Ten 5-functionalized derivatives of 1,3-oxazole-4-carboxylate and 1,3-oxazole-4-carbonitrile were synthesized and their antiviral activities against the human cytomegalovirus (HCMV) were evaluated in vitro. Bioassays showed that seven compounds exhibited considerably higher antiviral activity (EC50:<0.05M) against a normal laboratory HCMV strain (AD-169) in human foreskin fibroblast cells than Ganciclovir (EC50=0.32M), an anti-HCMV agent in clinical use. Additionally, the HCMV-resistant isolate (GDGr K-17) was tested for sensitivity to 1,3-oxazole derivatives with most antiviral potency against the strain AD169. A one of them (5-((2-hydroxyethyl)(methyl)amino)-2-(4-methylphenyl)-1,3-oxazole-4-carbonitrile) showed very high potency (EC50:<0.05; CC50: >150 mu M, and SI50=3125) towards the resistant isolate compared to standard drugs Cidofovir (EC50=0.10 mu M, CC50: >30 mu M and SI50: <4). But, in contrast to the primary assays, the antiviral activity of these compounds against both the normal strain and the resistant isolate of HCMV were considerably less than one of Cidofovir in secondary assay. These results provided evidence that derivatives of 1,3-oxazole could be useful for developing new anti-HCMV drugs.

A new ionic liquid is synthesized, and its chemical structure is characterized by FTIR, 1D NMR and 2D NMR, and mass analyses. The thermal behavior and thermal stability of this ionic liquid are investigated. The results approved the formation of 4,4MODIFIER LETTER PRIME-trimethylene-N,NMODIFIER LETTER PRIME-dipiperidinium sulfate instead of 4,4MODIFIER LETTER PRIME-trimethylene-N,NMODIFIER LETTER PRIME-dipiperidinium hydrogen sulfate. Moreover, the synthesis of triazolo-pyrimidine derivatives was successfully conducted in the presence of new ionic liquid at room temperature under metal-free conditions, which demonstrated the catalytic efficiency of this ionic liquid. The workup was carried out without the utilization of high-cost column chromatography. After extraction of desired products, the residual ionic liquid could be recycled and reused in the next runs. New ionic liquid exhibited high catalytic activity even after fifth run with no significant change in the chemical structure.

Four isostructural dinuclear lanthanide complexes based on 4-azotriazolyl-3-hydroxy-2-naphthoic acid (H(3)ATNA) and 3-hydroxy-2-naphthoic acid (H(2)NA) ligands, {[Ln(2)(HATNA)(2)(HNA)(2)(H2O)(4)].6DMF} (Ln = Dy (1), Tb (2), Sm (3), Eu (4); DMF = N,N-dimethylformamide) have been prepared and characterized by X-ray diffraction crystallography, dc/ac magnetic characterization, and fluorescent spectrometry. The crystallographic data reveal dinuclear lanthanide cores of complexes 1-4, bridged by phenoxo and mu(1,3) carboxyl groups. Each nine-coordinated Ln(III) ion is located in a slightly distorted monocapped square antiprism. The ligand of H(3)ATNA displays a unique antenna effect in complex 4. Complexes 1-3 display only two ligand-centered fluorescent emissive peaks around 450 and 600 nm, and complex 4 shows four characteristic Eu(III)centered emission bands at 593, 618, 653, and 698 nm under excitation at 348 nm. Complex 1 exhibits single-molecule magnet behavior that is rationalized through ab initio calculations.

