“…Thus, the selenocarbonyl compounds 1-11, shown in Table 1, have been examined in different biological studies at the ABCB1-overexpressing Colo 320/MDR-LRP resistant cell line, as well as the equivalent sensitive cell line (Colo 205 doxorubicin sensitive cells), following previously described methodologies 25,27,[34][35][36][37][38] . The selected derivatives 1-11 included the selenoanhydride 1 and the selenoesters 2-11, whose alkyl moiety contains different functional groups: a methyl group in 2-5, a methylcarbamoil group in 6, a methyloxycarbonylmethyl group in 7, a phenyloxycarbonylmethyl group in 8 and different ketonecontaining alkyl groups in 9-11.…”
