Joshi, Vinay G.;Chindera, Kantaraja;Bais, Manish V.;Sajjanar, Basavaraj;Tiwari, Ashok K.;Kumar, Satish research published 《 Novel peptide (RATH) mediated delivery of peptide nucleic acids for antiviral interventions》, the research content is summarized as follows. The peptide nucleic acid (PNA) is a chimeric mol. with the nucleobases connected by peptide bonds. This chimeric nature gives the PNA certain therapeutic advantages over natural antisense nucleic acid mols. The PNA probes are known for its better and stronger complementation with target nucleic acids. However, cellular delivery of PNA is a major hurdle due to the charge-neutral nature of the PNA. For cellular delivery of PNA, peptide-PNA conjugates are used. This approach may face some practical limitation in terms of PNA antisense activity. In this study, we propose a novel RATH-2 peptide-based non-covalent PNA delivery mechanism. We observed RATH-2 shows a favorable mol. interaction with PNA at 16:1 (peptide:PNA) molar ratio resulting in co-centric nanoparticle formation. With this combination, we could achieve as high as 93% cellular delivery of the PNA. The proposed non-covalent RATH:PNA delivery model showed endocytic entrapment free delivery of PNA. The study further demonstrated the therapeutic application of PNA with in vitro antiviral intervention model. Using RATH-2 non-covalent PNA delivery system, we could inhibit 69.5% viral load. The present study demonstrates a cell-penetrating peptide:PNA interaction can lead to nanoparticle formations that facilitated cellular delivery of PNA.

Cloud loss and pulp precipitation are serious quality defects of mandarin juice (MJ) which brake on industrialization and need to be overcome by developing stabilization process. Therefore, filtration (FT) and standard homogenization (SH) on improving the cloud stability of MJ and minimizing the loss of major qualities were investigated. The FT-SH combined treatment effectively decreased the minimal particle size below 15μm and sedimentation rate by 17.30%-74.40%, and increased the cloud value from 7.97% to 332.57%, results in more uniformity and cloud stability of MJ. Moreover, FT reduced the pectin methylesterase (PME) activity by 34.19%-50.96%, browning (ΔE* < 3), free and bound phenol contents (27.81% and 59.13%), and aroma intensity (p < 0.05). SH released the free phenols from bound phenols association with cloudiness. The optimum stabilization condition was considered as the 100-mesh + 20 MPa that was obviously improved the cloudiness and minimizing the color, polyphenol and aroma loss.

Jalloul, Amel ben;Chaar, Hatem;Tounsi, Moufida Saidani;Abderrabba, Manef research published 《 Variations in phenolic composition and antioxidant activities of Scabiosa maritima (Scabiosa atropurpurea sub. maritima L.) crude extracts and fractions according to growth stage and plant part》, the research content is summarized as follows. This study aimed to assess for the first time how growing stage and plant part affect the phytochem. contents and antioxidant capacities of extracts and fractions of Scabiosa Atropurpurea sub. Maritima L. (S.maritima). An experiment was conducted on the different parts (leaves, stem, roots, inflorescences, and fruits) of plants collected from the Zaghouan region, Tunisia, at different growing stages: vegetative stage (March), early budding stage (Apr.), late flowering stage (May) and late maturing stage (June). The various plant parts were subjected to hydro-methanolic extraction and sequential solvent fractionation (Chloroform and Acetate). For each extract or fraction, content of total phenolics (TPC), flavonol, tannin (CTC) and total flavonoids (TFC) were quantified. The antioxidant activity of different extracts was assessed using total antioxidant capacity (TAC), ferric reducing power (FRAP), 1, 1-diphenyl-2-picryl hydrazyl (DPPH) and 3-ethylbenzothiazoline-6-sulfonic acid (ABTS) radical scavenging activities. A Multiple Factor Anal. (MFA) and hierarchical clustering were done on the data set obtained from the various measurements. Addnl., the chem. composition of five selected crude extracts was determined by high performance liquid chromatog. coupled with a diode array (HPLC-DAD). Phytochem. compounds (phenolic, flavonoids, flavonol and tannin) and antioxidant activities (TAC, FRAP, ABTS and DPPH) of S.maritima extracts and fractions differ among plant parts and change throughout the growing stages. The highest phytochem. content and antioxidant activities of plant parts during the different growing stages were mainly recorded in acetate fractions. Leaves generally exhibited higher phytochem. content and antioxidant activity compared to other plant parts. Their highest values were reached during flowering season (plants collected in May). Unlike leaves and stem, roots exhibited their highest phytochem. content and antioxidant activity in June. The MFA results distinguished leaf samples from the other plant parts and highlighted a strong correlation between phytochem. content and antioxidant capacity. High levels of catechin hydrate (ranging from 1951.86 to 6748.97 mg/100 g of extract) were recorded in all samples. Leaf samples were found to contain high amounts of luteolin-7-O glucoside and kaempferol-3-O-rutinoside while particularly high contents of resorcinol and catechol (226.00 and 57.71 mg/100 g of extract, resp.) were observed in the stem sample.

Jacobsson, Erik;Peigneur, Steve;Andersson, Haakan S.;Laborde, Quentin;Strand, Malin;Tytgat, Jan;Goeransson, Ulf research published 《 Functional Characterization of the Nemertide α Family of Peptide Toxins》, the research content is summarized as follows. Peptide toxins find use in medicine, biotechnol., and agriculture. They are exploited as pharmaceutical tools, particularly for the investigation of ion channels. Here, we report the synthesis and activity of a novel family of peptide toxins: the cystine-knotted α nemertides. Following the prototypic α-1 and -2 (1 and 2), six more nemertides were discovered by mining of available nemertean transcriptomes. Here, we describe their synthesis using solid phase peptide chem. and their oxidative folding by using an improved protocol. Nemertides α-2 to α-7 (2-7) were produced to characterize their effect on voltage-gated sodium channels (Blatella germanica BgNa_V1 and mammalian Na_Vs1.1-1.8). In addition, ion channel activities were matched to in vivo tests using an Artemia microwell assay. Although nemertides demonstrate high sequence similarity, they display variability in activity on the tested Na_Vs. The nemertides are all highly toxic to Artemia, with EC₅₀ values in the sub-low micromolar range, and all manifest preference for the insect BgNa_V1 channel. Structure-activity relationship anal. revealed key residues for Na_V-subtype selectivity. Combined with low EC₅₀ values (e.g., Na_V1.1: 7.9 nM (α-6); Na_V1.3: 9.4 nM (α-5); Na_V1.4: 14.6 nM (α-4)) this underscores the potential utility of α-nemertides for rational optimization to improve selectivity.

Compounds I exerted their antiproliferative activity by inducing the cell cycle arrest (elevated p53 and downregulated cyclin-dependent kinase 1 (cdk1)) and inducing apoptosis (elevated caspase 3). Compounds I [R = HC=CHPh, etc.; X = S; Y = H] and II [R¹R² = CH₂CH₂] exerted their activity by inhibiting the growth and proliferation of cancer cells through inhibiting both topoisomerase II (topoII) and thioredoxin reductase1 (txnrd1).