Farnesyl pyrophosphate synthase (FPS) is a key enzyme that catalyzes the formation of farnesyl pyrophosphate, the main initiator for rubber chain initiation in Hevea brasiliensis Muell. Arg. The transcriptional regulatory mechanisms of the FPS gene still not well understood. Here, a WRKY transcription factor designated HbWRKY27 was obtained by screening the latex cDNA library applied the HbFPS1 promoter as bait. HbWRKY27 interacted with the HbFPS1 promoter was further identified by individual Y1H and EMSA assays. HbWRKY27 belongs to group IIe WRKY subfamily which contains a typical WRKY domain and C-X5-CX23-HXH motif. HbWRKY27 was localized to the nucleus. HbWRKY27 predominantly accumulated in latex. HbWRKY27 was up-regulated in latex by ethrel, salicylic acid, abscisic acid, and methyl jasmonate treatment. Transient expression of HbWRKY27 led to increasing the activity of the HbFPS1 promoter in tobacco plant, suggesting that HbWRKY27 positively regulates the HbFPS1 expression. Taken together, an upstream transcription factor of the key natural rubber biosynthesis gene HbFPS1 was identified and this study will provide novel transcriptional regulatory mechanisms of the FPS gene in Hevea brasiliensis.

In the present study, the chemical structure of 4,4′-trimethylene-N,N’-dipiperidinium chlorosulfonate is elucidated by 1D NMR, and 2D NMR, FTIR, Raman analyses, and Mass spectra. It was indicated that the chlorosulfonic acid could not act as a sulfonating agent in the reaction with secondary amines like TMDP due to due more steric hindrance of the sulfur atom by chlorine and oxygen atoms. Raman and FTIR spectra are demonstrated as two high-value optical techniques to the elucidation and identification of chemical structures that confirmed C3(v) symmetry for chlorosulfonate anion in the ionic liquid. Then, the solvent-catalyst activity of ionic liquid was demonstrated in the one-pot synthesis of a series of novel triazolo-pyrimidines under mild conditions. The ionic liquid was retrieved and reused several times without reducing its catalytic efficiency. (C) 2020 Elsevier B.V. All rights reserved.

Salt stress is an important environmental factor affecting the growth and production of agricultural crops and fruits worldwide, including apple (Males x domestica). In this study, we demonstrate that a salt-responsive MYB transcription factor (TF), designated as MdMYB63, promotes survival under salt stress. Overexpression of MdMYB63 in apple calli significantly enhanced salt tolerance. Screening of the AP2/ERF family of TFs identified MdERF106 as an interaction partner of MdMYB63. Further analyses showed that the MdMYB63-MdERF106 complex significantly promotes the expression of downstream MdSOS1, thereby improving the Na+ expulsion and salt tolerance of apple. These functional analyses of MdMYB63 have provided valuable insights into the regulatory network of salt tolerance, and lay a theoretical foundation for the cultivation of new salt-tolerant apple varieties.

The ability to inhibit two important viruses is described. Two groups of polymers exhibited ability to totally inhibit the Zika virus. These polymers are derived from organotin dihalides and camphoric acid and lamivudine. This is the initial report of complete inhibition of the Zika virus by simple drugs. The ability to inhibit vaccinia virus is also reported. The inhibition of the vaccinia virus is shown by a number of organotin drugs including those also derived from lamivudine and camphoric acid and additional drugs derived from 3-amino-1,2,4-triazole, dicumarol, 4,6-diaminopyridine, alpha-cyano-4-hydroxcinnamic acid, and a variety of organotin polyethers including water soluble polymers derived from poly(ethylene glycol). All the drugs described in these studies are rapidly (< 30 s) synthesized using commercially available reactants at room temperature employing the interfacial reaction system that is employed industrially so that scale up to kilograms is relatively straight forward.

Drug-like inhibitors are often designed by mimicking cofactor or substrate interactions with enzymes. However, as active sites are comprised of conserved residues, it is difficult to identify the critical interactions needed to design selective inhibitors. We are developing an approach, named RADD (resistance analysis during design), which involves engineering point mutations in the target to generate active alleles and testing compounds against them. Mutations that alter compound potency identify residues that make key interactions with the inhibitor and predict target-binding poses. Here, we apply this approach to analyze how diaminotriazole-based inhibitors bind spastin, a microtubule-severing AAA (ATPase associated with diverse cellular activities) protein. The distinct binding poses predicted for two similar inhibitors were confirmed by a series of X-ray structures. Importantly, our approach not only reveals how selective inhibition of the target can be achieved but also identifies resistance-conferring mutations at the early stages of the design process.
