20.500.12556/RUL-132832 Toksičnost vodnih raztopin funkcionaliziranih kvarternih decilamonijevih kloridov Toxicity of aqueous solutions of functionalized quaternary decylammonium chlorides Kvarterne amonijeve soli so zaradi svoje rabe v vsakdanjem življenju razširjene, njihove lastnosti pa že dobro raziskane. V zadnjem času pa se vedno bolj poudarja njihov toksičen vpliv tako na ljudi kot druge organizme. O toksičnosti kvarternih decilamonijevih kloridov ni še veliko znanega, prav tako ne vemo kako funkcionaliziranost stranske alkilne verige na dušiku vpliva nanjo. Preučevali smo pet različno funkcionaliziranih kvarternih decilamonijevih kloridov: N-decil-N,N,N-trimetilamonijev klorid, N-(2-hidroksietil)-N-decil-N,N-dimetilamonijev klorid, N-(2-metoksietil)-N-decil-N,N-dimetilamonijev klorid, N-(2-(2-metoksietoksi)etil)-N-decil-N,N-dimetilamonijev klorid in N-(2-etoksi-2-oksoetil)-N-decil-N,N-dimetilamonijev klorid. Na primeru petih vrst plesni kot modelnih evkariontskih organizmov smo določali minimalno inhibitorno in minimalno fungicidno koncentracijo vodnih raztopin preučevanih organizmov. S teorijo gostotnega funkcionala smo izračunali porazdelitveni koeficient med n-oktanolom in vodo, ki nam služi kot mera lipofilnosti. Na koncu smo naredili še molekulsko sidranje preučevanih spojin na sedmih različnih encimih, ki so pomembni za delovanje modelnih organizmov. Quaternary ammonium salts are due to their use in everyday life widespread, with their properties widely studied. Recently is more and more emphasized their toxic effect on people as well on other organisms. Not much is known about toxicity of quaternary decylammonium chlorides, additionally we do not know how functionalization of a side alkyl chain on nitrogen affects it. We studied five differently functionalized quaternary decylammonium chlorides: N-decyl-N,N,N-trimethylammonium chloride, N-(2-hydroxyethyl)-N-decyl-N,N-dimethylammonium chloride, N-(2-metoxyethyl)-N-decyl-N,N-dimethylammonium chloride, N-(2-(2-metoxyethoxy)ethyl)-N-decyl-N,N-dimethylammonium chloride in N-(2-ethoxy-2-oxoethyl)-N-decyl-N,N-dimethylammonium chloride. In the case of five different species of mould as our model eukaryotic organism we have determined minimal inhibition and minimal fungicide concentration of aqueous solutions. With density functional theory we calculated n-octanol-water partition coefficient, which served us as a measure of lipophilicity. At the end we performed molecular docking of studied compounds on seven different enzymes that are important for activity of model organisms. površinsko aktivne snovi toksičnost lipofilnost molekulsko sidranje surfactants toxicity lipophilicity molecular docking true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2021-11-04 11:15:00 2021-11-04 11:15:05 2022-09-12 04:13:56 0000-00-00 00:00:00 2021 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 9621 88768771 Pogorelc_Eva_-_Toksicnost_povrsinsko_aktivnih_snovi.pdf Pogorelc_Eva_-_Toksicnost_povrsinsko_aktivnih_snovi.pdf 1 CFEF21DD7429EC60CBBBAEB428002995 c34d69249a177a08048a4be695532fe3d1d9d26b8a064f1c8a9597692961f226 093e348d-3d58-11ec-abdb-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=150553 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
