A ruthenium complexes of monastrol and its pyrimidine analogues: Synthesis and biological properties
2019
AbstractA new series of mononuclear ruthenium(II) complexes of the type [Ru(PPh3)2(N,S-L1–3)2] 2H3O+.(Cl−)2.XH2O, [RuCl(dmso)3(N,S-L1–3)], and [Ru2(Cl−)2(N,S-L1–3)2].XH2O, where L1 is ethyl 4-(3-hydroxyphenyl)-6-methyl-2-thioxo-pyrimidine-5-carboxylate (monastrol), and L2 and L3 are the 4-hydroxyphenyl and 4-bromophenyl analogs of monastrol have been prepared and characterized by elemental analysis, 1H, and 13C NMR spectroscopy. All the complexes were assayed for their anti-HIV-1 and HIV-2 activity in MT-4 cells, and cytotoxicity was also investigated in mock-infected in MT-4 cells by using MTT assay. All the complexes exhibited no anti-HIV activity, however complexes [RuCl(dmso)3(N,S-L1)] (7) and [RuCl(dmso)3(N,S-L2)] (8) showed cytotoxicity values of > 0.21 and > 2.14 µM, respectively against mock-infected MT-4 cells. In addition, complexes [Ru(PPh3)2(N,S-L3)2].2H3O+.2Cl−.H2O (4), 7, and [RuCl2(N,S-L1)] (10) have been selected for evaluation of their dual inhibition activity against dual-specificity tyr...
