“…The low antiproliferative effect of the native drug obtained in our study is very well correlated with the duration of its intracellular retention. Free MTX is found to be pumped off the cell cytosol by P-glycoprotein, which participates in the development of resistance to antifolates [41]. Moreover, the availability of free MTX at its intracellular site of action depends on a passive diffusion mechanism, which can be limited by the high ionization state of MTX at physiological pH.…”

“…Липосомы получали из смесей природных фосфолипидов с пролекарствами и гликоконъюгатом стандартным методом экструзии через 100 нм-фильтры [8,9,21]. При этом образуются моноламеллярные (с единичным липидным бислоем) липосомы требуемого размера, несущие модифицированное лекарство и углеводный лиганд.…”

“…Схематически конструкция липосомы изображена на рисунке 1. Контакт с рецептором на поверхности клетки-мишени обеспечивается за счёт экспонирования углеводных групп SiaLe X на достаточном расстоянии от мембраны с помощью полярных гибких вставок ПЭГ(степень полимеризации [8][9][10][11][12][13][14].…”
