[AuIIIX2(dtc-Sar-Aib3-O(t-Bu))] (X = Br (4a)/Cl (4b)), and [AuIIIX2(dtc-Sar-Aib3-Gly-OEt)] (X = Br (5a)/Cl (5b)) (Aib = “alpha”-aminoisobutyric acid, 2-methylalanine) were designed to obtain metal-based peptidomimetics that may specifically target two peptide transporters (namely, PEPT1 and PEPT2) upregulated in several human tumor cells. All the compounds were characterized by means of FT-IR and mono- and multidimensional
作为我们研究工作的进一步扩展,重点是开发寡肽金(III)-二硫代氨基甲酸酯dtc衍生物作为潜在的抗癌剂,其配合物[Au III X 2(dtc-Sar- 1 -Ser(t -Bu)-O(吨-Bu))(X = Br的(1A)/氯(1B)),[金III X 2(DTC-AA-AIB 2 -O(吨-Bu))](AA = SAR(肌氨酸,ñ -甲基甘氨酸),X = Br(2a)/ Cl(2b); AA = d,1- Pro,X = Br(3a)/ Cl(3b)),[Au III X2(dtc-Sar-Aib 3 -O(t -Bu))](X = Br(4a)/ Cl(4b))和[Au III X 2(dtc-Sar-Aib 3 -Gly-OEt)] (X = Br(5a)/ Cl(5b))(Aib =“α”-氨基异丁酸,2-甲基丙氨酸)被设计用于获得基于金属的肽模拟物,可以专门针对两个上调的肽转运
