Honey is an excellent source of polyphenolic compounds that are effective in attenuating quorum sensing (QS), a chemical process of cell-to-cell communication system used by the opportunistic pathogen Pseudomonas aeruginosa to regulate virulence and biofilm formation. However, lower water solubility and inadequate bioavailability remains major concerns of these therapeutic polyphenols. Its ther...

We present here a new, general, solid phase strategy for the synthesis of sequence independent peptidyl-fluoromethyl ketones using standard Fmoc peptide chemistry. Our method is based on the synthesis of bifunctional linkers which allows the incorporation of amino acid fluoromethyl ketone unit at the C-terminal end of peptide sequences. Application of this approach for the synthesis of activity...

Small ubiquitin-like modifier (SUMO)-specific proteases (SENPs) that reverse protein modification by SUMO are involved in the control of numerous cellular processes, including transcription, cell division, and cancer development. However, the physiological function of SENPs in energy metabolism remains unclear. Here, we investigated the role of SENP2 in fatty acid metabolism in C2C12 myotubes a...

Selenium nanoparticles (SeNPs) were fabricated using a green microwave technique in the presence of ascorbic acid. The morphological features indicated that semi-spherical SeNPs with diameter 8.5–22 nm configured agglomerated spherical shapes diameters around 0.47–0.71 μm. Furthermore, removal Fuchsin Basic dye from aqueous solutions was investigated upon variation concentration SeNPs. degradat...

The modification of proteins by SUMO (small ubiquitin-related modifier) plays important roles in regulating the activity, stability and cellular localization of target proteins. Similar to ubiquitination, SUMO modification is a dynamic process that can be reversed by SENPs [SUMO-1/sentrin/SMT3 (suppressor of mif two 3 homologue 1)-specific peptidases]. To date, six SENPs have been discovered in...

Vitamin D receptor (VDR) is a substrate for modification with small ubiquitin-like modifier (SUMO). To further assess the role of reversible SUMOylation within the vitamin D hormonal response, we evaluated the effects of sentrin/SUMO-specific proteases (SENPs) that can function to remove small ubiquitin-like modifier (SUMO) from target proteins upon the activities of VDR and related receptors. ...

Förster resonance energy transfer (FRET) technology has been widely used in biological and biomedical research, and it is a very powerful tool for elucidating protein interactions in either dynamic or steady state. SUMOylation (the process of SUMO [small ubiquitin-like modifier] conjugation to substrates) is an important posttranslational protein modification with critical roles in multiple bio...

Background and purpose: Polycaprolactone nanocapsules incorporated with triazole derivatives in the presence absence of selenium nanoparticles were prepared evaluated as antiproli­ferative anticancer agents. using emulsion technique. Experimental approach: The capsules characterized FT-IR, TEM DLS measurements. synthesized triazo­lopyrimidine derivative encap­sulated polycaprolactone was tested...
