dc.description.abstract | <p style="text-align: justify; ">Žučne kiseline, kao amfifilni molekuli pokazuju specifične osobine zbog čega predstavljaju interes proučavanja brojnih autora. U velikom broju studija je dokazana povezanost hromatografski dobijenog retencionog faktora molekula i njegove lipofilnosti. Lipofilnost molekula, kao značajna osobina na biofarmaceutskog stanovišta je zbog toga postavljena kao ključni parametar koji se koristi u QSAR ispitivanjima. za postavljanje matematičkih modela. Ovaj rad je podeljen na tri dela, sa sledećim podnaslovima: hromatografski retencioni faktor kao merilo hidrofobnosti žučnih kiselina, uticaj elektrolita na hidrofobnost žučnih kiselina kao i modelovanje particionog koeficijenta probnog molekula (nitrazepama) u micele žučnih kiselina uz pomoć temperaturne zavisnosti retecionog indeksa žučnih kiselina. Retencioni koeficijent žučnih kiselina dobijeni hromatografijom pokazali su se kao veoma pogodni za opisivanje ponašanja žučnih kiselina u eksperimentima gde dolazi do izražaja promena odnosa hidrofobne i hdrofilne površine steroidnog skeleta i postavljen je i matematički model za particioni koeficijent probnog molekula (nitrazepama) u micele žučnih kiselina na različitim temperaturama.</p> | sr |
dc.description.abstract | <p>Bile acids, as amphiphiles posess specific features of the great interest for researchers. Connection between chromatografically obtained retention index and bile acids' lipophilicity is proven in a lot of studies. Lipophilicity is important feature of one molecule accoding to biopharmaceutical aspect and that is why it is chosen as a main parameter in QSAR studies for deriving mathematical models. This work is divided in three parts: chromatographic retention factor as a measure of bile acids' hydrophobicity, influence of electrolytes on bile acids' hydrophobicity, and modeling of partition coefficients of the probe molecule (nitrazepam) in bile acids' micelles using temperature dependence of bile acids on retention coefficient. Retention coefficients of bile acids obtained using chromatography is shown to be convinient for describing behavior of bile acids especially in experiments in which the change of the ratio between hydrophobic and hydrophilic surface of the steroid sceleton is important. Mathematical model is derived for partition coefficient of the probe molecule (nitrazepam ) in bile acids micelles on different temperatures.</p> | en |
