Toxicologie génétiqueIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Two new derivatives (A) and (B) of cationic germanium metal based surfactants have been synthesized. Their formulas are: [GeCl2(R)4]2+FeCl4 2– and [GeCl2(R\)4]2+SnCl4 2–·2H2O where R = hexamine and R\ = isothiouronium. A third derivative (C) of cationic titanium metal based surfactant was also synthesized and its formula is: [TiCl2(R\\)2]2+CoCl4 2–·6H2O where R\\ = triphenylphosphine. The presence of complex anions with metals was confirmed by inductive coupled plasma spectroscopy (ICP), IR spectrum and elemental analysis. Surface properties of the prepared surfactants, surface tension and critical micelle concentration were evaluated. Cytotoxic activities of these three metallo-surfactants were tested on human cell lines: leukemia lymphoblastic NALM-6 cells, promyelocytic HL-60 cells and breast adenocarcinoma MCF-7 cells. The obtained data revealed that the compound A did not exert cytotoxicity toward normal lymphocytes and was also inactive against all tumor cell lines tested. However, compounds B and C displayed high cytotoxicity in tumor cells and low toxicity in human normal lymphocytes, with concurrent high genotoxicity in all kinds of cells. All of these synthesized metallo-surfactants (A, B and C) induced oxidative DNA damage as detected by alkaline comet assay. Therefore, novel cationic germanium and titanium metal based surfactants (B and C) may be considered for use as anticancer drugs but further studies should be performed.

Langues : Anglais (eng) Tags : Nitrogen heterocycles Aziridine Azepane derivatives Critical micelle concentration Surface tension Antimicrobial activity Surfactants Index. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Four of new tin(IV) compounds derived from aziridine and azepane substituents have been synthesized and characterization by elemental microanalysis, atomic absorption, FT-IR and 1H-NMR spectroscopy. These tin-derived compounds exhibited biocidal activities on four different microorganisms: Escherichia coli, Staphylococcus aureus, Candida albicans and Aspergillus niger. The use of common and effective biocides depends on the surfactant molecules. On this basis, surface tension measurements were used to determine the critical micellar concentration (cmc), the minimum average area per surfactant molecule (Amin) and the surface excess concentration (L8). A direct relationship has found between the antimicrobial efficacy and L8. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=3033

ThixotropieIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : Hypochlorous acid (HClO) is formed in the white blood cells of all mammals. As part of a mechanism that developed several millions of years ago, it also helps the human body to protect against pathogens that enter it. This makes the weak acid a nature-based option for disinfection. Despite this, a disadvantage of water-thin solutions of hypochlorous acid is that they have significantly limited anti-microbial potential due to the reduced contact time. Hydrogels overcome this limitation and lead to improved and more sustainable use. Due to the high reactivity of hypochlorous acid, common additives such as polymer thickeners and natural clays are not suitable. Synthetic smectite clays – of which the presented PURABYK-R 5500 is one example – are very similar in structure to natural clays. However, due to their subsequent technical development, synthetic smectite clays exhibit better stability and are therefore very well suited to forming these hydrogels. They stabilize the hypochlorous acid in the required pH value range and are free from components that impair the activity of HClO. These unique additives are produced under controlled conditions from naturally occurring inorganic mineral sources. They offer the possibility of using structures from nature, paired with a very high purity and consistent quality. Their great potential is presented here using PURABYK-R 5500 as an example.

The chromatographic system comprised of soil-cellulose (3:7, w/w) as stationary phase and mixed micellar solution (sodium deoxycholate-sodium dodecyl sulfate, 1.0% each in 1:1 ratio) containing M5-acetonitrile in 3:2 ratio (v/v) was identified as the best mobile phase for separation and migration of transition metal ions. The Rf value for the metals follows the order, Cu(II) (0.15) < Ag(I) (0.57) < Au(III) (0.91) which also happens to be the order of increasing atomic weight of the metal ions in the periodic group. The detection limit of Cu(II), Ag(I), and Au(III) was found to be 0.22, 1.48, and 7.76 μg zone–1 respectively. The proposed method is robust, sensitive, easy, and reproducible. It has been used for successful identification and separation of above mentioned cations in sample matrices. Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=11928

Glycolipides
LipopeptidesIndex. décimale : 668.1 Agents tensioactifs : savons, détergents Résumé : A considerable number of biosurfactants have been investigated for their antibacterial, antifungal or antiviral activity that is mostly based on the ability to destroy microbial cell membranes. In addition, some of them are also able to inhibit the adhesion of microorganisms to surfaces and tissues. Although these antimicrobial properties can be generally explained by a strong detergency effect, there are further mechanisms, such as the interaction with membrane phospholipids or the alteration of the electrical conductance of membranes, resulting in the damage of microbial cells. Typically, antimicrobially active biosurfactants are glycolipids (e.g. rhamnolipids) or cyclic lipopeptides (e. g. Polymyxin). Since most of these substances were not available in larger quantities in the past, their potential applications in cleaners and cosmetics was not studied intensely, however, their versatility and the possibility of combining different properties, such as cleaning and antimicrobial effects, suggest a further consideration of biosurfactants even for mass-market products.
