摘要：

In this study, we investigated the effect of amine- and hydroxyl-terminated Generation 2 and 3 (G2 and G3) poly(amidoamine) (PAMAM) dendrimers on the viability and induction of apoptosis in human MCF-7 and MDA-MB-231 breast cancer cells. It was shown that amino-terminated PAMAM dendrimers were cytotoxic, with IC50 value after 24 hr of incubation in MCF-7 and MDA-MB-231 breast cancer cells 153 +/- 3 mu M and 140 +/- 2 mu M for G2 PAMAM and 120 +/- 3 mu M and 99 +/- 2 mu M for G3 PAMAM, respectively. Experiments made with annexin V-fluorescein isothiocyanate (V-FITC) and detection of apoptosis by a fluorescent microscopy assay revealed that G2 and G3 PAMAM-NH2 dendrimers inhibited the proliferation of MCF-7 and MDA-MB-231 malignant cells by increasing the number of apoptotic and necrotic cells. The cytotoxic and apoptotic effect of G2 and G3 PAMAM-OH dendrimers was significantly weaker.
