Modifying the N-terminus of polyamides: PyImPyIm has improved sequence specificity over f-ImPyIm

Seven N-terminus modified derivatives of a previously published minor-groove binding polyamide (f-ImPyIm, 1) were synthesized and the biochemical and biophysical chemistry evaluated. These compounds were synthesized with the aim of attaining a higher level of sequence selectivity over f-ImPyIm (1), a previously published strong minor-groove binder. Two compounds possessing a furan or a benzofuran moiety at the N-terminus showed a footprint of 0.5 muM at the cognate ACGCGT site (determined by DNase I footprinting); however, the specificity of these compounds was not improved. In contrast, PyImPyIm (4) produced a footprint of 0.5 muM but showed a superior specificity using the same technique. When evaluated by thermal melting experiments and circular dichroism using ACGCGT and the non-cognate AAATTT sequence, all compounds were shown to bind in the minor-groove of DNA and stabilize the cognate sequence much better than the non-cognate (except for the non-amido-compound that did not bind either sequence, as expected). PyImPyIm (4) was interesting as the DeltaTm for this compound was only 4 C but the footprint was very selective. No binding was observed for this compound with a third DNA (non-cognate, ACCGGT). ITC studies on compound 4 showed exothermic binding with ACGCGT and no heat change was observed for titrating the compound to the other two DNA sequences. The heat capacity (DeltaCp) of the PIPI/ACGCGT complex calculated from the hydrophobic interactions and SASA calculations was comparable to the experimental value obtained from ITC (-146 cal mol-1 K-1). SPR results provided confirmation of the sequence specificity of PyImPyIm (4), with a Keq value determined to be 7.1 ¡Á 106 M-1 for the cognate sequence and no observable binding to AAATTT and ACCGGT. Molecular dynamic simulations affirmed that PyImPyIm (4) binds as a dimer in an overlapped conformation, and it fits snugly in the minor-groove of the ACGCGT oligonucleotide. PyImPyIm (4) is an especially interesting molecule, because although the binding affinity is slightly reduced, the specificity with respect to f-ImPyIm (1) is significantly improved.

Essential Oil Composition of Three Globularia Species

The chemical composition of the essential oils obtained by hydrodistillation from the aerial parts of Globularia cordifolia L., G. meridionalis (Podp.) O.Schwarz, and G. punctata Lapeyr. was characterized by GC-FID and GC/MS analyses. Among the 33 identified compounds, the most abundant present in all investigated samples were oct-1-en-3-ol (2.9-47.0%), 6-(1,5-dimethylhex-4-enyl)-3-methylcyclohex-2-enone (8.2-40.9%), and fukinanolid (7.4-31.6%). Multivariate statistical analyses (PCA and HCA) of the hitherto studied Globularia volatile compounds confirmed to some extent the assumed phylogenetic relationships of the Globularia species studied, including the close relationship between the morphologically similar species G. cordifolia and G. meridionalis, but also evidenced several discrepancies in the current classification of Globularia species.

Solvent-free synthesis of 2-amino-5-aryloxymenthyl-1,3,4-thiadiazoles and their coumarin or benzofuran bis-heterocyclic derivatives

2-amino-5-aryloxymethyl-1,3,4-thiadiazoles were synthesized rapidly by a microwave-accelerated solvent-free procedure in high yield via the condensation of thiosemicarbazide with aryloxyacetic acids using poly(ethylene glycol)-supported dichlorophosphate as a dehydration reagent. The solvent-free N-acylation of 2-amino-5-aryloxymethyl-1,3,4-thiadiazoles with coumarin-3-carboxylic acid chloride or benzofuran-2-carboxylic acid chloride efficiently afforded corresponding bis-heterocyclic derivatives, 2-(coumarin-3-carboxamido)-5-aryloxymethyl-1,3,4-thiadiazoles, and 2-(benzofuran-2-carboxamido)-5-aryloxymethyl-1,3,4-thiadiazoles. The strategy has advantages of no organic solvent pollution, an elevated reaction rate, an improved yield, and a simple work-up procedure. Copyright Taylor & Francis LLC.

Engineering Pseudomonas putida KT2440 for simultaneous degradation of carbofuran and chlorpyrifos

Currently, chlorpyrifos (CP) and carbofuran are often applied together to control major agricultural pests in many developing countries, in most cases, they are simultaneously detected in agricultural soils. Some cost-effective techniques are required for the remediation of combined pollution caused by multiple pesticides. In this work, we aim at constructing a detectable recombinant microorganism with the capacity to simultaneously degrade CP and carbofuran. To achieve this purpose, CP/carbofuran hydrolase genes and gfp were integrated into the chromosome of a biosafety strain Pseudomonas putida KT2440 using a chromosomal scarless modification strategy with upp as a counter-selectable marker. The toxicity of the hydrolysis products was significantly lower compared with the parent compounds. The recombinant strain could utilize CP or carbofuran as the sole source of carbon for growth. The inoculation of the recombinant strain to soils treated with carbofuran and CP resulted in a higher degradation rate than in noninoculated soils. Introduced green fluorescent protein can be employed as a biomarker to track the recombinant strain during bioremediation. Therefore, the recombinant strain has potential to be applied for in?situ bioremediation of soil co-contaminated with carbofuran and CP.
