Human Immunodeficiency Virus (HIV) damages the immune system and leads to the life-threatening acquired immunodeficiency syndrome (AIDS). Despite the advances in the field of antiretroviral treatment, HIV remains a major public health challenge. Nucleosides represent a prominent chemotherapeutic class for treating viruses, however their cellular uptake, kinase-mediated activation and catabolism are limiting factors. Herein, we report the synthesis and in vitro evaluation of stavudine (d4T) ProTides containing polyfluorinated aryl groups against two strains; HIV-1 (IIIB) and HIV-2 (ROD). ProTide 5d containing a meta-substituted pentafluorosulfanyl (3-SF5) aryl group showed superior antiviral activity over the parent d4T and the nonfluorinated analogue 5a. ProTide 5d has low nano-molar antiviral activity; (IC50=30 nM, HIV-1) and (IC50=36 nM, HIV-2) which is over tenfold more potent than d4T. Interestingly, ProTide 5d showed a significantly high selectivity indices with SI=1753 (HIV-1) and 1461 (HIV-2) which is more than twice that of the d4T. All ProTides were screened in wild type as well as thymidine kinase deficient (TK-) cells. Enzymatic activation of ProTide 5d using carboxypeptidase Y enzyme and monitored using both P-31 and F-19 NMR is presented.

In this study, Fe3O4@graphite sheets were successfully synthesized in one-pot via a simple hydrothermal method and subsequently employed as an effective electrocatalyst for hydrogen evolution reaction (HER). HER is the crucial electrochemical reactions for the next-generation energy devices. Hydrogen is a clean and renewable energy resource and is one of the most promising candidates for fuel. The shape of the Fe3O4 nanoparticles is nearly spherical with a size of about 10 nm and the Fe3O4 nanoparticles distributed evenly on the graphite sheets. The synthesized Fe3O4@graphite sheets have a specific surface area about 125 m(2) g(-1) with slit-shaped open micro/mesopores. Overall the physicochemical characterization techniques have confirmed the formation, structural stability, and elemental composition of synthesized Fe3O4@graphite sheets. The resulting Fe3O4@graphite sheets were demonstrated towards electrocatalytic HER in 0.1 M KOH solution. The synthesized Fe3O4@graphite sheets delivered the lowest Tafel slope (78 mV dec(-1)) and overpotential (-120 mV(RHE)) at a current density of 10 mA cm(-2). The electrochemical impedance spectroscopy results demonstrate that HER are highly favorable on the Fe3O4@graphite sheets due to the relatively low charge transfer resistance. The experimental results reveal that Fe3O4@graphite sheets possess remarkable electrocatalytic HER activities and are highly stable. The good electrocatalytic activity of Fe3O4@graphite sheet can be ascribed to the synergistic effect between Fe3O4 and graphite sheets, which can facilitate charge transfer kinetics to enhance electrocatalytic HER performance.

We reported an efficient one-pot two-step synthesis of 3-(tert-butyl)-N-(4-methoxybenzyl)-1-methyl-1H-pyrazol-5-amine 3 in good yield by a solvent-free condensation/reduction reaction sequence starting from 3-(tert-butyl)-1-methyl-1H-pyrazol-5-amine 1 and p-methoxybenzaldehyde 2. The one-pot reductive amination proceeded by the formation in situ of the N-(5-pyrazolyl)imine 4 as key synthetic intermediate of other valuable pyrazole derivatives. This methodology is distinguished by its operational easiness, short reaction time, isolation and purification of the aldimine intermediate is not required. The structure of the synthesized N-heterocyclic amine 3 was fully characterized by FTIR-ATR, 1D and 2D NMR experiments, EIMS, and elemental analysis.

Genome sequencing of environmental bacteria allows identification of biosynthetic gene clusters encoding unusual combinations of enzymes that produce unknown natural products. We identified a pathway in which a ribosomally synthesized small peptide serves as a scaffold for nonribosomal peptide extension and chemical modification. Amino acids are transferred to the carboxyl terminus of the peptide through adenosine triphosphate and amino acyl-tRNA-dependent chemistry that is independent of the ribosome. Oxidative rearrangement, carboxymethylation. and proteolysis of a terminal cysteine yields an amino acid-derived small molecule. Microcrystal electron diffraction demonstrates that the resulting product is isosteric to glutamate. We show that a similar peptide extension is used during the biosynthesis of the ammosamides, which are cytotoxic pyrroloquinoline alkaloids. These results suggest an alternative paradigm for biosynthesis of amino acid-derived natural products.

Intermediates in aromatic amino acid biosynthesis can serve as substrates for the synthesis of bioactive compounds. In this study we used two intermediates in the shikimate pathway of Escherichia coli, chorismate and anthranilate, to synthesize three bioactive compounds: 4-hydroxycoumarin (4-HC), 2,4-dihydroxyquinoline (DHQ), and 4-hydroxy-1-methyl-2(1H)-quinolone (NMQ). We introduced genes for the synthesis of salicylic acid from chorismate to supply the substrate for 4-HC and the gene encoding N-methyltransferase for the synthesis of N-methylanthranilate from anthranilate. Polyketide synthases and coenzyme (Co)A ligases were tested to determine the optimal combination of genes for the synthesis of each compound. We also tested several constructs and identified the best one for increasing levels of endogenous substrates for chorismate, anthranilate, and malonyl-CoA. With the use of these strategies, 255.4 mg/L 4-HC, 753.7 mg/L DHQ, and 17.5 mg/L NMQwere synthesized. This work provides a basis for the synthesis of diverse coumarin and quinoline derivatives with potential medical applications.

In the search for novel aromatase inhibitors, a series of triazole and imidazole-based carbamate derivatives were designed and synthesized. Final compounds were thus evaluated against human aromatase by in vitro kinetic experiments in a fluorimetric assay in comparison with letrozole. The effect of most active derivatives 13a and 15c was then evaluated in vitro on the human breast cancer cell line MCF7 by MTT assay, cytotoxicity assay (LDH release) and cell cycle analysis, revealing a dose-dependent inhibition profile of cell viability and low micromolar IC50 values. In addition, docking simulations were also carried out to elucidate at a molecular level of detail the binding modes adopted to target human aromatase. (C) 2020 Elsevier Masson SAS.

To tackle leishmaniasis, search for efficient therapeutic drug targets should be pursued. Dihydrofolate reductase (DHFR) is considered as a key target for the treatment of leishmaniasis. In current study, we are interested in the design and synthesis of selective antifolates targeting DHFR from L. major. We focused on the development of new antifolates based on 3,4-dihydropyrimidine-2-one and 5-(3,5-dimethoxybenzyl)pyrimidine-2,4-diamine motif. Structure activity relationship (SAR) studies were performed on 4-phenyl ring of dihydropyrimidine (26-30) template. While for 5-(3,5-dimethoxybenzyl) pyrimidine-2,4-diamine, the impact of different amino acids (valine, tryptophan, phenylalanine, and glutamic acid) and two carbon linkers were explored (52-59). The synthesized compounds were assayed against LmDHFR. Compound 59 with the IC50 value of 0.10 mu M appeared as potent inhibitors of L. major. Selectivity for parasite DHFR over human DHFR was also determined. Derivatives 55-59 demonstrated excellent selectivity for LmDHFR. Highest selectivity for LmDHFR was shown by compounds 56 (SI = 84.5) and 58 (SI = 87.5). Compounds Antileishmanial activity against L. major and L. donovani promastigotes was also performed. To explore the interaction pattern of the synthesized compounds with biological macromolecules, the docking studies were carried out against homology modelled LmDHFR and hDHFR targets.
