The antibacterial effect of the endotoxin-binding Sushi peptides against Gram-negative bacteria GNB is investigated in this study. Similar characteristics observed for Atomic force microscopy AFM images of peptide-treated Escherichia coli and Pseudomonas aeruginosa suggest that the Sushi peptides S3 evoke comparable mechanism of action against different strains of GNB.
The results also indicate that the Sushi peptides appear to act in three stages: damage of the bacterial outer membrane, p Synthesis, characterization and antibacterial activity of guanidinylated chitosan.

Ying Hu 7 Estimated H-index: 7. Polymethylene-co-guanidine based capsules: a mechanistic study of the formation using alginate and cellulose sulphate. Renken 1 Estimated H-index: 1. Capsules have been prepared based on a polyanion blend of sodium alginate and sodium cellulose sulphate, gelled in the presence of calcium chloride and sodium chloride. In a second step a membrane was formed via the addition of polymethylene-co-guanidine PMCG , an oligocation.
A mechanistic study examined the influences of pH, ionic strenght, gelation and reaction times as well as the molar mass of the polyanions on the transport and mechanical properties.

The kinetic parameters of each stage were calculated from the Kissinger, Friedman and Flynn-Wall-Ozawa methods. The Chang method was also used for c Meincken 1 Estimated H-index: 1. The influences of the antibacterial magainin 2 and PGLa from the African clawed frog Xenopus laevis and the hemolytic bee venom melittin on Escherichia coli as the target cell were studied by atomic force microscopy AFM.
Nanometer-scale images of the effects of the peptides on this gram-negative bacterium's cell envelope were obtained in situ without the use of fixing agents. These high-resolution AFM images of the surviving and intact target cells before and after peptide treatment showed d Takao Obokata 5 Estimated H-index: 5. On the basis of the assignment, we developed new methods to determine the content of four-membered azetidinium ring AZR and number-average degree of polymerization DPn of the repeating unit of PAE by using NMR. Structure-activity relationships of oligoguanidines-influence of counterion, diamine, and average molecular weight on biocidal activities.

Estimated H-index: 4. A series of different oligomeric guanidines was prepared by polycondensation of guanidinium salts and four different diamines under varying conditions. The antimicrobial activities were evaluated against two to four microorganisms. It was found that in each case three major product type series are dominating.

These series are linear and terminated with one guanidine and one amino group type A , two amino groups type B , or two guanidine Interactions between dendrimer biocides and bacterial membranes. Chris Zhisheng Chen 3 Estimated H-index: 3. Abstract Dendrimer biocides have been shown to be more potent than their small molecule counterparts. In this study, several techniques were utilized to investigate the interactions between quaternary ammonium functionalized poly propylene imine dendrimers and bacterial membranes.
Both Gram-positive and Gram-negative bacteria were tested. The techniques employed include UV—Vis spectroscopy, differential scanning calorimetry, and bioluminescence. When treated with dendrimer biocides, release of Published on Nov 1, in Fibre Chemistry 0. Aleshina 2 Estimated H-index: 2.
Estimated H-index: 3. Estimated H-index: 2. Comparative studies of the production conditions and properties of polyvinyl alcohol spinning solutions containing the proteolytic enzyme protease C, the polycationic antimicrobial polyhexamethylene guanidine hydrochloride or polyhexamethylene guanidine phosphate, and in some cases sodium alginate, were conducted. It was found that addition of protease C, polyhexamethylene guanidine hydrochloride, polyhexamethylene guanidine phosphate, and alginate to a polyvinyl alcohol water-alcohol solution, Cited By Physicochemical and barrier properties of polylactide films including antimicrobial additives.
