action. And the degree of oxidation of the adsorbent and the ph of the solution determined the adsorption capacity of the adsorbent for nitrogen-containing heterocyclic compounds. Therefore, in the ecological environment, the migration of hydrophilic organic pollutants in the environment can be reduced by the preparation of appropriate carbon nanotubes.

Evaluation of the cytotoxic and genotoxic effects of Sida planicaulis Cav extract using human neuroblastoma cell line SH-SY5Y

Sida planicaulis is a weed thought to have originated in Brazil, where it is present in abundant quantities, but also this plant is also found in south-central Florida, Indian Ocean Islands, and the Pacific Islands. Sida planicaulis produces neurotoxicity that adversely affects livestock breeding with heavy animal losses and consequent negative impact on Brazil’s economy. The aim of this study was to determine the chemical profile, cytotoxic and genotoxic effects of ethanolic extracts of S. planicaulis collected in winter (leaf extract) and summer (leaf extract and leaf + flower extract) using an in vitro model of human neuroblastoma cell line SH-SY5Y. Phytochemical screening demonstrated the presence of alkaloids, flavonoids, and apolar compounds. Rutin, quercetin, and swainsonine were detected by HPLC and GC/MS, respectively. Phosphorus, potassium, iron, and zinc were the inorganic elements found. Extracts produced cytotoxicity at all concentrations tested (7-4,000 mu g/ml) as evidenced by the colorimetric assay [3-(4,5-dimethyl-thiazol-2-yl) -2,5-diphenyl-tetrazolium bromide (MTT)]. Based upon the alkaline comet assay extracts were found to induce genotoxicity at concentrations ranging from 0.437 to 7 mu g/ml. DNA damage produced by extracts was affirmed using a modified comet assay with the enzymes Endo III and FPG in a concentration dependent manner. Further, enzyme-modified comet assay showed both oxidized purines and pyrimidines, and consequently oxidative stress was related to genomic instability and cell death. Data suggest that low concentrations of ethanolic extracts of S. planicaulis (different seasons) induced increased DNA damage related to oxidative stress and chemical composition.
